Abstract
A screen process printing method of performing solid printing on a printing substrate with a printing ink, using (a) a squeegee, (b) a screen pattern plate through which the printing ink is brushed or squeezed so as to form a solid ink transferred portion on the printing substrate by the squeegee which is in contact with the screen pattern plate, with the screen pattern plate coming into contact with the printing substrate and separating therefrom, (c) a back-up roller which is disposed so as to be directed to the screen pattern plate and the squeegee, and around which the printing substrate is wound, and (d) a gas ejection slit from which a gas is ejected, includes a step of ejecting the gas from the gas ejection slit toward a separate portion at which the printing substrate separates away from the screen pattern plate, thereby smoothing the surface of the solid ink transferred portion on the printing substrate, and a screen printing machine for carrying out this screen process printing method is provided.
