Why the same barrel ink printing color is inconsistent
There are many reasons for the color change of the ink. Sometimes the ink formulation is different, which will result in different colors. Sometimes improper cleaning of the ink will cause the ink of the previous color to flow into the next color, which will result in uneven color. However, the printing machine often encounters the same barrel of ink and often has different color variations. What is going on?
Inconsistent printing colors will seriously affect the aesthetics of the product, causing customers to complain and return the carton factory. Generally speaking, there are two kinds of color changes when printing the same barrel of ink: First, the ink is always produced after being put on the machine, and the color changes; Second, the use of one barrel of ink changes several times. This article focuses on the first case!
First, the ink has been produced after the machine is on, which easily leads to changes in color.
In the production of large orders printing often appear, such as the production of Wahaha, unified instant noodles, Mengniu, Yili and other products, often the same ink will print a different color. These orders are very large, and each printing requires a long time of work. From the morning, the ink on the machine may be printed until the end of the afternoon. The color of this time period is fluctuating. When the printing was started, the color was normal. After 1.5 hours of printing, the color began to darken. At this time, the operator liked to add water to the ink to make the color lighter. After printing for another 1.5 hours, the color density of the color was lowered. In this way, the color of this batch will be very different.
Second, the improvement method: collect the production color data of the printing machine, sample, adjust the ink regularly
There are many ways to control the ink method, but in the production process, it is often seen that the color change is started before the ink color adjustment is started, instead of preventing the color change of the ink in advance. In order to make the same batch of orders and color production consistent, it is necessary to consider the factors of printing machinery. At this point, you need to collect the production color data of the printing press, take samples, and make appropriate intervals to adjust the ink! The specific steps are as follows:
1. Determine the appropriate speed: verify the color of the ink at the same viscosity, open the car at 80/min, 120/min, 160/min, then sample the three colors to see if the color is different. . For example, if the color is stable at 120 sheets/min, then the speed can be set to about 120 sheets/min.
2. Inspect the ink and determine the appropriate adjustment time: the speed of the ink in the same barrel is controlled at 120-130 sheets/min. The viscosity of the ink is monitored, the color samples are taken every 15 minutes, and the color samples are evenly distributed after 4 hours of production. , to see the degree of color change. If the color starts to change every 50 minutes, then it takes about 40 minutes to start the ink adjustment.
3. After finishing the above two items, taking the intermediate numbers for production monitoring will ensure that the colors are consistent.
Third, make reasonable adjustment according to the characteristics of the factory equipment
Because each device has a different structure and the anilox roll process is different, the printed colors are different. Therefore, it is necessary to make reasonable use according to the equipment of the factory to achieve the intended purpose. Controlling color is not just about understanding the use of ink, but also about the use of equipment. In the production operation, in order to achieve the best printing results, it is necessary to establish standard operating rules, which is the direction of enterprise development.
