Abstract
Abstract A thermal transfer type printing apparatus first transfers white or transparent ink on a recording paper and thereafter transfers ink of a predetermined color on top of the recording made by the white or transparent ink, so that the recording is always made by the ink of the predetermined color on a smooth surface even when the surface of the recording paper is not smooth.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
244 words
A thermal transfer type printing apparatus comprising: a thermal printing head; a recording paper; an ink transfer sheet comprising first and second ink portions and placed between said thermal printing head and said recording paper, said first ink portion being coated with white or transparent ink, said second ink portion being coated with ink of a predetermined color; input terminal means applied with input data related to an image which is to be printed on said recording paper; and control means for controlling heating times of said thermal printing head responsive to said input data so as to heat and melt the ink of said ink transfer sheet on said recording paper depending on said input data, said thermal printing head under control of said control means making recordings by first transferring the white or transparent ink of said first ink portion on said recording paper depending on said input data and thereafter transferring the ink of the predetermined color of said second ink portion on top of the recordings made by the white or transparent ink of said first ink portion depending on said input data, said control means controlling the heating times of said thermal printing head so that an area of each recording made on said recording paper with the white or transparent ink of said first ink portion is greater than an area of a corresponding recording made with the ink of the predetermined color of said second ink portion.
Claim 2
Dependent Claim
244 words
A thermal transfer type printing apparatus comprising: a thermal printing head; a recording paper; an ink transfer sheet comprising first and second ink portions and placed between said thermal printing head and said recording paper, said first ink portion being coated with white or transparent ink, said second ink portion being coated with ink of a predetermined color; input terminal means applied with input data related to an image which is to be printed on said recording paper; and control means for controlling heating times of said thermal printing head responsive to said input data so as to heat and melt the ink of said ink transfer sheet on said recording paper depending on said input data, said thermal printing head under control of said control means making recordings by first transferring the white or transparent ink of said first ink portion on said recording paper depending on said input data and thereafter transferring the ink of the predetermined color of said second ink portion on top of the recordings made by the white or transparent ink of said first ink portion depending on said input data, said control means controlling the heating times of said thermal printing head so that an area of each recording made on said recording paper with the white or transparent ink of said first ink portion is greater than an area of a corresponding recording made with the ink of the predetermined color of said second ink portion.
Claim 3
Dependent Claim
36 words
A thermal transfer type printing apparatus as claimed in claim 1 in which said control means supplies pulse signals having mutually different pulse widths so as to control the heating times of said thermal printing head.
Claim 4
Dependent Claim
35 words
A thermal transfer type printing apparatus as claimed in claim 1 in which said second ink portion of said ink transfer sheet includes first, second and third portions respectively coated with ink of three colors.
Claim 5
Dependent Claim
28 words
A thermal transfer type printing apparatus as claimed in claim 3 in which said first, second and third portions are respectively coated with yellow, magenta and cyan ink.
Claim 6
Dependent Claim
66 words
A thermal transfer type printing apparatus as claimed in claim 3 in which said first ink portion and said first, second and third portions of said second ink portion are arranged on said ink transfer sheet in a sequence in correspondence with a sequence with which the recordings are made on said recording paper by the white or transparent ink and the ink of three colors.
Claim 7
Dependent Claim
29 words
A thermal transfer type printing apparatus comprising: a thermal printing head comprising a plurality of heating resistors; a recording paper; an ink transfer sheet comprising first, second, third and
Claim 8
Dependent Claim
29 words
A thermal transfer type printing apparatus comprising: a thermal printing head comprising a plurality of heating resistors; a recording paper; an ink transfer sheet comprising first, second, third and
Claim 9
Dependent Claim
25 words
A thermal transfer type printing apparatus as claimed in claim 6 in which said second through fourth strobe pulse signals have mutually identical pulse widths.
Claim 10
Dependent Claim
50 words
A thermal transfer type printing apparatus as claimed in claim 6 in which said strobe pulse generating means comprises delay means for delaying said load and latch pulse signal, and monostable multivibrator means supplied with an output of said delay means for generating said first through fourth strobe pulse signals.
Claim 11
Dependent Claim
28 words
A thermal transfer type printing apparatus as claimed in claim 6 in which said three color signals comprise a yellow signal, a magenta signal and a cyan signal.
Claim 12
Dependent Claim
56 words
A thermal transfer type printing apparatus as claimed in claim 6 in which said first through fourth ink portions are arranged on said ink transfer sheet in a sequence in correspondence with a sequence with which the recordings are made on said recording paper by the white or transparent ink and the ink of three colors.
