FIELD: process engineering.SUBSTANCE: invention relates to packing equipment, machine building and instrument making, particularly, to direct-action printers, and aims at increasing printer rate and decreasing its sizes. Proposed laser matrix printers uses the line of, at least, five laser emitters for scanning the image pattern over its height, discrete single-emitter diode lasers, and integral optical system. Data line printing is performed by burning off of label or package surface layer points of image pattern perplexing in colour or shade relative to underlayer or substrate.EFFECT: higher security against counterfeit, decreased sizes and simplified design.5 dwg |
