Proof a "pull back" trap

  1. Select Rich Black.p1.pdf and make a Loose Page VPS proof to view the trap results.
  2. Open the loose page VPS output.
  3. Using the zoom tool, enlarge the bottom of the yellow $ (dollar sign) and some of the reverse type.
  4. Turn off all colors except Black and Spot Yellow.
  5. Confirm that Spot Yellow traps to Black by moving the black slider to the left. You will see the overlap between the colors.
  6. Turn off Spot Yellow and turn on Cyan. In this image, cyan is used as a "booster" color to enhance the black background.
  7. Move the black slider to the left. View the zone around the white type that has no cyan appearing in it.
    This is called "pull back", and is designed to prevent cyan from showing in the white type if there is misregistration on press.
  8. Turn off the Black separation, and turn on the Spot Yellow separation.
  9. Move the sliders for either the cyan or the spot yellow colors. You will not see any overlap between these colors as black is trapping these areas.
  10. Quit the Virtual Proofing System software.
  11. Close XX_Rich_Black_Trap Job Manager.
