For inkjet label printers
Inkjet label printers work with a so-called back feed. This means that the labels are pulled back when printing starts. This happens not only during the first print, but also after interim maintenance of the printhead.
In addition to the backfeed that has to be compensated, there is one more important difference with thermal printers. An inkjet printer does not like if the labels are pulled or if there is (too much) resistance when entering the labels.
An inkjet printer can therefore only function properly with a modified rewinder and unwinder. The adjusted unwinders should ensure a constant and low tension at the input. An unwinder for an inkjet printer must therefore only be able to unwind but also to be able to rewind.
The rewinders come in several variants. The winding does not always have to be able to go back and forth, sometimes enough space can be created by means of a loop to receive the back feed without tension.
For a standard solution, the modified variants of Godex such as the Godex T10C can be used.
For simple roll to roll printing, a complete set of the DPR-SRL rewinder, unwinder and baseplate is recommended. This allows for easy alignment of the printer with the un- and rewinder.
There are 2 options for printing labels with the Epson TM-C7500 (G). The simplest and most logical choice is the original Epson rewinder. This is mechanically connected to the printer so that it works together as 1 machine. The special Z-CAT rewinder from Labelmate is available for applications where label rolls need to be tightly wound.
