It will work on concrete ❗

That is, exactly the printing of the production label on concrete pits.😉
Some photos of the tests with our client today. 👇👇👇

You can print a long label in a row in one "stroke" - see. image #4 and the long tag photographed below.
Or you can split the label, for example, into 3 parts and print them one after the other - see photo #3.
Otherwise, thanks to the smooth surface, both barcodes and QR codes (in which the customer will put a link to a video manual, etc.) can be read perfectly.
🔝 solution for us.

Printer used: B35
Cartridge: EB21B - water based (can be refilled 🙂)
Print density: 8/10
