Blueprint Scanners

Advantages

• High resolution
• Best possible image

Disadvantages

• High cost
• Can’t do real world images (like a camera)
• You have to take blueprints apart.

Blueprint scanners produce the best possible output of a blueprint.

Because CAD ESTIMATOR is capable of using really large image without any performance penalty, you’ll be able to work at very high resolution.

There is not much point in scanning higher than 400 dpi in black & white. You can read everything at that resolution. 

Cad Estimator reads all the standard files produced by a blueprint scanner. Including LZW compression in tiff files.
