The high-precision printing of non-woven bags requires accurate overprinting. Roll-to-roll printing machines are printed by ink rollers. During offset printing, when the cloth is passed at high speed, the non-woven fabric will be deformed, the offset plate will be deformed, the ink color is thin, and the overprinting The effect will vary greatly.

Screen printing machine, semi-automatic printing machine, because the cloth is soft, the non-woven fabric is uneven, the suction function is not easy to use, and it is easy to shift. When placing the film, it is time-consuming and laborious, and the overprinting effect is not good. The roll-to-roll screen printing machine, from the feeding part to the coiling part, has a total length of hundreds of meters. , the deviation is large, then the fine set effect of manual printing is not to be mentioned.

In the actual customization of non-woven bags, the number and variety of accurate overprinting are also declining, so we will remove them from the table printing, and those that need exquisite effect printing are now mostly lamination printing. When dealing with this kind of accurate overprinted bags, you must be aware of it, deal with the overprinting problem well, and explain the above phenomenon to the customer, which can be handled well.
