ProFire Excel Laser Imaging
The Presstek 52DI incorporates 10 multi-beam laser diodes on each of its ProFire Excel Imaging modules.
The Presstek 34DI incorporates 6 multi-beam laser diodes on each of
its ProFire Excel Imaging modules.
ProFire Excel, Presstek’s latest generation laser imaging technology, delivers exceptional image quality while dramatically reducing the possibility of moiré patterns in standard screen rulings. Fine details, color fidelity, minimum screen values, and large solids are produced with results that meet the most demanding offset printing needs.
ProFire Excel easily supports screen rulings up to 300 lpi and FM (stochastic) screening.
ProFire Excel combines all of the imaging components—infrared laser diodes, laser drivers, data electronics, and motion control— into one compact system. The foundation of ProFire Excel is a single image data board that controls the laser diodes. Each diode contains four uniquely addressable, 16-micron beams for high reliability, unmatched accuracy, and high-resolution imaging.
