Document Type and Number:
Japanese Patent JPH01237501
Kind Code:
A
Abstract:
PURPOSE:To prevent printing misregistration by forming register markers for registration of respective colors on the surface of a substrate opposite to the printing surface thereof. CONSTITUTION:The glass substrate 3 is positioned by a substrate positioning device 4 consisting of 3-point supports onto a substrate fixing surface plate 3 of a printing machine and thereafter, the substrate is fixed by vacuum chucks. A blanket or printing plate 1 on which ink is transferred to the patterns of color filters is rotated by a cylinder press printing method, by which the color filters are printed and formed on the glass substrate 2. The register markers 5b provided on the substrate fixing surface plate 3 and the register markers 5a provided on the surface of the substrate 2 opposite to the printing surface are mated with each other, by which the substrate is positioned. The parallax between the markers 5a and 5b is thereby eliminated and the misregistration is obviated. The man-hours for the registration are thus decreased and the color filters having no printing misregistration are obtd.
