The Seiko 1024GS HG-S 7PL Printhead (IEA1024N07-2F01) is a genuine original Seiko Instruments high-grade small-drop grayscale piezoelectric printhead for solvent and UV ink wide-format printing. With 1,024 active nozzles across a 72mm print width at 360 dpi native resolution, a firing frequency of 30 kHz and multiples, and multi-drop grayscale capability delivering up to 5 drops per nozzle firing — enabling effective drop volumes up to 35 pl from a 7 pl base — it delivers fine-detail, smooth-gradation output for high-quality graphics and signage production. Built-in damper assembly ensures consistent ink flow; integrated non-wetting nozzle plate and nozzle guard protect against contamination and physical damage. Compatible with Infiniti, Munda, and Ntek wide-format printers using solvent and UV inks. Every IEA1024N07-2F01 we sell at Digiprint USA is 100% genuine original Seiko Instruments.
Solvent/UV only — NOT compatible with aqueous water-based inks. The Seiko 1024GS HG-S (IEA1024N07-2F01) is configured for solvent and UV inks. It is not interchangeable with the Seiko 508GS 12PL water printhead (IRH2533U-1420). Always confirm your printer's ink type before ordering. Installing a solvent/UV head in an aqueous system, or vice versa, will result in ink seal damage and permanent head failure.

Frequently Asked Questions
What does HG-S mean — and how is it different from HG-L?
HG stands for High Grade — Seiko's premium 1024-nozzle printhead tier. The S and L suffixes refer to drop size: HG-S is the Small Drop variant (7 pl base, up to 35 pl in 5-drop grayscale), optimised for fine-detail, high-resolution output where smooth gradations and precise dot placement are the priority. HG-L is the Large Drop variant (28 pl base), designed for higher ink coverage and throughput applications where maximum drop volume matters more than minimum drop size. Both use the same 1024-nozzle, 72mm, 360 dpi platform. Your printer's OEM specification determines which is required — they are not interchangeable.
What does "up to 5 drops" grayscale mean for the 1024GS HG-S?
The Seiko 1024GS uses multi-drop grayscale: each nozzle can fire between 1 and 5 drops in rapid succession per pixel position. At 1 drop, the effective drop is 7 pl (finest detail, highlights). At 5 drops, the effective drop reaches 35 pl (maximum coverage, deep shadows). This gives the head a continuous tonal range within a single pass — smooth gradations without extra passes or complex dithering. Combined with the 30 kHz frequency, this enables high-quality wide-format graphics at production speeds.
Is the 1024GS HG-S compatible with eco-solvent inks?
Yes — the IEA1024N07-2F01 is compatible with solvent inks, which includes both hard solvent and eco-solvent formulations, as well as UV-curable inks. It is not compatible with aqueous (water-based) inks. If your printer uses water-based inks, you need the Seiko 508GS 12PL Water Printhead (IRH2533U-1420) instead. Confirm your ink type with our team before ordering.
Do you ship the Seiko 1024GS HG-S 7PL to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse before 2PM EST. Our Miami location is ideal for Latin American Infiniti, Munda, and Ntek solvent/UV production shops using freight forwarders in the Doral area.
