Minimum Dimension Scaling: Matching X-Dimension to Printer DPI
Barcode quality starts with sizing that the printer can actually reproduce. If the selected X-dimension resolves into awkward fractional dots or anti-aliased scaling, the printed mark will drift from the intended geometry.
| Printer DPI | Common starting point |
|---|---|
| 203 | 10-12 mil for many linear labels |
| 300 | 7-10 mil when substrate and scanner allow |
| 600 | Fine-detail work with careful validation |
Use integer-dot thinking where possible and validate the physical result instead of trusting CSS scaling.
