Selecting ribbon/material
Label material
When selecting the material, you must take 3 factors into account:
– the abrasive behavior of the surface structure of the material;
– the properties with regard to the chemical reaction when printing ink is
transferred;
– the temperature required to transfer the ink.
Abrasive
behavior
If the material is very abrasive, the print head becomes “worn down” quicker
than would normally be the case. This criterion is of particular importance in
thermoprinting. It is not so critical in the case of thermotransfer printing, as
the ribbon can be chosen to be somewhat wider than the material, ensuring
that the print head is protected across the entire width of the material.
Head
temperature
The same applies if the temperature of the print head is high. Material and
ribbon need longer to cool down, the print quality is more critical and the print
head will wear down sooner.
For papers with grammages greater than 240 g, it may be necessary to make
adjustments with regard to the contact pressure and the position of the print
head.
Thermotransfer ribbon
For ribbon, we recommend the following:
– the reverse side of the ribbon must have an antistatic, friction-reducing
coating (backcoating);
– ribbons must be specified for “near edge type print heads”;
– ribbons should be suitable for print speeds of up to 12 inch/sec.
(300 mm/s).
Ribbon without these properties can reduce the performance of the
printer and/or the print quality as well as damage the print head!
