The Durst Lambda is a continuous roll-to-roll single beam, 3-laser (RGB) exposure system giving total size flexibility and achieves an image quality which is superior to all large format printers – photographic, inkjet and electrostatic). The Durst Lambda exposes digital information (raster pixel) directly to conventional photographic media at full continuous tone with a linear writing speed of up to 65 cm (26 in.) per minute with the choice of two resolutions of 200 and 400 ppi (equal to an apparent resolution of 4000 dpi). The Lambda produces images with the highest possible resolution (68 billion colours) and with a radiometric repeatability of 0.025 D per colour. Prints can be produced to an infinite length and when the 50 inch paper width is exceeded, images are automatically divided-up and exposed in strips.
