File Browser

On the left side of the Titan interface, you will find the File Browser. It consists of two parts; the top part is where you select a folder, the bottom part will then show all printable files in the selected folder.

Selecting a file

By default, the initial folder is the users home folder. When an entry in the browserlist has a triangle, it contains subfolders. By clicking the triangle you open or close the subfolder view.

As soon as you click a folder that contains printable images (TIF and JPG) they will show up in the Picture list with a thumbnail displayed, the file name and the original size and resolution.

Only files that can be printed will show up in the File Browser.

To access an external drive or a network connected drive, use the Folder Popupmenu at the top.

When you have found the image(s) you want to print, you can drag them to the free layout or Template, depending on which tab panel you are.

File Details

File details can be made visible by increasing the size of the File Browser. This can be done by dragging the dark grey vertical line to the right of the File Browser. When you drag it to the right, the popup menu appears that allows you to select None (Default), File Dimensions (in mm) or File Size (in MB)

The size of the thumbnails can be changed by dragging the slider above the thumbnails.






Top Menu: Server, Printer and Paper selection

At the top of the screen, you will find important controls that work in combination with all the tabs.
Server Button Titan should connect to your server automatically on launch, but you can also connect to the server manually. To do so, click on the server button and browse to your Gemini12 server on your network (you may have to mount the drive first). After mounting, select the Gemini folder and open it. Starting Titan version 1.2 auto-connect connects to your server automatically, so this button is no longer used.
The green light indicates you are connected to the Gemini12 server. If it is red, you are not connected to the Gemini12 server.
Please note this led will stay red if you are remote printing from a network on which a Gemini12 server is not available. Remote Printing is always available, as long as you have an internet connection.

Printer Popup Menu In this popup menu, you will find the available printers you can print to. If only Gemini Remote is shown there, you are not connected to a Gemini12 server on your network.

Paper Popup Menu  After selecting a printer, the Paper popup menu will be updated with the available paper types on the selected printer.

You cannot print until you select both a printer and paper.



On the right hand side of the Titan interface the status of your connected printers are listed (up to 4 printers)

When selected, the loaded paper and width are shown. For each printer the jobs are also displayed; Active is the jobs now in the Active queue waiting to be printed or printing. Hold should be 0; any higher number means that jobs are on hold. This could be because their size is larger than the loaded media, or the media type does not match the loaded media.

Supported files

Titan supports several file types; Only TIF and JPG are preferable, but limited support is also provided for PDF, PSD, BMP, PNG, EPS, PS and some Raw files, although Raw files are not print ready usually, so use at your own risk. PDF support is limited to 1 Page files. Many other bitmap format do not contain icc color information and are not really intended for professional printing and can give errors or unexpected prints.

File sizes and DPI

Although your printer can obtain high resolutions like 1440 dpi, it only slows down and creates problems if you upsample images to beyond 300 dpi. For 99.9% of the images, you will not be able to see the difference between a 300 dpi print and a 600 dpi print. The difference is that the 600 dpi is 4x bigger in file size and will take 4x longer to process, whilst doing nothing for sharpness. For small prints it sometimes can be usefull to use a higher resolution, but large prints can usually not be over 300 dpi.

Currently, Titan supports files up to 410 Megapixels. (image width x image height).

Images beyond 30000 pixels can create problems, and aren’t even support by slightly older Photoshop versions. If you get a warning from Titan during printing, try sampling the image down to a normal resolution like 300 dpi, and you will be able to print at least 64” portrait photo’s.

For Large Format prints, an image resolution of 150 dpi is recommended. For small prints (A4 and below) it is better to use 300 dpi. Using resolutions over 300 dpi is ofcourse possible, but will not add much sharpness, and could cause errors.

View Server Button

Unless you are running Titan on the Gemini12 server, it will have a View Server button (unless you have no Gemini 12 server in your network) Clicking this button opens a remote view to the Gemini 12 server, allowing you to view and alter setting, start queues and perform any other server related tasks.

Tabbed Interface

The Tabbed interface allows you to choose many different sub-interfaces with specific functions.

