The Chromira is a digital LED photographic printer which sharpens each pixel and then prints them at a higher resolution. This generates 425 Pixels per Inch printed on the page with the corresponding image quality. Images printed on Chromira are far superior in image quality to images from an ink jet printer. The resolution of Chromira is specified in continuous tone Pixels Per Inch. Inkjet printers specify resolution in Dots (of ink) Per Inch. It is generally considered that it takes 5-6 times the resolution in dots per inch to match continuous tone resolution. Thus it would take an ink jet printer of at least 1500 Dots per Inch of resolution to equal the quality of Chromira's prints at 300 Pixels per Inch.
