Compression and Artifacts:

• DPI (Dots Per Inch): An image downloaded from an HD site must be at least 300 DPI to print clearly on standard paper.
• Dimension Scaling: A 1920x1080 pixel image is physically small when printed at high quality (roughly 6.4 x 3.6 inches). For a high-quality poster, the source image must be significantly larger (often 4000px+ on the shortest side).
