Quality Scoring Extends Finishing System
Options
Achieving high quality scoring on printing substrates is now said to be achievable with Duplo International (UK)'s new Rotary Score Module for the company's DC-645 production colour finisher.
The modular Rotary Score Module uses a combination of plastic and metal forming wheels to achieve a high quality score, parallel to the paper feed, further extending the number of finishing applications that can be produced on the finishing system, added Duplo Working in the same way as other optional cutting and perforating modules, the Rotary Score Module is provided as a customer replaceable unit that slots in to the existing machine

The Module comprises two tools that can produce up to two continuous scores parallel to the feeding direction.
Each score tool position can be programmed in 0.1mm increments and is positioned automatically, supporting compensation for paper shrinkage and image shift through the integral camera, which reads the true image position on the sheet, said the company.
In a single job the vacuum-fed DC-645 can use the Rotary Score Module, the standard six slitters, cutter and the creaser.

Duplo's Finishing Equipment Transforms Finishing
The School of Oriental and African Studies (SOAS), based in London, which until recently housed an offset printing operation, now finishes 98% of its printed literature in-house digitally.
The vacuum feeder allows for accurate mark-free delivery of a range of stock from 110gsm - 350gsm.
When not required for a job, the score tools will automatically move out of the way of the sheet allowing processing without the need for the modules to be changed over unnecessarily.
That is said to enable an operator flexibility to change from one job to another without the need to reset any hardware.
The DC-645, which was acknowledged as the best finishing solution for digital colour prints at the European Digital Press Association Awards 2007, is Duplo's second generation finishing system for the digital printing sector and combines the functions of slitting, trimming and creasing in one pass.
According to the company, the new Rotary Score Module does not affect the output speed of the DC-645, which can trim to size and crease applications, such as multiple greetings cards printed on SRA3 in one pass at the same speed as other systems perform the creasing.
That saves on time, operator and equipment costs.
A typical application using the Rotary Score Module (such as small greetings cards, or CD size leaflets) can be produced at speeds of up 48 finished items per minute, it is claimed.
If used for scoring alone, the Rotary Score Module can handle up to 40 sheets per minute, said Duplo.
Peter Dyson, product marketing manager for digital finishing solutions at Duplo International, said: "As printers take on more short run digital jobs, we have noticed that growing numbers of them now want to finish layouts by creasing parallel to the paper feed direction.
With the increased number of applications this increases productivity and reduces turn-around times." He continued: "The DC-645 has always been equipped with a matrix creasing bar that can crease perpendicular to the paper feed direction but this is the first time we have been able to produce a score at 90 degrees to this, providing a printer with more options over how to layout the sheet and populate it and with as many items as possible to keep printing time and click charges as low as possible.".