There are currently six different tabs available. Each tab is covered below:

Template Tab


Titan supports templates for jobs that are repetitive or multiple file. The template files from Gemini 4 can be used in Titan, so if you have upgraded from Gemini 4, there is no need to re-create your templates. On the left side the list of available templates is shown, both by their name as by a thumbnail preview. You can set the size of the preview using the Slider.

Importing templates

Gemini 4 and Titan templates can be imported using the Import button. If Gemini 4 is installed, clicking Import will open up the folder where your Gemini 4 templates are stored. (On Mac that is /Library/Application Support/EPSON/PPPS/Templates). If you have stored your templates on the server, they can be copied from there.


If you have many templates, you can filter the list using the Filter PopupMenu. For Passport pictures there is a special filter, which shows the 25 built in templates for Passports. New Passport templates can be added using the Template Editor tab.

Using Templates

To start using a template, you click on it in the list. The larger preview on the right then shows your template. Each template cell has a blue box indicating its position and size. The letter in the cell indicates which image will be placed there; if all cells are A, they will all receive the same image. When the cell letter is different, a subsequent image will be placed there.

To see how this works, drag a few images to the Large Template preview and drop them on the cell you want. They will be loaded immediately. You can select muliple files in the file browser and drag the selection onto a template. This will fill the cells of a template and add additional pages if required. You can select all files in a folder using Ctrl-A (Windows) or CMD-A (Mac).

Template margins

All templates have a 3mm margin on all sides, as this is the non printable area of the printer.

Template Print Info

Some template have info labels activated (see Template Editor). These are shown as an orange box. With the Print Info Popup menu you can determine which information will be printed; None will leave the info label clear, Filename allows you to print the filename. This will always be in black, left aligned. Date allows you to print the current date, Custom allows you to enter your own text in the textbox below the PopupMenu.


To help you position pictures exactly, for instance to meet passport photo requirements, Titan supports guidelines in an identical way as Gemini 4 did but now integrated into one single application (basically EPP Layout as you may know it from Gemini 4 is built into Titan). Guidelines (and ellipses) can be edited in the Template Editor.



Edge Line

You can have the edge of all Cells printed with a colored edge line if you check the box Edge Line. The Popup Menu to the right allows you to set the line thickness in pixels. By clicking on the black box to the right of the line thickness Popup Menu, you can choose any color.

Cutmarks Popup

There are three options for cut marks when using templates. No Cutmarks obviously does not print any cut marks. The second option is Page Edge. Then the template page size will be indicated using inside corner cutmarks. The third option is Cells only. In this case all cells will be printed with cutmarks.

For cut sheets you would usually not use cutmarks on Page Edge as these will correspond with your paper size. For roll printing, or printing templates on larger cut sheets than your template, the Page Edge cutmarks are usually used. Cell only cutmarks can be handy when you need to cut the individual cells, especially when the image has a white background.

The lenth of the cutmarks can be selected using the Popup Menu to the right of the CutMarks Popup Menu.

Borderless templates

You can print borderless templates by checking the Borderless checkbox. This will instantly change the Template preview, so you can see how much of the image will be cropped of. The amount or borderless expansion can be set in the Preferences Tab.  6 mm is usually adequate and will retain most of your image. Setting the borderless expansion to a value lower than 6 is possible, but at your own risk: if you get white lines at the edges these cannot be claimed as mis-clicks. If you miss a paper size on which you want to print borderless, add it using the template editor and add a cell at the very top left of the template. You can enter 9999 as width and height to make the cell as large as possible on the template. Checking the Borderless checkbox will then expand the image to the edges of the paper.

Cell Mode

Cells can show the image in two different ways; Fit or Fill. Fit will scale down the image (in proportion) to fit the cell. Fill will expand the image (if needed) to fill the entire cell. You may lose some of the image in Fill mode, but can fully control the crop and rotation of the image using the Scale & Rotation Sliders, after selecting the cell you wish to modify. The crop can be defined by either setting the horizontal and vertical sliders below and to the right of the Cell Mode box, or by clicking and then dragging the image in the cell. Scaling is limited to 300% to avoid resolution deterioration. Rotation can be set to any value ranging from -90 to 90 degrees. If you need more rotation, uncheck autorotate and manually rotate the image using the rotate left or rotate right buttons before setting the rotation angle. Please not that rotation angles might decrease image sharpness, and can cause white corners to appear if the scaling and crop are not properly setup.

