Why silk screen works well

The printing process of eco-friendly shopping bags generally uses screen printing, which is often referred to as “silk screen printing”. However, in the actual production process, customers often say: Why do some bags have good printing results and some have poor printing results? Of course, this is closely related to the proficiency of printing workers and printing technology. At the same time, on the other hand, it has a great relationship with the choice of printing inks. In general, there are two kinds of printing inks available for us to choose from, one is a water-based adhesive paste and the other is an ink. For example, the printing on general non-woven bags is based on the use of water-based mortar, the most prominent feature of this type of water-based mortar is that the effect after printing has obvious concavity and convexity, and the coverage rate is good, washable, and Basically there is no odor, and the ink is generally used in the screen printing of common objects, such as the surface of a metal box, etc. The greatest feature of this printing process is high printing accuracy. Why do we basically use water-based mortar for printing on our eco bags? This mainly has the following reasons:

1. Water-based mortar is a relatively environmentally-friendly ink, and there is basically no odor. Therefore, since we are doing eco-bags, we must choose environmentally friendly inks.

2. Different from the surface of ordinary objects, the mesh of the cloth surface is relatively large, and the general ink printing is selected. If the coverage rate is not good, that is, after the printing is finished, many backgrounds of the cloth itself are exposed. Such printing The effect can be ugly, so the surface properties of the fabric itself determine the use of water-based mortar.

Another situation is that some customers' orders need to be exported to some countries in Europe and the United States. Therefore, relatively speaking, there is a higher demand for the environmental performance of ink. At this time, we need to be more cautious to avoid import declarations in other countries. Can not pass the environmental protection test. In this case, we generally recommend customers to choose those water-based mortars with high environmental performance. This water-based elastomer with high environmental performance not only has a low content of heavy metals, but also has good color fastness (adhesion to the surface color of fabrics). ) and washability better. Of course good water-based mortars have high production costs, but for high-end customers, we still have to provide a better product quality. As a manufacturer with many years of production of eco-friendly bags, we have always been in the attitude of the customer's responsible person. No matter what kind of customer requirements, we will provide our customers with the best quality service.
