If your design firm asks you for "high res" artwork, they are seeking a 300 dpi (dots per inch) or greater image at its desired final size. Anything less is called "low res" artwork.

A 300 dpi photo, for example, can be proportionally enlarged for lower resolution output; however, a low resolution photo can't be enlarged without obvious reductions in image quality. Below are some common resolution standards.

"Low Res"

• 72 dpi: Screens and Monitors
• 96-120 dpi: Flat Panel Monitors
• 150 dpi: PowerPoint Slides, Mobile Phone Graphics, Trade Show Graphics, Billboards

"High-Res"

• 300 dpi: Digital and Offset Press