Guidelines checkbox

When you check this box, the guidelines will be projected over a dropped picture, allowing you to position it. Guidelines are never printed and are intended to help you position your pictures accurately.

Cell Letters

Templates with single letter cells (A) will modify all cells. On templates with multiple letter cells (A, B, etc), each letter can be modified individually.

Auto Rotate

When Auto Rotate is checked (default) the images you drop on a template will be rotated to best fit the cells. This means that a portrait picture will be rotated if dropped onto a landscape cell. You can override this by unchecking the Auto Rotate box, and then use the Rotate Left or Right buttons after clicking the cell you wish to modify. When Auto Rotate is active, the Rotate Left & Right have no effect. To set a rotation other than 90 degrees, use the Rotation slider.


In the Pages section you can set the number of copies needed. When you drop multiple images on a template, template pages will be added if required. The size of a template page is shown in mm. The Add and Delete buttons allow you to Add or Delete a template page. When there are more than one Pages, the Scroll bar below Add and Delete allows you to select each Page. To the right of the Scroll bar the currently selected and number of pages are shown.

Printing a Template

When you are ready to print your template pages, click the Print button. Please note that if the light to the right of the print button is not green, this means you may have to change settings on the server before you can print this job. If the light is red, this means the job cannot be printed due to the current printer and media selection: make sure the size of the paper allows the selected template to fit.


Free Layout Tab

The Free Layout tab allows you to print images on any size, even with canvas edges or with a custom passepartout.  In Free Layout you can only work with one file at the time. If you need to process a large batch of images, use the Template Tab as Templates allow you to drag multiple files. You can select multiple files by clicking on one file first, and then shift click on the last file you want to select. All selected files will then turn blue. These files can then be dragged to a cell on the Template Tab, and they will all be processed. If you prefer to drag images from a window, you can do that to. Both Template and Freelayout allow you to to drag and drop from external windows.



You can rotate the image by 90 degrees by clicking on the Rotate button. Please note that the Gemini12 server will rotate the image to save media if possible, unless this has been switched of on the server.

Image size

To set the width and height dimensions simply enter the wanted width or height. The resolution will change when you change the dimensions. By default, images maintain aspect ratio. If you want to crop part of the image, use the Crop checkbox.


Images can be cropped using the crop checkmark.

The easiest way to set a crop is to first enter the needed width and height, and then use the mouse to drag the selection to the desired position. This allows you to select an exact size from an image that has a different size. This allows you to make a print that exactly fits a frame for instance. The red/black box shows the cropped print. Please note you can combine a Crop action with an Edge action. For selection purposes, the edge is not as it will print but shows the entire image. When you print a cropped image with an Edge, it is first cropped, and then the defined edge is added.


There are three different Edges selections possible. By default, no edge is added (None). The other two options are Equal and Custom.

Equal Edges can be used in two different ways:Mirror and Color. To add an equal edge of white or a selected color to all sides of the print, you select Color and choose a color by clicking on the black box to the right of Color (if you want a non white edge).
The Mirror option will mirror the image to the edges, allowing for canvas prints to be made.

Custom Edges can be used to create a passepartout, to make the print fit a frame:

You can define the Top, Left & Right and Bottom edge separately. If you want the edge to be coloured, you can check the color and click on the black box to select an edge color. On Mac you can also pick a color from the image using the pipet in the color selector.


In preferences, you have the option to add a (PNG) logo to the print. This logo will be place in the image itself unless you select the Edge option in Preferences. (See Logo settings in Preferences).

Output settings

In the output section at the lower right, you can see the actual output dimensions. There you can also set the number of copies for a print. Please note that this value is reset to 1 after printing to avoid unwanted extra copies on the next print.

Cut Marks can be added to allow easy cutting of image with a white edge. The length of the cutmarks can be set in mm.

Cut CheckBox can be checked to make the printer cut the print after printing is finished.


