Affect the problem of photo printer printout output image size
Why is there a problem with shortening or lengthening the image size of the print output in the photo machine? How should I solve some problems during the inkjet printing process?
First of all, in the photo machine machine step accuracy problem, if the device can be tuned "stepper", you can set it up, or "compensation settings."
Furthermore, in the photo machine printing paper media factors, because different materials, thickness is different, gram weight is different, the surface roughness of different friction coefficient, so the material forward is different from the size of the resistance, forward fast and slow, but the nozzle ink car running speed is the same; therefore, when production, the need for compensation value correction, That is, according to different materials need to carefully adjust the machine step parameters.
In the photo machine inkjet printing process, about the printing of paper media, is in the place of roll, in advance to constantly relax the material, reduce the resistance of the roll forward. In the production process, there will be shortening and lengthening two phenomena, this phenomenon and material tightness has a great relationship. At first, the material is thicker, the resistance is big, easy to produce the picture shortening phenomenon, and the picture is easy to produce "transverse pattern". Materials more and more books, easy to produce picture elongation phenomenon. Elongation or shortening the problem on the spray drawing image of the quality of the product has a great impact, such as stitching is not on, the length of the frame is different, the length of the screen after the frame is different.
About the photo machine spray painting surface will produce shortening or elongation problem solution:
1, Photo printing image screen in the design and picture output should pay attention to the correctness of the size. When importing pictures using the relevant RIP software, be careful to keep the original size of the image unchanged and avoid changing the actual size of the image due to the reduction of the image size and the operation of the knowledge during the import.
2, for the size of high-demand customers, must open production process meetings to ensure that the production related links are highly valued. Inkjet typesetting files can not be too long, inkjet photo machine step parameters to adjust, requirements to control within three meters of a section.
3, for the need for die-cutting small face advertising inkjet posters, because customers on the size or pattern of the size is extremely sensitive, so we must strictly prevent stretching or shortening, before production to test the correctness of parameters, increase the intensity of sampling.
To do a careful inspection, rigorous operation and inkjet production, as far as possible to reduce the impact of unrelated errors in the photo machine inkjet printout size.
