The "Scandiff" is an "offline" used for comparison of digital images. He compares an original file provided by the client (or PDF Bitmap) of art that will be printed with a scanned image through a "scanner", the material in the printer. The system compares every detail of these images, and once approved, the printer can start printing service in production rate.
 
It can be used for three different types of controls:
 
· PDF to PDF;
· PDF to Bitmap;
· Bitmap to Bitmap