Nesting is possible by checking the Nest checkbox. This will make the server try fit your different prints more economical, by rotation and changing the order of the jobs in the active queue on the server. Nesting is a great way to avoid having to make a template each time you wish to combine two or more prints on a selected paper size. Please note that if you do not select Nest when you print, all jobs will be printed individually, unless the queue on the server is not started by default. If the queue is not started, you can select the jobs you wish to nest in the server view, and create a nested job from these jobs to save media.

Wall Art Tab

The Wall Art Tab allows you to visualize a print before it is printed on any wall of any room. You can select any of the predefined rooms or add your own.

You can use FreeLayout selected images or art selected in Art On Demand to visualise them before printing. By default, the print will be shown in the default dimensions. By using the slider you can increase the size of the print, which is then shown in the larger size on the room wall. You can select any of the supplied rooms, or add your own (our your customer’s) wall pictures, so you can show how a print would look on a customer’s wall before printing.

Adjusting scale offers the ability to show the print in the correct scale. For this you click on the left side of an item close to the wall of which you know the dimensions.  Then you drag the mouse to the right edge of that item and release the mouse. This allows you to enter the dimensions of the item you just selected. In the example above, the seating area of 180 cm was chosen and entered as 180. This updates the scale and makes the print match the room scale. This way you can show how large (or small) a print would look. This feature enables you to sell larger prints, as customers often have little idea on how large a print will be even if you mention the dimensions. By visualising, anyone can understand how large the print will be.

It is possible to save the picture of the room with the projected print, so you can print or email it to a customer.


Template Editor Tab

The Template Editor allows you to edit existing templates or add your own. Unlike Gemini 4, Titan has the Template editor build into the same client application, making it easier to use.

The List on the left hand side shows the available templates. You can filter this list by using the filter popup menu. This makes it easier to find the wanted template. Once you select a template, a larger version will be shown on the right. The name and page size will be shown at the top. The Memo Field allows you to enter a memo text for reference. When you add the text “Pass” to the memo field and save it, it will also show up when choosing the Passport filter, so you can add additional passport templates to the 25 built in Passport templates.

Templates (from Gemini 4 or other Gemini 12 users) can be imported using the import button.

Adding a new Template

To Add a new template, enter a name in the template textfield, selecting a paper size and then click on new, which will create the template with the chosen name and page dimensions. By Clicking Save you will save the changes made or newly defined template.

Adding cells

Image cells can be added to a template by clicking on the New button in the light grey area above the larger preview. If you do not define a position and width or height, a cell will be placed at the top left (3 , 3 ) and have a width of 50 x 50 mm. You can change the size of a cell by selecting it, and entering new dimensions. Dimensions are automatically limited to the page edge, so if you enter a high value such as 9999, it will be limited to the maximum size possible on the selected paper.

Changing cells

The position of image cells can be changed by selecting the cell and then dragging it using the mouse. For more exact positioning, you can also enter the exact position from the top left corner, and enter the exact width and height. Use the arrow keys on your keyboard to move a selected cell by 1 mm. Use Shift+Arrow keys on your keyboard to move a selected cell by 1 cm.

Cell groups 

By default, cells have group A. A group defines if they should contain the same image or a new image when images are dropped onto the template in the template tab. By changing the letter, you can define different images on the same page. When you define multiple cells with the same letter, they will show the same image when used in the templates tab. You can define up to 150 cells on a page, and use as many image letters as you like.

Info Box

A new cell be default has no Print info box. You can set a Print info box by checking the Show Print Info checkbox. This will create a green box just below the cell. If you want to position it elsewhere, carefully click the green box and use the arrow keys to reposition.

Duplicating Cells

If you need more identical Cells, use the Duplicate button to create a copy, which will be offset by 5 mm to the right and down.


To add multiple cells at once (to create a table of cells) you can use the Matrix button. First define the position and dimension of the top left cell by entering the values. Then choose how many Rows and Columns of this cell you would like, and enter the spacing in-between the cells. When you then click new, Columns x Rows cells will be added at position x,y, all with the width and height entered and with a spacing as defined.

Aligning cells

To align a cell to the edge or corner of a page, select the cell and click on any of the Align boxes. This will snap the selected cell to that position.

When you are done editing a template, click on Save to store it. After saving, Templates can immediately be used in the Templates Tab.

