摘要： The present invention provides an ink jet printing apparatus and a method for controlling temperature for the ink jet printing apparatus wherein the temperature of a print head, which may lower during printing, is controlled before printing without using any sub-heater to allow a favorable ejection condition to be established without reducing the head temperature below a predetermined value. Thus, scan width information and dot count information are acquired before a carriage starts scanning to determine the heating temperature of the print head on the basis of the information.

摘要： A method of adjusting bidirectional registration to reduce negative effects on the image such as “banding” even if bidirectional registration includes a slight amount of displacement is provided. For that purpose, correction is applied to a first adjustment value for adjusting a bidirectional registration displacement in response to an extent of inclination of a printing head to obtain a second adjustment value. Then a bidirectional printing is performed with timing adjusted on the basis of the second adjustment value. As a result of that, even if there is a slight variation in an adjustment value of the bidirectional registration and the inclination of the printing head, the banding generated by this can be reduced as much as possible.

摘要： In an image printing apparatus for printing an image by combining dots of a plurality of sizes, a banding problem attributable to variations in conveying operation, and a temperature rise of a print head with an increase of the number of ejections are solved with a relatively simple configuration. To this end, a combination of dots of a plurality of sizes is assigned to each of pixels expressed at a plurality level of density. In this assignment, a dot larger than a pitch of an image resolution is preferentially allocated to a pixel having a density level higher than that to which one dot smaller than the pitch of the image resolution is allocated.

摘要： In an image processing method, on the basis of input image data with respect to a target pixel, independent multi-level data (g0, g1) corresponding to respective plural species of dots which are different in at least one of a density and a diameter are generated, and then data (O0, O1) relating to an amount of generation of the dots with respect to the target pixel are generated on the basis of a relationship between the generated independent multi-level data (g0, g1) corresponding to the plural species of dots. The image processing method is effective in performing design having a high degree of flexibility in proper use of a relatively high power dot (high density dot or large dot) and a relatively low power dot (low density dot or small dot) and can realize obviation or alleviation of an occurrence of granulation or an apparent frame caused due to the relatively high power dot.

摘要： In the case where a multipass printing and an interlace printing are used together, the present invention enables outputting an image of good quality independently of the relation between the number of passes in the multipass printing and increase in the resolution in the sub-scanning direction through the interlace printing. Data processing is executed while pixels of inputted image data are made to correspond to two or more rasters in the sub-scanning direction, so that the dots are arranged in these rasters at a substantially equal rate, in the case where the number of print scannings to be executed multiple times is not an integral multiple of the number of rasters.

摘要： When a printing position is displaced by an inclination of a printing head, for example, the displacement can be corrected in an easy and effective manner and a user can easily recognize the displacement of the printing position to correct the displacement. To realize this, dots for forming a test pattern are formed by different scannings by a nozzle group including a plurality of nozzles positioned at one end side of a nozzle row and a nozzle group including a plurality of nozzles positioned at the other end side of the nozzle row. Depending on displacements of the printing positions of these dots, the plurality of nozzles constituting the nozzle row are divided into a plurality of divided nozzle groups. Then, the printing position is adjusted on the basis of the divided nozzle groups.
