The printhead is one of the core components of UV printers, which largely affects the productivity, accuracy and even price of UV printers. There are many types of UV printer printheads, and there are different types of industrial printheads under different brands.
Which UV printer printhead is better? How to choose a UV printer with printhead? Hope the following article can help you.
1.RICOH head
Ricoh nozzles have been widely used in UV printers since 2013, and are currently the most popular industrial nozzles in the industrial UV printer market.
| MH5420/GEN5 | MH5320/GEN6 | |
| printing width | 54.1mm | 54.1mm |
| drop quantity | 1280 | 1280 |
| DPI | 600dpi | 600dpi |
| jet frequency | 30kHz | 50kHz |
| variable | ±15% | ±5% |
| jet straightness | ≤1.0deg | ≤0.29 deg |
| veracity | ±8μ | ±5μ |
| drop size | 7/14/21pl | 5/10/15pl |
Regardless of the effect, speed and life, it has a very high cost performance.
2.Konica head
Konica nozzles entered the marketing earlier, and they are a very mature product on the market.
| KM1024a | KM1024i-SHE | 6988H | |
| ignition ferquency | 40kHz | 60kHz | 38.5kHz |
| drop size | 6-20pl | 6pl | 13pl |
Konica nozzles are double-row ink inlet tubes with uniform flow and pressure. Konica nozzle models mostly used on UV printers are 1024i and 512. Among them, 512 is a fully enclosed nozzle, which has advantages in waterproof and anti-aging. With the high requirements of the market for printing effects, Konica launched 1024a, which is mainly for high-speed industrial printing, including UV printing, textile printing, and ceramic inkjet printing.
3.Kyocera head
Kyocera printhead are the nobility of printheads. The advantages of the Kyocera nozzle are reflected in the number of drop: 2656, the maximum ignition frequency: 30KHz, and the effective printing width: 112.35mm, so the Kyocera nozzle has a great advantage in production capacity.
4.Seiko head
Seiko nozzles entered the market in 2009. They belong to a relatively early industrial nozzle with aluminum alloy shell and a service life of 2-3 years. Using one nozzle to produce one color, the inkjet speed is relatively fast.
5.Toshiba head
Toshiba is mainly a gray-scale printhead. High precision, with special nozzle protection device.In the field of UV printers, the Toshiba CE4M nozzle is currently used more.

| type | drop quantity | width (mm) | resolution | ignition frequrncy | drop size | head width(mm) | highest temperature used | ink type |
| Gen5 | 1280 | 54.1 | 600dpi | 20-30kHz | 7-21pl | 89*24.51*69 | 60℃ | uv/eco /waterbased |
| Gen6 | 1280 | 54.1 | 600dpi | 40-50kHz | 5-15pl | 89*24.51*66.3 | 60℃ | uv/eco /water-based |
| 6988H | 1024 | 72 | 360dpi | 27.5-38.5kHz | 13pl | 131*18*94 | 55℃ | uv/eco |
| 1024a | 1024 | 72 | 360dpi | 40kHz | 6-20pl | 131*18*98 | 55℃ | uv/eco |
1024i SHE | 1024 | 72 | 360dpi | 50-60kHz | 6pl | 131*18*94 | 55℃ | uv/eco |
| kyocera | 2656 | 112.35 | 300dpi | 30kHz | 3.5pl | 200*36*68.5 | 55℃ | uv /waterbased |
| Seiko | 1024 | 73.17 | 360dpi | 30kHz | 7pl | 60℃ | uv/eco /water-based | |
| Toshiba | 636 | 53.7 | 300dpi | 28kHz | 5pl | 85*75*34 | 50℃ | uv/eco |
Buying Guide
Most of the industrial-grade printhead that are widely used in the market are produced in Japan. When you plan to purchase, you can consider the following four points:
Firstly, the service life of the nozzle
Industrial printers use industrial print heads, which generally have a long life.
Secondly, the printing speed of the nozzle
The easiest way is to look at the number of drop. If the number of drop is large, the speed will not be slow.
Thirdly, the printing effect of the nozzle
Look at the drop size, the smaller the value, the higher the resolution.
Fourthly, the stability of the nozzle itself
Good or bad, the easiest and most direct way to look at the manufacturer and market share!
The above are the types of printheads shared by the editor for you. If you want to know more about the infomation, please continue to pay attention to our website or contact us.
