General
Unlike conventional plate making production of direct laser engraved printing plates and rollers is a digitally controlled 3D process. Aspects of the formation of the image like the first step height, total relief height and shoulder width can all be controlled separately from the image detail.
Laser engraving occurs as a cylindrical process. Materials capable of being coated on roller or sleeve bases can be engraved with continuous seamless designs. The materials that can be applied to a roller or sleeve base include a wide range of photopolymers and elastomers..
High Definition
Printing traditionally uses halftoning to represent continuous tone (grayscale) images. Laser engraving can take advantage of the 3D aspects of a printing plate to offer a higher level of control than conventional platemaking processes. Due to the digital nature of the laser engraving process traditional halftone data can be combined with grayscale data in a number of ways. This adds control over the 3D details of an engraving, first step height, total relief and shoulder width, to the realtime imaging of the plate or roller. Significantly, this hybrid data can also extend the total number of grayscale (tone) equivalents a laser engraving can emulate without processing images at extremely high resolutions. Halftone line counts depend on the characteristics of the plate material being engraved and the type of laser used for engraving.
Materials
LASERLIFE LITTLEJOHN can supply and engrave a variety of plate materials. As laser engraving is not a photographic process, laser engraved plates can be made of photopolymer or opaque materials like natural or synthetic elastomers.
