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).
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!
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
Many digital devices can now print with ECG inks. For example, HP Indigo uses Orange, Green and Violet inks 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)
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!
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!
