In life, we have seen a variety of non-woven bags, and the printing colors of the bags are also various, some are rich and colorful, and some are plain and simple. How exactly are woven bags printed?
There are many printing methods for non-woven bag printing, but we usually use screen printing. Screen printing has the advantages of fast printing speed, clear and neat printing and relatively cheap price, so we generally use it. The printing methods are screen printing. However, screen printing has another imperfection, that is, screen printing generally cannot print too many colors, and if there are too many colors, the color registration is easy to be inaccurate. Therefore, if the screen printing process is generally used, the printing color is best controlled within 4 colors, and these 4 colors cannot be gradient colors, but must be solid colors. If there are gradient colors or color overlays, then screen printing cannot achieve this effect, and other printing methods need to be used.
If there is a gradient in the color or the color is more multi-colored, it can be made by thermal transfer or gravure lamination color printing. Thermal transfer printing is mainly aimed at a relatively small printing area. It does not matter if the color is multi-colored. The printable area must be small, because thermal transfer printing is charged according to the printing area. The larger the printing, the higher the cost, and vice versa. The smaller the printing area, the cheaper the cost.
If the printing area is relatively large, especially the full-page color printing, it is recommended to color gravure lamination color printing. The gravure printed non-woven three-dimensional bag handbag not only has exquisite printing patterns and rich colors, but also after laminating, the thickness of the bag increases, and the corresponding bearing capacity also increases naturally. Especially when the number of orders is relatively large, it is more suitable to use lamination gravure printing. Gravure lamination color printing is a printing process with the best printing effect and printing accuracy in similar printing.
