Application Note: Simulated Long Term Storage Condition Block Test for Ink Transfer and Film Adhesion Properties on a Flexographic Printed Film – Part 1
22 April 2016

The ink blocking test evaluates the adhesive properties of inks on the substrate. In this application note describes the use of a Specac hydraulic press and heated platens with automatic temperature controller which enables simulation of life time storage conditions to be carried out on printed film. The flexographic printing process is commonly used for film printing because it is quick and relative cheap in terms of design changeover.
