Custom printing

NFC Tags are white.

Black printing (1-2 days) is done with the thermal transfer technique. It is a low quality print, but very resistant and economical. It is normally used for serials, barcodes or QR codes. However, simple logos can also be printed.

Offset printing (5-8 weeks) is carried out with the Offset technique, during the label production process. It offers the best print quality ever. The file for printing must be in CMYK, possibly vector.
