Touch7 Photo ECG™ is a Photoshop plug-in that uses proprietary separation technology to automatically isolate and extract out extended colour gamut colours from your images – and all at the touch of a button!
Increasing the printable colour gamut enables a wider range of colours to be achieved by adding custom inks to a standard CMYK ink set. Whilst extended colour gamut (ECG) printing has been around for many years, it is often out of reach to many printers due to the high investment cost of purchasing a dedicated colour separation system.

Unlike other ECG systems that employ the use of a destination/press profiles to separate images, the
Touch7 Photo ECG plugin works intelligently at the pixel level, automatically isolating and separating the desired touch plates for extended colour gamut printing. The end conversion adds up to three additional spot colours to the users original image format – For example, if you have an RGB image and convert using Touch7, you will end up with your RGB image plus up to three spot colours. Note: Touch7 Photo ECG does not require ICC profiles to extract ECG separations – our proprietary separation algorithms calculate the effect based on the original source information.

The image below was processed using one of the
Touch7 master presets, with no image masking required. Notice how only colour groups that can benefit from an ECG ink set are targeted by the Touch7 Photo ECG algorithms – All other colour groups, such as yellows, magentas and light cyans, are excluded, ensuring ECG inks only effect those colours true to an extended colour gamut.

Colour coded “One Click” Buttons

Single colour touch plates –
Generate ONE additional touch plate to boost an individual colour group

Two colour touch plates –
Generate TWO additional touch plates E.G. Red & Blue

Three colour touch plates
– Generate THREE additional touch plates E.G. Orange, Green & Violet

(Source Image Colour Removal) – Removes the equivalent ECG colour hue from your source image.

With Touch7 Photo ECG, you can generate extended colour gamut images for printing up to seven colours. For example, you may have an image whereby you only want to boost the Orange and Green colours, leaving the blues untouched – in this instance, you would use one of the “TWO COLOUR” touch plate buttons.
With Touch7 there are two possible workflows for printing with ECG formatted designs. A traditional ECG workflow requires the printing of up to seven colours, however, an alternative to printing a true ECG workflow, would be to convert images using Touch7 to generate a CMYK design, plus up to three ECG spot colours, but when that file is processed at the RIP, the ECG separations would be processed back to CMYK along with the source image, to generate a composite CMYK file – This workflow however, can only be used with digital, inkjet or toner devices, as those devices use pigments with a vastly wider gamut to traditional printing inks. 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 designs!
