Industrial inkjet print head specialist Xaar has added two new greyscale print heads to its wide-swathe Proton inkjet family, both delivering 15 picolitre drops at high speed.
Mark Alexander, director of marketing at Xaar, says, “Our aim is to give printer manufacturers and their customers a wide choice of sophisticated, but cost-effective, print heads so they can select the very best technology for their specific applications.”
The new Xaar Proton 15 uses Xaar’s drop optimisation technology to print in binary or greyscale modes. In greyscale mode, 15, 30 and 45 picolitre drops can be used simultaneously to print a single image. Xaar says this allows fine detail to be combined with smooth tones. Alternatively, in binary mode, an image can be printed using a single drop size selected from this range.
The company says its other new print head, the Xaar Proton 15+ adds internal ink temperature control to enable the print head to work with a variety of ink types and viscosities, adding that precise temperature control is important for maintaining high quality printing in environments where ambient temperatures may fluctuate during the day, or from season to season.
It also says the robust design of the Xaar Proton 15, with lockable ink and electrical connections, ensures easy and secure installation. The integration of intelligent on-board electronics reduces development costs and time-to-market for printer developers, according to Xaar.
