Laser measurement system TIR

for production linesautomatichigh-speed

The TIR measurement system is the winner of the International print & innovation award 2015. It analyses the quality of the printing sleeve or cylinder by measuring the ‘3D landscape’ of the surface. This information gives a thorough insight on the condition of the printing sleeve or the cylinder. With that, the TIR builds up a record of the exact condition of each printing sleeve or cylinder in stock. Subsequently the printing sleeves can be placed in the press with the right pre-settings. Analyzing and interpreting the data The measured data is analyzed in both horizontal and vertical direction and gives: • An overall average • A maximum and minimum • Out-of-roundness • Topography of the complete sleeve The actual measured data is added to the record of the sleeve. The operator can also print out a quality report of the topography of the sleeve. A high-quality laser takes the measurements with an accuracy of 5 microns. The accuracy of the TIR system allows monitoring the distance between the guiding rail and the full length of the axis. It calibrates any irregularities to ensure precision on micron level. A full report is generated to keep track of any irregularities. The operator can pre-set specific tolerances that define whether the sleeve is still usable. The ability to check the exact condition of each sleeve is essential for high-speed production with minimum pressure settings on the press. Worn out or damaged sleeves are easily detected, which prevents bad quality sleeve related downtime in the printing presses. It also helps to create an inventory of sleeves that are fit for use.
