Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
132 words
An ink jet recording method in which a plurality of inks different in color are used to record a color image for a unitary picture element, said method comprising the steps of: printing a first portion of a unitary picture element with at least one ink low in permeability; and printing a second portion of said picture element with at least one ink high in permeability, wherein the picture element is a dot matrix comprising low-permeable ink dots printed with said at least one ink low in permeability and high-permeable ink dots printed with said at least one ink high in permeability, and wherein in the picture element the at least one ink low in permeability and the at least one ink high in permeability mix with and diffuse into each other.
Claim 2
Dependent Claim
132 words
An ink jet recording method in which a plurality of inks different in color are used to record a color image for a unitary picture element, said method comprising the steps of: printing a first portion of a unitary picture element with at least one ink low in permeability; and printing a second portion of said picture element with at least one ink high in permeability, wherein the picture element is a dot matrix comprising low-permeable ink dots printed with said at least one ink low in permeability and high-permeable ink dots printed with said at least one ink high in permeability, and wherein in the picture element the at least one ink low in permeability and the at least one ink high in permeability mix with and diffuse into each other.
Claim 3
Dependent Claim
21 words
An ink jet recording method of claim 1, wherein said high-permeable ink dots are recorded adjacent to said low-permeable ink dots.
Claim 4
Dependent Claim
28 words
An ink jet recording method of claim 1, wherein a ratio in number of said high-permeable ink dots to said low-permeable ink dots is from 50% to 200%.
Claim 5
Dependent Claim
53 words
An ink jet recording method of claim 1, wherein a first imaged portion of said unitary picture element comprises lapped ink dots formed by lapping said low-permeable ink dots and said high-permeable ink dots on each other, and a second non-imaged portion of said unitary picture element that is not printed with ink.
Claim 6
Dependent Claim
28 words
An ink jet recording method of claim 4, wherein a ratio of area of said second non-imaged portion to said first imaged portion is from 0% to 100%.
Claim 7
Dependent Claim
18 words
An ink jet recording method of claim 1, wherein said ink low in permeability is a black ink.
Claim 8
Dependent Claim
24 words
An ink jet recording method of claim 6, wherein said unitary picture element is located at a boundary of image regions different in color.
Claim 9
Dependent Claim
34 words
An ink jet recording method of claim 1, wherein said printing with said at least one ink low in permeability is prior to said printing with said at least one ink high in permeability.
Claim 10
Dependent Claim
21 words
An ink jet recording method of claim 8, wherein said high-permeable ink dots are recorded adjacent to said low-permeable ink dots.
Claim 11
Dependent Claim
31 words
An ink jet recording method of claim 8, wherein said picture element comprises lapped ink dots formed by lapping said low-permeable ink dots and said high-permeable ink dots on each other.
Claim 12
Dependent Claim
34 words
An ink jet recording method of claim 1, wherein said printing with said at least one ink high in permeability is prior to said printing with said at least one ink low in permeability.
Claim 13
Dependent Claim
21 words
An ink jet recording method of claim 11, wherein said high-permeable ink dots are recorded adjacent to said low-permeable ink dots.
Claim 14
Dependent Claim
31 words
An ink jet recording method of claim 11, wherein said picture element comprises lapped ink dots formed by lapping said low-permeable ink dots and said high-permeable ink dots on each other.
Claim 15
Dependent Claim
25 words
An ink jet recording method of claim 1, wherein said ink low in permeability is of a darker color than said ink high in permeability.
Claim 16
Dependent Claim
21 words
An ink jet recording method of claim 1, wherein said unitary picture element is part of a line or character image.
Claim 17
Dependent Claim
73 words
An ink jet recording method of claim 1, wherein said at least one ink low in permeability is up to 0.5 ml/m 2 ms 1/2 in absorption coefficient (Ka) and in a range of 50 msec to 200 msec in wet time (Tw), and said at least one ink high in permeability is up to 1.0 ml/m 2 ms 1/2 in absorption coefficient (Ka), and up to 20 msec in wet time (Tw).
Claim 18
Dependent Claim
