Digital printing Riso's HC5000 sets benchmarks in semi-professional color printing According to a survey recently presented by IT expert Robert Weiss of Robert Weiss Consulting at a press conference organized by Fritz Schumacher AG (Schumacher), sales of color page printers are developing significantly better than those of mono and black-and-white page printers. Specifically, sales of color printers in Switzerland have increased by 87 percent from 23,000 to 43,000, while sales of mono printers have fallen by over 20 percent from 168,000 to 132,000 units. In other words, documents are becoming more colorful. However, this trend is probably not only due to the fact that color is simply cool and in demand, but is certainly also related to the significant price changes. While mono page printers have had to cope with a shift (= reduction) in average prices of just over 13 percent, color page printers have become almost half as cheap, so it's no wonder that Schumacher also wants to take a slice of the color printer pie in the future. To this end, the company has added a new color page printer from RISO Kagaku (Riso) to its product portfolio.
Now also available in Switzerland
Schumacher wants to score points in Switzerland with the Riso HC5000 color printer. The printer, which caused a sensation among experts at the drupa trade fair in May 2004, is now available and is being launched on the Swiss market by the Zurich-based company. The fast high-speed full-color printing is possible thanks to a joint development by Olympus and Riso - based on a new inkjet technology related to the piezo inkjet process, which Riso calls Forcejet.
105 pages/minute - color
The Riso HC5000 processes paper from DIN A6 format to DIN A3 oversize format (340 x 550 mm) - and at an exhilarating speed. In this way, the color printer advances into areas that were just the benchmark for black and white printers: With its print speed of 105 pages per minute, the HC5000 is the fastest full-color printer in the world in the business segment. The printer achieves this record thanks to its line inkjet head system, which uses print head lines instead of a print head (which usually has to move back and forth). Although this technology is not entirely new, the HC5000 is at least the first high-speed full-color printing system to use this technology for double-sided printing. The speed here is therefore an impressive 74 pages per minute. The figures refer to the standard resolution of 600 dpi; with the finer, maximum resolution of 900 dpi, the print performance is reduced accordingly.
With costs of just 6.25 centimes per page, the operating costs of the HC5000 are between a third and a tenth of the comparable costs of standard color printers, according to Werner Studer, Sales Manager at Schumacher. The ComColor controller, which was also developed by Riso and is based on PostScript 3, is also responsible for the low printing costs and high throughput. This rip allows the printing of changing data sets and enables users to print their documents automatically sorted as required. This saves manual sorting - and ultimately time.
With the optional multifunction finisher, printed documents can be stapled, hole-punched or folded into dossiers, brochures etc. in the future. However, the finisher, which also enables the offset output of documents, is not yet available. Werner Studer expects it to be available this summer.
Copy at high speed
The HC5000 can also be upgraded to a high-performance copier. For this purpose, a high-performance scanner (Epson GT 1500) is connected, which captures the documents to be copied. Scanners, cables etc. are available directly from Schumacher.
All in all, Riso has developed a high-performance workhorse for printing color documents. This is also confirmed by the information on the service life (6 million prints) and the monthly print volume (20000 to 250000 pages). Overall, they lead to very good operating costs (TCO). Schumacher AG has already been able to convince a cantonal authority and two print shops of this and of the Riso HC5000 printing system.
