A printing material 3 having a polyimide solid content of 3.8%, for example, is formed in a predetermined film thickness on a glass plate 4 having a thickness of about 0.7 to 1.1 mm by using a spinner. This is set on the table 5. Next, the printing material 9 is transferred to the printing plate 2 by pressing while rotating the printing roller 1 to which the printing plate 2 made of, for example, a Sirel material is attached. Further, this printing material is transferred onto the glass substrate 7 as shown in the figure to form a printing film 8.
