In China, certain requirements for chromatic aberration are: superior products – zero color difference is allowed; first-class products – no obvious differences are allowed; qualified products – allow for differences, but do not have an effect on the use. At present, domestic manufacturers aside from a few manufacturers basically implement the standard of first-class products.
From a scientific perspective
Products without chromatic aberration Original Wall paper cannot be produced, but only theoretically. Because the color of the wallpaper is not like paint or color, it is made up of monochrome, and the wallpaper is actually printed by multi-color, in fact it is all spot color printing, and each printed pattern is only expressed in a section of the final product or It is a little bit 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 definitely absolute. It really is a pseudoscience that will not recognize its presence, but it should be within the scope of acknowledgement. The degree of reputation varies and the results vary.
Light can cause color differences
According to experience, if the color difference of the wallpaper is in the case of backlighting or direct sunlight, the difference in color because of the difference in light reflection of the wallpaper will become reflected. Therefore, in a solid light or sunlight environment, try to make use of a wallpaper with wealthy printed patterns. Since the reflection of the pattern will go beyond the reflection of the chromatic aberration, the chromatic aberration could be well avoided.
Avoid chromatic aberration tips
Furthermore, if the simple wallpaper does not take light, you may use the technique of turning the top to effectively avoid chromatic aberration. If different batches of wallpapers are found in the same area, you can use the same batch of wallpapers on different wall space in order to avoid unnecessary trouble.
