Assorted example labels
5 labels measured against Labelary on every test run
Hand-picked examples committed with the renderer: Labelary's own sample, a UPS label, a USPS Ground Advantage label, a carton label and a GS1 DGR label.
The suite renders every label below on each test run, and compares the output with Labelary's for the same input. The status states what matters for a label: the layout is the same and every barcode carries the same data. The percentage is the share of pixels that differ — rendering detail such as font rasterization — and it does not set the status.
Summary
| Status | Labels |
|---|---|
| Pass — the layout and the barcode data match | 4 |
| Known defect — the output differs in what it says | 0 |
| No committed comparison | 1 |
| In the corpus | 5 |
The widest difference in the corpus is 3.36%, on USPS ground advantage testing label. One label has no committed comparison: GS1 DGR complete.
A label with a content or blocking known issue reads known defect, whatever it measures. Every other label reads pass: the layout and the barcode data match. A cosmetic issue names a visible rendering difference without changing what the label says.

Known issues
1 of the 5 labels carries an annotated defect, 1 defect in all. The severity comes from the label, not from the percentage:
blockingmeans content a reader misses;contentmeans the output differs in what it says;cosmeticmeans it differs only in how it looks.
Cosmetic defects
- USPS ground advantage testing label, 3.36% — At 3.36% this is a measured limit and not an open defect. Per tile alignment now removes only 18% of it as a one or two dot shift, the block-placement fixes having taken the rest. What is left is outline shape and rasterizer fringe, and every field is present and reads the same. Closing this band needs new outlines or another rasterizer.. Owned by
