➤Touch7 is NOT a profiling or colour management solution provider – There are already excellent systems out there to do press characterisation.
➤ It is assumed that a printer would already have their press fingerprinted to create a multichannel profile, in which case they would convert Touch7 images to that profile. If the customer does not use spot colour printing to date, they must have their press characterised using existing technologies, which would take in to account the spot inks being utilised on the press. This profile would also be loaded up in to the Touch7 Soft-Proofing tool – This will then show an image/design with the correct press profile, based on the customers ink set.

I keep getting a “Max Activation” message when trying to load Touch7
- Touch7 is licensed as a single seat application. If you attempt to install the Touch7 plug-in on another computer, using the same license code, you will get the message that you have reached the maximum activations per your license code. Please note that license codes can have multiple installs, if your license purchased is a multi-user license code.
Why have the Touch7 Photo buttons stopped working, when I have a valid license?
- If you have a valid Touch7 license and you notice that the buttons on the plugin suddenly stop working, it’s highly probable that you have tried to go back in your Photoshop History to the original image, in order to try out some other Touch7 buttons! However, when Touch7 does it’s calculations, it creates “Snapshots” based on it’s working process – If you try to go back in your History, those “Snapshots” will still be present and as such, it will lock out the other ECG buttons. To resolve this, simply delete the existing “Snapshots” from your history. To see how this is done, please check out our video tutorial page, with the video called “Deleting History Snapshots”
Minium system requirements
- Touch7 requires Adobe CC or higher.
Touch7 is a cloud based subscription service, and as such requires the user to have an Adobe Creative Cloud account. If you do not have a creative cloud license, Touch7 will not work.
Touch7 works with both Mac and PC
Will Touch7 work with Adobe CS6 or earlier?
- NO. Touch7 requires an Adobe Creative Cloud account. It will not work in earlier versions.
Do I need to use special ICC profiles to convert my images using Touch7?
- NO. Touch7 does not create ECG separations through ICC profiles. Instead, Touch7 intelligently calculates the ECG ink separations from the source pixels. The final converted image using the Touch7 extended colour gamut plugin, retains your original file format, with the addition your chosen ECG spot colours.
Note: Once an image has been converted using Touch7, a user may then choose to convert the Touch7 image to their preferred in-house multicolour profile (Edit/Convert to Profile – setting within Photoshop).
Why do I need Touch7? Can’t I just use a n-color ICC profile in the RIP?
- A question was posed to our technical team "Why do I need Touch7? Can’t I just use a n-color ICC profile in the RIP (as an output profile) and keep my images in the original wide gamut RGB (with profile) all the way to the RIPing process?"
Doing Extended Colour Gamut working in the RIP, you have no creative control over the image.
Question to consider – If you have a ripped job, let's say it's a page out of a clothing catalogue – can a profile choose to only apply ECG to one image on that layout, ignoring all the other images? Or does a profile apply it's effects to ripped data (1bit tiffs) used to print/proof?
A profile does not allow you the creative freedom to isolate individual colour groups and/or selective areas. It's all or nothing with a profile. How would a profile apply enhancements to just one area of one particular image? For example. You have a CMYK image of a lady in a red dress, holding a bunch of purple flowers, standing on pale green grass, against a dark blue sky...All of which could be enhanced for ECG...But I only want to boost the ladies red dress, and I don't want it to effect my skin tones. How would a profile handle that?
Also, having and RGB workflow is great...If you have an RGB image! And even if you do have an RGB image, who's to say it's not already been converted to CMYK at some stage, clipping the colour data, and then saved back to RGB? Or that it’s actually a good quality image with good tonal range and saturation? What’s more, given that the printing industry has just spent the last 20+ years telling designers NOT to work in RGB as it would not match the CMYK proofs they would get in return...We have a long way to go to get them all using RGB again!
Touch7 gives creative freedom to the designers who do the work. Think about this – if you design a file in CMYK and run an Epson proof out and send it to your client to approve (the client signs off your Epson for colour and content) – you then send that file to a printer, who in turn converts it to an extended gamut – The printer charges you/the designer for the proofing (more cost) and it goes back to the client to sign off…but it will no longer match the original proof the designer sent the client to approve in the first place! Not to mention if the designer makes changes to the artwork, or asks the printer for colour correction to the ECG enhanced areas.... Back and forth with proofing, whilst costs stack up! So, why do the work at the end of the work flow? Why not do it upfront, where the creativeness happens and save both TIME and MONEY?
