printcolormanager

Version: 1.0 Date: 2026-05-23

The printcolormanager package provides an automated and unified color management workflow for LaTeX documents. It allows users to easily prepare the same document for different output media, such as CMYK for professional printing, RGB for screen viewing, or grayscale for black-and-white printing, simply by changing a single package option.

Key features:

• Global package options to switch the target color model (CMYK, RGB, gray, etc.).
• A unified macro (definePrintColor) to define exact, manual values for custom colors across all color spaces.
• Built-in prepress protections, including predefined "Pure Black" for typography and "Rich Black" for large background areas.
• Automatic adaptation of xcolor and TikZ elements to the selected output.

The following command can be used to inspect the embedded images contained in the final PDF:

pdfimages -list peldadokumentum.pdf

This command prints a table listing the images found in the PDF. The output includes several useful properties, such as the page number, image type, dimensions, resolution, compression method, and color space. The color column is especially important, because it shows whether an embedded image uses, for example, rgb, gray, or cmyk color space.

This check is useful for detecting images that remain in RGB in a print-oriented CMYK workflow. However, pdfimages mainly examines the raster images embedded in the PDF; it does not provide a complete analysis of vector graphics, text objects, or every color-related element generated by LaTeX. Therefore, it is particularly useful for verifying embedded bitmap images.

Supported Options:
