Abstract

PURPOSE:To make all of the titled device miniaturize comparing to conventional multicolor printing devices, by a method wherein printing units of which rolled sheet is pulled out in a spiral type and arranged in a diameter direction of a roll supporting axis, and it's printed part is made to pass in a dry box and dry treated. CONSTITUTION:Supporting frames 8 of screens 7 are positioned on guide rollers 5 which guide the shift of the rolled sheet A and support movable to the horizontal direction, and besides, a squeegee 9 for pushing out ink is fixed, and adequate printing is made to conduct on that rolled sheet A, supporting frames 8 being shifted at the same speed to the moving direction of the rolled sheet A. When printing is conducted on the rolled sheet A by printing units, since printing parts pass through inside of a dry box 1, a printing part is dry treated and then transferred to the next printing unit 4. Accordingly, print treating and dry treating of the rolled sheet A are reiterated alternately and printing of color numbers corresponding to the number of the printing units 4 are conducted.
