METHOD AND DEVICE FOR CONTROLLED MATERIAL TRANSFER Russian patent published in 2004 - IPC

FIELD: printing engineering.

SUBSTANCE: method involves treating material spread over transparent carrier with radiation impulses premodulated with spatial modulator unit and passed through amplifying medium and optic system. The optic system controls image position built with the spatial modulator unit in a way that pressure impulses arise in incident radiation areas. They transfer a portion of material onto an object set in front of the transparent carrier building given image on the object. Device has the spatial modulator unit, amplifying medium (radiation source), elements for controlling radiation, transparent carrier and object on which an image is to be built with the material coating the transparent carrier.

EFFECT: high efficiency in transferring material; long service life.
