Photoshop

Prepare an image with spot channels for printing from another application

  1. If the image is a duotone, convert it to Multichannel color mode.
  2. Save the image in DCS 2.0 format.
  3. In the DCS 2.0 Format dialog box, deselect the Include Halftone Screen and the Include Transfer Function options.
  4. Open or import the image in Photoshop, and set your screen angles. Make sure that you’ve communicated to the printer the spot color you want for each of the color plates.
    Note: You can place a PSD file containing spot colors directly in Illustrator or InDesign without special preparation.
