Product Information

Development of label ink for high resolution, high performance thermal transfer printers Ideal for labels for electronic equipment

Industrial Products Division, Tape-Material Business Sector

10.7.2002

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.

Background of product development

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:

  1. Characters become illegible if a lot of information is printed in a small area.
  2. Ink cannot withstand organic solvents, detergents and rubbing.

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.

Product Structure

Product Characteristics

1)  Enables high resolution printing that was unavailable up to now

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.)

2)  Ink is not washed off by organic solvents and detergents, and it is able to withstand rubbing.

Making the ink thermally fuse with the label base material has dramatically enhanced printing durability.

  • Unlike conventional thermal transfer printer inks, our ink is not washed away or smeared by organic solvent s or detergents containing ketone.
  • Realizes durability far superior to that of combination of conventional plastic labels and resin ink.

3)  Enables high-speed printing by general purpose thermal transfer printers.

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.)

4)  Minimizes static electricity and electrostatic charge.

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
