How to Fix Unavailable Color Separations in Acrobat Print Settings
Question details
The user is unable to select color separations when attempting to print a full-color newspaper center spread from Acrobat Pro to an imagesetter.

- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Printing a full-color newspaper center spread to an imagesetter for prepress production.
- Observed behavior
- The Separations option in the Advanced Print settings dialog is unavailable or grayed out.
Ensure that your imagesetter is powered on, properly connected to your network or workstation, and that you have the administrative rights to modify printer driver settings.
Verify PostScript Workflow and Printer Support
Ensure the selected output device and driver fully support color separations and PostScript workflows, as incompatible drivers will disable this feature.
Acrobat relies heavily on the printer driver's capabilities to determine which output options are available. If a non-PostScript driver is selected, prepress features like separations are hidden.
Open the Print dialog in Acrobat Pro (Ctrl+P or Cmd+P) and ensure your specific imagesetter or PostScript RIP is selected from the Printer dropdown menu.
Click on the 'Advanced' button at the top of the Print dialog box to access the professional Output settings.
Under the Output pane on the left, check the 'Color' dropdown menu. Ensure 'Separations' can be selected instead of 'Composite'.
Close the Advanced dialog and ensure that poster-printing mode or scaling features are turned off in the Page Sizing & Handling section, as these can conflict with separations.

Update Imagesetter Drivers and Acrobat Software
Outdated RIP (Raster Image Processor) software or Adobe Acrobat versions can cause compatibility issues with modern prepress workflows.
Use WPS PDF for Seamless Document Printing
While specialized imagesetter workflows require dedicated prepress tools, WPS Office provides a powerful, built-in PDF editor for standard high-quality printing, document formatting, and page management.
- 1. Open Your PDF: Launch WPS Office and open your PDF document using the WPS PDF viewer.
- 2. Access Print Settings: Click on the 'Menu' icon in the top-left corner and select 'Print', or use the Ctrl+P shortcut to open the print dialog.
- 3. Configure Layout: Adjust the page sizing, orientation, and layout options for your specific print job.
- 4. Send to Printer: Select your target printer from the dropdown list and click 'Print' to generate your output.

Frequently Asked Questions
Why is the Separations option grayed out in Acrobat Pro?
The Separations option is usually disabled if the selected printer does not support PostScript, if you are not using a compatible RIP driver, or if conflicting print settings like poster-printing are currently enabled in the print dialog.
What is a PostScript workflow in PDF printing?
A PostScript workflow utilizes the PostScript page description language to accurately translate complex layouts, fonts, and colors from a digital PDF file into high-quality printed output, which is strictly required for generating color separations.
Can I print color separations to a non-PostScript printer?
No, standard non-PostScript inkjet or laser printers process composite colors (CMYK or RGB mixed together) and cannot natively generate the individual cyan, magenta, yellow, and black plates required for physical prepress color separations.
How do I verify my document's color settings before printing?
In Acrobat Pro, you can use the Output Preview tool found under Print Production. This allows you to check the color spaces, verify spot colors, and simulate how the separations will appear before sending the file to the imagesetter.
