Abstract
PURPOSE: To make drop-out, by printing the pattern not to be detected in thin lines, in the document used for the picture read-in unit.
CONSTITUTION: The read-in area 15 of the document 1 consists of the drop-out color section 16 by screen process printing and the character describing area 17. The drop-out color section 16 is the screen process printing section having a plurality of net lines and the color of net lines is purple. In reading in the net line pattern with the optical system, the difference of the amplitude of signal in reading in the colored part and the white part, is smaller when the space frequency of the net line pattern is greater, allowing to use the net line pattern as the drop-out color section through the adjustment of the space frequency and the shadow area.
