Riso RZ1090U One-Color Digital Duplicator – 031924000433A

S/N: 78720025

The RZ1090 imaging technology is based on proven offset printing processes using liquid ink and digitally imaged master plates to produce runs up to 4,000 prints. The simple “green-button” operation is as familiar as using a common copier; simply press one button to create, load, and unload natural fiber master plates and automatically begin printing. Automated production processes streamline workflow, maximizing machine availability to produce more jobs faster than ever before. Commercial printers, quick printers, copy shops, corporate in-plants, school districts, university print shops, large churches, and more will all benefit from the expanded capabilities of the RZ1090.
