Adjust Accessibility and Color Display Preferences in Acrobat
High contrast or custom accessibility color settings in Adobe Acrobat can override document colors, causing black text to look gray.
Adobe Acrobat includes accessibility settings designed to make documents easier to read for visually impaired users. Sometimes, these settings are accidentally triggered to replace document colors, resulting in black text appearing gray or washed out.
Launch Adobe Acrobat. Navigate to Edit > Preferences on Windows, or Acrobat > Preferences on a Mac.
Select 'Accessibility' from the categories on the left-hand side.
Look for the 'Replace Document Colors' checkbox. If it is checked, uncheck it to ensure the document displays its original intended colors, then click 'OK'.
If the text still looks gray, return to Preferences, select 'Page Display', and uncheck 'Smooth Text'. Anti-aliasing can sometimes make thin black fonts appear gray on low-resolution monitors.
Verify Text Transparency and Overprint Settings
Design settings applied during the PDF creation process might render black text with unintended opacity.

Frequently Asked Questions
Why does my black text look gray when printing a PDF?
This often happens due to color conversion settings in the print dialog. Ensure 'Print as Image' is unchecked, or check your printer's grayscale and color management settings to ensure it is using true black ink.
Does anti-aliasing make black text look gray on screen?
Yes, 'Smooth Text' or anti-aliasing features in PDF viewers blend the edges of text with the background color to make it look smooth. On thin fonts or low-resolution screens, this blending can give black text a washed-out, gray appearance.
How do I check if the original text color in the PDF is actually black?
You can use the 'Edit PDF' tool in a PDF editor to highlight the text and view its font properties. The color picker will show the exact Hex or RGB value of the text, confirming if it is set to pure black (#000000) or a dark gray.
