Aperture Cards
An aperture card is a punched card with a 2x2 piece of 35mm film set on one side. They are typically used for the storage and retrieval of blueprints or engineering drawings. The microfilm portion may contain one or more A size (8.5x11) through E size (44x34) drawings. Normally the title or other identifying information is keypunched into the aperture card and interpreted across the top. This data is used primarily to programmatically create the index for the job.

The size of the drawing is important because it dramatically affects the price. Should the end user be required to print the document in its original size, it must be scanned as such. If the requirement is only for viewing and it can be printed at a smaller size than the original, a more economical approach can be used. Due to the required processing time, larger size drawings and/or higher DPI affect the price.

Pricing
An aperture card pricing calculator is available for our partners (login required). However for a firm price and production time estimate, send a representative sample of the media to our Florida Headquarters. Please include the required DPI, and a definition of any indexing requirements.
