Cover Story
Introducing the latest scanning technologies with the new AniCAM-HD
geometry is captured faultlessly. Visual feedback, through the LED control interface and onscreen alerts, allows the user to know they are taking the best possible measurements with the perfect settings, taking the user interpretation out of the equation.
D uring the history of anilox
measurement, there have been many different ways to obtain an indication of anilox volume and, in particular, suitability for press: theoretical, where the cell opening and depth were used to calculate a volume; ink drawdown, where a known volume of ink was applied to an anilox and this provided a calculation of available volume; and, eventually, electronic microscopes, where the volume can be calculated using the geometry observed. Unfortunately, these all gave a different value and, therefore, the printer had to base their ink rheology calculations on the methods they employed to obtain the volume.
STANDARDISATION
Introducing a standard for volumetric measurement, currently there is no standard for anilox volume measurement. Anilox measurement has been an emotive subject
for many years, as printers have been unsure of the measurement values from different suppliers and also the tracking of wear and damage during the life of their anilox inventory. Troika has been working to provide a known volume, regardless of the manufacturer, which can be relied upon and is repeatable, even to staff with little training. The AniCAM-HD allows printers to make the measurement independently of the user by automating the measurement process.
WHY IS THE ANICAM-HD DIFFERENT? The launch of the AniCAM-HD introduced a patented technology called PIXELOC. This provides a closed-loop calibration and measurement check, so that, regardless of the cell geometry or ceramic condition, the exact volume measurement can be made. The benefit to the printer is that they can rely on the measurements taken. Using micro-steps of just 250nm, means that all cell
With upgraded optics and on-board processing, the visualisation of the anilox is improved by use of a new series of sensors and optics, making use of modern technology improvements. For the user, this means a clearer, more defined image is taken, which further improves the readability and reliability of the measurements. New lighting enables all anilox surface technologies to be scanned without special adjustment, including the latest engraving styles to be successfully scanned without compromise. All cell geometry is captured automatically, removing the interpretation of measurement from the user. This includes; volume, depth, line screen, engraving angle, wall and opening values. The enhanced operation allows for reporting on multiple regions of the anilox, with delta variance values and database software to allow the printer to confirm suitability and track wear in addition the auto scan features make scanning easier for the user, as they progress across the anilox surface. Using these enhanced technologies and simplifying the user interface has made the AniCAM-HD unrivalled in the measurement of anilox, flexoplate and gravure and will allow printers to reduce time and waste created in extended make-ready due to unknown anilox volumes and conditions.
