Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
127 words
An ink jet recording method using a number of ejection outlets for ejecting ink, arranged in a line, said method comprising the steps of: grouping a number of ejection outlets into a plurality of groups in which the ejection outlets eject the ink substantially simultaneously, wherein ejection outlets in each group of the plurality of groups define an area containing all of the ejection outlets in a respective group, and respective areas of adjacent groups of the plurality of groups partially overlap, and respective areas of non-adjacent groups of the plurality of groups do not overlap; and supplying driving signals in such an order that ejection outlets in adjacent groups are driven such that adjacent groups sequentially eject ink and corresponding areas of the adjacent groups overlap.
Claim 2
Dependent Claim
127 words
An ink jet recording method using a number of ejection outlets for ejecting ink, arranged in a line, said method comprising the steps of: grouping a number of ejection outlets into a plurality of groups in which the ejection outlets eject the ink substantially simultaneously, wherein ejection outlets in each group of the plurality of groups define an area containing all of the ejection outlets in a respective group, and respective areas of adjacent groups of the plurality of groups partially overlap, and respective areas of non-adjacent groups of the plurality of groups do not overlap; and supplying driving signals in such an order that ejection outlets in adjacent groups are driven such that adjacent groups sequentially eject ink and corresponding areas of the adjacent groups overlap.
Claim 3
Dependent Claim
18 words
