Pre-Press Tool

Thermal DPI Calibration Check

Before you commit a print run, verify your GS1 2D code survives the press. We compute the X-dimension and printer dots per module for your target label size and DPI, and flag codes that will smear into an unscannable block at the port.

Longer payloads pack in more modules — denser codes need more size or DPI.

Your pre-press verdict will appear here.
Thresholds: a GS1 2D symbol should print at least 15 mm wide with at least 4 printer dots per module.
