LASER PLOTTER

The use of laser for marking and dividing board materials has a limited range of usable materials - cardboards, cartons, plexiglass. The advantage is the processing of financially available materials and the cutting speed, the disadvantage being, for example, cardboard tanned edge. The principle of the device is described using a 50W ULS laser plotter and 60x30cm working area. Data input is a vector .pdf file that can be created in any graphics program, and where the red lines represent a scratch and a blue cutting edge. The file is loaded into CorelDraw where data is scanned - scaling, line duplication, desktop coverage, and so on, and then forwarded to the laser plotter driver. It has a beam focus (material thickness), power and speed for individual drawing colors. For example, for a 1mm thick cardboard, 25% for full speed and 25% for full-rate performance at full speed. In black, raster processing can also be set, then the intensity of the laser output is assigned to individual grayscale, and the black and white image can then be burned onto the plate material at 500 dpi lines.

After the printing is started, the beam from the laser tube at the back of the device is fed through the mirror assembly and the lens into the cut material that is placed on the honeycomb pad. Throughout the entire cutting phase, smoke from the burnt material must be sucked out of the work area, and the optical lens must also be drawn through the air stream.
