Product Description
Seiko 508GS Printhead – Product Information
The Seiko 508GS Printhead is a reliable industrial inkjet printhead designed for consistent performance and long service life. Manufactured by Seiko Instruments in Japan, it delivers accurate ink droplet control for high and stable print quality. This SPT-1020/12pl printhead is a grayscale design with a built-in damper assembly and nozzle guard, available as the original Seiko part number IRH2533 (and the earlier IRH2513 generation).
Compatible with solvent, UV, and water-based inks, the 508GS printhead is built for continuous use and is widely used in commercial and industrial inkjet printhead systems. The IRH2533U printhead is the replacement for IRH2513 printheads using UV and solvent inks, while the water-based variant is the replacement for IRH2513 printheads running aqueous fluids. It suits a wide range of large-format printers including Infiniti Challenger, CrystalJet 6000 Series, Icontek, and Kerajet K700 platforms.
