Guide: generate a 600 DPI QR code PNG
600 DPI can help when a print workflow requires high-resolution raster output instead of SVG.
Create 600 DPI PNGSteps
Confirm raster requirement
If the software accepts SVG, vector may be simpler.
Set 600 DPI
DPI must match the intended physical dimensions.
Keep modules crisp
Avoid resampling that blurs module edges.
Keep contrast
Use black modules on white by default.
Test final output
Scan after layout placement and after printing.
