<How to decide a correction value>
(1)
Head position adjustment correction value
•
Observe the H POS ADJ pattern with a loupe and decide a cor-
rection value to match the reference color (BK) and color to be
adjusted.
•
A unit of correction value is 1/8 dot (720doi) and a range of
correction is -256 to +255. A correction value of plus (+) ap-
proaches a color to be adjusted to the home position and a cor-
rection value of minus (-) keeps away a color to be adjusted from
the home position.
(2)
Ink position adjustment correction value
•
Observe INK POS ADJ pattern with a loupe and decide a cor-
rection value to match the reference line of outward journey (left
line) and home ward journey (right line).
•
A unit of correction value is 1/8 dot (720doi)and a range of cor-
rection is -256 to +255. A correction value of plus (+) approaches
a color to be adjusted to the home position and a correction value
of minus (-) keeps away a color to be adjusted from the home
position.
