China’s standards
In China, certain requirements for chromatic Classic Wallpapers aberration are: superior products – no color difference is allowed; first-class products – no apparent variations are allowed; qualified products – allow for differences, but do not impact the use. At present, domestic manufacturers except for a few manufacturers fundamentally implement the standard of first-class products.
From a scientific perspective
Items without chromatic aberration cannot be produced, but only theoretically. Because 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, in fact it is all place color printing, and each imprinted pattern is only expressed in a area of the final product or It is a little bit of stars in every areas. Unlike paints or paints, the colour difference meter can be used to measure its color difference, which can be represented by data. The existence of chromatic aberration is normally absolute. It is a pseudoscience that will not recognize its existence, but it must be within the scope of recognition. 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 definitely in the case of backlighting or sunlight, the difference in color because of the difference in light reflection of the wallpaper will be reflected. Therefore, in a strong light or sunlight environment, try to use a wallpaper with wealthy printed patterns. Since the reflection of the pattern will surpass the reflection of the chromatic aberration, the chromatic aberration could be well avoided.

If different batches of wallpapers are used in the same area, you can use the same batch of wallpapers on different walls in order to avoid unnecessary trouble.
