Gandinnovations recently introduced improved printheads to its Jeti line of inkjet printers. Jeti printers use 80-picoliter Spectra heads to support 300-dpi resolution, but new 50- and 30-picoliter printheads will enable users to produce graphics at resolutions up to 400 and 600 dpi, respectively. Gandinnovations will offer these printhead upgrades as an option on any new Jeti printer at no additional cost to the customer.
