Description of the invention (2) Fill the faulty nozzle 4 6 4 with other nozzles. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for printing a color image by an inkjet printer to solve the above problems. The scope of patent application of the present invention is to provide a method for printing a color image using an inkjet printer. The inkjet printer includes print heads of three rows of print nozzles aligned in the same direction. The first row of nozzles emit light magenta ink. The second row of nozzles is divided into three areas, the first area ejects magenta ink, the second area ejects cyan ink, and the third area ejects yellow ink. The third row of nozzles ejected 1 i ght cyan ink. The length of the three rows of nozzles is approximately equivalent to "3 * H", where "H" represents the length of the three regions in the second row. The method includes, under the necessary operation for printing out the characteristics of the image, the nozzles in the first, second and third areas of the second line eject ink during each scan of the print head by the print head, The printing medium advances about a distance Η in the first direction, and when printing the features of the image, the print head scans the print medium three times, and the nozzles in the first row and the nozzles in the third row will eject ink. Another object of the present invention is to provide a method for ejecting ink with the nozzles in the first row or the nozzles in the third row to fill the defective nozzles in the second row. 1232177 V. Description of the invention (3) A method of filling the defective nozzle When the printhead scans the printing medium phase gate & 1 P color image features, the defective nozzle of the area and the first- Or second, the method also includes ejecting ink from the first nozzle. Ink, the first nozzle that fills the second row ejects twice the faulty nozzle that the print medium advances two or more in the-direction, and the advantage of the present invention is that the printer simultaneously masters and magenta ink to reduce the print head Scanning printing media: In addition to magenta, the printer can also use light-colored ink to fill the ejection. In addition to the defective nozzles, there is no need for an additional scan of the list head to eject the defective nozzles of dark green or dark red ink. [Embodiment] Please refer to FIG. 2. FIG. 2 is a schematic view of an ink jet list head i 0 0 according to the present invention. The print head is divided into four rows and three rows of nozzles 1,2, and the user can adjust the number of rows as desired. The two central banks of the nozzles 1 12 provide yellow, magenta, and cyan inks from the two central ink channels 104Y, 104 M, and 104 C arranged on the substrate 101 of the print head 100, respectively. The yellow ink group 1 2 2 of the nozzle 1 12, the magenta ink group 1 2 2 M, and the cyan ink group 1 2 2 c are respectively arranged in Γ :: ii Dolan, _, and-side. The print head 1 0 0 also includes a plurality of outer row nozzles 11 2. The first outer row 1232177 V. Description of the invention (4) 'The light magenta ink set 1 2 8 m including the nozzle 1 12 is one of the substrates 1 0 1 which is removed from the printing head 1 0 0 Supplied with side ink channel 108 m. The second outer row contains the light cyan ink set 1 2 6 c of the nozzle 1 12, and the ink is provided by the ink channel 1 6 c arranged on the other side of the substrate 1 0 1 of the print head 100. The light magenta ink set 1 28m of the nozzle 1 12 and the light cyan ink set 1 2 6 c will extend from the first row to the third row of the print head 100. In addition, the number of nozzles in each row of the print head 