Module size vs nozzle diameter
Measure how progressively smaller QR modules reproduce across nozzle sizes while keeping the payload and overall test method controlled.
MODUQR LAB
A testing framework for physical QR performance
The Lab is where we will separate measured print results from generic advice. No fabricated benchmarks: experiments will be published only after the test method, printer settings and observed results are documented.
Research status
The structure is available, but it will stay out of the public index until original measurements are published.

Planned test protocols
Raised vs Recessed physical scan test
Compare equivalent QR matrices in Raised and Recessed geometry under the same size, material and scanning conditions.
Material and contrast test
Test practical color/material combinations and scan distance without assuming that digital contrast alone predicts the physical result.
Why the Lab exists
Digital QR validation can confirm that the generated matrix decodes correctly, but a printed object introduces nozzle width, layer height, material, surface finish, lighting and camera distance. The Lab is intended to measure those physical variables rather than pretending a browser can guarantee them.
What a published experiment should include
A useful Lab result should identify the QR payload or density, physical module size, nozzle diameter, layer height, material, geometry mode, print orientation, scan device and test distance. Results should distinguish observed behavior from recommendations.
Why this page remains noindex for now
The Lab structure is ready, but original experiment data has not been published yet. Keeping the hub out of the production index until real measurements exist avoids creating a thin page that implies evidence we do not have.
