SPGPrints’ new RSI III – the third generation of
its rotary screen printing integration module for label and packaging presses –
features time, safety and ergonomic innovations for increased production
efficiency. Operator safety has been augmented with the introduction of guards
to prevent contact with the rotating screen, squeegee pipe and gear wheels,
significantly reducing the risk of injury.
A new web-cleaning scraper, positioned on a guiding
roller immediately after the nip between the screen and substrate,
automatically removes undesired ink splashes on the web that may have spilled
from the screen during stoppages or slow-rotation mode. Operated only for the
first one-and-a-half screen rotations at the start of the production run, the
scraper ensures thorough drying of the substrate at all times. This minimises
the risk of ink contaminating the rollers, thereby reducing the cleaning
requirement. Its long-life plastic
blade collects the UV-curable ink in a pan attached to the scraper, which is
easily removed for fast cleaning.
A new colour interface display offers enhanced
visibility with a wider angle of observation. This means that operators can
comfortably monitor and control the unit without needing to view the screen at
eye level, minimising risk of strain injury. Among other benefits, this
facilitates easier monitoring of controls and ink levels.
The RSI III unit is fully compliant with the latest
version of European Union RoHS (Restrictions of Hazardous Substances)
regulations which stipulate that all electronic machine components and
manufacturing processes must be free of materials hazardous to health and the
environment.
Introduced in 1994, and with over 1000
installations worldwide, SPGPrints’ RSI module has enabled the seamless
integration of rotary screen printing into single-pass label converting lines.
The process is vital for creating a host of value-adding sensual and functional
features that enhance brand presentation or product identification. The RSI
module, along with with SPGPrints’ pure nickel re-imageable RotaMesh® and
reusable RotaPlate® rotary screens, are often used for creating tactile
varnishes, metallic and glitter inks, opaque inks, braille dots and optically
variable inks for security applications. They offer easy robustness, print
stability and easy handling, for laying down thick ink and varnish layers of
max. 250µm thickness at web speeds of up to 150m/min (490fpm).
