Evaluation of Available ISO 13655 Backing Materials and Measurement Differences for the Packaging Industry
Jinkai Qian, Techkon USA
The Annex A of ISO (International Standard Organization) 13655 defines sample backing materials used for the graphic arts industry. Due to the versatile aspects of print processes, different vendors and print manufacturers are using various backing substrates for color calibration or measurements.
This study has two parts: 1) Evaluate backing products available on the market based on the ISO requirements. 2) For all compliant backer substrates, a simple opacity comparison test using 0/45-degree geometry spectrophotometer on multiple film samples will be conducted to see the variation when using ISO compliant backers.
The goal of this research is to find out the feasible backer solutions for print suppliers and brand owners as well as to understand common tolerance when various ISO backers are used when discussing print quality control requirements.
