It is well known that in the production of color box industry, this part of printing is very important. He is directly related to the quality of the product. If the printing effect can not achieve the expected effect or meet the requirements of customers, it will even cause huge losses. The reduction of color in the printing process is an important part, because many color box manufacturing uses spot colors to express rich and vivid colors, so the effect of spot color ink color matching directly affects printing production.
Traditional ink color matching is familiar to everyone, and there are many related experiences. I won't go into details here. Let's talk about the application of computer color matching to ink color matching and color management.
Traditional color matching puzzle
The first color matching time is long, the number of trials is more than traditional artificial ink distribution, and the hue is judged by humans. Then, the test is performed, and then the sample is manually sampled, the gap is visually judged, and then the test is performed. This cycle takes a long time and the number of tests is also too much. lot of time.
Wasted ink relies on human judgment and requires multiple tests. If you want to dispense 5 kg of ink, after several tests, there may be 10 kg of ink remaining waste after the ink is dispensed.
The large amount of stock ink and the accumulated ink of the remaining ink make the amount of stock ink larger and larger, causing a serious burden.
The remaining ink utilization rate is low. In the case of no computer color matching, the general manufacturer discards or mixes the remaining ink into black ink, and the utilization rate is extremely low.
Advantages of computer color matching For the first time, the color matching speed is faster. It is not necessary to test many times. The first color matching speed is faster. It is not necessary to test many times. Because the computer calculates the light absorption and reflection characteristics according to the ink, the formula result is directly obtained. Generally, it only needs to be matched once. Correct the color to get the correct color, while the traditional color matching requires constant experimentation and repeated trials to get the ideal formula.
To avoid the waste of ink, the ink required for one color matching only needs about 30g, which can get the ideal formula, avoiding the waste of ink by human experience and repeated testing;
Because the entire color matching process uses a proofer, only a very small amount of paper and ink can simulate the printing effect;
The color matching software can edit the cost of the ink, so that under the same color matching effect, the color matching person can be prompted to use the lower cost formula to formulate the ink.
Reducing ink inventory Because the maximum use of the remaining ink, the inventory will be greatly reduced, to save space, in addition to reduce the labor costs of residual ink management, to bring convenience to production management. [next]
Can use the remaining ink to achieve cost savings in the next color matching
The use of the remaining ink is a highlight of computer color matching. Most of the traditional color matching is to dispose the remaining ink into gray ink or black ink, which does not achieve the purpose of making full use of the remaining ink, and the computer color matching system can make the most use of the remaining ink. In two ways, one is to use the previous remaining ink as a color database to build the basic database to make full use of the other; the other is in the computer computing recipe process, if the current ink has remaining, you can directly convert the current ink into waste ink It is very convenient for the next time to use other colors.
For the replacement of the substrate, the computer color matching system can find the formula color matching system faster and more accurately. The corresponding color formula can be given according to the spectrogram of different substrates, which solves the annoyance caused by the actual printing substrate after changing the color.
