Factors affecting the accuracy of the dtf printer nozzle
Many printing factories have at least one white ink heat press machine, which is usually used to make small orders or make patterns. However, the requirements for pattern making on the nozzles of white ink heat press machines are very high. After all, only high-precision nozzles can print finer heat transfer products. So what factors can directly affect the accuracy of the nozzle of the white ink heat press machine? TEXTEK will discuss with you.
1. The smallest ink drop of the nozzle
Generally speaking, the smaller the ink drop, the higher the printing accuracy, but sometimes it is necessary to choose the most suitable combination according to the requirements of ink volume and gray scale.
2. Number of nozzles
The number of nozzles has a great influence on the printing accuracy, and the splicing of nozzles with four-color/eight-color ink output is more demanding.
3. The number of passes printed
For the same color input, the smaller the number of passes, the higher the accuracy. This is one of the reasons why the staggered arrangement is not as accurate as the side-by-side.
4. Matching of ink and nozzle
Whether the ink can contact the medium with round ink droplets will affect the effect, so the ink should be highly matched with the nozzle.
5. Arrangement of nozzles
Under the same conditions, using staggered will increase the width of the print, but will sacrifice accuracy.
6. Transmission accuracy of printing equipment and flatness of platform
The transmission accuracy and flatness of the platform will affect the placement of ink dots and affect the printing accuracy.
7. Waveform collocation of board and nozzle
The stability of the chip signal output and the printing requirements of the waveform will affect the printing accuracy.
