blue-fina Laser Engine
A 405 nm laser diode, fibre dot-matrix, automatic focusing, light-power balancing and constant temperature control, integrated into one unit. It is what gives the machine the power to engrave a fine screen.

Blue Rotary UV Laser Engraving Machine
Rotary screens imaged directly by laser, in two breadths: 2200 mm and 3500 mm. Repeat is 640 mm as standard with 820, 914 and 1018 mm available, so it covers the repeats a rotary printing line actually runs. Engraving takes six to eight minutes a metre at the standard repeat.

What we do around it
We specify the machine from the screens your printing line runs — breadth, repeat and the detail your designs need — clear it through Egyptian customs ourselves, and install and commission it on your floor. Our technicians are on call afterwards, and we hold the fast-moving parts in Cairo.
