QR codes on signs, stickers and packaging
A sign on a wall, a sticker on equipment or a code on a box can outlive any subscription. Check it before the print run, not after customers say it doesn’t open.

What to check before printing
- Where the code goes: the address stored in it and the final page after the redirects.
- Whether it goes through a QR service or a link shortener.
- Whether the final page answers. If it doesn’t, QRInspect shows a stop sign and the reason.
Codes that last outdoors
Choose high damage resistance. The code still reads when part of it is scratched or dirty; the pattern gets denser, so print it a little larger.
A dark code on a light background reads best. Test red ink, glossy film and clear labels with a proof first. For large formats use the SVG file: it stays sharp at any size.
Many codes at once
Asset tags, room signs and product packaging often need one code per item. Paste a table of addresses and labels, or fill it with sequential numbers. A paid plan downloads the batch as SVG, vector PDF and PNG with a print sheet.
For product and warehouse labels, QRInspect also makes 74 barcode and 2D code types, such as EAN-13, Code 128 and Data Matrix, and the checker reads 43 of them.
Questions
How big should a QR code on a sign be?
It depends on how far away people stand. A common rule of thumb is about 1 inch of code width for every 10 inches of scanning distance. Print a test and scan it from where people will actually be.
Can I change where a printed sign points?
Not with a static code. Point it at a page you control and change what that page shows.
Is a static code safe from going dead?
It doesn’t depend on us or any other middleman. It keeps working as long as the page it points to is online.
