Abstract: A method for writing an imageable material using multiple beams includes preparing subsequent patterns each having Y rows of N pixel locations, said subsequent patterns including first and second patterns; where the first and the second pattern overlap with each other in an overlap area consisting of O columns and Y rows of pixel locations; selecting for each row i of said first pattern Mi1 pixel locations; selecting for each row i of said second pattern Mi2 pixel locations; writing simultaneously, for each row i, said Mi1 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material; and moving said N beams relative to said imageable material in a slow scan direction over (N-O) pixel locations; writing simultaneously, for each row i, said Mi2 selected pixel locations by moving the N beams in a fast scan direction relative to said imageable material.

Abstract: A flexographic printing plate includes at least one halftone printing area with a plurality of halftone dots. A halftone dot of said plurality of halftone dots is shaped as a relief area. Said relief area includes a central portion and a surrounding portion. Said central portion has a central dot floor with a first pattern of a plurality of pins protruding upwardly from the central dot floor. Said surrounding portion protrudes upwardly from the central dot floor and has a top side including a second pattern of a plurality of recesses. The first pattern and second pattern are such that the surrounding portion can be distinguished from the central portion.

Abstract: A method for stereolithography printing, including the steps of positioning a holder containing a printing material in a first position in a stereolithography apparatus; stereolithography printing a plurality of successive layers in the holder using radiation for solidifying the printing material, such that one or more objects are formed; moving the holder from the first position to a second position away from the first position; opening the holder and removing the one or more objects from the opened holder, in the second position of the holder.
