Color inkjet printers are boasting overwhelming popularity due to their low costs, high speed and high quality print. A high quality imaging technology has been developed for color inkjet printers using a piezoelectric print head. We have worked toward inkjet printers that use pigment ink with light-resistance and water-resistance because requirements for fast color have recently risen. That is a new MACH (Multi Layer Actuator Head) which is most important to produce those characteristics.I'd like to introduce you to the MACH technology for pigment ink.1. The structure of MACH2. The technology to achieve high speed color print and high quality print by MACH• The increased number of nozzles• The meniscus control• The prevention of clogging by quivering meniscus
