Abstract

Nonimpact printing can be accomplished by a distillation printing method in which a layer of radiation absorbing material or transducer is coated with a vaporizable material. By selectively irradiating this material, the vaporizable material evaporates in the irradiated areas and condenses on a copy sheet. The latter can be developed with toner particles or with sonie other developing technique.

Distillation Printing

Nonimpact printing can be accomplished by a distillation printing method in which a layer of radiation absorbing material or transducer is coated with a vaporizable material. By selectively irradiating this material, the vaporizable material evaporates in the irradiated areas and condenses on a copy sheet. The latter can be developed with toner particles or with sonie other developing technique.

This method can be achieved with light source 1, such as a laser, having its output directed into optical character generator 2 and light deflector 3. The output of the light from deflector 3 writes the character on the back of moving web 4, coated with vaporizable material 5.

The areas of web 4 exposed to the light are heated and cause material 5 to evaporate and condense on copy paper 6 adjacent material 5. As shown in drawing 2, web 4 comprises substrate 7 carrying light absorbing layer 8. On layer 8 is coated material 5. When web 4 is in the exposure position, material 5 is adjacent paper 6.
