摘要: Method of forming a color image graphic object pattern directly on support medium. A water-soluble photosensitive stencil material is coated the and exposed imagewise to actinic radiation. The developed remove water-soluble, unexposed material. layer water-permeable, water-insoluble medium applied. treated with water or an aqueous solution permeate soften which removed by mechanical action. Alternatively, material, becomes exposure radiation, may be support.