100 is the same. Please refer to Fig. 3. For the convenience of explanation, Fig. 3 shows a simplified version of the print head 100 of Fig. 2 print head 10. The print head 10 includes the nozzles i 丨 2 in the first row 20, the second row 30, and the third row 40. The first line 2 0 contains nozzles 2 of the first area 2 2, the second area 24, and the third area 26, and each area can eject light magenta ink. The second row 3 0 contains the nozzles 112 of the fourth region 3 2, a fifth region 34, and a sixth region 36, which can eject yellow, annual red, and cyan inks, respectively. The third row 40 contains the seventh, fourth, and eighth regions 42, 44 and 46 which can eject light cyan ink. Use u z 都 G 2G, f ί 3 (3 and the third row of 4G each-the mouth of the area 2 Er 2 J 2, = t the height of each area is set to Η. Although the diagram,

1232177 五、發明說明（5) 1 0掃描該列印媒介時，該列印媒介可推進約Η的長度。除此之外，既然第一行2 0以及第三行4 0之三區域之喷嘴1 1 2 分別喷出相同的墨水，所以只要列印頭1 〇每掃描過該媒介三次時列印出墨水即可。請參閱圖四，並同時參閱圖三，圖四係本發明之列印頭1 0掃描該媒介項次之時點示意圖2 0 0。欲列印在該媒介上之圖像係以箭頭A1標示上限，箭頭A 6標示下限。為解說在一般情況下的列印頭1 0之操作，所以該圖像之每一列將會以淡青、淡洋紅、青、洋紅以及黃色墨水列印。為了列印列印頭1 0之第二行3 0之三種顏色到該圖像之同一列上，所以需要列印頭1 0三次不同的掃描以及在每次掃描之間該媒介會推進距離Η。在掃描時，第一行2 0 之喷嘴1 1 2喷出淡洋紅色墨水以及第三行4 0之喷嘴1 1 2喷出淡青墨水之次數比第二行3 0之喷嘴1 1 2喷出黃色、洋紅以及青色墨水次數多出三倍。因此，在列表頭1 0掃描該媒介之期間，第二行3 0每次都要掃描都要喷出墨水，而第一行2 0以及第三行4 0僅需要每三次掃描喷一次墨水即〇在時點10時，列印頭1 0第一次掃描該媒介，並列印點狀線2 0 4到該媒介上。在第一次掃描時，僅第二行3 0會喷出墨水到媒介上。又因為只有列印頭1 0之第三區域低於箭頭A 1所指的圖像的上限，所以只有第六區域3 6之喷1232177 V. Description of the invention (5) 1 0 When the printing medium is scanned, the printing medium can advance by about Η. In addition, since the nozzles 1 1 2 in the area of the first 20 and third lines 40 3 eject the same ink respectively, as long as the print head 1 〇 prints the ink every time the medium is scanned three times Just fine. Please refer to FIG. 4 and FIG. 3 at the same time. FIG. 4 is a schematic diagram of the time at which the print head 10 scans the media item of the present invention 2 0 0. The image to be printed on the medium is indicated by the arrow A1 and the arrow A6 is the lower limit. In order to explain the operation of the print head 10 under normal circumstances, each column of the image will be printed with light cyan, light magenta, cyan, magenta, and yellow ink. In order to print the three colors of the second row and third row of print head 10 to the same column of the image, three different scans of print head 10 are needed and the medium will advance the distance between each scan. . During scanning, the nozzle 1 1 2 in the first row 20 ejected light magenta ink and the nozzle 1 1 2 in the third row 40 ejected light cyan ink more frequently than the nozzle 1 1 2 in the second row 30 Three times more yellow, magenta and cyan inks. Therefore, during the scan of the medium at the top 10 of the list, the second line 30 will eject ink each time, while the first line 20 and the third line 40 only need to eject the ink every three scans. 〇 At 10 o'clock, the print head 10 scans the medium for the first time, and prints a dotted line 204 on the medium. During the first scan, only the second line 30 will eject ink onto the media. Because only the third area of the print head 10 is lower than the upper limit of the image indicated by the arrow A 1, only the sixth area 36

