Fujifilm Dimatix, which specializes in drop-on-demand inkjet print heads, has expanded its existing Samba family, with the introduction of the Samba GMA line of products. The GMA products will be based on Si-MEMS technology along with the Samba G3L (single-pass focus).
The Samba GMA is described by the company as a compact, low voltage, full silicon MEMs print head designed for scanning applications such as textile, indoor signage, soft (dye sub) signage and high quality UV printing. Samba GMA print heads are based on silicon micro-electro-mechanical systems manufacturing (Si-MEMS).
With 384 individually addressable nozzles, the Samba GMA 33 print head has a native 300-dpi resolution and a native ink drop size of five picoliters (pl) that can jet a range of fluids like UV curable, solvent, and aqueous inks.
Fujifilm explains through continuous ink recirculation directly behind the nozzle and several innovations including nozzle plate design, specialized nozzle plate geometry, and waveforms tailored to specific fluids, known as RediJet, this process provides a range of potential of the Samba GMA print head. RediJet allows the print heads to be quickly and easily primed, explains the company, resulting in faster time to print, minimal ink waste and greater reliability.
Fujifilm’s VersaDrop jetting technology used by the new print heads allows multiple fixed drop sizes in binary mode and grayscale capability from one print head, with no loss to productivity. In binary operating mode, the Samba GMA print head is designed to eject adjustable drop sizes from five to 18 picoliters, and can support grayscale levels as defined by the users control electronics.
