Cabeça de impressão Seiko RCE2560 is an industrial-grade piezoelectric inkjet developed by the printhead division of Seiko Instruments (SII). It made its first appearance at drupa 2024, positioned as a 600dpi high-resolution head aimed primarily at textile printing and corrugated cardboard packaging, while also being suitable for a range of substrates including glass, metal, and ceramics.

Cabeça de impressão Structurally, the uses four staggered rows of nozzles for a total of 2560 nozzles, with an effective print width of 108.3mm, achieving high output density within a compact footprint. The jetting frequency reaches up to 40kHz, and combined with the 600dpi resolution, single-pass print speeds can reach approximately 100 meters per minute. At a throw distance of 3mm, the jetting velocity is around 7 meters per second. Drop volume supports multi-level greyscale, with a standard range of 9 to 20 picolitres, extendable to around 30 picolitres in certain configurations.

Do lado técnico, o recurso de destaque do RCE2560 é a integração de recirculação verdadeira, tecnologia de canal isolado e um controlador de forma de onda integrado de última geração. A tinta circula continuamente em alta velocidade diretamente atrás dos injetores, o que reduz o entupimento dos injetores e as bolhas de ar, ao mesmo tempo que garante uma ejeção de tinta estável e uma qualidade de impressão consistente durante execuções de produção longas e contínuas.

Cabeça de impressão In terms of ink compatibility, it is an upgrade from the previous-generation RC1536 (360dpi). The core piezoelectric elements and electrode process are carried over, but speed has been significantly improved for water-based inks, opening the door to new applications such as packaging and textiles. Beyond water-based inks, it can also jet UV-curable, oil-based, and solvent-based inks, with a compatible viscosity range of roughly 5 to 20cP. It should be noted that the itself does not include heating or temperature-control modules; temperature management is recommended to be handled by the machine’s ink supply system.
