Printing screen making apparatus

摘要

A tension obtaining unit obtains a measured tension value by measuring tension in sub-areas where tension should be obtained, which are set in a screen area to perforate of a stretched screen master. A control unit calculates tension in sub-areas where tension should not be obtained of the screen area to perforate as computed tension values by modifying the measured tension value, based on predefined information for tension computation. The control unit compares the measured tension value and computed tension values against information for determining perforation conditions stored in a storage unit and controls a screen making unit to execute perforation on determined perforation conditions fit for tension in the sub-areas where tension should be obtained and for tension in the sub-areas where tension should not be obtained.

1. A printing screen making apparatus comprising:
a perforation unit that moves relatively to a stretched screen master prepared by stretching a screen master made of a mesh fabric and a thermally fusible film on a frame in a tense state with predetermined tensile force and thermally fuses and perforates segments of the film corresponding to image components in original data; a tension obtaining unit that obtains tension in a predetermined screen area to perforate of the stretched screen master; and a control unit that controls the perforation unit to execute perforation on perforation conditions set according to tension obtained by the tension obtaining unit.