第11頁 1232177 五、發明說明（6) 嘴1 1 2會在線2 0 4之箭頭A 1以及A 2間喷出青色墨水。在時點11之前，列印頭1 0已經完成第一次掃描，且推進該媒介距離Η。在時點11時，列印頭1 0作第二次掃描並列印線2 0 8以及2 1 2。在第二次的掃描中，第一行2 0以及第二行3 0之喷嘴1 1 2都會喷出墨水。因為只有後三分之二的列印頭1 0在箭頭A1之下，所以箭頭A1以及A 3之間的墨水會從第八區域4 4、第九區域4 6、第五區域3 4以及第六區域3 6之喷嘴 1 1 2喷出。在時點12之前，列印頭1 0會完成第二次掃描，且會推進距離Η。在時點12開始進行第三次掃描前，列印頭1 0已經完全在箭頭A1之下，因此列印頭1 0之全部區域皆可用來列印。在第三次的掃描中，第二行3 0以及第三行4 0之喷嘴 1 1 2都會在線2 1 6以及線2 2 0之箭頭A 1以及A4之間喷出墨水0 在時點t 3時，進行第四次掃描，第二行3 0之所有喷嘴1 1 2會在線2 2 4之箭頭A 2以及A 5之間喷出墨水。同樣地，在時點14時，進行第五次掃描，第一行2 0以及第二行3 0之所有喷嘴1 1 2會在線2 2 8以及線2 3 2之箭頭A 3以及A 6 之間噴出墨水。 1232177 五、發明說明（7) 一旦到了時點t 5的第六次掃描時，就僅有前三分之二之列印頭1 0在箭頭A 6之上，如此只會列印圖像之底部。因為第二行3 0以及第三行4 0之喷嘴1 1 2將會在第六次掃描時喷出墨水，所以只有第四區域3 2、第五區域3 4、第七區域4 2以及第八區域4 4之喷嘴1 1 2會喷出墨水。最後則進行第七次掃描，且只有前三分之一的列印頭1 0在箭頭A 6之上。因為只有第二行3 0將喷出墨水，故僅有第四區域3 2之喷嘴1 1 2會喷出墨水。有一點需要注意的是，如圖四所顯示的七次掃描中，因為第二行3 0會喷出三種不同顏色的墨水，所以第二行3 0在每次掃描時都會喷出墨水。另一方面，第一行 2 0僅在第二次以及第五次掃描時會喷出墨水，而第三行 4 0只有在第三次以及第六次掃描時會喷出墨水。因此，第一行2 0以及第三行4 0是每三次掃描喷出一次墨水，而第二行3 0是每次都會喷出。雖然圖四之例子顯示第一行 2 0以及第三行4 0在不同的掃描項次喷出墨水，但事實上，也是可以在同一次掃描中都喷出墨水的。在每次掃描中，為了要更有效率，所以列印頭1 0只要可以，不論何時都可從第一行2 0以及第三行4 0之三區域喷出墨水。當然，僅從三區域中的兩區域裡喷出墨水也是可以的。既然如此，第一行2 0以及第三行4 0在列印Page 11 1232177 V. Description of the invention (6) The nozzle 1 1 2 will eject cyan ink between the arrows A 1 and A 2 of the line 2 0 4. Before time 11, the print head 10 has completed the first scan, and the media distance 媒 is advanced. At 11 o'clock, the print head 10 performs a second scan and prints lines 2 08 and 2 1 2. In the second scan, the nozzles 1 12 in the first row 20 and the second row 30 eject ink. Because only the last two thirds of the print heads 10 are below the arrow A1, the ink between the arrows A1 and A 3 will change from the eighth area 4 4, the ninth area 4 6, the fifth area 34, and the first. The nozzles 1 1 2 of the six areas 36 eject. Before 12 o'clock, the print head 10 will complete the second scan and advance the distance Η. Before the third scan starts at 12 o'clock, the print head 10 is completely under the arrow A1, so all areas of the print head 10 can be used for printing. In the third scan, the nozzles 1 1 2 in the second row 30 and the third row 4 0 both eject ink between the arrows A 1 and A4 of the line 2 1 6 and the line 2 2 0 at time t 3 At this time, the fourth scan is performed, and all the nozzles 1 2 in the second line 30 eject ink between the arrows A 2 and A 5 in the line 2 2 4. Similarly, at 14 o'clock, the fifth scan is performed, and all the nozzles 1 1 2 in the first row 20 and the second row 30 will be between the arrows A 3 and A 6 on line 2 2 8 and line 2 3 2 Spit ink. 1232177 V. Description of the invention (7) Once the sixth scan at time t 5 is reached, only the first two-thirds of the print head 10 is above the arrow A 6, so only the bottom of the image will be printed . Since the nozzles 1 1 2 in the second row 30 and the third row 40 will eject ink during the sixth scan, only the fourth region 3 2, the fifth region 34, the seventh region 4 2 and the first The nozzles 1 1 2 of the eight area 4 4 will eject ink. Finally, the seventh scan is performed, and only the first third of the print head 10 is above the arrow A 6. Since only the second row 30 will eject ink, only the nozzles 1 12 in the fourth region 32 will eject ink. One thing to note is that in the seven scans shown in Figure 4, because the second line 30 will eject three different colors of ink, the second line 30 will eject ink during each scan. On the other hand, the first line 20 ejects ink only during the second and fifth scans, and the third line 40 ejects ink only during the third and sixth scans. Therefore, the first line 20 and the third line 40 eject ink every three scans, and the second line 30 ejects ink every time. Although the example in FIG. 4 shows that the first line 20 and the third line 40 eject ink in different scanning terms, in fact, it is also possible to eject ink in the same scan. In order to be more efficient in each scan, the print head 10 should only be able to eject ink from the three areas of the first line 20 and the third line 40 at any time. Of course, it is also possible to eject ink from only two of the three areas. In this case, the first line 20 and the third line 40 are printing.

