One of the commonly used printing machines, Stormjet piezoelectric printer, has higher printing accuracy and better color reproduction effect, so how can the piezoelectric printer's drawing effect be improved? Let's take a look together below.

1. Image resolution requirements:
Pictures usually require 72DPI/inch. If the image is too large (such as the file size exceeds 400M when the new image is displayed in PHOTOSHOP), the resolution can be appropriately reduced and controlled within 400M.

2. Image mode requirements
The printing picture uses the CMKY mode uniformly, and the RGB mode is prohibited. Stormjet piezoelectric printer are printed in dual four-color, and their colors are completely different from the printing colors. Of course, when drawing, they follow the printing standards.

3. Requirements for the black part of the image:
It is strictly forbidden to have a single black value in the photo image. It must be filled with C, M, and Y colors to form a mixed black. If it is big black, it can be made as follows: C=50 M=50 Y=50 K=100. Especially when using the effects brought by PHOTOSHOP, pay attention to changing the black part to four-color black, otherwise there will be horizontal lines on the black part of the screen, affecting the overall effect.

4. Size:
The size of the printing image is the same as the actual required screen size, it is different from the printing. In inkjet photo companies generally have blank borders after outputting pictures. You can discuss with the advertising company, how many white borders are left for buttonholes. The price is calculated per square meter, so the screen size is in centimeters.
