Converting aperture cards to digital format is a process that can be great benefits for you. Here are some details of a project we just finished.
We recently converted around 100,000 aperture cards to PDF. These were engineering drawings and architecture schematics. We read the hollerith punch code, but some cards did not have the aperture card holes, so we performing a data entry keying from the image.
We sorted the aperture cards by positive vs negative, orientation, and to an extent drawing size, before we started. Preparing an aperture card job is very important, and if you don't have the experience, you could find yourself in a world of trouble once you begin scanning.
A lot of aperture card scanners advertise that everything is automatic, but there is still inventory and prep labor involved in any project. Read more about aperture card scanning here.
