- Scenario
- Preparing a PDF document for professional print production and needing to ensure accurate CMYK color output.

Use the Output Preview Tool in Acrobat Pro
This is the standard and most accurate method for inspecting CMYK separations and exact color values within a professional PDF workflow.
The Output Preview tool provides a precise simulation of how your document's colors will look when printed. It allows you to isolate individual CMYK channels and check the exact percentage of cyan, magenta, yellow, and black at any point on your page.
Launch Adobe Acrobat Pro and open the PDF document you want to inspect.
Click on 'All tools' from the main menu, scroll down to the 'Protect & standardize' or professional category, and select 'Use print production'.
In the Print Production panel, click on 'Output preview'. Ensure the 'Show' dropdown is set to 'All' or a specific color space.
Check the box for 'Separations' in the dialog window. Move your mouse pointer over different text or image elements in the document; the dialog will display the exact CMYK percentage values for the pixels under your cursor.

While specialized print production tools like CMYK previews require an Adobe Acrobat Pro subscription, WPS Office provides a free, fast, and feature-rich alternative for all your general document and PDF needs.

Frequently Asked Questions
Can I check CMYK values using the free Adobe Acrobat Reader?
No, the Output Preview tool is a premium feature. It is only included in the paid Adobe Acrobat Pro version under the Print Production toolset.
Why are my PDF colors displaying in RGB instead of CMYK?
The PDF may have been exported from the source application using an RGB color profile. To fix this, you can use Acrobat Pro's 'Convert Colors' tool inside the Print Production menu to convert the document's color space to a specific CMYK profile.
Can the Output Preview tool detect spot colors like Pantone?
Yes, if your document contains spot colors, they will be listed individually below the standard CMYK process colors in the Output Preview dialog window.
