M2345 Posted February 12, 2023 Posted February 12, 2023 Hello, I want to take an image and separate the color channels into three different downloadable files, each file being on of the color channels (exemple, one file with the image with the green channel, one with the blue and one with the red). It doesn't seem to work but I really need it to print the image with a risograph. Thank you in advance for your help. Quote
Hangman Posted February 12, 2023 Posted February 12, 2023 @M2345, welcome to the forums... I can't claim to know a great deal about Risographic prints but my assumption (rightly or wrongly) is that you need the individual RGB channels output as greyscale files, is that right? If so there are several methods but perhaps the quickest and easiest is using the Procedural Texture Live filter as shown here... If this isn't what you need can you elaborate a little further...

M2345 Posted February 12, 2023 Author Posted February 12, 2023 Oh thank you I will try it but it does seem to be that ! Quote
David in Яuislip Posted February 12, 2023 Posted February 12, 2023 This macro will produce three greyscale layers named red, green & blue. You can then use the Export persona to export to files.
