PROBLEM TO BE SOLVED: To realize curved surface offset printing, in which an ink repelling layer having cushioning properties is used in the presence of dampening water instead of the conventional, recess formation of dry offset printing and then ink is transferred to a transferring pad or the like. SOLUTION: This curved surface offset printing method is the method of lithographic printing plate equipped with a hydrophilic swelling layer on board and has high ink repellency without carrying out non-sensitizing treatment and using pure water as dampening water and is employed with an ink repelling layer having cushioning properties. Thus, by transferring ink to a transferring pad or the like, a curved surface offset printing can be realized. |
