In Case The Heater Temperature Is Too Low - MIMAKI JV33-260 Operation Manual

In case the heater temperature is too low

When solvent ink is used, this may result in printing failures such as beading or banding if the heater temperature
or the ink acceptable amount (the ink limit) is too low.
Beading is a phenomenon that adjacent dots attract each other and join. Beading causes speckled patterns or
stripes along printing passes (banding.)
Example of beading
The area in 100% magenta looks fine. Generally, the area in 70-100% single color is easily affected by the
unevenness of media feed rate. The print shown here, free from unevenness of color in the vicinity of 100%
magenta area, signifies that media feeding has been adjusted properly.
In the blue area (100% magenta + 100% cyan), however, speckled patterns and banding occur. This banding is a
result of beading. If heater temperatures are low or the ink capacity (ink limit) of the media is low, the first dot
does not solidify before the second dot lands on the media. As a result, dots bond to each other and unevenness
or banding occurs.
In order to avoid beading, it is recommended to raise the heater temperatures, to raise the ink capacity (ink limit)
of the media, to adjust the ink volume per dot for the media, to increase the number of printing passes and
decrease the ink amount for one shot, and/or to gain time by scan wait. Change media if none of the above-
mentioned measures works to prevent beading.
