BST International highlights Nyquist digital strobe for print inspection

BST International and Nyquist system together exhibited TubeScan, the world's first digital stroboscope for the label control, at Labelexpo Europe. TubeScan uses a modular PC system and a high quality digital image recording unit. Thus, the system allows for convenient coarse monitoring, that reliably detects defects such as labels, grid residues and missing ink even with reflective and metallized surfaces.

Additionally, on LabelExpo a new upgradable software module is introduced, which checks print and color with high accuracy. TubeScan covers working width of 330mm, 450mm, 650mm and 850mm and is available in three versions— TubeScan, TubeScan+ and TubeScan++.

Tapan Patel, managing director and co-promoter, said, “Conventional methods such as counting of repeats, detection of missing labels with photoelectric sensors or the visualisation of moving webs with strobe lights often reach limitations and are complicated to use. On the other hand, automatic print inspection systems based on line scan cameras might be oversized and too expensive for many applications. Hence, the concept of TubeScan sets a new standard with the smart combination of imaging technology and the stroboscopic principle. TubeScan provides considerably higher process reliability with the base function digital strobe because it always delivers a steady image and true colour representation – independent from the machine speed. Thus, the operator keeps full control over the entire production, even during critical phases like make-ready time or start/stop.”

“The function of digital strobe+ is to not only accurately counting repeats, labels and missing labels in total and per lane, but to also detects matrix residues across the entire web width. This eliminates the usage of expensive and unreliable sensors and the necessity of cumbersome and time-consuming sensor adjustment. By choosing the additional option of digital strobe++, TubeSan becomes a full grown print inspection system, which is able to detect print defects and register variations below one millimetre,” he explained.

Following the acquisition of AccuWeb by BST’s American subsidiary, the BST product range is strengthen by AccuWeb’s sophisticated web guiding systems. At the show, besides the AccuWeb solutions, BST highlighted digital commander, sensors and networking solutions for the visitor’s web guiding tasks. Asked about the response during the show, he said “Labelexpo Europe has been fantastic for BST Sayona. We have had several enquiries from international as well as Indian player.”
