Anti sticking is a common quality issue in printing with environmentally friendly water-based ink. There are various factors that can cause this issue. Let‘s take a look at the reasons that can lead to anti sticking during printing:
1. Quality issues with ink wash: Some printing factories may use very cheap ink wash in pursuit of higher profits, so it is inevitable that this situation will occur. Once it is found that the quality of ink wash is causing anti sticking, it should be replaced promptly.
2. Poor drying is a printing process issue, where the drying speed of ink does not match the machine speed, and there is a mismatch between the oven and temperature. If poor drying is found, the machine equipment, drying time, and other factors should be checked to gradually identify the cause.
3. Some printing layouts may experience anti sticking due to layout design and placement after printing, especially in multi-layer overlay printing where the impact of anti sticking is even greater.

Solution for anti sticking:
1. The workshop should adjust the appropriate winding tension according to different printing materials and keep relevant data records. The optimal tension of the machine is suitable for manual softness and hardness. Especially, transparent ink should not be pressed by the winding roller.
2. Choose ink with good drying performance, pay attention to communication with ink suppliers, product structure, and ink requirements. If there is more than one color printing film, multiple films can be used and treated with cold air.
3. The purity of the solvent should be tested in each batch, and specific requirements should be made to the solvent supplier. Please remember not to store and extract solvents in damp places. A cool and ventilated storage area is the best storage location.
4. Pay attention to checking whether the drying temperature of the printing equipment is normal and stable, especially whether the inlet and outlet air volume are matched.
5. When designing the layout, attention should be paid to the ink lines and it is best not to overprint. Secondly, the dryness and viscosity of the metal ink should be controlled.
6.The color of the bag on the surface of the stacked or packaged bag will transfer to the back of another bag (printed or unprinted). This phenomenon only occurs in purple or rare colors. This is usually related to the storage environment and the performance of the ink itself. The main reason for this phenomenon is color penetration, which means that when using ink of this color for printing, the printed product will be affected by certain time, pressure, or other special circumstances. In terms of these products, flexible packaging companies should fully understand the packaging form and requirements of the product, choose suitable ink for trial production, and confirm the ink that meets the product requirements before mass production.
