In practical verification of pigment nanocrystallization, the color appearance of nanometer pigments is far darker than that of submicron pigments. The main reason is that the particles of the pigments are large and the light will break through, and the light will scatter and emit light. Light penetrates through. The nanopigment has a small particle size, weak light scattering, a small spectral absorption area, and a light reflectance of less than 1%, so the appearance of the color is significantly deeper than the submicron pigment. Nano-pigmented pigments have a wide range of applications, such as ink-jet inks, coatings, inks, and optoelectronic displays. In the manufacturing process of products, the addition of 3% to 5% of nanopigment to improve the ink Shading rate, saturation, anti-rotation, water resistance and other issues. In addition, in ordinary and color laser printers, the thickness of the toner particles is an important factor that determines the quality of the output, and it is also a key to whether the resolution of the printer can be further improved. Therefore, using nanomaterials to make carbon powder for laser printing, especially color laser printing, can greatly improve the quality of the output. In addition, in the current color ink-jet printing, due to the ink problem, not only the print quality is affected, but also the occurrence of nozzle clogging and other failures from time to time, but once the nano-material ink is developed, it is believed that these problems can be well resolved. In addition, color laser printing and color inkjet printing are the major printing devices for future digital printing and on-demand printing. Nanotechnology will play an important role in this field.

Second, nano UV coating oil

Paper packaging products, surface gloss processing technology is gradually developed to the direction of UV curing UV coating, nano-UV polishing oil to color corrugated box with resistance to friction, scratch resistance, moisture, high gloss and other properties. Nano-UV coating oil is mainly composed of nano-oligomer (such as epoxy-acrylic acid, etc.), reactive diluent, photoinitiator and other additives. There are many methods for UV coating, such as coating and printing, and roller coating.

It can be expected that when the ever-improving nano-high-tech is widely used in corrugated box printing, the printing of corrugated boxes will have higher resolution and better results. The manufacture of corrugated boxes is inseparable from the packaging and printing. Nanoparticles play an increasingly important role in the packaging and printing industry.
