Several noteworthy points in the cost control of flexo ink

Stickers in China Most of the practitioners in the label industry have always had this kind of confusion: When you walk into the supermarket and look around, you can find that most high-end, beautiful stickers are combined with flexo or flexo. Printing related. Because the printing effect and quality stability are better than embossing, the development speed of flexo printing has shown double-digit growth in recent years, but it is far less developed than embossing. It can be seen that the development direction of China's label printing methods is different from that of Europe and the United States, and similar to Japan. The author believes that the main reason for this situation is the high cost of flexographic printing plates, inks and connecting die cutting tools and other important consumables. In recent years, web rotation In the field of offset printing and label printing, with the ultra-low plate cost, the combination of “web web offset printing + screen printing + die cutting” is the leading mode in short label printing, almost making embossing and flexo printing. Unexpectedly, it can be seen that the market competitiveness of flexo printing in the field of short single label printing is worrying. Faced with this situation, the reduction in flexo printing costs is undoubtedly the way to win greater development in the field of label printing.

In the cost of labeling, the cost of printing materials is the core part. Although the cost of ink does not account for the majority, it is no more than 10% at most, and less than 1% at a time. But from the total amount of its use, it is a small investment. The following article focuses on the ink link and discusses how to reduce the cost of flexo printing and the embossing by controlling the amount of flexo ink used. I hope to help the peers.

Consider the cost from the combined use of different types of inks

Flexo inks usually include water-based inks, UV inks, and solvent-based inks. Water-based ink is currently the most commonly used flexo ink; UV ink with its good stability, excellent operability, and low overall scrap rate make its relative cost lower, so the application speed grows very fast, especially in the absence of In the field of dry label printing, almost all of the UV inks are used; and solvent-based inks are used less and less in other applications besides being used more on satellite flexo presses. It can be seen that if the three flexo inks can be used differently or in combination, it will achieve a win-win situation in printing effect and cost control.

Considering costs from the perspective of product process design

The amount of ink used is usually determined by the size of the graphic area of ​​the label, and the size of the graphic area is designed by the customer, and the space that the label printing company can adjust is small. Therefore, a little "nail" spirit is needed to save costs.

1. Pay attention to the difference between two-layer ink printing and one layer ink printing

2. Determine if you need to glaze

Considering costs from ink adjustment

Here, let's not talk about the ink distribution system, nor the inventory management system, because this is a big project, and it tends to be more management. The central point here is how to control costs, so we only discuss how to adjust ink from a low-input level.

1. Accurate deployment before ink proofing

2. The right amount of ink before the proofing

3. Design or modification of the flexo ink disc

4. On-demand ink

Considering the cost of production from the machine

For production machines, the most important tasks are quality, throughput and wear and tear. Loss not only refers to the loss of the printing material, but also the loss of the ink.

1. Do not use additives easily

2. Avoid unnecessary ink waste

In summary, flexo printing can only have more competitive factors that affect the cost, including ink, in order to have stronger competitiveness. The advantage of flexo printing will not be dragged down by cost factors, so as to have a broader development space.
