The visual effects of UV printing have three-dimensional effects, such as flat plain color printing, 3d, 4d and 5d. Among them, ordinary color printing is also divided into two-color, four-color, six-color, eight-color, eleven-color and so on. The more spot color UV inks used, the finer the pattern display.
1. The physical accuracy of the print head
Refers to the number of ink droplets in the nozzle. The smaller the value, the higher the accuracy and the finer the printing lines. For long-distance outdoor viewing, large-hole sprinklers are more suitable; for indoor close-ups, small-hole sprinklers are better.
2. Physical accuracy of UV flatbed printer
It refers to the physical error between the core components such as the screw rod, the trolley, the motor, and the platform. The smaller the value, the better the printing accuracy of the pattern can be guaranteed. When selecting equipment, users should check the brands of parts and understand their process and performance indicators.
3. Pattern pixels
The picture format printed by UV flatbed printers usually uses vector graphics. psd, tiff, ai, etc. are very common. The pixel size must be greater than 300dpi. The higher the value, the better the effect.
4. Adjust the color curve
The color curves used in different application scenarios are different, especially in the advertising industry, where the influence of color difference is relatively large. This depends on the curve used by the UV flatbed printer and the adjustment of the technician;
5. Printing software settings
For example, how many passes are selected for printing, the larger the value, the better the effect. Feather opening value, white ink printing ink volume, embossing parameter settings, etc.
6. The characteristics of the material itself
Some of the 5d and 6d effects on the market require the material itself to be multi-faceted, so that it looks like a 3d effect from multiple angles.
7. Color matching
Under normal circumstances, the standard configuration of UV flatbed printers is 4 colors + 1 white, which can meet 90% of the demand. However, some export or high-end needs can only be realized by using six, eight, or even eleven colors. The more colors are used, the richer the layering and delicacy of the pattern.
