Imprint Digital has revamped the finishing department at its plant near Exeter, installing two three-knife trimmers from Horizon and replacing a BQ470 four-clamp binder with a new version.
“It will run with EVA glue for the most part, though will also do PUR,” says production director Adam Roppert. The company produces books for its owner publisher Imprint Academic and also for third-party publishers and thanks to a web to print service, will print and finish jobs for non traditional publishers.
It has moved up from a Horizon HT80 to the more powerful HT1000V which is connected inline to the BQ470. All were supplied by IFS in Hemel Hempstead. “The HT80 was fine, but it was a traditional three-knife trimmer which took time to prepare and to maintain,” says Roppert. “The HT1000 gives us three-knife trimming of any book and any size and takes 30 seconds to set up.”
This is needed as run lengths continue to edge downwards. An average of 250 copies is flattered by the occasional run of 2,000 or so. The majority of runs fall around 100 to 200 copies. Size as well as thickness is changing frequently. “The things we get that people claim is A5 is ridiculous,” he says. "But the HT1000V can cope with anything and any format we throw at it."
The company is also running an HT30 trimmer to finish the even shorter run proof or sample copies bound on a BQ270 single-clamp binder. If these short runs increase into book of one production, the fast set up on the HT1000V will be invaluable.
Imprint Digital runs Konica Minolta C1100, C1070 and C6000 for colour and has two cut sheet Canon presses, a C6250VP and C6160VP, for the text sections. While suited to short runs, Imprint Digital is handling longer runs on these, when they ought to be litho jobs, because, Roppert says, the publishers and designers are scattering colour pages throughout the book rather than concentrating the illustrations into separate sections.
The company is also handling an increasing volume of case bound work and has bought a dedicated end papering machine to alleviate the problems of producing suitable book blocks on the existing binders where the spine is milled to accept the glue for perfect binding.
“It should solve the production speed issues and enable us to produce high quality hard back books as well as quality paperbacks,” Roppert says.
