Plastic boxes of raw materials PVC, PTE, PP performance determines the quality of the printing ink, plastic box factory in Dongguan seems only good performance materials, in order to get better prints coloring effect. Therefore, a correct understanding of the relationship between coloring and printing performance plastic box, according to the printed product, the characteristics of the process conditions, a reasonable choice for printing high-quality raw materials, to improve the quality of products has important practical significance.
　　 1, the relationship between the degree of smoothness of the plastic box with the coloring effect of smoothing is to evaluate the degree of surface irregularity plastic box technical indicators, is a plastic box surface is flat, smooth and uniform level of physical, that is, under certain vacuum conditions so that a certain volume air from the surface of the test sample between the plastic boxes under pressure and the flow through the smooth glass surface to measure the time required, the unit expressed in seconds. The higher the number of seconds plastic box smoothness better. Plastic box smoothness better contact between the surface and the printing plate, the more uniform and complete layout (letterpress) or ink transfer on the more fully blanket, printing coloring effect is better. Conversely, poor smoothness raw plastic boxes, ink transfer uneven, inadequate, and the raw surface on the amount of ink permeability, the coloring effect is poor, and tend to make printing ink blur, light hair. So, fine printing products, network cable finer, smaller diameter outlets, should be used more smoothness good plastic box printed materials, so as to make the original good reproducibility.
　　2, the relationship between the plastic box gloss and coloring effects
Plastic box factory in Dongguan plastic box analysis refers to the specular gloss level of the surface of the plastic box , expressed as a percentage . The higher the gloss plastic boxes , the more it can be like a mirror -like surface reflecting light , the more it can show the appearance of the characteristic bright . In fact , plastic boxes in addition to the specular surface , but also the existence of diffuse, so that the gloss plastic box drop . High-gloss plastic boxes of raw materials , the more vivid printing ink , ink visual effect is good. We can say that the smoother the plastic box of raw materials , the higher the gloss , gloss, color printing is also higher. Gloss and smoothness of the plastic box of raw materials is closely related , but not the smoothness of gloss , plastic boxes raw shiny surface , is not necessarily a smooth surface. Features gloss plastic box from the raw materials , the plastic box factory in Dongguan plastic box to choose the right materials for printing according to the characteristics of printed materials , very practical significance. If the layout of text books and text-based , should use the general gloss paper , in order to avoid reflections , the eye for a long time to see that does not produce fatigue. The printing plates based in layout should use high-gloss PVC, PET, PP material , so that printing ink evenly , thick , bright eye.
