How does the UV printer print picture lengthen or shorten

04/01 2022

In the process of using UV printer, there are very strict requirements for the size accuracy of UV printer image, so what’s the matter with the lengthening or shortening of UV printer print image? Next, let’s explain it in detail.

The UV printer picture will be shortened or elongated

First of all, with regard to the stepping accuracy of UV printer machine, if the equipment can adjust the “stepping”, it can be set or “compensation setting”.

Furthermore, in the factors of UV printer printing paper medium, because of different materials, different thickness, different gram weight, different surface roughness and different friction coefficient, the resistance of materials moving forward is different, fast and slow, but the running speed of nozzle inkcart is the same; Therefore, during production, the compensation value needs to be corrected, that is, the stepping parameters of the machine need to be carefully adjusted according to different materials.

In the printing process of UV printer, the problem of retracting and releasing the printing paper medium is to relax the material in advance at the place of unwinding, so as to reduce the resistance of coil material. In the production process, there will be two phenomena: shortening and stretching, which is closely related to the tightness of materials. At the beginning, the material is relatively thick and the resistance is large. It is easy to shorten the picture, and the picture is easy to produce “horizontal lines”. The materials are getting thinner and thinner, which is easy to produce the phenomenon of picture stretching. The problem of lengthening or shortening has a great impact on the quality of image products, such as mismatched splicing, different lengths of mounted pictures, different lengths of pictures after mounting plates, etc.

Solution to the problem of shortening or lengthening the picture of UV printer:

1. Pay attention to the correctness of size when designing and outputting realistic images. When importing pictures with relevant RIP software, pay attention to keep the original size of the image unchanged, so as to avoid the actual size of the image being changed due to the reduction of the image size during import and recognition operation.

2. For customers with high dimensional requirements, a production process meeting must be held to ensure that relevant links of production attach great importance to it. Typesetting documents cannot be arranged too long. The stepping parameters of UV printer should be adjusted well, which is required to be controlled within three meters.

3. For small format advertising posters that need die cutting, because customers are extremely sensitive to size or pattern, they must strictly prevent stretching or shortening. Before production, test the correctness of parameters and increase sampling inspection.
Do careful inspection, rigorous operation and production, and minimize irrelevant errors affecting the print output size of UV printer.
