Gayatri G founded Permanent QR Codes to solve a specific problem: QR codes printed on products, packaging and equipment outlive the software subscriptions behind them. Her work focuses on keeping those printed codes readable and routable for the life of the object they are printed on.
Her guides are written for the people who put codes into production: packaging engineers, prepress teams, plant and maintenance managers, and procurement teams buying codes at volume. Product defaults and print guidance on this site are checked against the ISO/IEC 18004 QR code specification.
Areas of focus
- Physical print longevity
- Why printed codes fail, how redirects, domains and subscriptions affect lifespan, and how to keep a code working after the campaign ends.
- Packaging engineering
- Codes on cartons, labels and retail displays: scanning distance, curved and glossy surfaces, data density and the move to 2D barcodes at checkout.
- Vector specifications
- Print-ready SVG and EPS files, module size, quiet zones and error correction levels for prepress.
- Hardware and manufacturing
- Engraved and etched equipment tags that link to manuals, safety data sheets and service records for the life of a machine.
