Apparatus and method for controlling ink supply amount/registration adjustment in printing press

An apparatus for controlling ink supply amount/registration adjustment in a printing press, including

• a base on which a printing product printed by the printing press is set,
• a sensor head,
• sensor head moving means for moving the sensor head laterally and upward/downward on the base,
• a first detector which is mounted on the sensor head, and measures color matching data of a color patch of each color in a color bar printed in a margin of the printing product,
• a second detector which detects a position of a register mark of each color, which is printed in a margin of the printing product, and
• control means for, when the sensor head moves laterally, controlling an ink supply amount of each color in the printing press based on the color matching data of the color patch of each color in the color bar, which is measured by the first detector, and adjusting registration of each color in the printing press based on the position of the register mark of each color, which is measured by the second detector,
• the sensor head moving means comprising upward/downward position adjusting means for adjusting a upward/downward position of the sensor head,
• wherein the second detector detects a upward/downward position of the color bar when the color matching data of the color patch of each color in the color bar is measured by the first detector, and
• said upward/downward position adjusting means 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.
