Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 52 words
An ink jet recording method for effecting polychromatic recording by the use of inks of two or more colors, characterized by the process of repeating one-line printing by color in conformity with the number of colors used at least on the same line, and forming one line of a polychromatic recorded portion.
Claim 2
Dependent Claim 52 words
An ink jet recording method for effecting polychromatic recording by the use of inks of two or more colors, characterized by the process of repeating one-line printing by color in conformity with the number of colors used at least on the same line, and forming one line of a polychromatic recorded portion.
Claim 3
Dependent Claim 104 words
An ink jet recording apparatus having a recording head capable of discharging inks of two or more colors in conformity with recording information, and means for causing said recording head to scan relative to a recording medium, said apparatus being capable of accomplishing polychromatic recording, characterized by means for changing a mode in which one-line printing by color is repeated in conformity with the number of colors used at least on the same line to thereby form one line of a polychromatic recorded portion, and a mode in which one line of a polychromatic recorded portion is formed in one scan by polychromatic printing.
Claim 4
Dependent Claim 104 words
An ink jet recording apparatus having a recording head capable of discharging inks of two or more colors in conformity with recording information, and means for causing said recording head to scan relative to a recording medium, said apparatus being capable of accomplishing polychromatic recording, characterized by means for changing a mode in which one-line printing by color is repeated in conformity with the number of colors used at least on the same line to thereby form one line of a polychromatic recorded portion, and a mode in which one line of a polychromatic recorded portion is formed in one scan by polychromatic printing.
Claim 5
Independent Claim 60 words
A method of ink jet recording an image including a polychromatic portion of at least two colors, including the step (A) of forming a polychromatic part of said image by printing within said part in a single color, and successively repeating the step (A) one or more times for each additional color in accordance with the required number of colors.
Claim 6
Independent Claim 60 words
A method of ink jet recording an image including a polychromatic portion of at least two colors, including the step (A) of forming a polychromatic part of said image by printing within said part in a single color, and successively repeating the step (A) one or more times for each additional color in accordance with the required number of colors.
Claim 7
Dependent Claim 15 words
A recording method according to claim 3, wherein said part is a line of information.
Claim 8
Dependent Claim 78 words
An ink jet recording apparatus comprising a recording head capable of operating in a first mode in which a polychromatic image part is recorded by successively printing a single color for as many times as the number of colors required, and said recording head is capable of operating in a second mode in which a polychromatic image part is recorded in one scan by polychromatic printing, and further comprising means for changing between said first and second modes.
Claim 9
Dependent Claim 78 words
An ink jet recording apparatus comprising a recording head capable of operating in a first mode in which a polychromatic image part is recorded by successively printing a single color for as many times as the number of colors required, and said recording head is capable of operating in a second mode in which a polychromatic image part is recorded in one scan by polychromatic printing, and further comprising means for changing between said first and second modes.
