Non-woven bag printing is generally screen printing, divided into watermark, ink printing, and offset printing. The cost of ink printing is relatively low, and offset printing is the highest. The above printing can only print simple colors. If there are gradual colors, it can only use the process of laminating or thermal transfer, but the cost is higher. It is more difficult to print gradient colors for non-woven bags. Non-woven bags have the same properties as plastic bags and are more environmentally friendly. However, there are some restrictions on printing to print up to three colors. Of course, it is difficult to grasp the accuracy of color registration if more can be printed. Because this is all hand-printed on a silkscreen, the chromaticity is easy to run out of color. In fact, it is not that the more colors the better, sometimes in line with the color design level, the monochrome non-woven handbag printing can also exert the incomparably fashionable advertising charm.
