Aperture Card Scanning
Aperture cards are a type of card used to archive engineering drawings. Mounted on the card is a small piece of 35mm mircofilm that contains an image of one or more drawings. Often times the aperture card contains a human readable drawing number on top and punched holes readable by specialized equipment. The punched holes may relate to the drawing number and revision number or other index information.
How do you scan an aperture card?
Our service of scanning or converting aperture cards to digital provides many user benefits including digital storage and ease of viewing, printing or moving the drawing from one location or another. Scanning an aperture card is similar to scanning microfiche. The card is installed in a microfiche scanner and the operator will scan 1 card at a time adjusting the resolution, contrast and other scanner variables to achieve the best possible image. Black and white and grayscale are most common settings. Grayscale settings will often produce a sharper image however the file size may be 10X > the black and white settings.
