For the first time, Tichawa Vision is going to exhibit at drupa. Specialized in the field of high-precision CIS Contact Image Sensors for industrial product control, Tichawa Vision is going to present its new VARICIS designed for demanding inspection tasks in the fields of digital, inkjet and security printing booth (F30, hall 3). The multicolour industrial scanner is the first CIS offering adaptable resolution. What makes VARICIS a unique camera system for quality control is its compactness and scanning speed.
VARICIS sensor has been specially designed for the requirements of the printing industry. It is the first CIS with adaptable resolution (1200, 600 and 300 dpi). Due to its slim design and very compact construction, it is possible to integrate the VARICIS sensor into printing machines without installation effort. Another advantage of the VARICIS is the constant view during the entire scanning width via its 1:1 optic. Due to its small distance of approximately 10 mm to the printing object in inspection, the VARICIS sensor generates a distortion-free and significantly sharper picture in comparison with conventional line scan cameras.
Prior to each printing job the CIS system checks if the nozzles are in the right position and if they are operative using a calibration process. If nozzles are missing or adjusted incorrectly, the user will be informed immediately and will be able to correct the mistake. The multicolour VARICIS guarantees for colour stability throughout the whole printing process via its integrated liquid cooling, thereby eliminating colour deviation.
Due to the extraordinary line rate of up to 250 kHz and a scanning speed of up to 20 m/s the VARICIS is optimally suited for very fast running printing processes. The sensor is available for scanning widths from 260 to 2080 millimeters.
“At the drupa we’ll meet decision makers from all over the world who are focussed on automated systems for quality control in printing processes“, explains Dr. Nikolaus Tichawa, managing director of Tichawa Vision. “We hope for a successful premiere on the drupa, including various talks and discussions which will give an important impulse to our work.”
Tichawa Vision develops and manufactures Contact Image Sensors (CIS) for inspection of flat materials as an alternative to conventional line cameras. The CIS includes in one housing a reading guide line, an optical system, and a light source for high-precision applications, e.g. the printing business. Tichawa has developed a wide range of cameras that offer high reliability in design as concerns power consumption, functionality and size.
