Rapida Optima QK 1765 is formulated for high-speed presses where fast job turn-around is critical. It uses specially developed HiT varnish components, enabling the inks to set rapidly to a hard, scuff- and mark-resistant film surface, making it possible to back up press runs within five minutes. The new inks also lower the amount of spray powders required while significantly reducing blocking and offsetting to a minimum, allowing printers to pile printed sheets higher. The inks are wax-free and are UV coatable and may be laminated.
In addition to their fast-setting properties on a wide variety of substrates, Rapida Optima QK 1765 inks are compounded to stay open on a press for extended periods of time and open in the can for periods of up to three days.
“The Rapida Optima QK 1765 series is the fastest ink we have ever developed, and yet it still performs well on press,” said David Daffern, technical director.
