Abstract
Techniques are described herein for reducing bowing effects on a substrate while the substrate is being transported, for example in an elevator mechanism, from a first travel path to a second travel path, where the first travel path is offset from the second travel path so that the first travel path is not collinear with the second travel path. The substrate can be any substrate that is bowed and for which one wishes to eliminate or reduce the bow. One specific substrate that can benefit from the techniques described herein are personalized documents such as plastic cards including but not limited to financial (e.g. credit and debit) cards, drivers' licenses, national identification cards, gift cards, loyalty cards, employee badges, and other plastic cards which bear personalized data unique to the card holder and/or which bear other card or document information.
