Abstract: A printing apparatus includes a head and a drive signal generating section. The head has an element performing operation for ejecting ink and ejects a plurality of types of inks, an amount of each ink ejected by the head being different depending on a designated tone value. The drive signal generating section generates a drive signal having a waveform section for operating the element and generates a plurality of types of the drive signals for a specific tone value, the waveform section of each of the drive signals for the specific tone value being different depending on the types of inks.

Abstract: A printing method includes performing a first printing process that alternately repeats a first carrying operation and a dot forming operation and performing a second printing process that alternately repeats a second carrying operation and the dot forming operation when printing an image at an edge portion of a medium upstream in a carrying direction. The first carrying operation is an operation that carries the medium by a first carrying amount in the carrying direction, and the dot forming operation is an operation that forms a dot line on the medium by ejecting ink from a plurality of nozzles aligned in the carrying direction, a plurality of the nozzles includes a nozzle opposed to a convex portion, of a supporting member, that is in contact with the carried medium and a nozzle opposed to a concave portion, of the supporting member, that is not in contact with the carried medium.

Abstract: A liquid ejecting apparatus includes: a head having a nozzle; a pressure-changing unit for changing pressure of liquid in the nozzle in such a manner that the liquid is ejected from the nozzle; a first level-data setting unit for setting a selected first level data from a plurality of first level data, based on an ejecting data for a first kind of liquid; a second level-data setting unit for setting a selected second level data from a plurality of second level data, based on an ejecting data for a second kind of liquid; a driving-signal generator for generating a driving signal; and a driving-pulse generator for generating a driving pulse based on the selected first or second level data and the driving signal. The plurality of first level data and the plurality of second level data are different from each other.

Abstract: The invention relates to a printing method that repeats in alternation a carrying operation of carrying a medium in a carrying direction, and a formation operation of forming an image on the medium by ejecting ink from a plurality of nozzles that are aligned in the carrying direction and that move in a movement direction.

Abstract: A method for adjustment of a printing apparatus, includes the steps of: (i) receiving an instruction from a user via a user interface; (ii) forming a plurality of patterns on a medium using an ink ejecting section that ejects ink onto the medium, each of the patterns being a pattern for adjusting a different object; (iii) detecting each of the patterns with a sensor; and (iv) adjusting each of the plurality of objects based on a result of detecting each of the patterns. With this adjustment method, if the image quality of the printed image has dropped, even a user who is not well versed in an inkjet printer's functionality can achieve an appropriate image quality improvement.

Abstract: Darkness correction is carried out effectively. A printing method is provided with the following steps: A step of, when a plurality of nozzles arranged in a predetermined direction for each of a plurality of colors of ink is moved in a movement direction intersecting with the predetermined direction while ejecting ink of the plurality of different colors, correcting a darkness of only a predetermined color, of the plurality of colors, for each dot row region so as to inhibit darkness non-uniformities between dot row regions that are formed on a medium by dot rows in the movement direction of the nozzles, and a step of performing printing by moving the plurality of nozzles while ejecting ink.

Abstract: A method for ejecting liquid comprises the steps of: forming an adjustment pattern in a predetermined position on a medium by ejecting liquid onto the medium; determining whether or not to form the adjustment pattern again; and if it is determined that the adjustment pattern is to be formed again, then forming the adjustment pattern again in a position that differs from the predetermined position by ejecting liquid onto the medium.
