Most of the flatbed printers on the market today are designed with multiple printing modes for customers to choose from, which can cope with various printing situations. But there may be a print effect that is not ideal, the color does not have a sense of hierarchy, no brightness, which is why? Flatbed printer printing operations should pay attention to what to avoid such situations?
What is the principle of color change?
First of all, we need to know why flatbed printers can choose a variety of printing modes, and a one-time print multi-color, rather than traditional printing in the need to set the color it? That is because the current market UV flatbed printer uses multiple color control technology, so most of the realization can control 8 colors, a wide range of color areas. Multiple color control technology through the control of the ink droplet concentration can be each color according to the shades of 1 to 9 color changes, so you can fully cope with a variety of color printing, and can play white and varnish printing, making the color brighter degree to a higher level, and expressive and layered.
The strict control of the ink selected by the uv printer.
According to the above-mentioned principle of color change, want to achieve good printing results, it is necessary to strictly control the ink selected by the uv printer, if the ink is not up to standard, the water content is too high, the ink is easy to spread, the ink droplets are difficult to control, it is not possible to correctly control the color shades so that the color shades mixed, the printing effect will not have a sense of hierarchy, color glossy is not enough.
Air humidity should be kept moderate.
In addition, the air humidity in the working environment to maintain a moderate, because the flatbed printer in the work either before printing or after printing is very taboo water. If the air humidity is too wet, it will make the printing material moisture, resulting in unsatisfactory printing results. So to keep the air humidity moderate, that is, to compensate for the loss of moisture in the ink due to heat, but also to ensure that the printing material is not damp, printing work smoothly.
