摘要： A predecorated gypsum wallboard and the method of manufacture wherein a protective base coat is applied on the face paper by a rotogravure printing of the protective coat with minute openings very closely spaced throughout the coating, as by printing the coat in the form of reasonably uniformly sized tiny dots with about 1000 to about 100,000 dots per square inch, a decorative coat is applied over the base coat, gypsum wallboard is formed with the coated surface of the paper on the outside face, and the newly formed wallboard, when hardened, is dried by heating and removing water from the gypsum core through the still porous coated paper.
