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

China’s standards
In China, certain requirements for chromatic aberration are: superior products – no color difference is allowed; first-class products – no obvious variations are allowed; qualified items – allow for differences, but do not impact the make use of. At present, domestic manufacturers except for a few manufacturers essentially implement the standard of first-class products.
From a scientific perspective
Items without chromatic aberration cannot be produced, but only theoretically. As the color of the Pure paper Wall covering wallpaper is not like paint or color, it is produced up of monochrome, and the wallpaper is actually printed by multi-color, and it is all place color printing, and each imprinted pattern is only expressed in a area of the final item or It is a small amount of stars in every areas. Unlike paints or paints, the color difference meter can be used to measure its color difference, which may be represented by data. The living of chromatic aberration is usually absolute. It really is a pseudoscience that does not recognize its presence, but it must be within the scope of recognition. The degree of reputation varies and the outcomes vary.
Light could cause color differences

Therefore, in a strong light or direct sunlight environment, try to use a wallpaper with wealthy printed patterns. Since the reflection of the pattern will exceed the reflection of the chromatic aberration, the chromatic aberration can be well avoided.

If different batches of wallpapers are used in the same room, you may use the same batch of wallpapers on different wall space in order to avoid unnecessary trouble.
