Laser Engraving Ideas
Through the active modulation of the intensity waveform and the independent change of the energy of each laser pulse, the shape, diameter and depth of each single cell can be independently determined. This new type of mesh in the plate making process is called Super Laser Engraving Ideas, which is an extension of the mesh (the depth and diameter of the semi-automatic mesh are variable, but cannot be controlled independently). Modulation allows a single laser system to sculpt a variety of cavities (traditional, Autotypical, Halfautotypical). In the past, different processes were required (electromechanical engraving, chemical etching). New mesh shapes can now be generated to optimize ink transfer characteristics and printability for each color% -tone value and printed substrate.
In addition to the "single shot and single hole" method of SHC beam waveform modulation Laser Engraving Ideas, it is also possible to design engraving meshes by superposing continuous laser pulses, but the diameter of the light spot is smaller than the required mesh size (such as the diameter of the light spot 10-15 microns, cell size 100 microns). The shape and internal structure of the formed cavity depends on the scanning scheme of modulation, overlap and laser pulses (such as the scanning algorithm of image typesetting machine). The continuous wave Laser Engraver is switched or gray-scale modulated, and can sculpt small overlapping stripes to form a rhombic mesh. Its advantage lies in the high resolution of the image (for example, the resolution reaches 1000 lines / cm and the light spot diameter is 15-20 microns when the forward conveying step is 10 microns). The disadvantage lies in the loss of production capacity, which needs to be compensated by using a higher modulation frequency (about 1 MHz) and a multi-beam engraving head.
