How to ask questions about the UV printer heads like an old hand and get more real data? After all, the printhead is the core of the equipment. Printing speed, accuracy, stability, service life, maintenance, etc. are closely related to the printhead. Let’s first understand the meaning of the 10 technical parameters of the UV printer heads.
1. Printhead series model
It refers to the model of the series of the printhead. You should know that dozens of different models are under each series of printheads. These models have low-end, mid-end, high-end, and top-level levels, and the price is several times or even dozens of times different.
2. Number of nozzles
This refers to the number of nozzles on a single printhead. The more nozzles there are, the more ink is produced, and the printing speed will increase accordingly.
3. Printhead width
It refers to the physical length and width of the head. The longer the width, the larger the area of the print scan pattern, and the faster the printing speed. Just like a mop, the wider the head, the larger the area of the mop.
4. Number of color inks
Some printheads have one color, some have two colors, some have four colors, some have eight colors, and some support mixed colors. This can help users meet the color needs of printed products with fewer printheads.
5. Printhead price
Generally refers to the terminal price. There are two points to note. Try to choose mainstream printheads so that the price will not change much and there will be no shortage of supply; secondly, try to buy from the original equipment manufacturer or printer parts supplier. After all, the warranty installation and debugging are included. In addition, most users cannot distinguish the authenticity of the printhead, encryption or not, etc.
6. Ink drop size
Generally expressed in PL. The smaller the value, the higher the corresponding printing accuracy. It should be noted that PL is a unit of volume, and many industry practitioners will also make mistakes in this detail.
7. Printhead grayscale
The grayscale levels of the printhead are generally 0, 4, 8, 12, etc. The larger the value, the better the performance of the printhead. The ink droplet size can be automatically adjusted according to the requirements of the printing mode and printing effect.
8. Printhead life
It refers to the service life of the printhead, which is generally measured in years and months and rarely in hours. Moreover, the difference between theory and practice is very large, and many factors affect its life, such as UV ink quality, personal operation, daily maintenance, etc. The longer the actual service life of the printhead, the more expensive the relative price.
9. Applicable ink
It refers to what type of consumables the printer should use. Even if the printheads of the same series and the same model are suitable for UV inks, some are suitable for solvent inks, and some are suitable for water-based inks. This difference is very large, and they cannot be mixed.
10. Printhead warranty
At present, among the UV printer manufacturers, some have a two-year or three-year warranty for the equipment printheads they provide, and some do not have a warranty. In the process of understanding, ask about this clearly, and at the same time, the details and requirements of the quality assurance must also be made clear.
Of course, in addition to the above indicators of the printhead, there are also ignition frequency, physical accuracy, connecting wires, internal structure, materials, etc., which are too technical and rarely mentioned in actual inquiries.
If you ask about the UV printer heads like an old hand, you can interpret questions based on the above 10 technical indicators. On the one hand, this can show that you are very professional and avoid being fooled by some salesmen. On the other hand, you can judge the performance of the printhead according to these indicators.