Everyone is thinking about profiles, nobody is thinking about the designer or creativity! And those that do think of profiles, are typically the high end printer that can afford complex and expensive separation systems.
Whilst we need process control and profiles, there's a missing market and tools for the creatives. As ECG printing becomes more mainstream, how does a designer design for ECG? I recently asked Pantone® how a designer is supposed to separate their artwork for their Pantone EG swatch book within programs such as Adobe Illustrator – their response? They couldn't tell me! Their proprietary solution is to use their "spot" EG colors and then send that file to a high end print shop who has purchased the Esko Eclipse system to do the separations, taking all control away from a designer, pushing the page price up and lengthening the time to market! Our solution? Watch this video... www.touch7.co/vector/how
And what about getting creative with ECG – you only need to look at the background of the “Camera Shy” Calendar below. Notice the pattern in the background that has been knocked out of the ECG gradient? – how would a profile do that? You can't! You can only do creative stuff, at the creative stage!
Why are Touch7 ECG spot colours different to other ECG inks?
- Touch7 does not use profiles to extract out ECG data and therefore does not need to know what inks you use on press or what hue value they are. Touch7 extracts ECG data from the source image based on pixels and light. It should also be noted that the spot plates that Touch7 creates are just greyscale separations - when you assign a colour to those separations/channels within Photoshop, that greyscale plate takes on the colour appearance of that spot colour. So, what you see on the screen is literally just a screen visual - when you print those separations on press, you would map the spot colours to your own tried and tested ECG inks or to the ECG inks on your digital device.
The reason we chose the spot colours names/values for Touch7
You will find that the spot colours in a Touch7 image are different to the spot colours others companies may use, either on digital or offset. For example, Pantone® has specific colours that they want people to use for their XG guide – Pantone® needs an ECG ink set that can match the broadest range of their own spot/brand colours from their colour books. However, with Touch7 we are not matching any Pantone® spot colours, so we can use colours that will provide the best printed image! For example, you could convert an image using Touch7 to generate an ECG image, and you could print that on a digital device using only CMYK (the spot colours would be mapped/processed back to CMYK using the closest match to the LAB values of the Touch7 spot colours). If you set your colour values to the green used by Pantone®, when you print that image on a digital device using only CMYK, it will take the values of that colour specified in Photoshop - in this instance, a blue looking green. If you look at an RGB spectrum, green is green, not blue/green!
If you look at the colour splits below, Touch7 ECG colours are on top, Pantone® (also FIRST for flexo) are on the bottom. Pantone® uses a very deep orange, which we personally find makes images go towards the red end of the spectrum – if you put that amount of orange under an already orange colour, it shifts more towards a red/orange end of the spectrum. Using the orange values we have specified, when printed in CMYK only, provides a much cleaner orange/red gamut of colours. The same for the greens etc.
• Touch7 images use spot colours that IF PRINTED IN CMYK would give a better colour as those spot colours are mapped to the closest CMYK percentages.
• If Touch7 images are printing on a device with ECG inks, then the spot colours within Touch7 should be mapped to the ECG inks on press.
• Touch7 does not require profiles to extract out EC colour data, therefor we don't need to know the hue value of the inks on press
Do I have to use RGB images or can Touch7 work with CMYK?
- NO. Touch7 will work with any coloured image, however the best conversions are achieved from an original image captured in RGB. Images that have been converted to CMYK have already had some of their colour data clipped – For more information on converting CMYK images, please review our training videos
Why do my images not look any different when printing directly from Adobe Photoshop?
- If you are trying to print a Touch7 image in RGB plus spot colors directly to your device from within Photoshop, it will not be possible as they are two entirely different color spaces, RGB being additive and spot colors being subtractive. Photoshop cannot directly process/render the two opposing color spaces within one image. You will need to import your image in to a page layout program such as Adobe Illustrator or InDesign, and output from there.
DIGITAL, INKJET AND TONER FAQs
Can Touch7 be used with Digital, Inkjet or Toner printing devices?
