To print high-definition images, an embodiment of the present invention provides a printing apparatus including: a printing unit configured to print an image on a printing medium by applying a first liquid containing a colorant and a second liquid containing a component that causes the colorant to aggregate; a control unit configured to control the printing unit so as to print a first pattern and a second pattern differing from the first pattern in a manner of application of the first liquid and the second liquid; and an identification unit configured to identify a characteristic of the printing medium based on a first density of the first pattern and a second density of the second pattern.

Printing apparatus and identification method

A recording apparatus that causes less degradation of image quality due to blurring caused by dot misalignment between an ink containing a coloring material and a reaction liquid includes a recording unit configured to record an image on a recording medium by applying an ink containing a coloring material and a reaction liquid containing a component that aggregates the coloring material, an acquisition unit configured to acquire multi-valued ink data to apply the ink, and a generating unit configured to generate first multi-valued reaction liquid data based on the multi-valued ink data and, when a tone value of a pixel of interest in the first multi-valued reaction liquid data is lower than a tone value of any one of a plurality of surrounding pixels around the pixel of interest, generate second multi-valued reaction liquid data by increasing the tone value of the pixel of interest.

Recording apparatus, method, and medium

An information processing apparatus, an information processing method, and a storage medium that execute density characteristics acquisition processing at an appropriate timing are provided.

Information processing apparatus, information processing method, and storage medium

A printing apparatus performs control so that out of N scans for printing an image in a predetermined region on a print medium, a total application amount of a reactive liquid printed by first N/2 scans and a total application amount of the reactive liquid printed by second N/2 scans may be different between a case where an application amount of the reactive liquid per unit area which corresponds to the predetermined region is a first amount and a case where the application amount of the reactive liquid per unit area is a second amount larger than the first amount.

Printing apparatus and printing method

An image printing apparatus and a method of controlling the same are capable of appropriately correcting the conveyance amount in each of a plurality of conveyance paths. In a case of conveying a print medium along a first conveyance path, a controller controls the driving of a conveyance motor based on first information. In a case of conveying the print medium along a second conveyance path, the controller controls the driving of the conveyance motor based on second information, which is different from the first information.

Image printing apparatus and control method

A printing control apparatus includes a control unit configured to perform control so that a distribution ratio based on which color separation data separated as having a predetermined color is distributed into data for a first nozzle array and a distribution ratio based on which color separation data is distributed into data for a second nozzle array are different depending on a tone value in the color separation data, and a generation unit configured to generate printing data to be used for printing by the first nozzle array based on the distributed data for the first nozzle array and generate printing data to be used for printing by the second nozzle array based on the distributed data for the second nozzle array.

Printing control apparatus and printing control method

An object is to provide a full-line inkjet printing apparatus and a printing method that can suppress occurrence of image degradation in the case where a conveyance roller conveys a print medium and multipass printing is performed. The maximum conveyance amount in a return route is set to be smaller than a distance between the conveyance roller and a print head.

The object of the present disclosure is to optimize the time necessary for filling and the ink consumption. One embodiment of the present disclosure is a printing apparatus having: a storage unit; a print head having an ejection port from which ink supplied from the storage unit is ejected; an ink supply path that connects the storage unit and the print head; a suction unit configured to perform suction at the ejection port; and a supply control unit configured to supply ink stored in the storage unit to the ink supply path and the print head by performing suction at the ejection port by the suction unit, and the printing apparatus has an acquisition unit configured to acquire information relating to ink discharge from the ink supply path and the supply control unit determines the number of times of suction by the suction unit based on the information.

Printing apparatus, control method thereof and storage medium

Information processing apparatus, information processing method, and storage medium that determine execution of density characteristics acquisition processing at an appropriate timing

Provided is an inkjet printing apparatus that can reduce smears on a back surface of a print result medium by reducing accumulation of ink in a platen while reducing generation of mist. To achieve this, an ink receiving portion of a platen is provided away from a support surface by a predetermined distance, is formed in a mesh shape by laying multiple linear members, and is formed as a guide member that guides the ink received in the ink receiving portion to an ink guide holes.

Inkjet printing apparatus

A printing apparatus includes an ink tank that stores ink, a supply tube that supplies the ink from the ink tank, and a printing head that includes therein a pressure chamber arranged with an ejection port to eject the ink and performs reciprocal moving. The printing head includes a first liquid chamber that includes a connection portion with the supply channel, a second liquid chamber that communicates with the first liquid chamber by way of the pressure chamber, and a volume variable unit that changes an inner volume of the second liquid chamber.

Printing apparatus

A recording apparatus discharges an ink in a first color to a position at which an accumulated state on an ink absorber is to be detected. After that, a light is emitted onto the position from a light emitting unit, and reflected light is received by a light receiving unit.

Recording apparatus and method in recording apparatus

According to an embodiment of this invention, an apparatus comprises: a detachable inktank containing ink; a subtank containing the ink supplied from the inktank; a printhead configured to discharge the ink supplied from the subtank; an ink supply path connecting the subtank to the printhead; a valve arranged on the ink supply path; a supply unit configured to supply the ink from the inktank to the subtank by repeatedly opening and closing the valve; a suction unit configured to suck the ink from the printhead; and a control unit configured to control, when the inktank is attached, the supply unit to operate for a predetermined number of times to supply the ink from the inktank to the subtank, and to subsequently control the suction unit to operate to supply the ink from the subtank to the printhead.

Inkjet printing apparatus and ink filling method

Images with high image quality having less time-difference unevenness are outputted in an inkjet printing apparatus that performs multi-pass printing using full-line inkjet print heads. For this purpose, a CPU is capable of setting a first printing method in which an image for a unit area is printed by a specified number of printing conveyance operations and a second printing method in which an image for a unit area is printed by a smaller number than the specified number of printing conveyance operations. The CPU sets conveyance conditions such that a taken time for one printing conveyance operation of the printing conveyance operations for a unit area in the second printing method is smaller than a taken time for one successive printing conveyance operation of the printing conveyance operations for a unit area in the first printing method.
