Epson expands printhead range

Epson has announced two new printheads, the I3200(8)-S1HD and S800-S1, which are both variants of existing heads.

These use Epson’s PrecisionCore architecture, which is thin film micropiezo design. The heart of the PrecisionCore technology is a chip, with two rows of nozzles, each having 400 nozzles, so 800 in total, tightly packed together on a 33.8mm line, which gives an effective density of 600 nozzles per inch. The PrecisionCore range have a wide fluid compatibility with these new printheads being suitable for use with UV-cured, oil-based, eco-solvent and solvent inks. 

Paddy O’Hara, Business development manager for Epson Europe, told me: “These heads are suitable for more aggressive solvents. The size and shape of them together with our highly accurate and consistent jetting makes them very interesting for the functional fluid market, but that market uses some challenging chemistry. Therefore with increased solvent resistance it allows us to fulfil more applications in those markets.”

The S800 series use a single PrecisionCore chip and has one channel at 600dpi. This allows for common channel recirculation within the printhead. It measures just 58.1 x 8.3 x 33.8 mm and this small shape makes it ideal for applications where space might be limited, such as direct to shape printers. 

The I3200 printheads use four PrecisionCore chips arranged in a square shape. The existing models can be configured with up to four colour channels but the new I3200(8)-S1HD variant can be set up with up to eight channels. It offers 1200 dpi with two colours, 600 dpi with four colours and 300 dpi with eight colours. However, the multiple channels precludes any recirculation within the head. Nonetheless, it’s a very flexible printhead and should be suitable for a variety of applications from single pass through to scanning printers.

O’Hara adds: “The eight separate channels allows applications where multiple functional fluids are needed in a compact space.”

Both of these printheads should be available from April. You can find further details from epson.com
