摘要： The ink jet printing apparatus of this invention is intended to reduce degradations in image quality caused by color mixing due to bleeding of inks of different colors and thereby enable printing an image with high quality at high speed. To this end, in the ink jet printing apparatus of this invention, a plurality of different nozzle groups are main-scanned M times (M≧2) over a print area to print all print data to be printed on the print area to complete an image. The print head, successively perform the main scans over the print area in such a way that the print head, located at the front position in the printing order, performs an Mth main scan with a lower print density than that of an Nth main scan (1≦N

摘要： A recording apparatus is provided with two or more kinds of sub-scanning amounts per main scan, and records a high quality image by reducing the bleeding between colors created characteristically by a multi-pass recording method. The number of times of main scanning to complete an image by a first discharge port array for black ink use and a second discharge port array for color ink use, respectively, are set to be m (m is a positive integer) and n (n is a positive integer) times. With respect to discharge ports to be used for recording in the first and second discharge port arrays, a distance between discharge ports which are positioned at upstream ends of the respective first and second discharge port arrays in the sub-scan direction is made equal to a length of a continuously conveying amount of (m+a) (a is a positive integer) times by combination of the at least two kinds of conveying amounts.

摘要： To achieve high-quality printing by controlling an ink-traveling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink ejected to areas outside edges of the printing medium is prevented from being attracted to the end portions in margin-less printing. This configuration includes: a platen, made of a conductive material, positioned immediately below the printing medium; an absorber positioned at a side of the edge; and a mesh conductive member disposed on the absorber. A first voltage is applied to the platen, causing polarization in the printing medium, and a second voltage higher than the first voltage is applied to the conductive member. Thereby, ink ejected outside the edges in the margin-less printing, travels straight-forwardly toward the conductive member without being attracted to the end portions, and is absorbed into the absorber via the conductive member.

摘要： A printing apparatus performs printing by scanning a printhead having an array of printing elements in which a plurality of printing elements are arranged in a predetermined direction, over a printing medium according to control information and image data transmitted from a host apparatus. Setting information designating some of the printing elements to be used for printing in the printing elements in the printhead according to a predetermined printing parameter is transmitted as control information from the host apparatus to the printing apparatus in the printing apparatus, the printing elements to be used are set according to the setting information. Data to be printed by the printing elements used for printing in correspondence with scanning is generated in the host apparatus and transmitted as image data from the host. The printing apparatus performs printing by driving the set printing elements according to the image data during scanning. Control relating settings of printing parameters in the printing apparatus is thus simplified to effectively reduce the capacity of a memory and the number of gates of a logic circuit provided in the printing apparatus. The manufacturing cost and the size of the printing apparatus are thereby reduced.

摘要： A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.

摘要： In an inkjet printing apparatus utilizing an inkjet head and an ink tank for supplying ink to the same, it is made possible to suppress any reduction in image quality attributable to changes in physical and chemical properties of the ink that occur during an elapsed time from the manufacture of the ink tank to the use of the same, thereby allowing images to be formed with high reliability and stability at a low running cost. The apparatus has a discharging unit for discharging the ink through a nozzle at the head and an ink detecting unit for detecting the consumption of the ink in the ink tank. The detected ink consumption is compared with a threshold for ink consumption appropriately determined based on the elapsed time, and control is performed such that the amount discharged by the discharging unit is increased when the ink has not been consumed sufficiently.
