PROBLEM TO BE SOLVED: To solve quickly a amount of misregistration to be generated in printing. SOLUTION: In a method for control of printing wherein based on a amount of misregistration generated between printing with an adjacent upperstream side unit and printing with a downstream side unit when printing is executed on a long sized web continuously conveyed with a plurality of printing units, a position of a compensator roll 16 arranged between both units is moved to adjust a web length between both units, when the compensator roll 10 is moved in order to solve the misregistration detected on an outlet side of the downstream side unit per each control period, the moving speed V is varied by use of the formula containing a second order differential amount of the detected amount of misregistration Ek . |