第13頁 1232177 五、發明說明（8) 頭每兩次或每一次掃描媒介的期間都可以喷出墨水。請參閱圖五，圖五係顯示有一故障喷嘴3 5之列印頭 1 0。因為列印頭1 0在某個程度上提供了過多的顏色墨水，因此可用來填補故障喷嘴3 5的闕漏。包含列印頭1 0 之喷墨印表機可自動地檢測故障喷嘴3 5或者喷墨印表機的使用者可手動地輸入此資訊。舉例來說，圖五顯示了第五區域3 4用來喷出洋紅色墨水的故障喷嘴3 5。在第一行2 0中，第一區域2 2、第二區域2 4以及第三區域2 6都有對應於第二行3 0之第五區域3 4的故障喷嘴3 5的填補喷嘴 2 5。故障喷嘴3 5原來是要喷出洋紅色墨水，而填補喷嘴是喷出淡洋紅色墨水。因此填補喷嘴2 5會在對應於故障喷嘴3 5之位置喷出墨水兩次。請參閱圖六，並參考圖五。圖六係本發明之填補列印頭1 0之故障喷嘴3 5之時序圖3 0 0。如圖四之時序圖2 0 0 所示，時序圖3 0 0的七次掃描中，圖像會在箭頭A 1以及A 6 之間列印出來。圖六與圖四主要的差異在於圖六有用來填補第二行3 0之第五區域3 4的故障喷嘴3 5的填補線3 0 2、 314、322、33 4以及342。因為第一行2 0—般來說是每掃描三次喷出一次墨水，所以在該次掃描的前後可用來填補故障喷嘴3 5。在第一次的掃描中，第二行3 0之第五區域3 4不會喷Page 13 1232177 V. Description of the invention (8) The ink can be ejected every time the head scans the medium twice. Please refer to FIG. 5, which shows a print head 10 with a defective nozzle 35. Because the print head 10 provides too much color ink to a certain extent, it can be used to fill up the faulty nozzle 35. An inkjet printer including a print head 10 can automatically detect a defective nozzle 35 or the user of the inkjet printer can manually enter this information. For example, Fig. 5 shows a faulty nozzle 35 in which the fifth area 34 is used to eject magenta ink. In the first row 20, the first region 22, the second region 24, and the third region 26 each have a filling nozzle 2 5 corresponding to the faulty nozzle 3 5 of the fifth row 34 of the second row 30. . The malfunctioning nozzle 35 was originally intended to eject magenta ink, and the filling nozzle was intended to eject light magenta ink. Therefore, the filling nozzle 25 ejects the ink twice at the position corresponding to the defective nozzle 35. Please refer to Figure 6 and refer to Figure 5. FIG. 6 is a timing chart 3 0 of the defective nozzle 35 of the filling head 10 of the present invention. As shown in the timing diagram 2 of the fourth figure, in the seven scans of the timing diagram 3, the image is printed between the arrows A 1 and A 6. The main difference between Figure 6 and Figure 4 is that Figure 6 has filling lines 3 0 2, 314, 322, 33 4 and 342 for filling the defective nozzles 35 of the fifth row 34 of the second row 30. Because the first line 20 is generally ejected once every three scans, it can be used to fill the defective nozzles 35 before and after the scan. In the first scan, the third row of the third row of 30 will not spray.

