zpl-toolchain sample labels
6 labels measured against Labelary on every test run
The sample labels published with zpl-toolchain: a GS1 compliance label, a retail product label, a generic shipping label, a USPS SurePost sample and a warehouse location placard. Synthetic throughout — no recipient data. The corpus is published here.
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 | 6 |
| Known defect — the output differs in what it says | 0 |
| In the corpus | 6 |
The widest difference in the corpus is 3.10%, on USPS SurePost sample — MaxiCode, Data Matrix and ^FV field variables.
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 defects first, then the widest rendering difference.
