How to conduct gloss test on glazing samples

what will you think of immediately when you consider glazing? It is almost certain that the first is to use the direction key to move the focus to the position to be corrected and press the OK key to enter the smooth finish of the state. This is also our answer. This naturally raises a question: what is gloss? At the emotional level, we associate this term with positive emotions. Gloss represents clarity, purity and elegance. In short, it is something special. Adjust the pointer of the dial indicator at zero. Scientifically speaking, gloss is a physical property, which is defined as the ability of a material to basically reflect incident light in the direction of mirror reflection. Therefore, gloss is an optical feature that can be derived from the roughness or smoothness of a surface

in the printing process, every possible finishing technology is used to realize the bright impact effect and establish the highlight. The previous samples illustrate some of the most numerous possibilities of the illustrated method. We hope these samples have aroused your interest. You may have found some new ways to impress your customers. In fact, this is what makes us most happy

in order to help you make a decision and help you determine the technology, material combination and embossing roller that are most suitable for your live parts, we have printed and polished a series of samples with the most common substrate, ink and polishing oil. Our goal is not to achieve the highest gloss level possible, but to produce reliable, stable and reproducible glazing samples

the selection of wrinkle roller is very important to the glazing result. In order to get the required gloss, the image and absorption of the carving must be consistent with the type of substrate used in the selected glazing oil. Gloss intensity will be measured with a so-called glossometer (reflectometer) at a certain angle of incidence and reflection of light. ISO 2813 (DIN 67530) stipulates that the high gloss surface is 20/20, the standard surface is 60/60, and the matt surface is 85/85. For many years, the two ends of the sample in the printing and packaging industry have been clamped. I always like to use 45/45 and sometimes 60/60 to check the polished prints. Therefore, in order to obtain a true contrast of gloss level, it is often necessary to specify the applicable measurement angle

however, due to certain gloss loss (gloss loss effect) after printing, the measurement on the printed sheet just printed and polished will not yield real measurement results. Therefore, in order to determine the gloss level more accurately, gaobao has developed a special gloss test plate. When used correctly, it can provide a value to determine the degree of gloss loss at the time of development, and provide an actual gloss level for actual production. Do you want to know more
