Disclosed is a printing apparatus that performs printing by using inks of plural colors including a white color, which includes a first nozzle group that ejects an ink of one color including a white color and at least one color other than the white color, and a second nozzle group that ejects the inks of plural colors. An image formed by the first nozzle group is an undercoat layer or an overcoat layer of an image formed by the second nozzle group.

Printing using inks of plural colors including white color

Disclosed is a printing apparatus that performs printing by using inks of plural colors including a white color, which includes a first image forming unit that forms a first image, and a second image forming unit that forms a second image such that at least a part of the second image overlaps the first image. The second image forming unit forms at least a part of a section of the second image, which overlaps the first image, by using only a white ink, and forms at least a part of a section of the second image, which does not overlap the first image, by using inks of a white color and at least one color other than the white color.

A printing apparatus executes printing on a transparent print medium using a plurality of color ink including white ink. The printing apparatus includes: a head having a first nozzle group ejecting the plurality of color ink to form a color image and a second nozzle group ejecting the white ink and at least one kind of ink other than the white ink to form a toning white image, which is an adjusted white image; and a controller controlling the head to form a first color image, a first toning white image, a second toning white image set independently from the first toning white image, and a second color image in this order on one surface of the print medium.

Printing using plurality of color ink including white ink

An apparatus includes: a first nozzles for ejecting a first fluid are lined up in a predetermined direction; a second nozzles for ejecting a second fluid are lined up in the predetermined direction; and a control unit performs an ejecting operation of ejecting fluid from the nozzles, wherein the control unit forms an image on a medium in one of a first mode of forming a main image with the first fluid and a second mode of forming the main image and a background image with the second fluid to be overlapped, forms the main image using a certain nozzle group in the first nozzles when the main image is formed in the first mode, and forms the main image using the same nozzle group as the certain nozzle group when the main image is formed in the second mode.

A test chart used for color calibration includes: the number of patches of a first color; and the number of patches of a second color. The number of patches of the first color is determined on the basis of the degree of variation in the colorimetric value of the first color in a color space on a medium, and the number of patches of the second color is determined on the basis of the degree of variation in the colorimetric value of the second color in the color space on the medium.

Method of determining number of patches

A print and colorimetry instructing section delivers an exclusive-use start instruction to start exclusive use of the printer prior to delivery of the printing instruction and the colorimetry instruction, the print and colorimetry instructing section delivering an exclusive-use canceling instruction to cancel the exclusive use of the printer at a predetermined time subsequent to delivery of the exclusive-use start instruction. The printer carries out only a process according to the instruction from the print and colorimetry instructing section having delivered the exclusive-use start instruction until accepting a predetermined exclusive-use canceling instruction subsequent to acceptance of the exclusive-use start instruction.

Printer control system, printer control method and printer

A printing calorimetric control device of the present invention is configured to comprise a reception section which receives a designation for a colorimetry position on a predetermined image; a printing control section which prints an image on a print medium on the basis of image data which represent the predetermined image; a determination section which determines a position when a colorimetry section is caused to perform colorimetry on the predetermined image printed on the print medium on the basis of the designation; a conveyance section which conveys the print medium for which printing has been completed on the basis of the position thus determined; and a colorimetric control section which acquires a colorimetry value of the colorimetry position of the designation by causing the colorimetry section to execute colorimetry on the basis of the position thus determined.

Printing colorimetric instruction method and printer

A print and colorimetry control device includes a print control section which controls so that an image for which colorimetry is to be carried out is printed on a printing medium, based on predetermined image data, a determining section which determines a position where a colorimetry section is caused to carry out colorimetry for the image based on a printing position of the image on the printing medium, a feeding section which feeds the printing medium having finished printing, based on the determined position, a colorimetry control section which controls the colorimetry section based on the determined position so that the colorimetry section is caused to carry out colorimetry thereby to obtain a calorimetric value of the image.

A calibration precision evaluating apparatus includes a calibrator carrying out calibration to adjust an ink amount output characteristic so that a measured color value is approximated to a reference value, a confirmation patch maker printing plural confirmation patches including a background patch and having the known reference values corresponding to the confirmation patches, a color measurer color-measuring the confirmation patches, acquiring initial color measured values, a background color shift amount calculator calculating a first amount of background color shift between the reference values and the initial color measured values with respect to the background patches, a corrector correcting the initial color measured values based on the background color shift amounts, acquiring corrected color measured values, and a precision evaluator carrying out precision evaluation of the calibration based on a second amount of color shift between the corrected color measured values and the reference values with respect to the confirmation patches.

Evaluation of calibration precision

An image output controller is capable of directly or indirectly controlling a printer printing a color chart and a color measuring apparatus carrying out color measurement for the color chart. When color authentication is executed for an optionally set image, a process is carried out in relation to user's setting or automatic optimization including at least one of a printing position of the color chart, a layout of the color chart and a color value of the color chart. The printer is controlled according to a printing condition based on the user's setting or the automatic optimization so that the color chart is printed on a sheet of predetermined printing paper. The color measuring apparatus is controlled so as to carry out color measurement for the printed color chart.

Before transmitting print data, a print controller transmits to a printer information on a thickness of a printing medium corresponding to a sort of printing medium which is selected on a select screen by an operator in a state that the medium thickness information is contained in control data for the print data. In the printer, a timing correction section corrects a timing of ejecting an ink drop onto a printing medium in the forward and reverse scans executed by the recording head in accordance with the control data containing the medium thickness information. Accordingly, stress imposed on the operator when the printer prints on various types of printing media in a bi-directional printing mode can be reduced.
