Logical relationship of printing accuracy of digital printing machine

Digital t-shirt printing machines serve different types of textile digital printing enterprises, and their requirements for printing accuracy are also different. We are also determined to provide more stable and more efficient digital printing and printing equipment, where printing accuracy is also an important production requirement. What are the indicators and printing accuracy related to? Let's sort out our ideas;

1. The smallest droplet of the print head

The smallest ink droplet of conventional nozzles on the market generally ranges from a few picoliter to tens of picoliter. Generally speaking, the smaller the smallest ink droplet, the higher the printing accuracy. Sometimes, you need to choose a few levels of gray based on the ink volume and grayscale requirements. Printing, printing with a combination of large, medium and small ink drops.

Second, the number of nozzles

Under the same conditions, the increase in the number of print heads of the clothing digital printing machine will affect the printing accuracy. The processing accuracy of the industrial head trolley bottom plate is high, and the single/two-color ink is discharged. The linear combination has little effect on the printing accuracy. The four-color/eight-color ink nozzle Combined splicing has higher requirements for positioning, and generally has a slightly greater impact on printing accuracy.

Third, the arrangement of nozzles

Under the same conditions, the staggered arrangement will increase the printing width, and the number of printing passes needs to be increased, which will sacrifice the printing accuracy.

Fourth, the matching degree of ink and nozzle

Whether the ink can contact the medium in a round ink droplet will affect the effect, so the ink should be highly matched with the nozzle.

5. Waveform compatibility of board and print head

This is relatively common. Different T-shirt personalized custom printing manufacturers have slightly different board control algorithms. The stability of chip signal output and the requirements of the waveform for printing will affect the printing accuracy.

Sixth, printing equipment transmission accuracy and platform flatness

The transmission accuracy and the flatness of the platform will affect the ink drop position and affect the printing accuracy.

Seven, 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 does not have high accuracy.

Eight, the type of medium

The coating certificate of the piece printing machine media has good ink absorption performance, and the ink does not bloom or spread, and the corresponding printing accuracy will be improved.
