METHOD FOR APPLICATION OF RASTER IMAGE Russian patent published in 2009 - IPC B41M5/24 

FIELD: technological processes.

SUBSTANCE: invention may be used in systems of laser marking and engraving in industry, for artistic applications, for authentication and personification of items and documents. Method for application of raster image consists in the fact that image of original is introduced into computer, image is transformed into raster array of numbers, working element coordinates are changed, working element is put in action, and dots are applied with its help onto surface of item. Working element used is represented by laser radiation. At the same time test image is previously downloaded into computer, and this image is applied onto surface of test sample, produced result is assessed, and laser radiation properties are accordingly adjusted in compliance with it. Multistage filtration of raster array of numbers is carried out, afterwards image of original is marked onto item.

EFFECT: high quality of applied image, increased resource of equipment, higher speed of image application, and also expansion of field of materials suitable for application of images.
