Product Description
This Vest Bag Flexo Printing Machine adopting photosensitive resin as printing plate, is commonly known as the flexographic printing machine. It is suitable for printing packing materials such as polyethylene, polypropylene plastic bag and roll paper, etc. It is a kind of ideal printing equipment for producing paper packing bag for food, supermarket handbag, vest bag and clothes bag, etc.

Performance and characteristics:
1. Easy operation, flexible starting, accurate color register.
2. The meter counter can set printing quantity according to the requirements. Stop the machine automatically at the quantity or when the material is cut off.
3. Lift and lower printing plate cylinder manually, it will stir the printing ink automatically after lifting.
4. The printing ink is spread by the anilox cylinder with even ink color.
5. Reliable drying system coordinated with high-speed rotation, it will automatically break circuit when the machine stops.

Vest Bag Flexo Printing Machine has a benefit over lithography in that it could utilize a larger array of inks, water based rather than oil based inks. It is basically a modern-day version of letterpress which can be made use of for printing on almost any kind of kind of substrate, including plastic, metal film, cellophane, paper, foil, acetate film, and also other materials and laminating material made use of in packaging. Normal products printed using flexography include brown corrugated boxes, flexible packaging consisting of retail and purchasing bags, food and health bags and sacks, milk as well as drink cartons, flexible plastics, self-adhesive labels, disposable cups as well as containers, envelopes as well as wallpaper. Recently there has actually also been an action towards laminates, where two or even more materials are adhered together to produce new product with different commercial properties compared to either of the originals. Flexography printing is extensively utilized in the transforming market for publishing plastic materials for packaging and also other end uses. For optimal performance, the flexography presses generate big rolls of product that are then slit to their finished dimension on slitter.

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 printing press. 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. 

Flexography printing machine, commonly abbreviated to flexo press is a kind of printing process which utilizes a flexible relief plate. It is basically a modern-day version of letterpress which can be made use of for printing on almost any kind of kind of substrate, including plastic, metal film, foil,cellophane, paper, and laminating material. 
The 2nd technique made use of a computer-guided laser to etch the photo onto the printing plate. Such a direct laser etching procedure is called digital plate making. 
The 3rd approach is to go through a molding procedure. The primary step is to create a metal plate from the negative of our preliminary image via a presentation procedure followed by an acid bath. In the early days the metal used was zinc, resulting in the name zincos. Later magnesium was made use of. This steel plate in relief is then utilized in the second action to produce the mold and mildew that could possibly be in bakelite board or maybe glass or plastic, with a first molding procedure. When cooled, this master mold will press the rubber or plastic substance (under both regulated temperature as well as stress) through a 2nd molding procedure to produce the printing plate. Flexography printing machine is a new flexo press that has actually been made to please the short run printing needs of the flexible packaging industry as well as the top-notch printing demands of the plastic, paper and self-adhesive label market. It consists of advanced digital systems to accomplish the most effective hard copy high qualities and it can be applied to different substrates, i.e., plastic film, paper as well as laminates. 
The perfect option that can be adjusted to publish with traditional solvent based ink systems, with water based inks and UV inks for the label market and with the ingenious technology for flexography printing. 
This expert flexo printing press operator excels in the areas of color administration, procedure control, troubleshooting and implementing corrective activity procedures to bring systems right into control for repeatable, foreseeable results.
