To avoid having to scrap large quantities of substrate with a poor print due to insufficient bonding it is always advisable to check Corona treated material before printing. Using a felt tipped Dyne test pen is an easy and inexpensive way to check if a substrate is ready for printing.

How to measure the surface tension using Dyne pens
The test itself is carried out quickly and easily by simply drawing a line of test ink across the substrate. Whether the film has a higher or lower Dyne value than the test ink is determined within the first 3 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 indicate if the correct areas were treated.
Vetaphone’s Dyne test markers are supplied in Dyne value range from 32-56 dyne/cm (32-56 Nm/m) in steps of 2 Dyne. They are delivered complete with user instructions, and are sold singly or in sets of 8 pens with Dyne values of your own choice.
