ASTM F2452-04(2012)

4.1 Good adhesion is a prime consideration for print media. For coated papers failure can occur between the coating and the substrate or between coated layers, while for uncoated papers failure can occur between the imaged area and the substrate. This practice utilizing mechanical stress allows comparative studies of print media by examining adhesion in both printed and unprinted areas.

4.2 Factors in the office and outdoor environments, such as heat, cold, thermal shock, ultraviolet/visible radiation and water vapor can have a similar effect on adhesion as mechanical stress.

4.3 This practice is used to obtain comparative data of adhesion strength of print media.