- DIGITAL & INKJET PRESSES
Many digital devices can now print with ECG and/or Neon Fluorescent inks. For example, HP Indigo uses Orange, Green and Violet inks and also has a fluorescent pink, to print in an extended colour gamut. Touch7 can be used to generate image separations for most digital printing devices capable of printing in an ECG gamut. For digital devices, you can also print just using CMYK (no ECG inks) and still have an increased image saturation (see next FAQ regarding CMYK printing)
Touch7 Neon will work with toner systems that have Neon Fluorescent inks or toners. For example, Ricoh Pro C7100 series press uses Neon Yellow and Neon Pink toners.
And, for traditional ECG printing (Orange green violet etc) – provided that you are using a workflow that is capable of simulating spot colours, Touch7 can be used to enhance your images, without having to use ECG inks! With toner based devices, a master ECG image is generated, which would normally be printed using CMYK plus up to 3 spot colours. However, most toner printing devices do not have spot toners, so images are processed back in to CMYK at the RIP, with the ECG spot colours being matched as close as possible to LAB values of the Touch7 separations. You can now achieve higher saturated images, taking your toner device to a new level of colour!
Can Touch7 be used with CMYK printing devices?
- Yes. Digital, inkjet and toner devices use inks/toners with a vastly superior gamut and transparency to traditional process inks used on analogue devices, so it is possible to increase the gamut of your images WITHOUT actually having to print with ECG inks!
ECG spot colours can be effectively matched using sophisticated algorithms in the raster image processor (RIP). An example of such technology would be EFI’s Fiery Spot-On™, Heidelberg’s PDFToolbox or HP’s SmartStream Production Pro Spot Color Refinement tool, all of which can emulate spot colours within a file and processes them to their closest match out of CMYK. Whilst a remapping of the spot colours to CMYK on these devices will not be a 100% match to spot colour printing, it is impressive how much improvement such a workflow can make to your imagery!
PRINTING & INK FAQs
What are the recommended inks and ink densities for analogue printing?
- ECG inks vary across printing devices, with some machine manufacturers developing their own proprietary ECG ink sets. As such, you should use the ink for your particular device. However, as a guideline, the following inks can be used for analogue devices. Note: The ink you use on press does not effect the physical separation within Photoshop – Our default ECG colour names can easily be mapped to the ink used on the press/printer, via the RIP.
Recommended Pantone® Inks
Pantone® Bright Red
Recommended Ink Density (Status-T, paper inclusive)
1.85 +/- 0.10
1.50 +/- 0.10
1.60 +/- 0.10
1.85 +/- 0.10
1.60 +/- 0.10
Recommended CMYK Ink Density (Status-T, paper inclusive)
1.30 +/- 0.10
1.35 +/- 0.10
1.60 +/- 0.10
1.00 +/- 0.10
What are the LAB values for the Touch7 ECG inks?
Recommended LAB Values for printing
L*70 A*47 B* 79
L*63 A*-73 B* 36
L*33 A*18 B* -68
L*58 A*72 B* 62
L*19 A*55 B* -70IMPORTANT: The LAB values for Touch7 have been chosen to provide the best printed image when using a CMYK only workflow on a digital, inkjet or toner devices. It is these LAB values that you would need to assign at the RIP for each Touch7 ECG colour.
What are the LAB values for the Touch7 NEON inks?
Recommended LAB Values for printing
L*55 A*-38 B* -43
L*61 A*76 B* -16
L*93 A*-19 B* 69
Printing with AM screen angles
- We typically recommend FM screening to ensure absolutely no screen clash, but, if you only have AM screening the basic rule is to use the screen angle of the least prominent screened process colour that will be underneath the screened spot colour. As a general rule, we would recommend the following:
Red/Orange or NeonPink touch plates. Output separation on same angle as Cyan
Green or NeonYellow touch plates. Output separation on same angle as Magenta
Blue/Violet or NeonBlue touch plates. Output separation on same angle as Black
Will Touch7 Photo, work with the new PANTONE® Extended Gamut Guide?
- YES. Touch7 Photo can work seamlessly with the new PANTONE® Extended Gamut Guide, just as it will work seamlessly with other spot colour separation technologies. Simply process your images as usual, and if required, edit the Touch7 ECG spot colour names to match the PANTONE® Extended Gamut Guide naming nomenclature, or map the Touch7 ECG spot colour names at the RIP, to the destination ink set used on press.
