Use this procedure to reduce spot colors in impositions proofs—for example, when pages have spot colors that will be plated but are difficult to proof.

CAUTION: If the spot colors will never be plated, reduce them during refine whenever possible. Color conversion is more predictable during refine than during other processes.

  1. Switch to the Signatures view, and select the surfaces or signatures that you want to proof.
  2. Reduce individual spot colors using the Color Separations dialog box:
    1. From the Edit menu, select Color Separations.
      The Color Separations dialog box appears.
    2. Select the spot color, and then select an option in the Output Selected As list:


      ToSelect This

      Convert a spot color to process color

      Either Convert to Process or a process color

      Map a spot color to another color

      A spot or process color

      (If the color doesn't already exist, first add a color separation.)

      Preserve a spot color


      (The separation is output separately only if the Do Separations check box is selected in the Render section of the process template.)

      Omit a color from the proof

      Do Not Output
    3. Click OK.
  3. Start an imposition output process on the selected surfaces or signatures by dragging the surfaces or signatures to the imposition output process template.
  4. Preserve any other spot colors by setting an option in the process template:
    1. In the Start Process dialog box, click Edit Process Template.
    2. Expand the Render section.
    3. In the Output Separation Handling list, select Output all separately.
    4. Close the process template.
  5. Click OK to close the Start Process dialog box.

    The proof process occurs, applying the settings of both the Imposition Output process template and the Color Separations dialog box. The proof is generated.

  • The Color Separations dialog box does not work with PDF files that are composite. Also, with vector files, you can do spot-to-spot mapping, but you cannot omit spot colors or convert them to process color.
  • Changes made in the Color Separations dialog box affect all future imposition output and final output.
  • You can also use the Color Separations dialog box to print separations. Select the spot color, and select Separately in the Output Selected As list.
  • You can modify and save the process template before you start. Start the process using the modified process template, and do not click Edit Process Template in the Start Process dialog box.
