Application of ink color matching in the production of Chocolate Paper Boxes

It is well known that in the industrial production of Chocolate Paper Boxes, printing is very important. It is directly related to the quality of the product. If the printing effect cannot achieve the expected effect or meet the customer's requirements, it may even cause huge losses. In the printing process, the restoration of colors is an important part, because many color box manufacturing industries use spot colors to express rich and bright colors, so the effect of spot color ink color matching directly affects printing production.

　　The traditional ink color matching is familiar to everyone, and there are many related experience introductions, so I won’t go into details here. Let’s talk about the help of computer color matching for ink color matching and color management.

　　The confusion of traditional color matching

The first color matching takes a long time and the number of tests is many. Traditional manual ink matching is used to judge the hue manually, then test, then manually display the sample, visually judge the gap, and then test again. This cycle takes a long time and the number of tests is too much, which is wasteful. lot of time.

　　 wasting ink

　　 Relying on human judgment, multiple tests are required. If 5 kg of ink is to be mixed, there may be 10 kg of ink remaining to be wasted after the ink is dispensed after many tests.

　　Ink inventory is large

　　The accumulation of remaining ink makes the stock of ink more and more, causing a serious burden.

　　The remaining ink utilization rate is low

　　 In the absence of a computer for color matching, the general manufacturer discards the remaining ink or mixes it into black ink, and the utilization rate is extremely low.

　　The advantages of computer color matching

The first color matching speed is faster, and there is no need to test many times. The first color matching speed is faster, and there is no need to test many times, because the computer calculates the light absorption and reflection characteristics of the ink to directly get the formula result. Generally, it only needs to be matched once and corrected once. The correct color can be obtained, while the traditional color matching requires constant experimentation and trial and error based on experience to obtain the ideal formula.

　　Avoid waste of ink

　　The ink needed for one color matching only needs about 30g, and the ideal formula can be obtained, so as to avoid the waste of ink due to repeated experimentation and continuous addition;

　　Because the proofer is used throughout the color matching process, only a very small amount of paper and ink can simulate the printing effect;

　　 color matching software can edit the cost of the ink, so that under the same color matching effect, it can prompt the color matcher to use a lower cost formula to mix the ink.

　　 Reduce ink inventory

　　Because the remaining ink is used to the greatest extent, the inventory will be greatly reduced, which saves space and also reduces the labor cost of remaining ink management, which brings convenience to production management. [next]

　　The remaining ink can be used to save costs in the next color matching

The use of surplus ink is a highlight of computer color matching. Traditional color matching mostly mixes surplus ink into gray ink or black ink for processing, which fails to fully utilize the surplus ink. The computer color matching system can utilize the remaining ink to the greatest extent. There are two ways, one is to use the remaining ink as a color type to establish a basic database to make full use; the other is to directly convert the current ink to waste ink if there is a surplus of the current ink during the computer formula calculation process It is very convenient to use with other colors next time.

　　 For replacing the substrate, the computer color matching system can find the formula faster and more accurately

The 　　 color matching system can give the corresponding color formula according to the spectroscopic curve of different substrates, which solves the annoyance of color matching after the actual printing substrate is changed.
