In order to avoid light pollution, many writing papers choose matte paper. In order to ensure that the gloss of the matte paper is within a reasonable range, we can use a gloss meter to detect it.
The so-called matte paper is relative to the polished paper, and its surface has a certain rough feeling. When the light is irradiated on the surface of the matte paper, diffuse reflection will occur, and the gloss is soft and non-glare. Matte paper has a very good printing effect on the inside pages of color books. The surface of matte paper is very smooth. The glossy paper will increase with the rise of smoothness, but the change is not higher than that. When the paper is relatively rough, the gloss is slightly increased. With the increase of smoothness, when the size of the rough groove on the paper surface is in the visible wavelength range, the gloss will become obvious. And the matte paper coating degree is grasped before this critical point, so that the paper's flatness is very good and the gloss is relatively small.
Matt, also known as matte, is matte as opposed to flat, which is a non-glossy surface. Light pollution can be avoided and maintenance is more convenient. The matte surface is a bit hairy, like the surface of frosted glass.
1. In terms of feeling: matte gives a softer feeling and is more intimate; high light gives a cold feeling and is taller.
2. In terms of chroma and brightness: matte colors will be relatively lighter and darker; highlight colors will be darker and brightness will be much higher.
3. In terms of touch, matte warmth will be stronger; highlights will be colder.
Generally speaking, the matte gloss is below 20GU, the semi-matt gloss is between 20-40GU, and the gloss gloss is above 40GU. The specific gloss of matte paper can be measured using the Linshang LS192 gloss meter.
For the gloss measurement of matte paper, a general gloss meter with an angle of 60 degrees is generally used. In the measurement process, the size of gloss and uniformity of gloss are two important indicators that matte paper needs to pay attention to. The uniformity of gloss of matte paper requires gloss. The instrument has statistical functions, maximum, minimum, average and standard. deviation.
One of the indispensable steps after the gloss of paper prints is the gloss test. After the gloss of paper prints is processed in various ways, is the gloss acceptable? At this time, a gloss meter must be used, and Linshang LS192 gloss meter is the best choice for measuring the gloss of printed paper, especially matte paper. In addition, whether it is rough sketch paper or smooth cover paper, it can be easily measured using the LS192 gloss meter. The LS192 gloss meter uses a 60-degree measurement angle. It is a general-purpose instrument with a large range of 0-1000GU. Multi-point measurement will calculate the maximum, minimum, average, mean square error and real-time values in real time. The smaller the difference, the more uniform the matte paper surface.
