Introduction :

A flexographic (flexo) printing machine is a type of printing press of HAVESINO MACHINERY that uses flexible rubber or polymer printing plates to transfer ink onto a substrate. It is commonly used for printing on various materials, including packaging materials like labels,cardboard, plastic, flexible film, towel, tissue paper and more.

Application

The stack flexographic printing machine is a multi-functional printing equipment suitable for printing various types of materials. Here are some examples of materials that stacked flexo printers are typically capable of printing: Paper: including various glossy papers, offset papers, coated papers, thermal paper etc. Film: Plastic film, such as polyethylene (PE), polypropylene (PP), polyester (PET), etc. Composite: A composite film or paper composed of different materials, such as aluminum foil. Textiles: Some laminated flexographic printing machines can be used to print textiles, such as cloth or nonwovens. Metallic materials: Some printers may be able to print on metal sheets, such as aluminum foil. Label materials: Suitable for label printing, including various label papers and films. Packaging materials: Used for printing various packaging materials, such as cartons, paper bags, etc.

A flexographic (flexo) printing machine is a type of printing press that uses flexible rubber or polymer printing plates to transfer ink onto a substrate. Here's a brief introduction to key aspects of a flexo printing machine:

Plate Material:

* Flexo printing equipment uses flexible printing plates made of rubber or photopolymer. These plates are mounted on cylinders to transfer ink to the substrate. Flexo printing is popular for various applications, including flexible packaging, labels, newspapers etc.

Ink Application:

* The engraved cells on the anilox roller control the amount of ink applied to the plates.

The ceramic anilox roller is a vital part of flexographic printing machines, ensuring precise ink transfer for consistent and high-quality prints. Known for durability and wear resistance, it's ideal for industries like labels and packaging.

Drying:

*Depending on the ink used, a drying or curing process is employed in the 1-8 colors flexo printing machine.

Flexo printer's hot air drying:

Rapidly dries ink for efficient and high-speed printing.

UV curing and solvent evaporation are common methods to ensure the ink sets properly on the substrate.

Differences between stack-type flexo and regular flexo printing machines:

The main differences between stack-type flexo printing machines and regular flexo printing machines lie in their printing methods and structural designs. Here are some key distinctions:

Printing Method:

Regular Flexo Printing Machine: Adopts direct printing, with minimal interaction between color channels.

Stack-type Flexo Printing Machine: Utilizes stack printing, allowing the overlay of multiple color channels in the same position. This method enhances color richness and accuracy.

Number of Color Layers:

Normal Flexo Printing Machinery: Typically suitable for printing tasks with a small number of colors.

Stack-type Flexo Printer Machine: Permits overlaying multiple colors in the same position, handling a greater number of color layers. Printing

Precision and Color Depth:

Regular Flexographic Printing Machine: May have limitations when dealing with complex patterns and requiring higher color depth.

Stack-type Flexo Printing Press Machine: More advantageous in handling complex patterns and achieving higher color depth due to the ability to overlay multiple colors.

Production Efficiency:

Regular Flexo Printing Press: Suitable for simple printing tasks, offering potentially high production efficiency.

Stack-type Flexo Printer:

More efficient when handling high-end printing tasks that require multiple colors and layers.

In summary, stack flexo printing machines demonstrate a clear advantage in dealing with complex printing tasks requiring more colors and higher printing precision. The choice between these types of flexo printing machines typically depends on the requirements of the printing task and the production environment.
