不干胶标签印刷可以注重哪些小窍门?

1. Skillfully remove the impression of paper roller
在不干胶标签印刷过程中,收纸部位的压纸轮往往会将材料压出印痕,工厂不得不将材料加宽(一般比实际印刷宽度多10mm),让压纸轮压在材料的边缘,以避免印痕出现在成品标签的表面。但是这种方法很浪费原材料,其实,笔者推荐在压纸轮表面贴上一层不干胶材料(纸张、薄膜材质均可,推荐使用PET材料,效果好),能够大大减轻压纸轮在材料表面压出的印痕。采用这种方法后,我们可以用小宽度的原材料印刷标签,大大减少了原材料的浪费。
In the process of self-adhesive label printing, the paper roller in the paper receiving part often presses the material out of the impression, so the factory has to widen the material (generally 10 mm more than the actual printing width), so that the paper roller presses on the edge of the material to avoid the impression on the surface of the finished label. However, this method is a waste of raw materials. In fact, the author recommends sticking a layer of self-adhesive material on the surface of the paper roller (paper and film materials can be used, PET material is recommended, and the effect is good), which can greatly reduce the impression of the paper roller on the surface of the material. With this method, we can use small width of raw materials to print labels, greatly reducing the waste of raw materials.
2、巧除静电干扰
2. Eliminating electrostatic interference
冬季印刷薄膜材料,经常会出现材料收卷不齐和印刷机操作系统死机的现象。由于静电的干扰导致设备的操作系统经常死机而不能正常工作,同时也导致薄膜材料收卷不齐。当在车间里加了两台加湿器,提高车间的相对湿度,大大减小了静电对设备和材料的影响,终生产得以顺利进行。
When printing thin film materials in winter, there are often phenomena of uneven material winding and printing machine operating system crash. Due to the interference of static electricity, the operating system of the equipment often crashes and cannot work normally. At the same time, it also leads to the uneven winding of film materials. When two humidifiers are added in the workshop, the relative humidity of the workshop is improved, the influence of static electricity on the equipment and materials is greatly reduced, and the final production can be carried out smoothly.

3、印刷撤淡剂去除白点
3. Removing white spots with printing diluent
制一块实地版,在原材料表面先印刷一遍UV撤淡剂,然后再按正常工艺印刷油墨。由于先印刷的UV撤淡剂已经将原材料表面的灰尘粘走或覆盖,后面印刷油墨时基本上就不会出现白点了。而且,由于UV撤淡剂的颜色很淡,不会影响到后面印刷油墨的色相。但是这样做会大大提高生产成本,因此只可以用来应急,并不能作为一种常规的解决方法。
Make a field plate, print UV diluent on the surface of raw materials, and then print ink according to the normal process. Due to the first printing of UV light remover has been the dust on the surface of raw materials to stick away or cover, when printing ink behind, basically there will be no white spots. Moreover, because the color of UV diluent is very light, it will not affect the hue of printing ink. But this will greatly increase the production cost, so it can only be used for emergency, and can not be used as a conventional solution.
4、局部调整贴版的双面胶厚度,达到理想印刷效果
4. Adjust the thickness of the double-sided adhesive tape to achieve the ideal printing effect
在不干胶标签印刷过程中常常会出现局部区域印刷颜色过深或过浅的情况,此时可以通过调整局部贴版双面胶厚度的方法来解决,而无须重新出胶片晒版。具体的做法是:若局部区域印刷颜色过深,可以将该区域印版下面的双面胶除掉,相当于减轻了局部的印刷压力,印刷颜色会浅一些。同样的,若局部区域印刷颜色过浅,可以在该区域的印版下面再加一层双面胶,这样相当于增加了局部的印刷压力,印刷颜色可以加深。通过这种方式调节图文局部压力,往往能解决一些问题并能够避免重新出胶片、制版带来的麻烦,同时也节约了版材。
In the process of self-adhesive label printing, the printing color of local area is often too dark or too light. At this time, the problem can be solved by adjusting the thickness of local plate sticking double-sided adhesive tape, without re printing the film. The specific method is: if the local area printing color is too deep, you can remove the double-sided adhesive tape under the plate in this area, which is equivalent to reducing the local printing pressure, and the printing color will be lighter. Similarly, if the printing color of local area is too light, a layer of double-sided adhesive tape can be added under the printing plate of this area, which is equivalent to increasing the printing pressure of local area, and the printing color can be deepened. Through this way to adjust the local pressure of graphics and text, we can often solve some problems and avoid the trouble of re production of film and plate making. At the same time, we also save plate material.
