Compression Artifact A compression artifact is a distortion or visual anomaly that occurs in digital images or video as a result of data compression techniques used to reduce file size. Common compression artifacts include blocky pixelation, blurring, ringing, or color banding, which can degrade image quality and reduce detail and clarity. In Giclée printing, avoiding compression artifacts is important when preparing digital images for printing to ensure that printed output retains high-quality, crisp detail, and accurate color reproduction. |
