Why are some high-speed bottle tumbler printers coarse and blurry with the same head and hardware configuration while others are excellent?

Mainly affected by several aspects

1. Waveform

There is a fixed waveform inside each head chip. The waveform directly affects the ink output intensity, ignition frequency, inkjet point, etc. of the head. It is equivalent to the basic origin. If the head waveform is not adjusted according to the corresponding software waveform, interruptions will occur. Problems such as ink, roughness, oblique spraying, etc., and before the waveform is adjusted, it cannot be repaired no matter how hard it is repaired. In the most serious case, it will affect the entire head channel and prevent ink from being discharged. Waveforms are also divided into large points, midpoints, small points, single points, variable points, etc. Different inkjet requirements correspond to different points, and different inkjet points also have special waveforms, so if the above problems occur, the first thing is The waveform is not adjusted properly or the waveform does not match the software and ink.

2. Curve

The curve is the most important part of color software, which plays a role in the transition, compensation, accurate point-to-point injection, color calibration, ink volume, etc. This is why the printing effects produced by two machines from the same manufacturer, the same machine, and the same type of head are different in color, which requires curve adjustment. Especially the gray level, it is almost impossible to print a standard gray without the adjustment of the curve.

3. Ink

Different ink manufacturers have different ink formulas. Some ink manufacturers are lighter, some are thicker, some are cyan, some are reddish, some have more solvents, some have strong adhesion, etc. The waveforms and curves corresponding to different inks are different. It needs to be adjusted, so it is not recommended to frequently change ink from different brands, because manufacturers usually repeatedly test the matching of the ink with their own machines. The price of the ink is not simply the first factor. The smoothness and adhesion of the ink need to be taken into consideration. The taste, the shades of color. These require constant adjustment and testing to match your own machine. The most direct cause of changing the ink rashly is to block the head. In fact, it does not really block the head, because the replaced ink does not match the waveform curve of the machine you are currently using.

4. Machine installation

It is mainly the assembly personnel’s debugging and material matching, including the straight-line level of the beam, the flatness, and the straight-line level of the overall horizontal levelness, material selection and matching are also very important. These will affect the printing effect and accuracy. The finer the pattern, the higher the machine assembly requirements and the overall deviation cannot exceed 0.03 mm.
