Recommendations and expectations
19.1
Print speed
Printing at 18 m/min (12ips) will reduce the chance of the bag hitting the print head. Particularly when
exiting the print zone
19.2
Web/substrate cleaning
We generally recommend cleaning the substrate using a vacuum cleaning device. This will reduce the
amount of fibres entering the print engine, contaminating the print head, wiper roller and cap.
19.3
Mid job cleaning frequency
It is difficult to recommend a general setting of the mid job cleaning interval, however if the bags are
dust/fibre free, 100-200 bags between maintenance cycles should be achievable.
19.4
Printing on wood
Print on plain wood works well. However, depending on the grain of the wood, the ink may bleed a bit into
the fibres, but we find that most wood used for wine gift boxes works well.
For very detailed artwork we see enhanced quality after applying a clear coating before printing. The
coating can be purchased at Trojanlabel.
19.5
Avoid Vacuum active under print head
It is important not to have vacuum suction directly under the print head, as this can dry out the print head.
19.6
Expectations
The operator will have optimal print conditions by following the above guidelines. This will ensure a good
print quality, however due to the great variance in substrates we cannot guarantee that some smearing will
never occur.
