Digital direct-injection printing machine without coating

　　Digital Direct Printing MachineWhat is the free coating? How to avoid coating? What are the advantages? These three are difficult problems that plague new users. If the difference between them is not well understood, it is easy to cause a lot of trouble in the use of later equipment. Seriously, it may be a waste of money to buy equipment that is not available at all.

Coating-free UV flatbed printer means that when printing some raw materials, printing can be started without pre-printing the surface of the raw materials. It does not mean that all raw materials can avoid coating printing. This coating-free printing is conditional.

Anyone who does printing knows that printing some raw materials like glass, ceramic tiles, and metals cannot be directly printed. You need to do some coating treatment on the raw materials to print, so first of all, let's talk about the advantages of using coating:

1. Drying speed

The quick treatment fluid is made of special chemical materials, and it dries in about three minutes after spraying, especially on the more lubricious materials such as glass, porcelain, and metal.

If it is directly printed on some raw materials, it is mainly lubricating and non-absorbing materials, which has a poor effect, and the effect is special after using the treatment liquid. Regardless of whether the data is bent or folded or placed for an extended period of time, the data surface will not be cracked or faulted.

3. Wear-resistant and waterproof

Due to the adhesive component in the treatment liquid ingredients, the adsorption force of the ink and the raw material after printing is very superior, which is far more than the abrasion resistance of the untreated state, and the water resistance of the raw material after using the treatment liquid is also far superior. The coating state is multiple.

Customers who have used eco-solvent flatbed printers know that 90% of raw materials such as glass, ceramic tiles, metal, leather, etc. must be coated with this machine. Because eco-solvent inks directly print pictures, there is a great possibility that ink piles, poor printing and inkjet effects, etc. may occur.Digital printing equipmentIt is necessary to do the pre-printing treatment, which is the coating.
