RISO Technologies’ History of Innovation in Inkjet Head
RISO TECHNOLOGIES CORPORATION acquired the inkjet head businesses of Toshiba Tec Corporation and Tec Precision Co., Ltd. and commenced business operations on July 1, 2024.
We specialize in the development and manufacturing of Piezo On-Demand inkjet heads. Our technology continues to evolve in response to the diverse and demanding requirements of our customers, who deploy our solutions across a wide range of industrial applications.
2002
CB1 Non-Recirculating Inkjet Head
Resolution：150 npi
Drop volume：6-42 pL
Ink：UV、Oil
2003～2006
CA3/4/5 Non-Recirculating Inkjet Head
Resolution：150 npi
Drop volume：6-42 pL
Ink：UV、Oil
2007
CE Series Non-Recirculating Inkjet Head
Resolution：300 npi
Drop volume：6-42 pL
Ink：UV、Oil
Point：By precisely integrating two CA heads, we have developed a head with even higher resolution.
2009
CF1/CF1B Recirculating Inkjet Head
Resolution：300 npi
Drop volume：6-42 pL
Ink：UV、Oil
Point：We developed a channel-recirculation head with a nozzle-level recirculation structure. This enables reduced downtime, enhanced jetting reliability, and minimized ink waste.
2012
CF1BL Recirculating Inkjet Head
Resolution：300 npi
Drop volume：57-80 pL
Ink：UV、Oil
Point：Achieved larger drop volumes by modifying the nozzle size and head structure.
2015
CF1BXL Recirculating Inkjet Head
Resolution：300 npi
Drop volume：36-180 pL
Ink：UV、Oil
Point：With a maximum drop volume of 180 pL, it facilitates solid printing and the jetting of inks with large particle sizes. This model is widely utilized in applications such as ceramic tile printing.
2017
CF3 Recirculating Inkjet Head
Resolution：600 npi
Drop volume：3-20 pL
Ink：UV、Oil
Point：Featuring ink recirculation, this head enables the precise jetting of smaller droplets at higher resolutions. It is increasingly adopted for applications requiring high-definition output, such as small-character printing.
2018
CF3R Recirculating Inkjet Head
Resolution：600 npi
Drop volume：3-20 pL
Ink：UV、Oil
Point：While the CF3 uses air cooling, the CF3R features a water-cooling system. This transition ensures stable operation even under high-load conditions, such as high-temperature environments and high-duty printing.
2024
CF6/CF6R Recirculating Inkjet Head
Resolution：600 npi
Drop volume：6-18 pL
Ink：UV、Oil
Point：By increasing the minimum drop volume compared to the CF3/CF3R, we can now meet the demands of customers who require both high-definition printing and increased production capacity.
2025
CX1 Non-Recirculating Inkjet Head
Resolution：600 npi
Drop volume：6-16 pL
Ink：UV、Oil
Point：The shift to a 1-cycle drive enables an industry-leading frequency of up to 47 kHz. It delivers the ultra-high productivity required for wide-format printing and Sign & Display applications.
