The color reproduction when printing from a notebook, e.g., “Print Selection” of a Graphics, is terrible. For example, Yellow is printed as Magenta. See the attached notebook for illustration.
ChatGPT (GPT-5) says:
Wolfram Language renders graphics and color styles in the front-end color space (RGB), but when printing or exporting to PDF, the system internally converts to a PostScript color space, which sometimes uses CMYK or DeviceColor. This results in:
- Color channels being swapped (e.g., yellow → magenta),
- Transparencies being mixed incorrectly,
- Or halftone colors (e.g., GrayLevel, RGBColor) being converted to incorrect device profiles.
This is particularly noticeable with colors with a high red or yellow component.
ChatGPT then provides a series of cumbersome workarounds designed to prevent the ColorSpace from changing. None of them are practical. The easiest solution is to go to File > Printer Settings > Printing Environment and change the setting from “Printout” to “Working”. However, this means that nothing will be printed anymore when you select some cell(s) and use "Print Selection".
I consider this change in color space during printing to be a Wolfram error. Does anyone have a practical solution?
