Due to uncontrollable factors, seamless wallcoverings as textiles will inevitably suffer from chromatic aberration problems. Today, let's take a look at the reasons for the color difference of wallcoverings. How can we solve it?
1、Color difference of natural materials
The chromatic aberration of natural materials is common in furniture, tiles, flooring and other industries. Similarly, if the wallcovering is made of natural materials, such as paper weaving, pulp fiber, etc., because of the color difference caused by the difference of the natural material itself, this situation cannot be avoided by anyone. It is precisely because of this that the natural beauty of natural materials is even more apparent.
Solution: When choosing wallcoverings, be sure to understand the material of the wallcoverings in advance, and be mentally prepared for the color difference of the wallcoverings. If you are a soft decoration design or wallcovering specialty store, you should also explain clearly to the customer when designing, matching and selling. If the customer can accept such color difference, the customer complaints will be reduced a lot later, which will also add points to your service!
2、Color difference between different batches
1) Changes in temperature, humidity and formula errors in the production process will lead to color changes in the produced products.
2) The thickness, density and water absorption of the cloth base are slightly different, which will also lead to different degrees of adhesion of the printing and dyeing pigments, resulting in the problem of chromatic aberration.
3) There is a slight difference in the pressure at both ends of the roller during printing, which may cause the color difference at both ends of the same roll of wallcovering.
4) Different batches of wallcovering production, such as production shift, raw material replacement and equipment maintenance, will affect the consistency of product color.
5) Factors such as the time of product production (oxidation degree), sunlight exposure (the influence of ultraviolet rays) and other factors may also lead to differences in color.
Solution: Yarn-dyed fabric refers to weaving yarn or filament after dyeing. Choosing such products will greatly reduce the obvious color difference, or choose to buy products from big brands to reduce the occurrence of problems. If it is a partitioned wallcovering product, you must do a color comparison before construction, and then paste it on the wall after it is relatively consistent.
3、Color difference caused by improper construction
The wallcovering is polluted by glue and other foreign objects during the pasting process to form a color difference; the uneven strength of the tools used when pasting the wallcovering causes the glue to penetrate and overflow, resulting in color difference; the phenomenon of alkali return can also cause local color difference.
Solution: Before construction, we must pay attention to the wall treatment, paint the wall base film, effectively fasten the wall, isolate the wall and the wallcovering, and prevent mildew, moisture and alkali. When it is polluted by foreign objects such as glue, it should be scrubbed and cleaned in time. The construction must be done step by step. Standardized wallcovering construction is very important. Finally, the selection of good auxiliary products is also the key to avoiding the problem of color difference in the later stage.
4、Color difference caused by other factors
1) Different lighting
The difference of light and shade in the indoor light will affect the entire visual sense, and then affect the color change of the wallcovering, resulting in color difference.
2) Different angles
Different positions of the wallcovering, light refraction Angle is different.
3) Different light sources
Different light sources reflect different colors. For example, the wallcovering after paving does not see any problem in natural light, but when the curtains are drawn and the downlights or spotlights are turned on, there may be very obvious color differences.
4) Mood influence
Different people have different moods, which will produce different color differences. Generally, the judgment standard is made by people's feelings, and even the same person will have different subjective differences in different time periods.
The solution:In the relevant acceptance standards of the country, the premise of acceptance is "face up to" -- use positive observation to see whether there is an obvious color difference problem in the wallcovering. Also is to see the value of color difference, color swatches of color difference is very obvious, generally the ABL three values, representing the red, green, yellow/blue/black and white, only the color difference value within a certain range in order to be qualified, because the chromatic meter test results related to operating environment, methods, and so have such situation: there are two products the eyes color almost there, but the color difference value; The two products seem to have color difference, but the color difference meter test result is qualified.
Although the color difference of the wallcovering is inevitable, the probability of occurrence is generally very small. Well, the dry goods about the color difference of wallcoverings are here today~
