摘要： As ink is conveyed through the inking unit of a printing machine, a state of equilibrium occurs which ensures adequate inking of the printing plate during continuous printing. The equilibrium state includes different ink gradients for the respective printing zones superimposed on a uniform base level. In order to achieve the state of equilibrium rapidly and easily at the start of printing, an ink distribution is produced in the inking unit before printing closely matching the state of equilibrium for continuous printing. An accurately defined ink film distribution is initially fed to the inking unit rollers via the vibrator. Preferably, when the ink applicator rollers are thrown off of the plate cylinder and the sheet feed is off, a predetermined amount of ink is introduced to the inking unit. The vibrator is then shut off and the base level of ink is allowed to become uniformly distributed. Next the ink profile is set at the ink metering elements and the vibrator is turned on. When the ink profile propagates to the applicator rollers, the applicator rollers are thrown on to the plate cylinder and the sheet feed is turned on.
摘要翻译：当墨水通过印刷机的着墨单元输送时，发生平衡状态，确保在连续印刷期间印刷板的充分着墨。平衡状态包括叠加在均匀基底水平上的各印刷区域的不同油墨梯度。为了在印刷开始时快速且容易地达到平衡状态，在印刷之前在着墨单元中产生与分配状态匹配以进行连续印刷的油墨分布。首先通过振动器将准确定义的油墨分配物送入着墨单元辊。优选地，当油墨涂布辊从印版滚筒抛出并且进纸被关闭时，预定量的墨水被引入到着墨单元。然后关闭振动器，使墨水的基准水平均匀分布。接下来，将墨水轮廓设置在墨水计量元件上并且振动器被打开。当油墨轮廓传播到涂布辊时，涂布辊被扔到印版滚筒上并且片材进给被打开。
