As we all know, in the production of color box industry, printing is very important. He is directly related to the quality of the product. If the printing effect cannot reach the expected effect or meet the customer's requirements, it will even cause huge losses. In the printing process, color restoration is also an important part, because many color box manufacturing uses spot colors to express rich and vivid colors, so the effect of spot color ink matching directly affects printing production.
Everyone is familiar with the traditional ink color matching, and there are many related experience introductions, so I wo n’t go into details here. Let ’s talk about the help of computer color matching for ink color matching and color management.
Confusion of traditional color matching
The first color matching time is long, and the number of trials is more. Traditional manual ink matching judges the hue artificially, and then tests, then manually draws samples, visually judges the gap, and then tests again. This cycle takes a long time and the number of trials is relatively large, wasting lot of time.
The waste of ink is based on human judgment and requires multiple tests. If 5 kg of ink is to be dispensed, after multiple tests, 10 kg of ink may be wasted after the ink is dispensed.
Large amount of ink in stock The accumulation of surplus ink over time makes the amount of ink in stock more and more, causing a serious burden.
Low utilization rate of remaining ink In the case of no computer color matching, general manufacturers discard or mix the remaining ink into black ink, and the utilization rate is extremely low.
Advantages of computer color matching The first color matching speed is faster, there is no need to test many times The first color matching speed is faster, there is no need to test many times, because the calculation of the light absorption and reflection characteristics of the ink by the computer directly draws the formula results, generally only need to be matched once , Correct once to get the correct color, and traditional color matching requires continuous experiment and repeated trial and error to get the ideal formula.
To avoid wasting ink, the ink required for one color matching only needs about 30g to get the ideal formula, and avoid wasting ink by artificial experience and repeated addition;
Because the whole color matching process uses a proofer, only a 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 matchr can be prompted to use a lower cost formula to prepare the ink.
Reducing the ink inventory, because the surplus ink is utilized to the greatest extent, the inventory will be greatly reduced, which will save space, in addition, it can also reduce the labor cost of remaining ink management, which brings convenience to production management. [next]
You can use the remaining ink to achieve cost savings in the next color matching
The use of surplus ink is a highlight of computer color matching. Traditional color matching mostly uses surplus ink as gray ink or black ink for processing. It does not achieve the purpose of making full use of surplus ink, and computer color matching system can make full use of surplus ink. Generally There are two ways, one is to use the remaining ink as the color to establish a basic database to make full use of the other; the other is to calculate the formula in the computer, if the current ink is left, you can directly convert the current ink to waste ink It is very convenient to use it with other colors next time.
For replacing the substrate, the computer color matching system can find the formula more quickly and accurately. The color matching system can give the corresponding color formula according to the spectral curves of different substrates, which solves the annoyance of the color matching after the actual printing substrate changes.
