摘要:
Disclosed are various embodiments for generating classifications for items from normalized item attributes. Multiple attribute options are maintained for an item. Each of the attribute options is associated with a respective range of values on a normalized scale for an attribute. Multiple item classifications are generated for one of the attribute options by mapping the respective range of values for the one of the attribute options to one or more item classifications on each of multiple scales of classification for the attribute.

A multilayer compensator includes one or more polymeric first layers and one or more polymeric second layers. The first layers comprise a polymer having an out-of-plane birefringence between −0.005 and +0.005. The second layers comprise an amorphous polymer having an out-of-plane birefringence that is either less than −0.005 or greater than +0.005. The overall in-plane retardation of the multilayer compensator is greater than 20 nm, and the out-of-plane retardation is more negative than −20 nm or more positive than +20 nm. The amorphous polymer of the second layer(s) has a glass transition temperature (Tg) such that 110° C.≦Tg≦180° C. when the Rth of the multilayer compensator is more negative than −20 nm, and 100° C.≦Tg≦160° C. when the Rth of the multilayer compensator is more positive than +20 nm.
摘要:
A negative-working imaging member can be used as a lithographic printing plate without ablation. The imaging member comprises a support and an imaging layer that includes a dispersion of at least 0.05 g/m2 of a cyanoacrylate polymer that is thermally degradable below 200° C., a photothermal conversion material that is present in an amount to provide a dry weight ratio to the cyanoacrylate polymer of from about 0.02:1 to about 0.8:1, and a hydrophilic binder to provide a dry weight ratio of a hydrophilic binder to the cyanoacrylate polymer of up to 1:1. Thermal imaging energy causes the exposed areas of the imaging layer to adhere to the support while unexposed areas can be readily washed off and/or simultaneously inked for press runs.
摘要:
A lithographic imaging member, such as a printing plate, has a support having thereon an ink-accepting melanophilic layer and an ink-rejecting siloxane surface melanophobic layer. Within the printing plate is a photothermal conversion material capable of converting irradiation, such as IR radiation, to heat in exposed regions. Also within one of the layers is a compound that upon imaging releases a moiety that facilitates degradation of the surface melanophobic layer. The released moiety can be fluoride ion or a fluoride ion-containing compound. In some imaging members, a barrier layer may be interposed between the two other layers. Such imaging members can be digitally imaged and used for printing without post-imaging processing.
