5.3 SET THE CORRECT DISTANCE ADJUST (STEP)
Obtaining constant printing quality on a wide-format Piezo inkjet printer is not only determined by the working
environment, the RIP, the profiles, the inks and the media which are used. One of the key factors for
obtaining constant output quality is the correct distan
ce adjustment, also called step, on your Mutoh inkjet
printer.
5.3.1 Basics about the step
Every image is printed in several print passes. After every pass, the media is fed an amount of millimetres.
When the step is not set correctly, the passes will overlap each other or will not be printed precisely next to
each other, which results in white bands between two print passes.
Therefore a function, distance adjust (or step), is added to the menu to control this feed operation.
Refer to the table below for visual support
UNDERFEED = step between the print passes
is too small which results in the passes to
overlap each other.
OVERFEED = step between the print passes is
too large which results in the passes to be
printed too far from each other.
Notes
It is recommended to start printing with a step of 100.00% and to adjust it afterwards. Once a step is set for
a particular media it will not change on following conditions:
The step is only applicable on the printer in question and not interchangeable.
The media manufacturer does not change any specifications (especially backing) of the media.
The unwinder/winder 100 is used.
Please refer to the next chapter to know where and how to change the step.
