To improve the VLAB100 family, VisionLab has developed the VLAB100CS system, dedicated to 100% quality control of coldseal. Today, verification of the presence of coldseal become important for all printers. For this reason, VisionLab has joined to the traditional 100% print control system, a new coldseal system. Through an in-depth study on the light source, an illuminator was designed to enhance the coldseal on each type of material to perform a dedicated control. VLAB100CS is a very powerful tool that can work independently or correlated to the VLAB100 print inspection system.
