Abstract: When initially routing a continuous web along a path, the web walks across the width of the path, and uneven tension occurs causing the web to break in some cases when printing tension is applied thereto. Further, uneven web tension is produced on the right and left of the web by excessive walk control resulting from an excessive deviation of the web from the target position of a walk controller, with the result that the web is crumpled and broken. These problems are solved by maintaining a web tension that is lower than the printing tension until the web position converges on the target position of the walk controller after loading of the web, thereby reducing the amount of correction by the walk controller and the amount of web lost in the preparatory phase before printing, with the result that excellent image quality free from crumple or breakdown is ensured.

Abstract: A printing device reads an image on a printing paper with an image pickup part. It image-processes obtained image data in a control part, and operates the positions of respective register marks (R1 to R4). It operates the quantity of displacement necessary for positioning an image. It obtains an offset count number Co for deciding an image recording starting position from the obtained quantity of displacement. It stores the obtained offset count number Co while obtaining starting position data. Then, dimensional correction data for the image is calculated. The image on the printing paper is first picked up, and the necessary quantity of displacement is calculated. A speed coefficient k is calculated for changing the rotational speed of a plate cylinder. Following this, a correction quantity by a Cd default count number previously set for deciding the image recording starting position is changed. Accordingly, the offset count number Co is calculated again on the basis of the obtained speed variable k.
