An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.

An adjustment method of a printing apparatus capable of properly drying a medium is provided. An adjustment method of a printing apparatus is provided and the adjustment method includes printing on a medium a plurality of patches having different amounts of liquid discharged from a printing unit, and adjusting a heating temperature of a drying unit configured to heat the medium by referring to correspondence data indicating a correspondence relationship between the heating temperature of the drying unit and an amount of evaporation of the liquid caused by the drying unit, based on a dry condition of the patch that have been subjected to drying by the drying unit.

A printer having a printhead configured to print to a print medium; a camera configured to photograph the print medium; a carriage configured to support and move the printhead and the camera; and a processor configured to print, by the printhead, on the print medium a first test pattern that is larger than an imaging area of the camera, photograph the first test pattern by the camera, and detect a printing defect based on a result of the photograph.

An image processing apparatus that generates data for setting different colors for a projected portion and a recessed portion of an unevenness on a surface of a recording medium by recording a colored printing material on at least the projected portion of the unevenness includes a first acquisition unit configured to acquire recording amount data representing a recording amount of the colored printing material, and a halftoning unit configured to perform first halftoning on the recording amount data to arrange a larger number of dots of the colored printing material to be recorded on the projected portion of the unevenness at a center of the projected portion than at edges of the projected portion.

A printing apparatus includes a printer with printing elements that print dots and a controller that acquires input image data. The controller acquires a pre-correction printing density that is based on test pattern data, which includes a uniform array of pixels, and printing characteristics of printing positions of the dots printed by the plurality of printing elements. The controller calculates a target density by averaging the pre-correction printing density and offsets the target density so that the target density is equal to or greater than the pre-correction printing density. The controller calculates a correction gain of the plurality of printing elements on the basis of the ratio of the target density to the pre-correction printing density and controls the printer on the basis of the correction gain and the input image data.

A recording apparatus includes a head and a controller. The controller discriminates first and second regions on a recording medium based on received image data, sets a boundary region that includes a boundary of the first and second regions, sets a first discharge speed for a discharge speed of droplets from the head to be landed to a first main region included in the first region, sets a second discharge speed slower than the first discharge speed for a discharge speed of droplets from the head to be landed to a second main region included in the second region, and sets a discharge speed between the first discharge speed and the second discharge speed for a discharge speed of droplets form the head to be landed to the boundary region.

White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

An image recording device and an image recording method capable of matching landing positions between droplet types in a consecutive ejection drive method are provided. The object is resolved by an image recording device in which a drive waveform for forming a dot of a small droplet is a drive waveform for ejecting a liquid droplet by a first ejection waveform element arranged in a first half of one drive cycle, and a drive waveform for forming a dot of a medium droplet is a drive waveform for ejecting the liquid droplet by the first ejection waveform element and a second ejection waveform element arranged after the first ejection waveform element in time series, and the liquid droplet ejected by the first ejection waveform element and the liquid droplet ejected by the second ejection waveform element are not combined while reaching onto a recording medium.

A supporting member includes a first supporting portion disposed on a first and second recording element substrate side, and a second supporting portion disposed on a side opposite to the first and second recording element substrate side with respect to the first supporting portion, the first supporting portion includes a first individual flow path for supplying liquid to a first recording element substrate, and a second individual flow path for supplying liquid to a second recording element substrate, and the second supporting portion includes a common flow path for supplying liquid to the first and second individual flow paths.
