Reproduction process using infrared radiation
Abstract
Abstract A method is disclosed of making an image on a layer, which comprises exposing a layer of polyethylene to infrared radiation in heat-conductive relation with a master to form a latent image, charging the layer with an electrostatic charge at a substantially later time to produce a charge image corresponding to the latent image, developing the charge image with a toner, and fusing the toner to said layer. A method of making an offset printing plate is also disclosed which comprises exposing a layer of cellulose acetate to infrared radiation in heat-conductive relation with a master to form a latent image corresponding to the master, charging the layer electrostatically at a substantially later time to produce a charge image, developing the charge image by applying a toner, fusing the toner to said layer and saponifying the surface of said layer to render the non-image areas hydrophilic thereby forming a layer suitable for use as an offset printing plate.
