Dyne pens
Kolding Denmark
Using a felt-tipped dyne test pen, it is easy and inexpensive to check if a substrate is ready for printing, according to Vetaphone. The test itself is carried out by drawing a line of blue test ink across the substrate with the pen. Whether the film has a higher or lower dyne value than the test ink is determined within the first three seconds after application as the line of ink either remains stable or reticulates (breaks up into droplets). On a partially treated substrate the test ink can also be used to control if the correct areas were treated.
