One of the most popular and widely used printing methods is flexographic printing, which is widely used in the label printing industry; But what is flexo printing and how does it work? This article introduces this type of printing and examines its features. To find the answer to the question of what flexo printing is, stay with us. First of all, it is better to know what flexography is? Flexographic printing is actually a type of technique that uses a flexible printing plate to perform the printing process. Flexo printing has flexible photopolymer printing plates and these plates are wrapped around cylinders and on a press. Ink plates contain a raised image and rotate at high speed, thereby transferring inks through small holes from the anilox roll to the substrate. Through flexo printing, you can print an instant business card in the desired shape and design.
Flexo Printing Process
The flexo printing method is carried out during the following steps:
First, the substrate roll is opened and the sheet passes through a series of printing stations.
An anilox roller (made (made of steel or aluminum) with an engraved surface and shallow indentations sinks into the ink.
The anilox roller is then wiped with a blade to leave an even and uniform layer of ink.
The ink is applied to the plated images. .
The substrate is then pressed onto the screen, this is crimped by a molding cylinder that applies the proper pressure and transfers the image onto the surface.
A UV lamp or IR dryer dries the ink before the next process. they dry Bazar print collection provides the possibility of printing in various ways, including flexo printing, and can provide customers with all kinds of prints in the highest quality.
The Importance of Flexo Printing
Metal printing, which is considered one of the most important printing methods today, and its technologies are improving day by day. This type of printing is done from gelatin plates or photopolymer and dilute ink that has a high drying process or water-based ink and by the metal printing machines discovered, they all have a roll printing method. Through this type of press, you can easily do all kinds of required printing, such as label printing.
The Benefits of Flexography Printing
Its execution speed is very high and it can be used for long prints.
They can be printed on different types of materials under the layer.
It is installed in the shortest time and leaves little waste.< br> The quality of the final output is guaranteed.
There is no need to do additional work and the cost of electricity, such as printing, varnishing, laminating and cutting the mold, and it is all done in one process. did.
Composite Transfer in Flexo Printing
The process of transferring the compound from the raised form to the substrate in metal platform printing depends on various conditions and factors:
The thickness of the compound on the desired form
When the form is in contact with the printed surface.
The pressure value of the form is in contact with the printed surface.
Types of Flexo Print Plates
one-layer plate
in a single-layer plate, a bottom layer is placed in order to stabilize the plate, and exposure is done from the back side until it hardens, after that the protective layer is removed and the plate They let light in and then wash.
Multilayer plate
This plate can be used to achieve high quality halftone printing. The presence of the base layer can prevent the deformation of the embossed layers, which are very thin and malleable. It absorbs the laser and is cut by it. In general, this layer is responsible for the negative map of the film and can stabilize the plate.
Types of Flexo Printing Machine
✅Cylinder Central Impression Flexo
✅Stack Flexo Flexo
✅Linear Flexo InLine
Flexo printing machines are classified into three main types: stack machine: this machine is It is a type in which printed towers are placed one after the other or upside down. Common Impression Presses: Unlike stock machines, this type of machine does not have pressure in each cylinder unit and instead uses one large cylinder for all colors.
In-Line Machines:
The printing towers in this machine are arranged horizontally and one after the other. One of the features of the machine is the possibility of printing in two types of roll and sheet materials.
