The biggest effect of color correction on the product is to make the color of each product consistent. Generally, it is appropriate to spray four times for flat work products (such as countertops, doorways, etc.). The color requirements of the side and front should be consistent. The products on the opposite side (such as dining chairs and cabinets) should be sprayed on the areas that are not easy to spray. After the spraying operation of each product is completed, the swatches need to be compared, and the colors can be handed over after the same color.