Guide Lines

Guide lines can help you position an image to meet requirements, like passport photo’s.
By double-clicking a cell, you open up the guide line editor. It has two tabs: One for straight lines and one for Ellipses. Up to 12 Straight lines can be defined, 6 horizontal and 6 vertical. Their position can be defined from Center, Top, Bottom, Left or Right.
Only when set active they will be shown.


In Addition to straight lines, one Ellipse can be defined also.

For an ellipse you define 4 points, also possible from Top, Center, Bottom, Left or Right. Only when you check the show Ellipse checkbox they will be shown on the template. In a future update, we will include a full set of templates that meet passport pictures for different countries. By using these, it is easier to meet the sometimes very strict photo requirements for documents.

Art On Demand Tab

Art On Demand allows you to print & distribute Art in a controlled way. It is possible to host your own Art library for on-line printing, in a secure way. This means the images are stored in the cloud encoded, only accessible by placing an order. Only the publisher has access to the original files. This ensures no prints are made and high resolution files do not need to be distributed to print production locations. Instead, when an AOD order is placed, the image is streamed from the cloud straight into the linked Art On Demand printer. Not even the printer has acces to the file in any other way, and the print can only be made once.
To learn more about the Art On Demand options, contact Gemini Systems.

In preferences, user credentials have to be entered to gain access to AOD libraries. The Art on Demand Tab then allows searching the art library, either by using a search reference (like Paris in the above example) or by selecting a Category, Artist or Orientation. When Search is clicked, thumbnails and all information is shown in a scrollable list.

To order a print from an AOD library, you click on the image, which shows a larger preview and then offers a submit button:

Clicking the Submit button will take you to the Wall Art tab, so you start to visualise the Art on the customer’s wall (See Wall Art Section)

In the Wall Art tab, when submitting an Art On Demand print, the Art On Demand section allows you to choose a paper type and if needed a mirrored or coloured edge. Once you click on Place AOD Order, you will be given a Certificate of Authentication in PDF, which can be printed for the customer. Meanwhile, within 2 minutes, the ordered Artwork will be waiting in the Server queue, ready to be printed.

Preferences Tab

The Preferences tab contains settings that affect the other tabs in Titan.

Reference Print

When Gemini 12 is installed, a reference print is made on the installed printed, and measured, to verify that the printer is performing accurately in terms of printing quality and color accuracy. The Customer’s name and a comment line can be added to Reference print, which is A5 size, so two be printed on a single A4 sheet.

Titan automatically adds the selected Printer, Media, ICC profile and Entered Customer and Extra comment info before printing the image. This reference print should be made when a customer suspects the printer is not performing optimal anymore. (After having verified the nozzle print is ok). The reference image contains a strip that can be measured by Gemini Staff that will give a Pass or Fail result for verification.

Borderless Enlargement

Although the default setting should work perfectly, it is possible to override the enlargement by entering a custom value that will be applied with borderless template print jobs. Please note that white lines due to entering custom values is not accepted as a mis-click, so use with caution.

Canvas Length Adjustment

When printing large prints on thick media like Canvas, especially when they exceed the paper width of a roll printer, the length of some printers is not 100% accurate, resulting in prints printing shorter. To compensate this hardware issue, Titan offers a unique feature that will compensate for this hardware issue. You can enter a correction percentage value, so that the print matches the wanted dimensions. To obtain the correct percentage, you measure the requested print height and divide that by the actual print height, and multiply that by 100. Enter the exact number, so with an actual print of 1460 mm instead of the requested 1500 mm, you enter 102.739726, which will make the actual print match the requested dimensions. Please note this feature only works for media types that contain “canvas” in their name.

Water Mark

Titan allows you to add a watermark to all cells on a template and on Free Layout. When you check the Print checkbox, the watermark text you enter will be shown on any cell in Template and Freelayout. They are printed diagonally at the opaqness set in Preferences. 100 means fully visible, 0 is completely transparent.


Logo’s can be added to prints for advertising or event photography. When you check the Print checkbox, the logo will be printed. The Image button allows you to select a PNG logo file. PNG was chosen so you can add a logo with transparency. The size at which it will be printed can be entered as a percentage of the image width. The position can be indicated by clicking any of the nine Postion radio buttons. For Canvas prints, you can have the logo printed on the edge instead of in the image, so it will be visible on the back of the framed canvas. To do so, check the Edge option. Any chosen logo will be shown in preview.


