You have a CMYK separation with a white base color for dark textiles.

Every channel must be reticulated before printing or reticulated in a rip printer.

The channels you are showing are just grayscaled separeated inks, where we see the amount of ink we must use in every silkscreen.

enter image description hereIt seems to be a separation for silkscreen, like a DCS EPS. In silkscreen, the white is another color, the base, imagine printing on a black t-shirt (the ctrl+7 channel). The other four are the process colors for the illustration. Will be interesting to see a picture with RGB channels hidden, to see the illustration colors.

This image is an old EPS DCS i have for silkscreen with three inks. If you change the color of the channel for the correspondent ink, you will see the illustration. The order of the channels must be like in the printing process, on my case lighter colors on the bottom.

  • I don't understand how they get Ctrl+7, 8, 9... channels? – Jelena Petrovic May 3 '18 at 16:32

    it seems they duplicate CMYK channels to a RGB file and add ctrl+7 channel with the image border. Is the easy way. On my illustration i separate every part as a different layer and use posterization. – Danielillo May 3 '18 at 16:52
  • I understand your file but I don't understand why I have RGB channels and down Ctrl+7, 8, 9... channels (2-305-Process yellow). I am confused a little bit with that :) – Jelena Petrovic May 3 '18 at 16:55

    I guess you can delete RGB channels. May be they keep them because if you delete them, after there are no possibilities for saving as JPG to send the file. They file will become a Multichannel file and EPS DSC is the format to save it, but the file gets bigger. – Danielillo May 3 '18 at 16:58
  • Thanks a lot. I think I understand better this :) – Jelena Petrovic May 3 '18 at 17:03
