Product Description
Flexo Printing Machine or Letter Press Application:
Flexo Printing Machine or Letter Press  is using photosensitive resin soft version for the printing plates, commonly known as "anilin printing presses. " Suitable for printing polyethylene, polypropylene plastic bags, cellophane, Web and other packaging materials, food paper packaging, supermarket handbag, bag, garment bags and other packaging ideal printing equipment.

Flexo Printing Machine or Letter Press Performance:
1. Simple operation, soft start-up, color accurate.
2. Including meters can set printing quantity according to the requirements, to the number of automatic shutdown, automatic shutdown off material.
3. Pneumatic landing plate cylinder, automatic ink mixing after take-off and landing.
4. Reticulate Chuan ink roller, uniform color.
5. Reliable drying system with high-speed operation, automatic shutdown circuit.
6.360 degrees continuously adjustable version installed on the vertical.
7. VVVF, adapt to different printing speeds.
8. Edition of roller seat and close the shelves are loaded somewhat expected move, and stop buttons, easy to manipulate the machines installed version.
9. Release volumes by magnetic powder brake tension control of winding tension control by magnetic powder clutch.

Flexo Printing Machine or Letter Press Benefit:
1. Adopt ceramic anilox cylinder roller to spread ink..
2. The unwinding and rewinding units are designed with magnetic powder brakes and clutch for tension control, and flexography press equipped with Mitsubishi auto tension controller with PLC to control tension stability. 
3. Each flexography press unit adopt 360º for registration. 
4. All printing units are equipped with a group of infrared hot dryer.(UV dryer is for option) 
5.The machine has one die-cutting station, and it can make printing and die cutting finished in one process. 
6. The rubber ink rollers will be automatically separated from the printing roller, and it will keep rotating at a low speed, thus preventing ink from drying.. 
7. The main motor is adopted the import stepless regulation of frequency conversion which guarantees the stable performance of flexography press. 
8. The machine can finish material-feeding, printing, vanishing, IR drying, laminating, die-cutting and rewinding at one stroke that is best option for printing self-adhesiver labels and other commercial label.. 
9.Regular, precise and repeatable results, increased efficiency and also uptime on press, reductions in waste as well as incorrect costs, a lot better communication with whole supply chain, including prepress. 
10.Central impression for better color registration. With the central impression configuration, the printed material is supported by the cylinder, and greatly improving color registration, especially with extensible materials. 
11.Wherever possible, parts are communized for availability and wear-resisting design. Hot wind dryer, automatic temperature controller, and separated heat source. 
12. Hard gear surface, high precision decelerate motor, and encoder buttons are placed on both control chassis and body for operations convenience. 


Flexo Printing Machine or Letter Press Process:
1.Plate making process
The initial technique of plate R&D utilizes light-sensitive polymer. A film negative is positioned over the plate, which is subjected to ultra-violet light. The polymer hardens where light go through the film. The staying polymer has the consistency of chewed gum. It is gotten rid of in a storage tank of either water or synthetic cleaning agent. Brushes scrub the plate to facilitate the "washout" procedure. The procedure could vary depending upon whether strong sheets of photopolymer or fluid photopolymer are made use of, however the concept is still the exact same. The plate to be washed out is fixed in the orbital washout system on a sticky base plate. Home plate is washed out in a mix of water and also 1 % dishwashing soap, at a temperature level of roughly 40 ° C. The unit is equipped with a twin membrane filter. With this the ecological burdening is kept to an absolute minimum. The membrane system separates photopolymer from the washout water. After enhancement of take in gelatine as an example, the photopolymer residue can be dealt with as basic solid waste together with house refuse. The recycled water is re-used without including any kind of cleaning agent. 
2. Mounting process
For every color to be printed, a plate is made and eventually put on a cylinder which is placed in the flexo printing machine. To make a complete picture, regardless of printing on flexible film or corrugated paper, the image transferred from each plate has to register exactly with the images transferred from the other colors. To ensure an accurate picture is made, mounting marks are made on the flexographic plates. These mounting marks can be microdots (down to 0.3 mm) and/or crosses. Special machinery is made for mounting these plates on the printing cylinders to maintain registration.

3. Printing process
A flexographic print is made by developing a positive mirrored master of the required image as a 3D alleviation in a rubber or polymer material. Flexographic plates can be created with analogue and also electronic plate making processes. The picture areas are increased over the non photo areas on the rubber or polymer plate. The ink is moved from the ink roll which is partially immersed in the ink tank. After that it transfers to the anilox or ceramic roll (or meter roll) whose structure holds a certain quantity of ink since it is covered with hundreds of tiny wells or cups that allow it to meter ink to the printing plate in a consistent density equally and also quickly (the variety of cells per linear inch could differ according to the type of print job and also the top quality called for). To avoid getting a final product with a smudgy or bumpy appearance, it has to be made certain that the amount of ink on the printing plate is not too much. This is achieved by utilizing a scrape, called a doctor blade. The doctor blade eliminates excess ink from the anilox roller before inking the printing plate. The substratum is lastly sandwiched in between the plate as well as the perception cyndrical drume to move the photo. The sheet is after that fed via a clothes dryer, which enables the inks to completely dry before the surface area is touched once again. If a UV-curing ink is made use of, the sheet does not have to be dried, but the ink is cured by UV rays instead.
