Abstract
Disclosed is a seamless cylindrical printing screen having an improved aperture ratio and high strength, rigidity and durability sufficient to resist the rotary screen printing operation and being capable of providing high quality printed patterns with sharp and clear contours. This screen is composed of a meshed metal cylinder, in which said cylinder comprises a plurality of axial mother lines composed of a metal wire and extended from one open edge of the cylinder to the other open edge substantially in the axial direction at small intervals between every two adjacent axial mother lines, a circumferential mother line composed of a metal wire and extended spirally from one open edge of the cylinder to the other open edge at small intervals between every two adjacent turns of the circumferential mother line to cross said axial mother lines and a metal plating layer covering the peripheries of said circumferential and axial mother lines and bonding them to one another at the crossing points thereof.
