Russian print shop installs Rainbow device

A print shop in Russia is has installed a Rainbow device on its Heidelberg Speedmaster SM 102 six-colour UV press, enabling simultaneous processing of different inks in a single ink fountain.

The Rainbow device features a knife-type ink fountain, individually adjustable ink distribution and ink separation in the ink fountain.

The different inks combine in a single ink fountain to produce controlled fine lines on the sheet.

The resultant vignette within the print motif is key to security printing, according to the company.

A customer in the Netherlands has started using the first Speedmaster XL 105 equipped with a Rainbow printing device.

Rainbow printing is already available on the Speedmaster SM 52, SM 74, XL 75 and CD/SM 102 series.

The presses are mainly used for the print of banknotes, security papers, cheque cards, drivers' licences, identity papers, postage stamps and tax stamps.
