Abstract
In an ink jet recording method and an apparatus for forming an information pattern by synthesizing record patterns by ink droplets emitted from two ink ejection nozzles, a seam of the patterns is defined by those edges of the patterns which have been less deflected.

An ink jet recording method for recording a continuous pattern by the synthesis of two record patterns split in a direction of deflection of ink droplets, wherein said two split record patterns are formed by deflecting first ejected ink droplets and second ejected ink droplets individually from each other and respectively in opposite senses of the ink droplet deflection direction, and said two split record patterns are seamed together along their edges which are defined by the ink droplets deflected with a smaller angle.
An ink jet recording apparatus comprising two record heads, each of said two record heads including an ink nozzle for ejecting ink droplets therefrom, ink droplet deflection means for deflecting the ejected ink droplets only in a deflection area of one side with respect to a direction of ejection of the ink droplets and a collector for collecting non-deflected ink droplets, wherein said two record heads are arranged such that record dots adjacent to a deflection base line are formed by the ink droplets deflected with a smaller angle by said two record heads respectively, and said deflection areas of said two record heads are opposite to each other with respect to said deflection base line.
An ink jet recording method for recording a continuous pattern by the synthesis of first and second record patterns split in a direction of deflection of ink droplets, wherein said first record pattern is formed by a first record head to control the deflection of first ejected ink droplets in a deflection area of one side with respect to a direction of ejection of said first ink droplets, said second pattern is formed by a second record head to control the deflection of second ejected ink droplets in a deflection area of one side with respect to a direction of ejection of said second ink droplets, said deflection areas of said first and second record heads being opposite to each other, and said first and second split record patterns are seamed together along their edges which are defined by those ink droplets of said first and second ink droplets which are deflected with a smaller angle by said first and second record heads, respectively.
An ink jet method of recording a prescribed pattern on a recording medium comprising the steps of:
- a. directing a first stream of ink droplets toward a first portion of said recording medium and controllably deflecting said first stream of ink droplets in a first angular direction so as to cause the ink droplets in said first stream to be deposited on only said first portion of said recording medium;
- b. directing a second stream of ink droplets toward a second portion of said recording medium and controllably deflecting said second stream of ink droplets in a second angular direction, opposite to said first angular direction, so as to cause the ink droplets in said second stream to be deposited only on said second portion of said recording medium;
- and wherein
- an edge of said first portion of said recording medium abuts an edge of said second portion of said recording medium, and said first and second streams of ink droplets are deflected in such a manner that those ink droplets of said first stream which have been controllably deflected through the smallest angle of deflection for said first stream are deposited along said edge of said first portion of said recording medium, and those ink droplets of said second stream which have been controllably deflected through the smallest angle of deflection for said second stream are deposited along said edge of said second portion of said recording medium, whereby said prescribed pattern is recorded on the abutting first and second portions of said recording medium.
An ink jet recording apparatus for recording a prescribed pattern on a recording medium comprising:
- first means for directing a first stream of ink droplets toward said recording medium and for controllably deflecting said first stream of ink droplets in a first angular direction so as to cause the ink droplets in said first stream to be deposited on only a first portion of said recording medium;
- and
- second means for directing a second stream of ink droplets toward said recording medium and for controllably deflecting said second stream of ink droplets in a second angular direction, opposite said first angular direction, so as to cause the ink droplets in said second stream to be deposited on only a second portion of said recording medium;
- and wherein
- the deflection of said first and second streams of ink droplets controlled by said first and second means, respectively, is such that an edge of the pattern formed by the deposited ink droplets of said first stream on said first portion of said recording medium abuts an edge of the pattern formed by the deposited ink droplets of said second stream on said second portion of said recording medium, and said first and second streams of ink droplets are deflected in such a manner that those ink droplets of said first stream which have been controllably deflected by said first means through the smallest angle of deflection for said first stream are deposited along said edge of the pattern formed in said first portion of said recording medium, and those ink droplets of said second stream which have been controllably deflected by said second means through the smallest angle of deflection for said second stream are deposited along said edge of the pattern formed on said second portion of said recording medium.
