According to the introduction of plastic bag manufacturers, although the popularity of plastic bags is very high now, in fact, most consumers only know how to evaluate the quality of plastic bags from the aspects of shape design and design aesthetics. There are not so many people who really know the evaluation standard of plastic bag printing quality. Today, Jinan plastic bag customized small edition wants to focus on analyzing and interpreting this topic of conversation.

塑料袋印刷质量评估标准的中点，图案的要求。具体来说，图案要清晰完整，而且在塑料袋的表面不能有油墨留下的污点，同时，印刷色号必须要按照当时所设计的工艺单色号展开，同一个批次生产的塑料袋在颜色上不可有色差。另外，印制位置也要完全按照原本设计的去安排。

Plastic bag printing quality evaluation standard midpoint, pattern requirements. Specifically, the pattern shall be clear and complete, and there shall be no stains left by ink on the surface of the plastic bag. At the same time, the printing color number must be developed according to the process monochromatic number designed at that time, and the plastic bags produced in the same batch shall not have color difference in color. In addition, the printing position should be arranged completely according to the original design.

第二点，不能够存在大片印刷次点，所谓次点就是不足的点，允许值是每20个。

Second, there can be no large print secondary points. The so-called secondary points are insufficient points. The allowable value is 20 points per square meter.

第三，油墨剥离率必须要小于20%。需要提醒，在以上这三个塑料袋印刷质量评估标准中，第三点也就是油墨剥离率的理解难度，如果是新手的话，应该先从公式也就是A(油墨剥离率)=S1/S2*100%开始，弄清楚后再从实践角度出发去看一看到底在细节方面应该怎么把握。

Third, ink stripping rate must be less than 20%. It needs to be reminded that the third point in the above three evaluation standards of plastic bag printing quality is the difficulty of understanding the ink stripping rate. If you are a novice, you should start with the formula a (ink stripping rate) = S1 / S2 * 100%, and then see how to grasp the details from the perspective of practice.

在一些人看来，塑料袋印刷是一个没有技术含量的工作，只需要监管着机器按部就班执行就可以了。其实并不是的，在印刷完成后，必须要通过抽检方式来了解一下到底这一批塑料袋的每一个细节是否都达到了应有的标准，否则要“回炉重造”。

In some people's view, plastic bag printing is a work without technical content, just need to supervise the machine to carry out step by step. In fact, it's not. After printing, it's necessary to find out whether every detail of this batch of plastic bags has reached the required standard through sampling inspection. Otherwise, it's necessary to "return to the furnace for reconstruction".
