Introduction: Before you Begin
If you didn’t separate your colors into layers while you made the piece, you have a few options:
- Option 1: Separate out the colors using the Menu > Select > Color Range (try a few different tolerances) and make spot channels with that.
- Option 2: Convert the whole image to Grayscale, and re-color the whole image using the multi-channel color space.
- Option 3: Simulate a four-color process print (CMYK) by using the channels as they are.
Adjust your document setup by checking the following:
- Check your image size
- The maximum printable area is 10” x 16″.
- This allows room for crop and registration marks.
- Set your resolution to 600 dpi
- Menu Bar > Image > Image Size > Resolution: 600
- Set your color space to Adobe RGB (1998)
- Menu Bar > Edit > Convert to Profile > Destination Space: Adobe RGB (1998)

- If you prefer to add the Riso colors manually, be sure to add them as SPOT PANTONE colors
- Save your document as a new file.
- Note: these methods all require switching your color mode and deleting channels, which can be a destructive workflow (e.g., layers get flattened or color information is discarded). When working with channels, it is difficult to revert back to the previous look. It is best to keep your final piece, with all its layers and edits, as a separate file.
