Medium narrow flexographic printing pressure control and adjustment

With the emergence of the packaging market and the emphasis on environmental protection and many other reasons, flexographic printing has increasingly become the focus of printing. When choosing equipment, flexo machine equipment

The operability is also an aspect that should be considered, especially as more and more short-lived versions of the market are now available, saving time for preparations for production to improve production efficiency and output efficiency.

Great effect. The length of job preparation depends on the proficiency of the operator and the structural design of the machine. At the same time, the ease of operation also affects printing.

quality. For example, the way in which printing pressure is controlled, it plays a key role in the control of print quality.

In this design structure, the anilox roller and the embossing roller are fixed in position and cannot be adjusted. The roller can be adjusted up and down and left and right. In the printing process, it is necessary to ensure that the roller

The contact points A, B with the substrate and the anilox roller have a suitable printing pressure. If the pressure is too large, the dots will be deformed and ghosts will appear at the edges of the printing.

Reduced; if the pressure is too small, it will lead to false printing, paste, etc. Therefore, it is necessary to ensure that the plate roller has an accurate positioning in the horizontal direction.

At present, many equipment manufacturers use the positioning pin, or adjust the clearance at the points A and B with a plug to ensure the horizontal position of the roller. This is a certain commitment.

The thickness of the print (usually 0.15mm thickness) was adjusted for orientation. However, when printing thinner substrates, the pressure at point B will decrease when the roll is brought down into contact with the substrate.

Larger, leading to print distortion. When printing a thicker substrate, the platen roller lowers the contacted anilox roller, and the pressure at point A becomes larger and the printing is distorted. To ensure the version of the roller

The pressure in the gap with the substrate will not be too large. Generally, the left roller of the printing plate will be brought into contact with the point A so that the pressure at the point B becomes larger. So if you want to adjust the roller to the best position,

Body operation is more difficult. At the same time, this operation method takes time and the effect is not very good.

Italy Omet flexo printing press has broken through this limitation and adopted a unique design. Taking its Multiflex (420-520-620mm) model as an example, it can be done

The printing pressure and ink supply pressure do not affect each other, and the two are adjusted and set separately. When the operator adjusts the pressure of the platen roller and the substrate, it does not affect the roller between the plate roller and the anilox roller.

The pressure does not affect the pressure of the platen roller and the substrate when adjusting the pressure of the platen roller and the anilox roller. Then, when the thickness of the substrate is changed, especially when the thickness is too thick

When the material is thin, the pressure between the plate roller and the anilox roller can still reach the optimum value. In the specific operation, the operator only needs to press the thickness of the substrate before starting printing.

Adjust the pressure scale value, and then start printing, a very simple operation, you can quickly reach the best position. And the adjustment of the printing roller can be digitally displayed

The operator can remember the position of the digits. It is very easy to restore the adjusted roll position when changing shifts or performing other operations.

This method is simple and quick for the operator, greatly shortens the time for tuning and improves the production efficiency. It also greatly reduces the waste generated by the tuning machine, reducing the

this. From another perspective, it also reduces the printing quality of human factors in the printing process and ensures the consistency of quality. And based on this design, Omet Flexo Press

The printing range has a great deal of flexibility, from 12μ BOPP film up to 0.6mm thick paperboard, including almost all printing materials, can guarantee high printing accuracy

. It is traditionally believed that flexo presses are only suitable for small-format label printing, and today this definition is also undergoing subtle changes. More and more carton packs and various soft

Packaging and printing are all done in a flexo way. In the face of an ever-increasing market for packaging materials, to buy a good flexo press, we must also consider whether the equipment has

Better thickness and material compatibility.

This design is a European patent owned by Omet, Italy. The company has strong R&D strength and can now be said to be in the world in terms of flexo press technology development.

leadership. Omet Flexo Press has unique designs in tension control, drying, automatic overprinting, and web stabilization in high speed printing. Its model set

The use of heavy-duty construction, 3cm thick nickel steel wallboard and 5cm thick die-cut wallboard, to ensure the transmission of the super smooth, is generally limited to the narrow-width flexo presses.
