QR code on T-shirt: how to design it for scanning

The QR code for clothing must also work outside the monitor. Check contrast, margin, print site, target address and tests before the series is performed.

The QR code on the T-shirt can lead to a portfolio, event pages or product collection. Just generating a square isn't enough. The project needs to be checked on material that moves, frowns and puts on the silhouette.

Start with the address to remain current

First, determine the purpose of the scan. The site should work on the phone and immediately show the promised content. If the code is to lead to the order, do not direct the user to the general page from which he must long seek the product.

It is worth considering a short address in your own domain, which you can manage. The external generator or shortener may have its own operating conditions. Check them before printing, especially when the service advertises the code as "dynamic." You can't change the pattern without re-tagging the shirt.

Keep free space around the code

QR needs a clear margin separating it from other elements. According to DENSO WAVE documentation for the standard QR code, this zone shall have a width of at least four modules on each side. The module is a single small code building field.

Geometric example: The 29 modules side matrix together with such a margin takes 37 modules. If the module had 1 mm in a given project, the whole area would be 37 mm. This is just an example of calculation, not a guaranteed minimum print size on each shirt.

Do not place the inscription or frame in the required margin. A decorative illustration should begin outside of it.

A simple contrast is a safe starting point

The dark code in the uniform clear field gives a clear reference point to the tests. Multicolor gradients, background texture and intentional abrasions hinder performance assessment. If you want to use the color of the brand, check first contrast graphics on clothing and scanning in practice.

Don't add a logo in the middle just because the generator allows it. Each interference changes the reading conditions. More important than decorativeity is whether the user gets to the right address quickly. Compare the decorative version with the simple one, keeping the same size.

Select a place that doesn't bend the code

Side suture, castle, pocket or strong wrinkling fragment are not a good place for a square requiring recognition. When printing on your back, think of the distance from which the recipient will try to scan. A little sign at the neck doesn't have to be comfortable in the crowd.

Under the code you can add a short clue, e.g. "See Collection" and a clear address as an alternative. But don't cover the margin with this. Marking technique should maintain the regularity of fields; detailed code in embroidery requires special care and evaluation of performance.

Test the file and the finished product

Scan export, then paper preview on the target scale, and with an important series also sample on your clothes. Check various phones, normal lighting, and slight fold of material. Control not only the reading, but also the exact address, the correct opening of the page and the lack of misdirections.

To be asked about DTF printing attach vector or good quality raster code, target link, dimension and location. In the series for the event, schedule the time for the test; the test on the screen does not confirm the operation of the finished clothing.

THE MOST COMMON QUESTIONS

FAQ

What minimum size should the QR code be on your shirt?

There's no one value for all the codes. The number of modules, margin, contrast, technique, material, and scanning distance count. The dimension needs to be checked on the target product.

Can you change the address after printing the code?

Only if the address used or redirected remains under your control or this is provided by the chosen service. The conditions must be established before production.

Can QR code be part of a larger illustration?

Yes, provided that the margin is clear and free. The final project needs to be tested, not based solely on the preview of the generator.
