自动转印过程中印刷机滚筒的加速与定相方法
Abstract:
公开了一种用于在自动转印操作过程中准备用于在卷筒纸(11)上进行印刷的滚筒的方法。该方法包括以下步骤，即利用至少一个第一印刷滚筒(22、26、30、34)在卷筒纸(11)上印刷图像；加速至少一个第二印刷滚筒(24、28、32、36)，以使得所述至少一个第二印刷滚筒(24、28、32、36)的表面速度等于所述卷筒纸(11)的速度；在所述加速步骤的过程中并且在所述至少一个第二印刷滚筒(24、28、32、36)的表面速度等于所述卷筒纸(11)的速度之前，调整所述至少一个第二印刷滚筒(24、28、32、36)相对于所述卷筒纸(11)的相位；将所述至少一个第一印刷滚筒(22、26、30、34)自所述卷筒纸(11)移动离开，并且将所述至少一个第二印刷滚筒(24、28、32、36)朝向所述卷筒纸(11)移动；以及利用所述至少一个第二印刷滚筒(24、28、32、36)在所述卷筒纸(11)上印刷图像。还提供了一种构造成自动转印的印刷机。
Abstract(English):

A method of preparing cylinders for printing on a web (11) during auto transfer operations is provided. The method includes the steps of printing images on a web (11) with at least one first printing cylinder (22, 26, 30, 34); accelerating at least one second printing cylinder (24, 28, 32, 36) so that the at least one second printing cylinder (24, 28, 32, 36) has a surface velocity that equals a velocity of the web (vw); adjusting a phasing of the at least one second printing cylinder (24, 28, 32, 36) with respect to the web (11) during the accelerating step and before the surface velocity of the at least one second printing cylinder (24, 28, 32, 36) equals the velocity of the web (11); moving the at least one first printing cylinder (22, 26, 30, 34) away from the web (11) and moving the at least one second printing cylinder (24, 28, 32, 36) towards the web (11); and printing images on the web (11) with the at least one second printing cylinder(24, 28, 32, 36). A printing press configured for auto transfer is also provided.
