How to Identify Card Printing Errors
Printing errors on trading cards include print lines, color shifts, dot patterns, roller marks, and ink spots. Print lines are thin colored lines visible on the card surface and are the most common defect in modern cards. Color shifts cause the image to appear slightly off-registration. Roller marks create repeating patterns across the surface. These errors typically lower a card grade unless they are dramatic enough to be considered collectible misprints. AI tools can help detect subtle printing issues.
