Presstek's newly developed ProFire® Excel Imaging System is equipped with two imaging heads with built-in lasers. The two imaging heads can simultaneously form an image onto the plates for four colors with precise registration on each plate cylinder. The laser spot size^* of 16μm provides a resolution of 2,540 dpi, ensuring high-precision printing reproducibility. This imaging system can handle AM screening up to 300 lines per inch (120 l/cm) and FM (stochastic) screening (option), providing the flexibility to meet the growing demand for a diverse range of short-run color printing.

With the simple click of a button, new printing plates are positioned automatically and the used plates are wound onto take-up spools. An optional plate saver kit advances each plate the minimum distance necessary for each color according to image size.

The 3404X-DI and 3404E-DI use a satellite V-shaped 5-cylinder system consisting of two sets of double-diameter blanket cylinders and plate cylinders, which rotate around a triplediameter impression cylinder. Paper is tightly held by the impression cylinder grippers and rotated twice without a gripper change for precise 4-color printing. The large diameter of the impression cylinder reduces paper curling as well as damage to the printed material.
Thanks to this cylinder arrangement, the RYOBI 3404X-DI and 3404E-DI achieve a remarkably compact design that is about the same size as a conventional 2-color press.

Roller temperature is maintained at the optimum level by circulating temperature-controlled water (warm water and cold water) inside the oscillating rollers and fountain rollers. By minimizing fluctuations in ink roller temperature, consistent printing quality is maintained, even during long print runs.

The UV curing unit quickly dries surfaces printed with an exclusive waterless UV curing ink, eliminating the time normally spent waiting for the ink to dry, so work can move immediately to subsequent processes such as back side printing, sheet cutting and bookbinding. Job turnaround time is dramatically reduced and there is no need for extra drying space. Combining UV printing with the high print quality of offset printing greatly enhances versatility.
