In the field of self-adhesive printing, the discussion about intermittent machines and full-rotary machines has been protracted. I will make the following analysis to share with you:

Intermittent semi-rotary machines using circular flattening technology Type trademark machine is another improvement in equipment in the history of trademark machines. Its printing quality is better than that of the oblique press label machine. However, the satellite-type high-speed all-rotary trademark machine developed in a short period of time suppressed its halo. The rotary trademark machine adopts a circular pressing process, and its process principle is basically the same as that of offset printing, making its printing quality comparable to that of offset printing. The label machine uses roll materials, and the self-adhesive trademarks and labels printed and produced can use automatic labeling machines to fully automatically affix labels to the products, which has led to the rapid development of the label machine market.

1. Direction of public opinion: As the saying goes, a lie will become truth if it is spread a hundred times. Nowadays, the domestic label market is crowded with players. According to statistics, there are as many as two dozen intermittent machine suppliers, with about six in total. Seven families. In this way, with the advertising and publicity of intermittent machine manufacturers, the advantages of intermittent machines, such as not changing the plate cylinder and saving plate materials, have flooded the market, making all-rotation machines "lost" in the market. Based on years of understanding of the label market and machines, the author believes that this guidance is biased.

2. The mainstream of label printing in the world: First of all, European and American countries mainly use flexographic printing, and this type of machine completes about 80% of the printing volume. And the flexographic printing machine is absolutely full rotation;

3. Printing process: Intermittent type can currently only realize round press round UV printing, which improves the printing effect, but it is difficult to achieve multi-functional online printing process: such as common Glue removal (wet wipes), back printing, cold foiling, oiling, multi-layer lamination, online hob die cutting, etc.; these are the basic functions of the full rotation. Satellite full rotation also has many special feeding methods, allowing it to achieve more special processes;

4. Speed ??and efficiency: First of all, let’s state a concept. Intermittent manufacturers often promote that they can achieve full There are two modes: rotary and intermittent, but please note that it is only possible when a specific plate length is met, that is, when the machine plate cylinder circumference is met. Usually the speed of satellite machines is 3-5 times that of intermittent machines.

5. Adjustment loss: Both machines use adjustment materials for proofreading. Usually, the satellite type can be used on both sides of writing paper and coated paper without glue, while most of them use self-adhesive reciprocating intermittently. , please note that after a few uses, the self-adhesive may not be usable due to uneven paper edges, because the intermittent machine is most afraid of uneven paper edges, which will affect overprinting. The adjustment materials of the satellite machine can be used back and forth up to ten or twenty times.

6. Material suitability: Due to different structures, intermittent machines have very high requirements for material slitting. Poor slitting directly affects overprinting, and the material is required to have good tensile strength, so that It greatly limits the ability to receive orders; while the satellite type is covered by the central drum, which improves the stability of the material during printing, allowing it to have excellent adaptability to printing materials, such as common toothpaste sheets, PVC films, etc. . Usually satellite machines can print films as thin as 4um.

Objectively speaking, the biggest advantage of the intermittent method is that it saves printing fees and is suitable for small orders. I personally think that it is a replacement product of the traditional flattening machine. It is inferior to the all-wheel turning machine in terms of cost performance and order-taking capabilities. As we have seen, label printing is developing in the direction of multi-color, special material application, multi-process, anti-counterfeiting, etc. Choosing satellite full-rotation will be a wiser choice. Losing competitiveness in order to save a little publishing fee is not worth the gain.
