A printable blank sheet includes a sheet with a first layer and a second layer attached to a bottom side of the first layer, slit-over-perforation line in the sheet, and an object held in the sheet. The slit-over-perforation lines define a periphery of the object in the sheet. The slit-over-perforation lines include cuts running through the first layer, and perforations running through the second layer underneath the cuts running through the first layer. A method for creating custom print objects includes running a printable blank sheet through a printer, wherein the sheet includes slit-over-perforation lines defining a periphery of an object in the sheet. The sheet is bent along the slit-over-perforation lines to weaken and separate the slit-over-perforation lines, and the object is detached from the sheet.

An overcoat layer for an organic photoconductor drum includes a curable composition having about 20 to about 80 percent by weight of a charge transport molecule containing four radical polymerizable functional groups as exemplified below:

A method of preparing an organic photoconductor drum having a protective overcoat on its outermost surface is provided. In an example embodiment, a photoconductor drum having an electrically conductive substrate, a charge generation layer, a charge transport layer and an outermost protective overcoat layer is provided. The photoconductor drum is cured using a two-step process. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the photoconductor drum. A mask is sized and placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using ultraviolet light irradiation.

A method of curing a protective overcoat layer on the outermost portion of an organic photoconductor drum using dual curing process is provided. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the overcoated photoconductor drum. A mask or shield is sized to be placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using non-ionizing irradiation such as ultraviolet light.
