Colortrac has a center floater roller that allows you to scan fragile documents. It will scan pattern paper.
Both are CCD Scanners. Colortrac has an extra camera to give better focus.
Contex still uses fluorescent bulbs (replacement is up to $900-, because you can’t just replace the bulb, you have to replace the sleeve). When the bulb dims, as fluorescent bulbs do, more calibration is required, and a warm up period is required before you can use the scanner. Colortrac uses LED’s. They last forever (almost), they are instant on and they provide a constant bright white light. There is no degradation from end to end because of weak spots on the bulb.
Colortrac optional SmartWorks Pro Scan provides a scan-once Software, so you can make all the adjustments after the scan.
