Low-resolution images look fine on screen but pixelate in print. Printery's DPI checker catches every low-res image before you export — saving you from expensive reprints.

DPI (Dots Per Inch) measures how many ink dots fit in one inch of printed output. Higher DPI means more detail and sharper images.
Screens display at 72-96 PPI, but commercial printing requires 300 DPI for crisp, professional results. Using screen-resolution images in print results in visible pixelation.
Printery scans every raster image in your selected frames, calculating the effective DPI at the current print size.
Images below your target DPI (default 300) are highlighted with warnings showing their actual resolution.
Replace low-res images with higher-resolution versions, or resize them smaller to increase effective DPI.
| Print Size | Min. Image Size (300 DPI) | Common Use |

| 24" × 36" | 7200 × 10800 px | Large Poster |
Formula: Print size (inches) × DPI = Required pixel dimensions
