EPSON Stylus Color 600

The difference between Full-Overlap Micro-Weave and Part line Overlap Micro-Weave are
following;


Full-Overlap Micro-Weave:
Printing is performed, judging if nozzles are even or odd dot by 2 different dots with all
different rasters.
 
Part line Overlap Micro-Weave:
After particular nozzles(only#1, and #6 in the figure2-7) are determined as overlap nozzles,
even or odd dot will be determined like Full-overlap Micro-Weave does.
(Forward Overlap Nozzle is determined as even and backward nozzle is odd.)
Also, nozzles other than particular nozzles can print at even and odd dot just by one
nozzle.
1) Overlap Nozzle
2) Nozzle other than Overlap nozzle : Head drive frequency is twice as much as overlap nozzle.
Usually, the firmware changes over automatically these full overlap Micro-Weave, Part line Overlap
Micro-Weave, and ordinal Micro-weave according to the selection of resolution. Also, when these three
printing modes are performed by the Stylus Color 600, the printer performs top and bottom margin
process in order to control the overprinting volume as little as possible.
2-6
: Head drive frequency is driven half of the ordinal one like 2)
