摘要:
Gradation data for each color to be input to a recording apparatus includes dot-recording-position information for every unit pixel and information for determining a nozzle position in a recording head for recording a dot. The information for determining the nozzle position makes determination in accordance with image data of an ink with resin and image data of an ink without resin. In a region where the ink with resin and the ink without resin overlap with each other, the ink without resin can land first.

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.

In an inkjet printing apparatus, degraded image quality due to ink viscosity increasing is suppressed without forming ink dots unrelated to the print image as in what is called on-sheet preliminary ejection. More specifically, print data is generated for each pass in a multi-pass printing, such that the ratio of dots continuously formed by the same nozzle during the same scan becomes greater in low-duty areas than in high-duty areas. Thus, the lengthening of nozzle nonuse time can be suppressed, even in the case of printing a low-duty area. As a result, it becomes possible to suppress degraded image quality due to ink viscosity increasing.

A coating liquid for use in an ink jet recording method comprising an image forming step of forming an image on a recording medium by an ink jet system with an ink comprising at least a pigment and a coating layer forming step of applying a coating liquid at least to a region including the image to form a coating layer having a film thickness of from 0.10 μm or more to 1.0 μm or less in at least a part thereof. The coating liquid comprises at least a slippery compound, water and a water-soluble organic solvent. The coating layer has a coefficient of kinetic friction of 0.40 or less.

In an ink jet printing apparatus carrying out printing using a plurality of ejecting portions for respectively ejecting different kinds of inks, a condition for wiping of an ejection face provided with ink ejection openings of the plurality of ejecting portions is appropriately determined and defective ejection due to a wet and dirty ejection face is effectively prevented. A timing of wiping is controlled considering kinds of inks. Specifically, the timing of wiping is determined not simply based on a number of ejections carried out by the plurality of ejecting portions to perform printing, but also a condition of an amount of mist generated in accordance with the kinds of ink.
摘要:
An ink jet printing apparatus, an ink jet printing method, and a data generating apparatus are provided in which an image performance such as an abrasion resistance can be improved and a printing head can have a longer life by ejecting processing liquid at an appropriate time. The processing liquid is ejected, to a predetermined area on a printing medium in which the formation of a image by ink is completed, from a printing head in two or more scannings in five scannings of the printing heads.
摘要:
A color ink jet recording method/apparatus is capable of reducing blurring of ink dots without reducing dot saturation, generating no difference in tones of secondary colors, and inviting no reduction of throughput, hence materializing an excellent performance of recording in high quality at high speed. A color image is formed by causing ink dots of plural colors to land in such a manner that each of the ink dots is essentially not superposed. The ink dots have the optical density of 1 or more and 1.5 or less. Thereby, overlapping between adjacent ink dots is lessened, and thus a high-quality color image having no difference in tones of secondary colors and a high saturation can be attained.

An inkjet printing apparatus includes a print head that scans a same area of a printing medium plural times and ejects plural kinds of ink and a treatment liquid thereon to form an image, and an ejection data generating unit for generating ejection data for ejecting the plural kinds of ink and the treatment liquid to each predetermined area of the printing medium in a predetermined order from the print head. The plural kinds of ink are classified in plurality based upon a minimum application amount of the treatment liquid per a predetermined area required for realizing an effect of the treatment liquid, and the ejection data generating unit generates the ejection data in such a manner as to eject the plural kinds of ink and the treatment liquid from the print head according to the order determined in accordance with the classification of the ink ejected within the predetermined area.
