Abstract: UN APARATO DE IMPRESION Y UN METODO DE REGISTRO DE IMPRESIONES QUE PERMITE EL REGISTRO DE IMPRESIONES ENTRE UNA EXPLORACION HACIA ADELANTE Y UNA HACIA ATRAS DE UN CARTUCHO DE CABEZAS (1) O (4) ENTRE UNA PLURALIDAD DE CARTUCHOS DE CABEZAS SIN CAUSAR MOLESTIAS AL USUARIO Y DE MANERA SENCILLA. MEDIANTE LA EXPLORACION HACIA ADELANTE Y HACIA ATRAS DEL CARTUCHO DE CABEZAS (1) O (4), SE PUEDEN IMPRIMIR UNA PLURALIDAD DE DISEÑOS, SIENDO EL MOMENTO DE INICIO DE LA IMPRESION DE LA EXPLORACION HACIA ATRAS RETARDADO UNA CANTIDAD DE TIEMPO PREDETERMINADA RESPECTO AL DE LA EXPLORACION HACIA ADELANTE. ESTOS PATRONES PUEDEN VARIAR UNA SUPERFICIE A CUBRIR POR LOS PUNTOS FORMADOS AL IMPRIMIR DEPENDIENDO DE LA CANTIDAD DE RETARDO. POR OTRO LADO, LA PLURALIDAD DE PATRONES SON LEIDOS OPTICAMENTE A UNA DENSIDAD MEDIA. SEGUN ESTO EL MOMENTO EN QUE LA DENSIDAD MEDIA DE LECTURA ALCANZA EL MAXIMO SE FIJA COMO LA CONDICION DEL REGISTRO DE IMPRESION.

Abstract: PROBLEM TO BE SOLVED: To execute aligning of a printing position without disturbing a user, by a method wherein an operation of aligning the printing position is executed based on an optical characteristic which is obtained by measuring corresponding to a plurality of relative shift amounts of printing positions between first printing and second printing. SOLUTION: Nine kinds of print patterns are printed and optical reflection densities thereof are measured (S121). It is judged whether the greatest OD value of the measured reflection optical densities is in a range of 0.7-1.0. When it is in the range, the next step of S123 is executed (S122). When it is not, the print patterns are changed (S125). At that time, when the value is greater than 1.0, the print pattern is changed to one whose dot number is thinned out to two third of the original pattern, then the operation is returned to the step of S121.
