Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
A printing system that carries out a main scan,
which reciprocates a print head relative to a printing
medium, and forms a raster line, which is a row of dots
aligned in a main scanning direction, so as to print an
image on said printing medium, wherein said print head comprises a plurality of
nozzles which form an identical type of dots on a raster
line in one main scan.
Claim 2
Dependent Claim
42 words
A printing system in accordance with claim 1,
wherein said plurality of nozzles are arranged at a
predetermined interval k1 in the main scanning
direction, said predetermined interval being an integral
multiple of a pitch of pixels in the main scanning
direction.
Claim 3
Dependent Claim
42 words
A printing system in accordance with claim 1 or
2, said printing system further comprising: a drive unit which controls actuation of said
plurality of nozzles and causes said plurality of
nozzles to record dots at different positions on said
raster line.
Claim 4
Dependent Claim
66 words
A printing system in accordance with claim 1, 2
or 3, wherein said plurality of nozzles are arranged to
satisfy a relationship in which a predetermined interval
k1 of said plurality of nozzles in the main scanning
direction expressed as the pitch of pixels in the main
scanning direction is prime to a number of said
plurality of nozzles N1 aligned in the main scanning
direction.
Claim 5
Dependent Claim
36 words
A printing system in accordance with claim 3 and
4, wherein said drive unit drives said plurality of
nozzles simultaneously at a specific timing to record
dots in every N1-th pixel in the main scanning
direction.
Claim 6
Dependent Claim
56 words
A printing system in accordance with any
preceding claim, wherein said print head comprises
plural sets of said plurality of nozzles, said plural
sets being arranged at a given interval in a
predetermined direction crossing the main scanning
direction, said given interval being an integral
multiple k2 of a pitch of pixels in the predetermined
direction.
Claim 7
Dependent Claim
47 words
A printing system in accordance with claim 6,
wherein said print head comprises said plural sets of
said plurality of nozzles that are arranged to satisfy a
relationship in which the integral multiple k2 and a
number of said plural sets N2 are prime to each other.
Claim 8
Dependent Claim
75 words
A printing system in accordance with claim 7,
said printing system further comprising: a sub-scanning unit that carries out a sub-scan,
which shifts said printing medium relative to said print
head by a predetermined amount of feed in a sub-scanning
direction or in the predetermined direction crossing the
main scanning direction every time when one raster line
is formed, said predetermined amount of feed being N2
times the pitch of pixels in the sub-scanning direction.
Claim 9
Independent Claim
160 words
A method of carrying out a main scan, which
reciprocates a print head relative to a printing medium,
and forms a raster line, which is a row of dots aligned
in a main scanning direction, so as to print an image on
said printing medium, wherein said print head comprises a plurality of
nozzles which form an identical type of dots on a raster
line in one main scan and are arranged to satisfy a
relationship in which a predetermined interval k1 of
said plurality of nozzles in the main scanning direction
expressed as a pitch of pixels in the main scanning
direction is prime to a number of said plurality of
nozzles N1 aligned in the main scanning direction, said method comprising the steps of: (a) driving said print head in the main scanning
direction; and (b) driving said plurality of nozzles
simultaneously at a specific timing to record dots in
every N1-th pixel in the main scanning direction.
