Abstract: A lithographic printing plate precursor and process for its utilization have been discovered through which negative and positive original images can be printably reproduced on the plate precursor in substantially fewer development steps. The precursor plate is exposed sequentially to either the negative or positive original with the resultant image subsequently developable in a single process or step. The process is achieved by using a precursor plate having two coatings of significantly different photographic sensitivity to light, i.e., speed as characterized by "camera speed" or "contact speed" and imagewise exposing the originals in sequence to alternative speeds. The contact speed coating may be negative-working or positive working while the camera speed coating is negative-working. The camera speed coating is developed followed by exposure of the contact speed coating. Images produced at camera speed are removed and non-image bearing portions of the contact speed coating are removed.

Abstract: A direct color thermal printing method records a full-color image containing black characters on a thermosensitive color recording medium having three laminated thermosensitive recording layers. Three color components of each pixel are sequentially read out from three color frame memories. If all of the three color components of a pixel correspond to the maximum densities, that pixel is determined to be printed in black, and is stored as black pixel data in a black line buffer memory. When recording the black pixels, a thermal head is driven to apply a predetermined maximum amount of head energy to the thermosensitive color recording medium, for simultaneously coloring the three thermosensitive recording layers in accordance with the black pixel data.

Abstract: A photolithographic method wherein a mask is made by pattern exposing and developing a o-quinone diazide sensitized phenol-formaldehyde resist layer, the formed resist mask then being used directly as an exposure mask for a layer of deep ultraviolet (less than 3000A) sensitive resist such as an alkyl methacrylate resist.Since alkyl methacrylate resists are not sensitive to light above 3000A and phenol-formaldehyde resists are opaque to light below 3000A, phenol-formaldehyde resists may be used directly as photoexposure masks for alkyl methacrylate resists using any broad band exposure light source which includes deep ultraviolet.
