The system has a programmable width conveyor system, set by the board width parameter, in the
product file. The rails transport the board, using belts, from the upline machine into the printer,
where the board is positioned, clamped, and printed. After printing, the board is transferred, using
the same belts, to the downline machine.
An option is available for heavy boards, the transport rails can transport boards weighing up to 6kg.
This is achieved using an extra drive pulley on each rail and flat profiled transport belts.

16.1.1 Board Clamping Arrangements
The transport rails can be fitted with one of the following board clamping arrangements:
●
250mm or 500mm Board Clamps (foiled)
●
250mm or 500mm Foil-less Clamps
●
Board Snugger Assembly
Board clamps are used to support boards using the foils fitted to the edge of the clamp. This gives
additional support to the top of the board but the printable image must not extend to the area occu-
pied by the foils.
Foil-less clamps are utilized for thin pliable boards where there is a requirement to print close to the
board edge. The foil-less clamps are assisted with the use of a vacuum box beneath the product
board.
Board snuggers are an alternative to the standard board clamps and are utilized when there is a re-
quirement to print close to the board edge.
