Abstract: PURPOSE:To hold an optimum printing pressure by providing an actuator using compressed air to vertically move a squeegee, an electropneumatic regulator for varying the pressure of compressed air to be supplied to the actuator by an electric signal, and a solenoid valve for switching the flowing direction of the air. CONSTITUTION:When compressed air is supplied to the upper end of an actuator 17 through a solenoid valve 21 and an electropneumatic regulator 20, a piston rod 19 is moved down. A squeegee 14 is moved down through a holder 15 and guide shafts 16a, 16b to be brought into contact with a screen 11, and further energized downward. A force for energizing the squeegee 14 downward (printing pressure) is decided by the pressure of the compressed air set by the regulator 20. Even if the height size of a printed board 13 is varied on the way of moving the plate 18, the force for energizing the squeegee 14 down (printing pressure) is not varied, but an optimum printing pressure set by the regulator 20 is held.

IPC: G03B27/72
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate the futile use of a photographic printing paper caused by the production of a print not having a picture at all, due to the setting of reference exposure conditions by measuring the density of the solid part of the print with a densitometer and setting the reference exposure conditions, based on the density of the solid part measured with the densitometer.

Then, the density is transmitted to an overall controller 900. Then, the overall controller 900 obtains the reference exposure conditions from the transmitted density and transmits information on the obtained reference exposure conditions to the exposure part 200, so that the exposure part 200 executes the exposure, based on the transmitted reference exposure conditions. In the density measuring part 100, a position in the width direction of carrying the print is regulated by a guide. Thus, the density at the fixed position of the print after the position in the width direction of carrying the print is regulated is measured by the densitometer.
