Nitto Denko Corporation has developed the DURAINK 10PN dedicated thermal transfer ink ribbon and DURATAK label ink for high resolution, high performance thermal transfer printers used for labels for electronic equipment and labels for manufacturing control.
By using special olefin resin for thermal transfer ink and the base material, this product enables clear printing of small characters, high-density bar codes and 2-dimensionsal bar codes. The ink of printed labels can also stand up to being wiped with organic solvents and detergents. It is also able to withstand rubbing.
It is the ideal label for electronic equipment beginning with IT related equipment.
Labels for electronic equipment are now primarily printed on demand at the site. The printers use thermal transfer type resin ink. Printing with conventional thermal transfer printers involves the following problems:
It was impossible to solve all of these problems with the existing label materials. While the more compact the electronic device itself gets, the less space there is for applying a label, the amount of information that needs to be printed on the label is increasing. This increased the need to develop a heat transfer label capable of satisfying requirements for higher resolution ink that can withstand chemicals and friction.

Using the same material for the base material and the ink (olefin resin) makes the ink thermally fuse with the label. Further optimizing the clearness and coagulation of the ink realizes high-resolution printing that had been impossible with conventional thermal transfer methods. As a result a large quantity of information can now be printed in a limited space.
(For example a symbol of 2-dimensional code of 39 alphanumeric characters used to require 4.5 x 4.5 mm of space, whereas with this product a minimum of 3 x 3mm is required.)
Making the ink thermally fuse with the label base material has dramatically enhanced printing durability.
Optimal design of label base material and ink enables printing that uses less energy than printing with conventional plastic labels and resin ink. This enables high-speed printing by most thermal transfer printers. (Seal printing is also possible.)
Antistatic layer eliminates the problems of unprinted portions due to dust on the label surface and difficulty with handling due to electrostatic charge when peeling
