How to identify the color difference of the wallpaper? ? ?

China’s standards
In China, certain requirements for chromatic 3D Wall paper aberration are: superior products – no color difference is allowed; first-class products – no obvious variations are allowed; qualified products – allow for differences, but do not affect the use. At present, domestic manufacturers aside from a few manufacturers fundamentally implement the typical of first-class products.
From a scientific perspective
Items without chromatic aberration can’t be produced, but only theoretically. As the color of the wallpaper is not like paint or paint, it is made up of monochrome, and the wallpaper is basically printed by multi-color, in fact it is all place color printing, and each published pattern is only expressed in a part of the final product or It is a little bit of stars in all areas. Unlike paints or paints, the color difference meter can be used to measure its color difference, which can be represented by data. The living of chromatic aberration is usually absolute. It really is a pseudoscience that will not recognize its existence, but it must be within the scope of reputation. The degree of recognition varies and the outcomes vary.
Light can cause color differences
According to see, if the color difference of the wallpaper is definitely in the case of backlighting or direct sunlight, the difference in color due to the difference in light reflection of the wallpaper will become reflected. Therefore, in a strong light or sunlight environment, try to use a wallpaper with rich printed patterns. Because the reflection of the design will go beyond the reflection of the chromatic aberration, the chromatic aberration can be well avoided.
Avoid chromatic aberration tips
In addition, if the simple wallpaper will not take light, you may use the method of turning the head to effectively avoid chromatic aberration. If different batches of wallpapers are found in the same space, you can use the same batch of wallpapers on different walls in order to avoid unnecessary trouble.
