Technologies & Techniques Segment Specific Printing Plates Delivered in Roll Form to Minimize Waste and expedite engraving Time By Armin senne Going back more than 600 years, most of us know that the world of industrial printing owes its origin to Johannes Guttenberg in Germany. With the newly developed calendar technology printing plates for flexo, we can see that the spirit of innovation still continues to flourish. In fact, it jump started the development of a brand-new in- dustrial process for manufacturing a four-class series of flexo printing plates, supplied to the market as roll goods for direct laser engraving. Between them, these plates embrace the full range of market application needs for flexo printing. Plate systems with integrated substrate comprise a print layer and a compress- ible layer, which neutralizes the forces acting on the printing nip and the base layer. Products are supplied as 10-meter rolls in widths up to 2,100 mm and in various thicknesses. This permits the user to cut off only as much as is needed for a particular job. Thus waste is greatly reduced. For production of the flexo printing form, the rolls are merely mounted in the lengths actually required depending on the job to be engraved. This not only saves on the cost of plates (less waste) but also considerably reduces the time required for direct engraving. Blister-free, secure mounting of elastomer plates with a compressible base, which is cut to length from the roll, is done with a few simple steps. Long service life and low abrasive wear is characteristic.
