The new Seiko RC1536 L high-discharge printhead has proved a winning solution for Equipe Ceramicas, which has adopted it to apply the special gloss finish on its wide range of small-size decorative ceramic floor and wall tiles, produced in square, rectangular, triangular and hexagonal sizes, including 3D effects.
According to the Spanish company, the biggest improvements concern product quality and creativity. “Seiko printheads have helped to stabilise the production rate while maintaining quality, something that we did not get with other previous printheads. At the same time, the discharge quantity and drop volume can be varied over a wide range covering all our needs, from subtle shades through to the most intense colour tones,” says Raúl Torres, Design Manager at Equipe Ceramicas.
The RC1536-L ink circulation printhead is the latest addition to SII Printek's industrial inkjet printhead product range. It provides 70 g/m² discharge at a speed of 25 m/min (or 35 g/m² at 50 m/min), with a drop volume from 13 to 150 pl or from 25 to 225 pl. The high quantity of ink deposition intensifies the glossy effect and improves surface flatness; while constant ink circulation allows for the removal of bubbles and impurities, ensuring a longer nozzle lifetime and significantly reducing ink consumption.
Other features include high productivity and cost efficiency. Featuring an extra wide print-width (108,3mm) enables print-bars to be configured with a small number of printheads.
Isolated channel technology allows the printhead to operate at high frequency (up to 37kHz) and achieve eight levels of greyscale with a drop range size between 25pl to 225pl. The printhead can also accept a wide range of viscosities compared to conventional printheads. SII Printek is part of Seiko Holding Group.
