Operation of the light valves, includes setting the light valves to block and/or allow pulses of laser energy propagating from the laser drilling system that can ablate a linear pattern of cells along a substantially entire length of the gravure cylinder blank. Drilling of cells includes targeting the laser drilling system on the gravure cylinder blank, such that ablation of materials occurs as sub-beams propagate along an optical path to the target area and impinge upon the gravure cylinder blank, wherein specific cells within the target area of the gravure cylinder blank are drilled or not drilled according to settings of the light valves.Field of SearchBlanks and processesRolling contact Scan of light Specific light modulator THIN FILM LASER PARTICULAR BEAM CONTROL DEVICE Q-switch Absorption type Mode locking Control of pulse characteristics Modulation Controlling light intensity Excimer or exciplex Character or design formed on printing surface (e.g., intaglio) | |
