Will it print sharp?
How it works
Ten seconds now saves a ruined blank later.
01
Add your image
Drop the file in and we read its pixel size automatically (it never leaves your device), or type the dimensions, or tap a common source like “phone photo”.
02
Set the print size
Type the physical size it will print at, or tap a blank preset (tumbler wrap, mug panel, shirt front) and we fill in the verified dimensions.
03
Read the verdict
Effective DPI, a sharp-to-blurry gauge, the maximum clean print size for your image, and a warning if the shape doesn't match the print area.
Resolution FAQ
DPI, demystified for sublimation.
300 DPI at the final print size is the standard for sharp sublimation prints. 200–300 DPI still looks good at normal viewing distance; 150–200 is only acceptable for large pieces viewed from afar; below 150 DPI prints visibly blurry and pixelated.
Verdicts use the 300 DPI print standard. Fabric and textured blanks are slightly more forgiving than hard glossy surfaces, but no substrate can rescue an image below 150 DPI. Images dropped here are read entirely in your browser and never uploaded.
