Profiles:
The
BT series system employs a cylinder configuration based on single-sized
plate/blanket cylinders of standard diameter, a common impression cylinder of
triple-size diameter, and transfer cylinders of quadruple size diameter. This
provides outstanding printability on stock ranging from thin paper to board.
Since the second color is printed after the first color is complete, no
printing problems or defects occur between cylinders.
Impression
cylinders and transfer cylinders with a large radius of curvature allow the
printing paper to contact the entire cylinder surface without unwanted stress.
Sheet transfer is flat and smooth.
The
BT series models use a minimum of cylinders, thus minimizing the number of
transfers (Just two times during a four-color printing process) for extremely
accurate registration.
The
transfer of printed sheets in the delivery section is performed after printing
is completed in the final unit. Ink simply won't smudge, even when the entire
surface is covered in ink
