How to address light and dark stripes in plotter prints?

In the field of digital printing, plotters are important output devices and are widely used in advertising, decoration, photography and other industries. However, during use, light and dark stripes often appear when the plotter is printing, which not only affects the quality of the printed product, but also may have a negative impact on customer satisfaction. So, when the plotter prints unevenly, we should first eliminate the following possible faults and come up with corresponding solutions.

1. The nozzle is blocked or reaches the end of its life

It is necessary to print a cleaning test strip. If the nozzle shows a black block, it means that the nozzle is damaged; if there is a break in the middle of the nozzle, it means that it is blocked and can be used again by cleaning.

2. The pressure of the paper pressing wheel is too high

The medium is deformed by the paper pressing wheel and cannot be restored in a short time, resulting in the nozzle inkjet height being different during printing, and it is easy to have marks and produce light and dark stripes. The pressure of the paper pressing wheel needs to be adjusted.

3. Poor ink absorption of the medium

Try to use some standard media with good ink absorption. When printing, you can observe whether there are cracks and no ink absorption in the darker part, as well as slow drying. If there is such a phenomenon, it means that a standard medium needs to be replaced.

4. Ink quality problem

Poor-quality ink can cause the nozzle to be blocked, resulting in stripes when printing. Therefore, it is best to use ink produced by ink manufacturers with a certain scale and technical strength. It is cost-effective and has corresponding quality assurance. For example, the ink produced by AoBoZi plotter is strictly tested before leaving the factory. The ink is fine and guaranteed not to clog the nozzle.

1.Fine ink quality: produced in a dust-free workshop, after a three-level filtration system, the ink is free of impurities, fine and smooth, ensuring that the machine is in the best working condition.

2.Strong compatibility: suitable for a variety of printing media, fast drying speed, suitable for rapid mass production of enterprises.

3.Wide color gamut: using high-quality imported special dyes, color saturation, good reproduction, can more delicate and realistic reproduction of the real picture.

4.Strong weather resistance: not easy to fade.
