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

China’s standards
In China, certain requirements for chromatic Stone paper Wall paper aberration are: superior products – zero color difference is allowed; first-class products – no apparent variations are allowed; qualified items – enable differences, but usually do not affect the use. At present, domestic manufacturers aside from a few manufacturers fundamentally implement the standard 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 place color printing, and each imprinted pattern is expressed in a area of the final item or It is a small amount 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 existence of chromatic aberration is usually absolute. It really is a pseudoscience that will not recognize its living, but it should be within the scope of recognition. The degree of recognition varies and the results vary.
Light could cause color differences
According to see, if the colour difference of the wallpaper is normally regarding 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 rich printed patterns. Because the reflection of the pattern will exceed the reflection of the chromatic aberration, the chromatic aberration could be well avoided.
Avoid chromatic aberration tips
In addition, if the basic wallpaper does not take light, you can use the technique of turning the head to effectively avoid chromatic aberration. If different batches of wallpapers are found in the same space, you may use the same batch of wallpapers on different wall space to avoid unnecessary trouble.
