An object is to provide a technique of calculating an ejection amount of an ink in accordance with a printing head. A printing apparatus includes: a printing head including an ejection port array in which multiple ejection ports to eject an ink are arrayed; a conveyer unit configured to convey a printing medium in a conveyance direction; and a controller unit configured to control the printing head. The controller unit executes processing to obtain the printing dot number based on printing data and processing to calculate an amount of the ink used in a case of performing printing based on the printing data by using different calculation methods between a case where a first printing mode is set and a case where a second printing mode is set based on the printing dot number and an ejection amount conversion factor corresponding to a temperature of the printing head.

A method for manufacturing a container according to the disclosure is a method for manufacturing a container made of metal, including a bottom portion and a body portion, open on the upper face side, and having a shape in which the body portion expands outward toward the upper face side. The method includes a bottom drawing step of reducing a diameter of a cup body made of metal and having a bottomed cylindrical shape by operating a diameter reducing die having a hole portion with a smaller diameter than an outer diameter of the cup body along a cylindrical axis direction from a bottom side, in which the bottom drawing step is repeated a plurality of times.

Method for manufacturing container and apparatus for manufacturing container

A recording apparatus includes recording elements to eject ink, heating elements to heat the ink, and a common wiring through which the recording elements and the heating elements are applied with a voltage. The recording apparatus determines a drive pulse applied to the recording elements based on the number of recording elements to be simultaneously driven and the number of heating elements to be simultaneously driven.

Recording apparatus and control method

An embodiment of the present invention provides an ink jet printing apparatus including: a print head including a printing element array provided with printing elements each configured to generate thermal energy required to eject an ink, a supply flow channel provided along the printing element array and configured to supply the ink to the respective printing elements, an opening provided to the supply flow channel and configured to cause the ink to flow in, and heating units provided along the supply flow channel and configured to heat the ink inside the supply flow channel; and a heating control unit configured to carry out heating control of the heating units based on a heating pattern determined based on heating intensity distribution, the heating intensity distribution representing heating intensities corresponding to the respective heating units and representing the heating intensities corresponding to positions in a direction of the printing element array.

Ink jet printing apparatus, control method, and storage medium

An inkjet printing apparatus includes a print head configured to print an image on a printing medium using a printing element configured to eject ink with thermal energy, a scanning unit configured to cause the print head to scan the printing medium, and a control unit configured to control scanning by the scanning unit and image printing by the print head based on an image printing instruction, wherein the control unit performs a control operation including executing a preliminary ejection to eject, from the print head, ink that does not contribute to image printing before an image is printed in one scanning operation, and determining an amount of ink to be ejected in the preliminary ejection based on a difference between a target temperature and a scanning start temperature, which is a temperature of the print head acquired in response to an instruction to start the one scanning operation.

Inkjet printing apparatus, control method therefor, and storage medium

A printing apparatus prints by discharging ink to a transfer member from a first printhead, discharging a transfer accelerator to the ink from a second printhead, and transferring an image formed on the transfer member to a print medium. When inspecting a discharge state of each of plural nozzles provided in each of the first and second printheads, the apparatus controls the second printhead so as to discharge the transfer accelerator from at least one nozzle of the second printhead to a discharge area of the transfer member to which the ink is discharged by the first printhead for inspection of the discharge states of the plural nozzles of the first printhead, while inspecting a discharge state of a nozzle different from the at least one nozzle of the second printhead by discharging the transfer accelerator from the nozzle.

Printing apparatus and inspection method therefor

A printing apparatus includes a printing unit configured to print an image on a print medium, an acquiring unit configured to acquire temperature information of the printing unit, and a control unit configured to control the printing unit so as to start relative scanning in a case where a temperature that is indicated by the temperature information has reached a print permission temperature. The print permission temperature in a first print mode whose speed at a time of a constant speed in relative scanning is a first speed is a first temperature. The print permission temperature in a second print mode whose speed at the time of the constant speed is a second speed that is faster than the first speed is a second temperature that is lower than the first temperature.

Printing apparatus, control method, and storage medium

An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Inkjet printing apparatus and inkjet printing method

A printing apparatus for printing using a printhead including a plurality of nozzles, each configured to discharge ink, and a plurality of sensors, corresponding to the plurality of nozzles, for detecting a discharge state of ink from the plurality of nozzles, judges a discharge state. The apparatus prints, based on print data, an image by driving the printhead under a first drive condition to discharge the ink from the printhead to a first area, discharges ink to a second area different from the first area by driving the printhead, based on inspection data, under a second drive condition different from the first drive condition, and judges a discharge state of each nozzle by monitoring an output from each sensor at a timing of driving the printhead under the second drive condition.

A method for manufacturing a metal bottle having a mouthpiece in an upper part of a bottomed cylindrical bottle body, including forming a screw part on the mouthpiece and then forming a curl at a tip of the mouthpiece. During formation of the screw part, a height of the first-stage screw thread from a tip side in a complete screw part and a height of the second-stage screw thread from the tip side are substantially equal and a distance between an apex part of the first-stage screw thread and a bottle axis is smaller than a distance between the apex part of the second-stage screw thread and the bottle axis. After formation of the curl, a distance between the apex part of the first-stage screw thread and the bottle axis and a distance between the apex part of the second-stage screw thread and the bottle axis are substantially equal.

A bottle can has a curl part at an opening end of a mouth part thereof. The curl part has an upper end curved part in which an upper part of a neck shoulder part of the mouth part is curved outward and an outer wall part extending downward from the upper end curved part. A predetermined angle at which an outer edge side of a lower end face of the outer wall part opens is formed between the lower end face of the outer wall part and the neck shoulder part. An inner edge of the lower end face comes into contact with the neck shoulder part when a downward load is applied to the curl part from above.
