A printed object management apparatus () is provided with: a line sensor (); a spectrophotometer (); an area camera (); a print quality-inspecting unit (A) for inspecting the quality of the overall pattern of a printed object () on the basis of data input from the line sensor (); a print density controlling unit (B) for controlling, on the basis of data input from the spectrophotometer (), the amount of ink supplied so that the ink density equals the reference density; and an inter-color registering unit (C) for detecting register marks printed on the printed object () on the basis of data input from the area camera () and aligning the patterns between the various colors. The apparatus is configured so as to support the line sensor (), the spectrophotometer () and the area camera () on a single scanning head ().

Printed object management apparatus and management method

This invention discloses an apparatus for controlling ink supply amount/registration adjustment in a printing press. The apparatus includes a base, sensor head, sensor head moving unit, first detector, second detector, and control unit. The sensor head moving unit includes a upward/downward position adjusting unit which adjusts the upward/downward position of the sensor head. The second detector detects the upward/downward position of a color bar when color matching data of a color patch of each color in the color bar is measured by the first detector. The upward/downward position adjusting unit adjusts the upward/downward position of the sensor head based on the upward/downward position of the color bar, which is detected by the second detector. A method of controlling ink supply amount/registration adjustment in a printing press is also disclosed.
