摘要： An apparatus and method for calibration of laser ablating energy versus ablating depth for a laser ablateable printing plate in relation to materials forming the printing plate, includes a memory for storing data, for each of a plurality of materials, corresponding to correlated different detected depths of each of a plurality of laser ablated areas with ablating energy levels. A first laser ablates a printing image of desired depth in a printing plate formed by a selected one of the materials. A first control device interpolates laser ablating energy levels for the printing image of desired depth in the printing plate formed by the selected material, in accordance with the stored data and the selected material, and controls the laser to laser ablate the printing image in the printing plate of the selected material in accordance with the interpolated laser ablating energy levels.

摘要： A printing carrier sleeve for mounting printing plates thereon, is formed by cutting a sheet of flexible plastic material having opposite edges into a substantially rectangular shape of desired dimensions such that opposite edges are cut-away to provide complementary tabs and openings that interlock with each other, adhering printing plates on the sheet when the sheet is in a substantially flat condition, securing opposite edges of the sheet together in abutting relation so as to prevent air from passing between the opposite edges, and thereby forming the printing carrier sleeve in a cylindrical configuration, by placing a strip of tape on a forming cylinder, securing one edge of the rectangular sheet on the strip of tape on the cylinder, and wrapping the opposite edge of the sheet about the cylinder into abutting relation with the one edge to provide the interlocking arrangement.

摘要： Apparatus for balancing a printing roller having an image producing area thereon, includes a detector for detecting any unbalance of the printing roller during rotation thereof. A computer determines weight adjustments of the printing roller that are required to correct the unbalance, in response to the detection. A laser is controlled by the computer to remove material, in response to the determination, from at least one engraveable plate mounted on the outer surface of the printing roller or from the printing roller itself, in an area outside of the image producing area, in order to balance the printing roller.
