Analysis on stork drum silk printing technology and equipment

drum silk printing technology is more and more widely used in label and packaging printing markets that need high quality and good visual effects. Using drum silk printing technology can achieve effects and other functions that other methods cannot achieve. The following takes the stoke cylinder silk printing machine as an example to introduce the cylinder silk printing technology and equipment

1. The roller printing system is composed of multiple independent monochrome printing units, which is suitable for printing of various widths and enables the synchronous production line to be under integrated intelligent control

the patented rotamesh wire technology is adopted in sto's roller printing system with an estimated sales volume of 75billion US dollars in the global safety and protection product market. It is a non-woven material made by electroforming in a small range by 100% nickel researchers. The unique hexagonal structure can achieve excellent stability, which can make the silk stretch freely in the paper roll printing with different width

rotamesh wire has the following characteristics:

① 100% metal nickel material

② non fabric

③ electroforming manufacturing

④ hexagonal structure ensures maximum stability

⑤ the wire joint is extremely flat and perfect

⑥ the smooth surface of the cylinder can reduce the wear of the printing plate

⑦ tapered hole has ideal inking performance

in addition, rotamesh wire is highly standardized and stable; Long service life, reusable, suitable for high-speed printing and high calibration accuracy

2. It can be seen that the silk oil filter stoke plate making system (RSI)

stoke cylinder silk system can provide a simple plate making system. Especially when short edition production or temporary printing is required, this system has completely independent, complete plate making quality and great flexibility. Because the system is installed indoors, its overall cost can even be reduced to the same level as the existing printing form

rotamesh silk plate making process is as follows:

1 End ring connection. The left and right end rings of the welded cylindrical wire are bonded to the cylinder with adhesive

2. Degrease. The silk is degreased before being coated with photosensitive adhesive

3. Coating. Apply a layer of stork water-based photosensitive emulsion on the surface of the drum wire, and the coating shall be uniform, flat and smooth

4. dry. The silk drum which has been degreased and coated with photosensitive glue is dried in a dryer

5. Exposure. After the silk coated with photosensitive emulsion is closely combined with the graphic film, it is exposed on the exposure device

6. development. Rinse the unexposed emulsion in the picture and text with water

7. testing. Check the quality of the plate before printing

8. Peel off the film

due to the unique photosensitive emulsion used in rotamesh process, the adhesive film on the plate can be easily removed with a special film remover and can be re coated. This brings a lot of convenience to short edition printing

cylinder silk printing system

cylinder silk printing is a printing technology with high economic and technical content. The key technologies in cylinder silk printing are plate cylinder and printing system

cylinder wire printing system:

1) the combination of stoke cylinder wire printing system dryer and 24 inch wide printing unit enables the production speed to reach 120 m/min. The roller printing machine has stable and durable structure, and the silk can be used repeatedly. It is suitable for printing products with large quantity or frequently repeated printing

2) the roller wire printing system generally has a simple and convenient moving parts conversion control system, and the downtime of replacement work is very short, which can press down the dent on the sample surface. The equipment can achieve high output

stoke cylinder wire printing system includes:

① independent drive and independent register wire unit (installed on various cylinder printing equipment)

② volume to volume equipment, and each unit is an independent system

③ roll to various post-processing equipment (such as sheet cutting, drum die cutting, etc.). (end)
