Your PDF background might appear pink because it's likely using the CMYK color format instead of RGB. Here's a more detailed explanation:
Why CMYK Can Cause Pink Displays
- Color Modes: Digital displays use RGB (Red, Green, Blue) to create colors, while printing often uses CMYK (Cyan, Magenta, Yellow, Black).
- Compatibility Issues: When a PDF designed with CMYK color profiles is viewed on a screen (which uses RGB), the colors might not be interpreted correctly, leading to unexpected color distortions.
- Pink Hue: Often, this misinterpretation shows up as a pink or purplish tint, especially when the document contains a lot of cyan (a color used in CMYK, not RGB), as this color may be improperly rendered on an RGB display.
How to Fix a Pink PDF Background
According to InVision support documentation, the solution is to:
- Re-export the PDF: Use your PDF editor or design software to re-export the PDF using the RGB color format.
- Replace the Old PDF: Upload the newly exported RGB version to replace the existing one.
Comparison Table: CMYK vs. RGB
| Feature | CMYK | RGB |
|---|---|---|
| Use Case | Primarily for printing | Primarily for digital displays |
| Color Basis | Cyan, Magenta, Yellow, Black | Red, Green, Blue |
| Display Result | Might appear incorrect | Displays correctly |
By re-exporting your PDF to RGB, you'll ensure it displays correctly on screens and eliminate the pink background issue.
