The DBM-500 combines a sheetfeeder with a collating unit. It is designed for firms that need to finish a mix of digitally printed electronically collated work with conventionally produced offset.

"It's a major departure for us, and as far as I know is unique," said Duplo vice president of global marketing Dominic Quenell. "Printers kept asking whether to get a sheetfeeder or a collator when they needed a machine that did both."

Duplo has coined the term "dual line" to describe the machine's ability to work near-line with digital output and offline for conventional work.

Other advances include a 25% speed increase over the DBM-400 to 5,000 booklets an hour and dynamic fold roller spacing. This is claimed to produce flatter booklets. It automatically adjusts the distance between the fold rollers based on the number of sheets fed from the collating tower.

At Igas the firm also launched an improved version of the DC 545 slitter, cutter, creaser. The new version can handle heavier stocks and has improved cutting accuracy. This feature was particularly requested for finishing business cards according to Quennell.
