Heidelberg's New Workflows and RIP
Heidelberg will be supplying customers with the latest release of its automated prepress workflow, Prinect Printready System 1.2, with immediate effect.
Kohlschein manager and head of marketing, Oliver Hiflich, summarised his impressions of the machine: "The display production process is much more effective with the Varimatrix 105 CS because staff no longer have to strip manually and are able to concentrate on more skilled work.
The automated production process also eliminates manual sources of error." Prague print shop K P R, where the Czech Republic's first Varimatrix 105 CS has been running since last summer, also swears by the die-cutter, added Heidelberg.
Commercial printing used to be dependent on external suppliers but the Varimatrix has now made it possible to generate much greater added value in-house.
Ji Tomek, print shop director at K P R, said: "Because the wide variety of jobs we undertake necessitates relatively frequent die-cutting, we have also invested in post-press.
In addition to the greater flexibility of the Varimatrix 105, we particularly appreciate its high productivity and shorter make-ready times.
Thanks to the die-cutter, K P R achieves production speeds of 6,000 to 7,000 sheets per hour, depending on the complexity of the job.
At the same time, thanks to the large sheet format of 75cm x 105cm (29.5" x 41.3") that can be processed - more blanks per sheet can be printed and die-cut on the Varimatrix." He continued: "The main factor in achieving significantly shorter make-ready times than with the old die-cutters was the fact that the Varimatrix offers a whole host of automation and control elements that provide information relating to the individual machine component settings.
We are now also able to archive tools - once they have been set up - with the help of thin, exchangeable plates.
This significantly reduces the preparation time for repeat jobs." Heidelberg added that the Prague print shop currently uses the Varimatrix 105 CS for runs of approximately 100 sheets and above, but the die-cutter can also be used for jobs running to over 300,000 sheets.
The GP-Tryk print shop has been operating Denmark's first Varimatrix CS 105 for over a year, longer than any other company.
It was brought in to replace a Heidelberg cylinder press.
Jan Sortkjir, co-owner of GP-Tryk, said: "With the Varimatrix, we can handle all kinds of jobs - whatever the format.
Our productivity has increased by several hundred per cent and our quality is also much better.
The capacity is unbelievable.
It has made us very competitive, in particular for print runs exceeding 4,000 copies.
Most other companies have difficulty keeping up with us." Henrik Kruse, co-owner and head of sales at GP-Tryk, added: "The die-cutter has won us many new customer and new orders." Heidelberg claimed that the Varimatrix 105 CS cuts and embosses paper of 80gsm and above, card or solid board up to 1,400gsm, as well as corrugated board up to a thickness of 4mm (0.16") at a maximum processing speed of 7,500 sheets per hour and a maximum cutting force of 300 tons.
The sheet formats that can be processed range from a minimum of 370mm x 400mm (14.6" x 15.7") to a maximum of 750mm x 1,050mm (29.5" x 41.3")." The Varimatrix 105 CS is said to score well thanks to its flexibility and short make-ready times.
User guidance via a touch screen display ensures easy handling and small jobs can be processed productively.
The company added that The Varimatrix already incorporates gripper margin removal as standard.
The die-cutter works according to the principle of a mobile lower plate, ensuring high-quality die-cutting.
The variable lock-up frame can be used for various die-cutting dimensions, which means that existing die-cutting tools can still be used.
In the feeder itself, a double sheet detector ensures that sheets are fed in to the system reliably and precisely.
To enable the print sheets to be processed accurately, the standard lays on both sides of the machine can be switched directly from pull to push mode.
In the cutting station, stripping is performed with complete tools or using upper and lower pins.
In addition to the Varimatrix 105 CS, for packaging applications Heidelberg said it offers the Dymatrix 106 CSB (B stands for blanking) die-cutter, which has been available since Drupa 2004.
The Dymatrix is intended for complex applications with a claimed maximum speed of 9,000 sheets per hour.
A further option is the Dymatrix 142 CSB, a die-cutter for 100cm x 140cm (39.4" x 55.1") formats.
The range also includes ECO and Diana folder gluers, which fold and glue packaging made from cardboard and corrugated board.