When printing, Titan checks if the resolution of the images meet the minimum value entered and warns if that value is not met.
100 dpi is an acceptable resolution for large prints, you can increase this value to set a higher minimum accepted resolution.
Rendering is performed on Template Jobs, as they can contain many images with different resolutions. 360 is optimal for Epson, for Canon and HP you can change this value to 300. The highest quality is maintained when a value is chosen that is a division of the printer resolution (which is max 1440 on Epson and 1200 on Canon/HP) so a value of 359 does not work as well as 360 on Epson, and 360 does not work as well on HP or Canon.

Remote Print

Gemini 12 offers two methods of Remote Printing: Gemini Remote Printing and Peer to Peer Remote Printing.

Gemini Remote Printing

Even when you do not have a Gemini12 server or when you want to print larger than the printers you have can support, you can submit print jobs for printing at Gemini Systems, using the Gemini Remote Printing Printer Queue. This queue is available in the Printer Popup menu and works exactly as a local printer, without the option to control it yourself, as it is located at Gemini Systems.

When you print Gemini Remote, before submitting your print, you will get a popup message where you can enter any addition comments, like a delivery address or some production instructions. You have to enter your own email address before submitting a Gemini Remote Print, as email will be used for notifications to both the sender and Gemini Systems. Please note that Gemini Remote prints have a starting costs for handling and shipping.

Peer to Peer Remote Printing

The second way Gemini offers Remote printing is called Peer to Peer printing. This means that any user can print to another (published) Gemini12 printer from anywhere in the world, using the internet as a network. To enable users to print to your local printers, you click the Publish button. This brings up a windows where you can define the published printers:

To publish a printer, check the active button and enter a maximum width for each of the printer/media combinations you wish to publish. For extra safety, you can enter a pin code that the user needs to enter to access your published printers. After publishing, you can inform the remote user about your ID and Pin Code (if applicable)

The Remote user can enter the ID provided by the publisher, enter the Pin Code and click on Connect. Any available remote printers will then be added to the printer popupmenu.  Remote Peer to Peer printers are exactly like remote ones, with the only difference being how data gets from Titan to Gemini12: A remote print uploads the print job into the cloud and notifies the publisher by email. To print a remote Job, the Publisher clicks on the link in the email generated by the remote print, and selected that job for printing once downloaded using the Print button in Preferences.


Art On Demand

Please contact Gemini Systems if you want to publish your own Art, or would like access to a library hosted by a Gemini12 AOD publisher like IG (International Graphics*) (*available only in selected countries and after approval by Gemini Systems)

Enter the User name and Password and click login to get access to a specific publisher. Once logged in, you will see any available Publishers. Select the one you want to choose Art from and proceed to the Art On Demand Tab.

The Show Pricing option allows prices to be displayed, based on the square meter price entered. This allows quick price calculation.

By default, Art On Demand thumbnails are stored on your desktop. You can choose a different location if required.

Printed by, Print date and Logo offers the ability to add this information to the certificate of authenticity. The Logo file should be PNG and supports transparency.






Titan is color aware, meaning that it has a built in color engine, based on icc profiles. When no profile is embedded, sRGB is assumed. On templates, the first image placed determines the icc profile. All subsequent images are converted to that icc profile before print.

Printing Progress

When you click Print, TItan goes through a number of steps, that are indicated by both a progress bar and a text label.

The steps involved are: opening the high resolution file, creating the job file, size and color conversion (if needed), Job ticket and thumbnail creation, compression (lossless LZW in most cases) and copying the file to the server.

In template mode, the preview flips through the number of pages in the template.

Error prevention

In order to try prevent printing problems, Titan monitors your job’s dimension and warns if they exceed the loaded media. Titan also warns if you try to print an image at a very low resolution (as set in Preferences). The color indicator next to the print button indicates possible problems; green means everything is ready to go, orange means there might be problems, red means you cannot print yet. A red light is usually caused by not selecting a printer and paper. An orange light can be caused by the dimension or resolution.
