The HP Designjet 4500 Scanner can scan large-format color and black-and-white drawings up to 42 inches wide for easy printing, copying and saving. With a resolution of 508 dpi optical and 2400 ppi enhanced from three cameras and a 0.1 percent line accuracy, scanned files are indistinguishable from new output, and reproduce the original documents precisely. The monochrome Dual 2D-Adaptive enhancement technology produces clean and crisp scans even from poor-quality originals.
Many students use the scanner to convert pen-and-ink drawings into digital images to include in their portfolios. The scanner accepts non-abrasive paper, vellum, Mylar, sepia, blueprints, plastic, film, plastic laminate, foam board, cardboard (no plywood, stone plates, metal plates or abrasive, dirty, rough, sharp-edged, metal-clamped or burned surfaces). The most common problem we have encountered with drawings is that there can not be any white-out correction fluid on them because it causes smudges. |
