PROBLEM TO BE SOLVED: To improve printing accuracy and to lengthen the lifetime by extending an ultra-thin stainless steel on an inside region of an image area, and forming Tetoron or the stainless steel in a composite plate via a junction. SOLUTION: In the combination plate 10 for full additive printed circuit board, a material of an image area 5 is calendered with small elongation to form a gauze (extra-thin stainless steel) 4, and the composite plate using a gauze (Tetron) 2 is formed as a support for absorbing printing strain. A junction 3 having a width of about 25mm for fixing the area 5 of a size of 700×700 mm is provided on the gauze (Tetron) 2. The gauze (stainless steel) 4 having a thickness of 60μm is calendered to be pressed to 30 to 50μm of its thickness and the gauze (stainless steel) 4 is extended on an inside region of the area 5. The gauze (Tetron) 2 and gauze (stainless steel) 4 are formed on the composite plate via the part 3, and an emulsion is formed in a thickness of 10 to 20μm.
