Pressure-sensitive adhesive sheet for mobile electronics

Provided is a PSA sheet capable of bringing about good air release properties in mobile electronic applications. The present invention provides a PSA sheet for mobile electronics. The PSA sheet comprises a substrate film and a PSA layer provided to at least one face of the substrate film. The PSA layer has a thickness of 20 m or less. The PSA sheet further comprises a coating layer that partially covers the PSA layer surface. The coating layer has a thickness less than 3 m.

Printing plate connection systems

Techniques are disclosed for connecting a printing plate to a print cylinder or surface. The techniques may be implemented, for instance, with respect to a printing plate, a print cylinder, a print sleeve, or some combination thereof. In an embodiment, a field of mechanical fasteners is provisioned on a printing plate, and a complementary field of mechanical fasteners is provisioned on a print sleeve or cylinder. The mechanical fasteners collectively operate to provide a mechanical bond or interface that inhibits lateral and rotational movement of the plate during printing operations, and can also be configured to manage backlash between engaging surfaces of the interface. In some cases, backlash management includes use of cushion effect integral with the mechanical bond itself and/or unidirectional and possibly angled fastener elements to provide a snugging effect. The mechanical bond may be implemented with hook-and-loop, hook-and-hook, hook-to-channel, male/female-type fittings, vacuum, suction, and/or magnetics.
