Duplo Offers Patented Image-shift Detection System
The CCD scanner on the Duplo machine translates the image position into numerics by reading a registration mark printed on each sheet. It uses this data to make minor on-the-fly adjustments automatically to the cutting, slitting and creasing positions. As the image position changes from sheet to sheet, the adjustments are calibrated automatically, ensuring that not only the finished document is to the exact physical dimension programmed, but that the image position is consistent from sheet to sheet.
The Duplo DC-645 CCD scanner scans a document
with a barcode for job recall, and a registration mark
for image-shift compensation.
Duplo currently offers this technology on its Slitter/Cutter/Creaser product line and nearline SCC Bookletmaking systems. It’s standard on the DC-645 and on the Bookletmaker, but optional on the DC-615, which is a light production model similar to the DC-645. The technology is not offered with any other Duplo solutions today, and cannot be retrofitted to other Duplo machines.
Si Nguyen of Duplo states, “The image-shifting feature is one of the main reasons why our clients place their investment in Duplo. Customers that use the feature are hooked on it, as it ensures peace of mind that the finished product is consistent.” He also added, “Look for future Duplo Slitter/Cutter/Creaser models with improved speed and additional capabilities in 2010.”
OK, so it’s awesome, but there must be a drawback somewhere. I asked, and the only drawback is that productivity is decreased slightly, as it takes a split second longer to verify image registration from sheet to sheet. That makes sense. I guess given the potential savings on time and materials from reprints and quality issues, it’s worth the wait.
Now that I know about this image shifting problem, I’m curious to know what other finishing machine manufacturers are doing to address the problem. I guess you’ll have to watch my blog for the answer.
