Color contrast checker for print legibility

WCAG AA requires a contrast ratio of at least 4.5:1 for normal-sized body text and 3:1 for large text above 18 points. For most printed materials including flyers, brochures, and postcards ordered through Cheap RUSH Printing, AA compliance is the right target to ensure legibility for the widest audience. AAA compliance at 7:1 is worth pursuing for small captions or fine print where readability is especially critical.

Gradients do not have a single contrast ratio because their color changes across the element. To check a gradient effectively, sample the lightest and darkest hex values from the range where text will appear and test each one separately. The color contrast checker gives you the ratio for any pair of hex values, so testing multiple points across the gradient ensures text remains readable everywhere it overlaps in your print design.

Yes, printed color always differs from what you see on screen because ink on paper absorbs light rather than emitting it. Glossy coatings can boost apparent contrast while uncoated stocks tend to look slightly flatter. Use the RGB to CMYK preview alongside the color contrast checker to simulate how your hex color pairs will behave on press before ordering flyers, postcards, or brochures through Cheap RUSH Printing.

Yes, the color contrast checker lets you download a score summary that includes the tested hex values, contrast ratio, and WCAG pass or fail status. Attach this document to your prepress checklist for sign-off before submitting files to Cheap RUSH Printing. Sharing scores with clients or internal stakeholders during the review stage prevents contrast problems from being discovered after the print run is already complete.
