We at Qualitas have been hard at work trying to develop solutions for high speed printing. Traditional Area Scan cameras don’t typically work for continuous scanning in a web. The challenges are limited frame rates which don’t match up to the web speeds. This becomes even more challenging as the required resolutions are higher – which would then require area scan system with both high frame rates as well as large resolutions. Another challenge is the synchronization of frame triggers with Area Scan cameras – makes for challenging electronics!
Line scan applications overcome these limitations with the use of single line scanning with high scan rates (typically 8, 16, 36 Khz). Take a look at a setup that we have used for hologram Inspections below:
