Abstract
Method of making electrostatographic multi-color reproductions on plain bond paper receiver sheets in such a manner that the sheets have the high quality look of coated paper while not being subject to the coated paper problems of blistering and differences in gloss level build up. According to the method of this invention, electrostatographically formed color images of information to be reproduced are respectively developed with corresponding colored marking particles, and a negative image of the information to be reproduced is developed with white marking particles. The marking particle developed images are sequentially transferred to a plain bond paper receiver sheet in superimposed register. The transferred images are then fixed to the receiver sheet by application of heat and/or pressure. The white marking particles cover the area of the receiver sheet not covered by the colored marking particles. Since substantially the entire surface area of the receiver sheet is covered with marking particles, after fixing of the marking particles to the receiver sheet, the sheet has a high quality glossy appearance without any appreciable relief effect due to differences in gloss level build up.
