What is beading ?
Beading is a phenomenon that adjacent dots attracts 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.
Fine looking print
In the blue area (100% m 100% cyan), however, speckled patterns and banding occur. This band-
ing 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.
