摘要： A specific image is first recorded according to a plurality of dot recording schemes which have an identical resolution and which are different at least in sub-scan feed operations. Then a desired dot recording scheme is selected corresponding to a desired recorded image which has been selected out of a plurality of recorded images recorded according to the plurality of dot recording schemes, and scheme selection information for specifying the desired dot recording scheme is stored into a rewritable non-volatile memory. In actual image recording, the scheme selection information stored in the non-volatile memory is read out, and a desired image is recorded on a recording medium according to the desired dot recording scheme specified by the scheme selection information.

摘要： The structure of the present invention effectively prevents banding and enables high-quality printing in a printer which carries out secondary scans in the interlacing manner and thereby prints an image. The printer of the present invention has a print head with a plurality of nozzle arrays formed thereon. Each nozzle array includes a plurality of nozzles arranged at predetermined pitches in the secondary scanning direction. The printer records an image by the interlacing method using part of the nozzles in each nozzle array. The nozzle block in the nozzle array used for formation of dots is changed in every primary scan, and the amount of feed in secondary scan is varied with the change of the nozzle block. Both the nozzle block and the amount of secondary scan are periodically changed in preset sequences. The variation in amount of secondary scan reduces the banding due to the accumulated errors in secondary scans.

摘要： A printing apparatus which avoids the occurrence of banding due to errors of sheet feeding. The apparatus includes a print head with a nozzle array including a plurality of nozzles, a main scan driving unit, a print head driving unit that drives nozzles selected from the array, a sub-scan driving unit that drives the print medium in the sub-scanning direction and a control unit. The control unit controls the main scan driving unit, the sub-scan driving unit and the print head driving unit and also carries out printing on the print medium with the print head. The control procedure of the control unit causes each of the nozzles which are not used in the process of constant pitch sub-scan printing or overlap printing, to create a dot adjoining two dots, where banding is often observed.

摘要： The pitch k of dot-forming elements is set at a product m·n of two integers m and n (where m an n are integers of no less than 2). The sub-scan feed is executed by plural sub-scan feed sets, each consisting of m sub-scan feeds. When feed amounts of the m sub-scan feeds in each sub-scan feed set are expressed as Li dots (where i is an integer of 1 to m), the following (1) and (2) hold: (1) the feed amounts Li (i=1 to (m−1)) at first through (m−1)-th sub-scan feeds are established so that a remainder obtained by dividing each feed amount Li by the pitch k is equal to the integer n; (2) a feed amount Lm in the m-th sub-scan is established so that a remainder obtained by dividing the feed amount Lm by the pitch k is an integer that is different from a value n·j that is j times the integer n (where j denotes an arbitrary integer).

摘要： The present invention utilizes a high-density ink and a low-density ink with respect to a specific color ink, so as to improve the printing quality. The procedure of the present invention reads a recording ratio of deep dots by the high-density ink corresponding to input tone data from a table and determines whether or not deep dots by the high-density ink are to be formed in a target pixel. In case that deep dots are to be formed, a piezoelectric element PE on a head of the high-density ink is driven to form deep dots. In case that deep dots are not to be formed, on the other hand, the procedure determines whether or not light dots by the low-density ink are to be formed in the target pixel by referring to the table, and specifies the on/off state of the light dots in order to cause a mean recording ratio of the light dots to be equal to a predetermined value. In the table, formation of deep dots starts in the range of tone data smaller than the specific value of tone data that gives a maximum recording ratio of light dots resulting in smooth color mixture at a joint between the record with light dots and the record with deep dots. The recording ratio of light dots may be varied according to the density of another color ink at a position corresponding to the target pixel as well as the density of the target color ink.

摘要： A printing system of the present invention reduces a total amount of discharge of at least three different color inks that are mixable to express hues in a predetermined range without deteriorating the degree of granularity. The printing system of the invention reads recording ratios of the respective color inks corresponding to input tone data regarding the respective color inks from tables TC, TM, and TY and forms dots according to the recording ratios. Yellow ink Y has a higher dye density than a balancing density that ensures a color balance. This makes the recording ratio of the yellow ink Y lower than the recording ratios of cyan ink C and magenta ink M. The yellow ink Y has high lightness, so that sparely formed dots do not increase the degree of granularity even in an area of low tone data. The enhanced density of the yellow ink Y reduces the total amount of inks discharged from a head to satisfy a required printing density.

摘要： The present invention prevents deterioration of the quality in interlace printing. The printing system of the present invention uses a head that regulates the amount of ink spouting from nozzles and forms dots of different diameters. While the diameter of dots formed in one primary scan is restricted to a fixed value, the system of the present invention enables dots of different diameters to coexist at an appropriate ratio, thereby improving the printing quality. The printing system of the present invention shifts a nozzle array, in which nozzles are arranged at intervals of a predetermined dot pitch, by a predetermined amount in the secondary scanning direction and varies the dot diameter on every primary scan, while controlling the nozzles in an overlapping state. This enables the dots of different diameters to coexist in a specified area. One preferable application carries out halftone processing under the conditions for dots of a certain diameter at the position where a dot of the certain diameter is formed. This application controls the ratio of dot formation to a desired level. For example, the probability of formation of small-diametral dots is increased in a low-density area. Another preferable application divides the nozzle array on a print head into two groups of nozzles, wherein each group of nozzles forms dots of a specified size. Appropriate selection of the nozzle pitch and the quantity of secondary scanning feed enables printing in which large-diametral dots and small-diametral dots coexist according to a predetermined rule.
摘要翻译：本发明防止隔行打印中的质量下降。本发明的打印系统使用调节从喷嘴喷出的墨水量的头部，并形成不同直径的点。虽然在一次主扫描中形成的点的直径被限制为固定值，但是本发明的系统使得不同直径的点以适当的比例共存，从而提高了打印质量。本发明的打印系统使喷嘴阵列以预定点间距的间隔排列在副扫描方向上预定量，并且在每次主扫描时改变点直径，同时将喷嘴控制在重叠状态。这使得不同直径的点在特定区域中共存。一个优选的应用是在形成一定直径的点的某一直径的点的条件下进行半色调处理。该应用程序控制点形成与期望水平的比率。例如，在低密度区域中形成小直径点的概率增加。另一个优选的应用将打印头上的喷嘴阵列分成两组喷嘴，其中每组喷嘴形成指定大小的点。喷嘴间距和二次扫描进给量的适当选择使得可以根据预定规则共存大直径点和小直径点的打印。
