In a recording apparatus, a dot diameter of a first color ink formed by discharging a predetermined amount of the first color ink onto a surface of a second color ink fixed on a recording medium is smaller than a dot diameter of the second color ink formed by discharging the predetermined amount of the second color ink onto a surface of the first color ink fixed on the recording medium, and a recording head discharges the plurality of inks such that with respect to pixels forming an image in a unit area, pixels formed by discharging the second color ink and the first color ink in this order are greater than pixels formed by discharging the first color ink and the second color ink in this order.

Recording apparatus and recording method for improving the clarity of an image

A recording method includes applying and overcoating. A color ink is applied to a region on a medium. A clear ink is applied to the region. The applied color ink and the applied clear ink are overcoated.

Ink jet recording apparatus and ink jet recording method

In a case where ink having a relatively high dot height is ejected a small amount, binary data corresponding to ink having a relatively low dot height is quantized so that dot adjacency is increased.

Image processing apparatus, image processing method, and image recording apparatus

When recording is performed using two different types of inks, the ink discharge order is controlled in a unit region on a recording medium so that the number of pixel regions in which an ink having a relatively high pH buffer capacity in a basic region is applied later is larger than the number of pixel regions in which an ink having a relatively low pH buffer capacity in a basic region is applied later.

Image recording apparatus, image recording method, image processing apparatus, and storage medium

An inkjet printing device having a print head that ejects a plurality of types of inks has: an ejection unit configured to, on the basis of ejection data that scans the print head a plurality of times to eject the inks from the print head to a predetermined area of a print medium, eject the inks to print an image; wherein the inks are classified into a first ink having a relatively large contact angle and a second ink having a relatively small contact angle, and wherein the ejection data is ejection data that, if a difference in application amount between the first ink and the second ink to be ejected to the predetermined area by the ejection unit is larger than a predetermined value, increases a ratio at which an ink having a smaller application amount is ejected in last half scans among the plurality of times of scans.
