Underpinning the Perfection 4490 Photo's high level of performance is its 4800dpi Matrix CCD (Charge Coupled Device) and Micro Lens technology combination. Adding even greater scanning resolution power is the scanner's ability to move the optical carriage at 9600dpi with Micro Step Drive - a feature that has consistently provided Epson Perfection scanner users with brilliantly clear images exhibiting high colour consistency.
Featuring also an optical density of 3.4 Dmax, the Perfection 4490 Photo affords significant improvements over earlier models in capturing details in both highlight and shadow. The results are highly detailed scans which, when printed on an Epson Stylus Photo printer, deliver outstanding photographic prints.
