Overview
The Seiko SPT1020 doubles the nozzle count of the popular SPT510-35PL by combining two 510-nozzle units into one 71.9 mm swathe, raising physical resolution to 360 dpi for high-precision, high-coverage printing. It inherits the SPT510’s proven reliability — steel-plate nozzle protection, internal damper and filter — and adds automatic temperature-compensated voltage control plus the TICKLING function that keeps nozzles from drying out during pauses.

Frequently Asked Questions
Which printers use the Seiko SPT1020 35PL printhead?
Grand-format solvent/UV printers from Infiniti (Challenger FY-3208GS, FY-3266 series), Icontek (M5/M7, TW-3306/TW-3308 series), Phaeton (UD-3266), CrystalJet and SID. Always match the 35PL variant — 25PL and 50PL heads are not interchangeable.
What is the difference between SPT1020 and SPT510?
The SPT1020 is effectively two SPT510-35PL heads in one housing: double the nozzles (1020 vs 510), a wider swath (71.9 vs 71.8 mm with double density) and higher physical resolution (360 dpi vs 180 dpi).
What inks can the SPT1020 jet?
Oil-based, UV-curable and solvent inks. It is widely used for eco-solvent outdoor advertising and UV rigid-media printing.
