Unfortunately, PDFs are sometimes reproduced incorrectly. For example, graphics with white areas in my PDF have a yellow background (e.g. around logos). Inserted white areas are rendered yellowish in the PDF. But some fonts are also reproduced in a different colour.
I have already googled several times and implemented measures for similar problems. Adjustments in the settings for "accessibility" or in the colour management of the laptop. Unfortunately all without success.
and croll down to the section "Color-managing PDFs for printing (Acrobat Pro)" and see the first few paragraphs that suggest using PDF/X‑3 standard:
QUOTE from link above: "(PDF/X‑3) Does not convert colors. Use this method when creating a document that is printed or displayed on various or unknown devices. When you select a PDF/X‑3 standard, color profiles are automatically embedded in the PDF."
