3. Low energy consumption and high production efficiency Flexo printing equipment usually uses reel type materials, the width can be as narrow as 2.5 cm, width to several meters; multi-color printing from double-sided to coating, laminating, hot stamping, die cutting , Discard, rewind, or cut and other processes are completed one at a time. Therefore, the flexographic printing method can greatly shorten the printing cycle, reduce energy consumption, and reduce costs, allowing users to occupy an advantage in a highly competitive market.

4. Easy to operate and repair The structure of the flexographic printing press is relatively simple compared with other printing machines, so it is easy to operate and easy to maintain.

5. Low loss, short cycle, high efficiency Printing cost Flexo printing is 15% lower than offset printing; paper consumption, flexographic printing paper rejection rate is 1%; and offset printing is 5%; In addition, flexographic printing press sets printing, molding Cutting, polishing and other functions in one machine, corrugated box production process than offset printing 2-3, and offset printing machine also need to be equipped with back machine, die-cutting machine, polishing machine and other equipment, increased investment; printing Cycle: The amount of work completed in 2-3 days for flexo printing, and offset printing takes 7-8 days to complete, greatly shortening the production cycle, reducing production costs and increasing economic benefits.

6. The noise is small and the non-polluting flexographic printing press has a simple structure, and the noise of the transmission mechanism is small; the use of water quality ink has no pollution to the environment.

7. There is no ink flying phenomenon. Because the use of water quality ink for flexographic printing does not pollute the environment, and with a reverse squeegee, it will not produce ink flying. After printing, the surface of the box will not fade, and will not deink.

8. Good cardboard stiffness, strong compressive bearing pressure Due to the use of corrugated cardboard for flexographic printing, after high temperature processing and hot glue bonding, the compressive strength is significantly better than that of offset cold glue compound, and the surface of the carton is UV varnish, which is resistant to abrasion. Dirty, moisture-proof function.

Although the flexographic printing press has a simpler structure than offset printing, there are many variations involved in flexo printing. Plates, anilox rollers, inks, embossing structures, printing rollers, etc. influence and restrict each other throughout the flexographic printing process. Therefore, flexographic printing is a technology with a high technological content. The practitioner must master the relevant knowledge from the pre-press plate making process to the printing process.

In addition, as a relatively mature printing process, offset printing and gravure printing have already been followed by some recognized or nationally-developed standard specifications throughout the entire process. During flexographic printing, there are no universal guidelines, parameters, or guidelines to guide flexographic printing throughout the process, thus creating a situation where the quality of flexographic printing is difficult to control.

Comparison between flexographic preprinting and gravure preprinting

Flexographic off-line preprinting separates printing from traditional preprinting and corrugated production lines, so that printing and corrugating are not carried out on the same production line, radically changing the situation in which some printing companies do not have large production orders. The high cost of printing, low efficiency and other shortcomings. Wells can make appropriate improvements based on the customer's original corrugated production line to reduce the customer's repeated investment, so that the customer can perform off-line pre-printing by adding flexographic printing and auxiliary equipment.

1. Less equipment investment Previous flexo printing equipment was mostly from abroad, and it was expensive. If you import a set of 8-color 1.5-meter-wide printing presses, you must invest at least 20 million yuan. Now invest in a set of “Cos High” flexographic off-line pre-printing equipment which only accounts for 10%-15% of the investment cost of imported equipment. It is more suitable to use domestic raw materials (ink, paper, etc.) while maintaining the same printing quality. The maintenance is more convenient and the cost is greatly reduced.

2. Good environmental protection Gravure generally uses solvent dilution inks. Not only is there a lot of solvent volatilization in the production process, but it also consumes 1-2 times more power than flexo printing to dry. A slight residue of the printing solvent will produce odors, resulting in waste products. Defective goods. The flexographic printing adopts water-based ink that meets international environmental protection requirements, so that no pollution is produced in the production process, and the qualified rate of the product is greatly improved. The plate-making adopts a non-volatile and environmentally-friendly solvent, and an environmentally-friendly solvent recovery device recovers the waste solvent, and the solvent is The pollution of nature is minimized.

3. High print quality We recommend using a 1.14mm thick plate for precision off-line preprinting, and normal production can reach 150 lines/inch. The printing on rough paper of paper can still achieve the desired effect. The printing quality can be comparable with offset printing and gravure printing, which can expand the printing adaptation range, greatly reduce the production cost, and directly print in corrugated paper (60 -110 lines/inch is a far cry from the world, and will not reduce the strength of the corrugated plates and produce ribs as the plates squeeze. Because the equipment is more humanized, it is easy to operate and easy to maintain. Operators do not need to step by step to achieve satisfactory printing results.

4. Flexographic off-line pre-printing Low cost flexo off-line preprinting Patterns are printed on face paper prior to corrugating, eliminating the need for extrusion of corrugated board, and the requirements for facing and core papers are greatly reduced; savings of up to 18% can be achieved - 22% of raw material costs; paperboard basis weight decreased by about 15%. The same material used for off-line pre-printing technology will achieve better results (usually printed on corrugated board can only reach 60-110 lines/inch, while flexographic off-line pre-printing can reach 150 lines/inch or even higher).

The gravure ink volume is 6-8 g/m2, the flexographic off-line preprinted ink volume is only 1/2 of the gravure, and the plate making fee is low (only 1/3 of the gravure), and the plate making time is only 1-2 hour. The gravure plate making time takes 2 weeks, and regardless of the size of the printing pattern, it is necessary to make a full-fledged version of the printing roller, how much the pattern of the off-line pre-printed flexographic printing plate is made, and the cost of the plate material is greatly saved.

5. To ensure the strength of the carton, the process is to print the rolled paper first and then enter the production line of the corrugated cardboard so that the production line of the corrugated cardboard will not be damaged, so that the corrugated cardboard will not be damaged and the compressive strength of the carton will be improved.

6. Chestnut off-line pre-printing high-efficiency printing efficiency off-line pre-printed paper made directly after the printing of corrugated cardboard, eliminating the crucible process, greatly increased production efficiency and reduce scrap rate.
