Almost all printing processes seek to firmly adhere the fluid ink to the surface of the product without falling off. Since the ink is composed of pigments, binders, various additives and solvents, it is necessary to take measures to shorten the adhesion time and drying of the ink. Time is an inevitable requirement of the printing process.
The screen printing ink used in the screen printing process belongs to the leakage type ink, which can be squeezed through the blank part of the screen to form an imprint under the action of pressure. In the drying process, in addition to the natural drying and natural volatilization process, the temperature is forced Drying will speed up the drying process of the ink.
There are many kinds of screen printing inks, but the most important screen printing inks are basically solvent-based inks and UV inks. Solvent-based inks are mainly characterized by the complete volatilization of solvents, while UV inks are mainly based on the crosslinking reaction of acrylic resins under UV light irradiation. feature.
The forced drying of solvent-based inks generally uses a far-infrared tunnel furnace. This is a machine that can continuously generate heat and accelerate solvent volatilization. It is used in conjunction with a screen printing machine. Automatically enter the drying unit and receive heat radiation. Tunnel furnaces are widely used in post-printing processes such as pad printing and silk screen printing.
Similarly, the drying of UV ink must use a UV curing machine. The UV curing machine is a device that generates UV light. The metal halide lamp installed in it emits ultraviolet light after being lit. When a product printed with UV ink passes by, the ink will instantly Dry on product surface.

Application︰
In the printing process, the process of the final drying of the ink to the printed matter is very important. We have a variety of means to accelerate the drying of the ink. For example, solvent-based inks can be dried by a tunnel drying oven, and UV inks can be dried by a UV curing machine. dry. The tunnel drying oven uses a heating tube to generate infrared rays. The infrared rays irradiate the surface of the ink to cause the volatilization of the solvent and the curing of the connecting material. This drying method is very common in pad printing, silk screen printing, especially textile printing. The principle of the tunnel oven dryer is simple, and the structure is not complicated. It has a significant printing and drying effect for plastic printing, toys, gifts, handicrafts and even daily necessities.
