HP has used Print 17 to unveil the Indigo 12000 HD B2 digital press and launch its Indigo 50000 to the global market. An upgrade on its existing Indigo 12000 B2 press, the new 12000 HD digital press, which is not yet commercially available, uses new high-definition writing heads to double image resolution to 1,625dpi, surpassing offset printing, according to the manufacturer. The new high definition imaging system, which incorporates new software and writing heads, will also be available for retrofitting onto most HP Indigo 10000 and 12000 presses. The four-colour Indigo 12000 was launched at Drupa 2016 and can print at speeds of up to 4,600sph on sheets up to 750x530mm. Pricing and commercial launch date for the new Indigo 12000 HD press and retrofit option are currently not available, but a late 2017 or early 2018 date is expected.
