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

China’s standards
In China, certain requirements for chromatic aberration are: superior products – zero color difference is PVC Wallcovering allowed; first-class products – no obvious differences are allowed; qualified products – allow for differences, but usually do not affect the use. At present, domestic manufacturers except for a few manufacturers fundamentally implement the typical of first-class products.
From a scientific perspective
Products without chromatic aberration cannot be produced, but only theoretically. As the color of the wallpaper is not like paint or paint, it is produced up of monochrome, and the wallpaper is basically printed by multi-color, and it is all spot color printing, and each printed pattern is only expressed in a section of the final item or It is a small amount of stars in every areas. Unlike paints or paints, the colour difference meter can be utilized to measure its color difference, which may be represented by data. The existence of chromatic aberration is usually absolute. It is a pseudoscience that does not recognize its presence, but it should be within the scope of reputation. The degree of acknowledgement varies and the results vary.
Light can cause color differences
According to see, if the color difference of the wallpaper is in the case of backlighting or direct sunlight, the difference in color due to the difference in light reflection of the wallpaper will be reflected. Therefore, in a solid light or sunlight environment, try to use a wallpaper with rich printed patterns. Because the reflection of the pattern will surpass the reflection of the chromatic aberration, the chromatic aberration can be well avoided.
Avoid chromatic aberration tips
Furthermore, if the plain wallpaper will not take light, you can use the method of turning the head to effectively avoid chromatic aberration. If different batches of wallpapers are used in the same room, you may use the same batch of wallpapers on different walls to avoid unnecessary trouble.
