Seiko 508GS Printhead | SPT-1020/12pl Print Head for Industrial Inkjet Printers

Product Description

Genuine Seiko 508GS Printhead (IRH2533) — 508 nozzles, 72mm print width, 12pl grayscale drop volume & 18kHz firing frequency. Solvent, UV & water-based variants for Infiniti, CrystalJet, Icontek, Kerajet & other large format inkjet printers.

Seiko 508GS Printhead (IRH2533) | 72mm Industrial Inkjet Printhead

The Seiko 508GS Printhead is a highly reliable industrial inkjet printhead designed for consistent performance and an extended service life. Manufactured by Seiko Instruments in Japan, it delivers highly accurate ink droplet control for superior print quality. While a compact i3200 epson is typically used for light-duty DTF or eco-solvent applications, the Seiko 508GS is built to withstand the harsh chemical compositions of aggressive solvent and UV inks that would quickly degrade a standard epson print head or hp printer head.

This SPT-1020/12pl printhead features a grayscale design with a built-in damper assembly and nozzle guard. Available as the original Seiko part number IRH2533 (the direct replacement for the older IRH2513 generation), this printer printhead is compatible with solvent, UV, and water-based inks. It is the trusted workhorse for continuous-use commercial and industrial inkjet printhead systems, seamlessly fitting into wide-format platforms like the Infiniti Challenger, CrystalJet 6000 Series, Icontek, and Kerajet K700.

Key Advantages of the Seiko 508GS Printhead

✔ Industrial-Grade Reliability & Longevity

Engineered for high-volume production environments. Unlike a disposable hp printer head, the 508GS is designed for maximum operational uptime and low maintenance requirements over a long service life.

✔ Excellent Print Coverage (72mm Width)

Features 508 nozzles across a wide 72mm active print width. It jets drop volumes up to 7 x 12pl, providing flexible print quality and heavier ink laydown than standard small-format inkjet printhead models.

✔ Aggressive Ink Compatibility

Available in dedicated solvent/UV (Green Label) and water-based (Blue Label) variants. This allows the printer printhead to integrate seamlessly into systems running harsh chemical fluids.

✔ High Firing Frequency (18 kHz)

Operates at up to 18 kHz (and multiples), enabling fast, smooth, and consistent printing at high carriage speeds without sacrificing image quality.

✔ Stable Grayscale Resolution

Native resolution of 180 dpi with effective multi-pass performance up to 720 dpi. The 12pl grayscale capability delivers sharper text and smoother gradients than binary-only industrial heads.

✔ Non-Wetting Plate & Built-In Damper

Comes equipped with an integrated damper assembly and a protective nozzle guard. The non-wetting nozzle plate prevents ink buildup and protects the inkjet printhead from accidental scratches during maintenance.

Seiko 508GS Printhead FAQ

The Seiko 508GS industrial inkjet printhead is used in commercial large-format printers for high-volume signage, banners, vehicle graphics, and industrial packaging. It is specifically designed to jet aggressive solvent and UV inks at high speeds.

The i3200 epson and standard hp printer head are designed for light-duty, low-viscosity inks and have a relatively short lifespan under heavy stress. The Seiko 508GS is a ruggedized printer printhead with a built-in damper and non-wetting nozzle plate. It handles highly viscous, aggressive solvents that would destroy a standard epson print head, making it a true industrial workhorse.

The physical dimensions and jetting performance (508 nozzles, 72mm width, 12pl drops) are identical. The difference lies in the internal fluidics and seals. The Green Label variant is chemically resistant for solvent and UV inks, while the Blue Label variant is optimized for aqueous, water-based inks. You must choose the correct variant for your inkjet printhead system.

The IRH2533 is the current, modern replacement generation for the discontinued IRH2513 printhead. It offers the same drop volume and footprint but features updated internal piezo technology for better reliability and consistency. The IRH2533U drops directly into printers originally designed for the IRH2513.

This printer printhead is widely used in the Infiniti Challenger series (FY-3208GS, FY-3208T, etc.), CrystalJet 6000 Series, Icontek wide-format printers, Kerajet K700 ceramic printers, Leyenda, Nuocai, OraJet, and Dupont ICHINOSE Artistri 3320 machines.
