Analysis of Factors Affecting UV Printing Quality

4.PET Polyethylene terephthalate (polyester)

The Chinese name is polyethylene terephthalate (polyester). Its material properties are low specific gravity, no moisture absorption, good insulation, transparency, low cost, and low rigidity.

5. ABS (acrylonitrile-butadiene-styrene tri-copolymer)

The Chinese name is acrylonitrile-butadiene-styrene tri-copolymer. Material characteristics are the proportion of each polymer, ABS with different characteristics, surface strength and heat resistance are all excellent, surface gloss is good, surface coating and plating is good, hygroscopicity, general finished products can be dyed by Need color. Its related printing products suitcase plate, ABS tube, home appliance shell.

6.PC (polycarbonate)

The Chinese name is polycarbonate. Its material properties are good transparency, high impact resistance at room temperature, high temperature resistance, high rigidity, FDA grade, poor abrasion resistance, and poor chemical resistance. Its related printing products include safety glass and transparent containers for medical equipment.

Synthetic paper

Synthetic paper has two definitions, as follows:

(1) Synthetic resins (PE, PP, PS, and PVC) are used as the main raw materials, paper properties are imparted through the processing of paper-like paper, and paper properties are used.

(2) A synthetic resin is used as the main raw material to produce a paper whose appearance is similar to that of paper made of pulp, and whose physical properties are intermediate between a paper of Pulp Paper and a plastic film.

The best paper properties of synthetic papers are filled and stretched film types. Its characteristics are mainly derived from the paper layer. Fine voids or microvoids can be formed in the center of the relevant filler particles. The realization of the existence of). Although these microvoids are evenly distributed or uniformly dispersed in the thickness direction of the paper layer, those on the outer surface and its vicinity are in communication with the outer edge area of ​​the paper layer, thus forming a cracked surface in the paper layer. The interconnected state of the outer edges of the above-mentioned voids, even the exposed state of the filler particles, are all derived from the stretching of the film containing fine filler particles. Because of this feature, this type of synthetic paper is intrinsically provided with a good printability or ink receptability (or ink receptivity) and ink drying characteristics are enhanced.

If these general good print aptitudes can be further improved, and if Ink adhesion in particular can be extended to a larger range, the practical use of synthetic papers will increase again.

Because synthetic paper can be used in situations where traditional paper cannot be used effectively, proper ink formulations are extremely important for both image quality and end-use durability.
