Q.I. Press Intelligent Register System
New Printing Press Equipment Used Web Offset Presses
The
Q.I Press Intelligent Register System (IRS) camera with CCD technology views the printed side of the web and, as
the press starts up, searches for register marks representing all print
colours as well as a possible 2 PMS colours. The printed register marks are
almost invisible to the naked eye; each point measures 0.2 x 0.2 mm and can
be positioned within a free space of 5x5 mm. Because these register marks
are almost invisible, they can be placed on the editorial pages, avoiding
paper loss through extra margins. After starting up the press, the CCD
camera immediately measures any discrepancies between actual and target
positions of the register marks. These measurements are converted into
controls to correct the differences between the register marks in lateral
and circumferential directions. Within seconds, this results in
auto-make-ready. According to feedback from our clients on the performance
of the IRS, this is faster than any other system on the market.
During production the IRS continuously monitors and adjusts the target positions of the register marks. The IRS cameras are fitted with a telecentric lens that does not require a fixed focus distance. That is why the IRS cameras are not affected by an undulating web, which means that they can be installed immediately after the last printing tower. Alternative systems are usually positioned after the chilling rollers on rotary presses, which is why these always react later than the IRS.
