Abstract

Disclosed is a carton former, etc., provided with a camera which acquires an image of a printed face printed on a carton forming sheet by a printing unit; and a register correction control unit which obtains a register misalignment amount of each printing unit by comparing a specific picture of a master image which is a print sample, with a picture in an area of an image on a printed surface acquired by the camera, the area being designated in accordance with the specific picture, and corrects the register of printing by controlling a register adjustment mechanism attached to each printing unit on the basis of the register misalignment amount.

Description

Technical field [0001] The present invention relates to a box-making equipment that prints multiple colors on a sheet surface, and particularly relates to a box-making equipment and an inspection unit provided with a unit for color correction registration ([日] see the right) (registration adjustment), And the printing registration control method for the box-making equipment. Background technique [0002] Some box-making equipment that produces boxes from box sheets (for example, corrugated cardboard sheets) include a paper feed section, a printing section, a paper discharge section, a die cutting section, and a folding section (folding gluing machine) in this order from the upstream side Section) and counting discharge section. In such a box-making equipment, the paper feeding section is loaded with box sheets, and the box sheets are fed to the printing section on a sheet-by-sheet basis. At the printing section, a plurality of printing units are provided therein Print the corre...
