手提袋印刷过程中呈现杠痕是什么原因呢？济南手提袋印刷小编简单为大家分析一下手提袋印刷时出现杠痕的原因。

What is the reason for the bar marks in the process of handbag printing? Jinan handbag printing editor will briefly analyze the causes of bar marks in handbag printing.

1.滚筒齿轮磨损、齿轮空隙过大或是齿轮间有异物聚积。当滚筒齿轮磨损、空隙或齿间中有异物粘附状况时，机器工作过程中，各滚筒齿轮间不能精确地啮合，使滚筒之间的线速度不行共同。此外齿隙太大，滚筒也简单发生震颤颤动，构成印刷杠痕，使印品版面呈现一道道与齿轮节距附近的墨杠痕迹。

1. The drum gear is worn, the gear gap is too large, or there is foreign matter accumulation between the gears. When the drum gear is worn, the gap or there is adhesion of foreign matters between the teeth, the drum gears cannot be accurately meshed during the operation of the machine, so that the linear speed between the drums cannot be the same. In addition, if the backlash is too large, the drum will simply vibrate and form the print bar marks, which will make the print plate appear ink bar marks near the gear pitch.

2.胶辊要素引起的墨杠。当胶辊与印版间的触摸压力过大时，那么机器工作过程中，着墨辊与印版触摸滚刷时，就简单发生冲击而引起震颤，印刷这样摩擦力增大造成了条痕杠影。假如几根靠版式的着墨辊压力都太大，杠痕的密度将更大。对此，应经过调整胶辊与印版间的触摸压力，保持均匀、适度的触摸条件，消除过量的阻力后，墨杠才可得到较好的消除。

2. Ink bar caused by rubber roller element. When the touch pressure between the rubber roller and the printing plate is too large, when the inking roller and the printing plate touch the roller brush during the machine operation, it will simply impact and cause vibration, and the increased friction in the printing process will cause stripes and shadows. If the pressure of several inking rollers depending on the format is too high, the density of the bar marks will be greater. In this regard, the ink bar can only be better removed after adjusting the touch pressure between the rubber roller and the printing plate, maintaining a uniform and moderate touch condition, and eliminating excessive resistance.

此外印刷过程中由于水的挥发作用，会导致水墨粘度升高和PH值下降，PH值应控制在8．5—9．5之间，若超出此范围，可用PH稳定剂进行调节，保持粘度和PH值的稳定。一般情况下，水墨适于手提袋印刷高速印刷，低速印刷时若遇到干燥速度太快或印刷效果不佳的情况，可添加一定比例的慢干剂。

In addition, due to the volatilization of water during the printing process, the viscosity of ink will increase and the PH value will decrease. The PH value should be controlled between 8.5 and 9.5. If it exceeds this range, the PH stabilizer can be used to adjust it to maintain the stability of viscosity and PH value. In general, ink is suitable for high-speed printing of handbag printing. If the drying speed is too fast or the printing effect is poor during low-speed printing, a certain proportion of slow drying agent can be added.

印刷完毕后应将剩余水墨收集回相应的原装桶中或将墨槽的盖子盖严，以备下次使用，谨防由于水的挥发导致水墨表面结膜、变稠甚至变干。印刷后残留在印刷设置上的墨在其未完全干燥前可用清水冲洗，无法用清水洗净的墨可用清洗剂进行清洗。

After printing, the remaining ink should be collected back into the corresponding original bucket or the cover of the ink tank should be tightly closed for the next use, to prevent the ink surface from forming film, thickening or even drying due to the evaporation of water. The ink left on the printing device after printing can be washed with clean water before it is completely dry, and the ink that cannot be washed with clean water can be cleaned with detergent.