第14頁 1232177 五、發明說明（9) 出洋紅色墨水。然而，因為第五區域3 4會於第二次掃描期間在箭頭A 1以及A 2之間喷出墨水，所以在第一次掃描期間，填補線3 0 2—定會被列印出來。因為第三區域2 6在箭頭A 1以及A 2之間，所以第三區域2 6之填補喷嘴會在填補線3 0 2上噴出墨水。線3 0 4也會在列印頭1 0的正常操作下，在第一次掃描期間列印出來。在第二次的掃描時，線3 0 8以及故障線3 1 2通常會被列印出來。在第三次的掃描時，填補線31 4會隨著故障線 3 1 6以及正常線3 2 0—起列印出來。填補線3 1 4係用來填補箭頭A1以及A2之間的故障線31 2、箭頭A2以及A3之間的故障線31 6以及箭頭A3以及A4之間的故障線324。第四次的掃描時，填補線3 2 2則會隨著故障線3 2 4— 起列印出來。填補線3 2 2係用來填補箭頭A2以及A3之間的故障線316、箭頭A3以及A4之間的故障線3 24以及箭頭A4 以及A 5之間的故障線3 3 2。第五次掃描時，線3 2 8以及故障線3 3 2通常會被列印出來。在第六次的掃描時，填補線3 3 4會隨著故障線3 3 6 以及正常線3 4 0—起列印出來。填補線3 3 4係用來填補箭頭A4以及A5之間的故障線3 3 2以及箭頭A5以及A6之間的故障線3 3 6。第七次掃描時，填補線3 4 2會隨著正常線3 4 4列印出來。填補線342係用來填補箭頭A5以及A6之間的故障Page 14 1232177 V. Description of the invention (9) Magenta ink is produced. However, because the fifth area 34 ejects ink between the arrows A 1 and A 2 during the second scan, during the first scan, the fill line 3 0 2-will be printed. Since the third area 26 is between the arrows A 1 and A 2, the filling nozzle of the third area 26 will eject ink on the filling line 3 0 2. Line 3 0 4 is also printed during the first scan under normal operation of print head 10. During the second scan, line 3 0 8 and fault line 3 1 2 are usually printed. During the third scan, the filling line 31 4 will be printed out along with the fault line 3 1 6 and the normal line 3 2 0.

第15頁 1232177 五、發明說明（ίο) 線 3 3 6 〇顯而易見地，第一行2 0在第二次以及第五次掃描中，分別列印出正常線3 0 8以及3 2 8。這表示所有其餘的掃描皆可利用第一行2 0列印填補線。填補線3 0 2、3 1 4、 3 2 2、3 2 4以及3 4 2都分別地在第一次、第三次、第四次、第六次以及第七次掃描中列印出來。除了單一列印頭1 0之第一行1 0、第二行3 0以及第三行4 0之噴嘴外，本發明還可使用兩個甚至更多的列印頭。舉例來說，第一列印頭上可裝置第一行2 0以及第三行4 0喷嘴，另外可在另一列印頭上裝設第二行3 0喷嘴。此項裝置除了使用較簡單的列印頭構造外，也可同時達成本發明之目標。總而言之，列印頭1 0的構造讓列印頭1 0在不需要額外的掃描下，能填補故障喷嘴3 5。原本應該由故障喷嘴 3 5所列印的洋紅色點由喷出淡洋紅色墨水的填補喷嘴2 5 以喷出兩次墨水來填補。在洋紅色墨水的顏色彩度以及明度約為淡洋紅色墨水的兩倍情況下，此填補機制方能運作最佳。雖然本實施例僅使用淡洋紅色以及洋紅色墨水，但同樣可應用在淡青色以及青色墨水上。同樣地，在青色墨水的顏色彩度以及明度約為淡青色墨水的兩倍情況下，填補機制也才會完善有效。除此之外，第一行Page 15 1232177 V. Description of the invention (ίο) Line 3 3 6 〇 Obviously, in the second and fifth scans, the first line 20 prints the normal lines 3 0 8 and 3 2 8 respectively. This means that all remaining scans can use the first line of 20 to fill the line. Filling lines 3 0 2, 3 1 4, 3 2 2, 3 2 4 and 3 4 2 are printed in the first, third, fourth, sixth and seventh scans, respectively. In addition to the nozzles of the first row 10, the second row 30, and the third row 40 of a single print head 10, the present invention can also use two or more print heads. For example, a first row of 20 nozzles and a third row of 40 nozzles can be installed on the first print head, and a second row of 30 nozzles can be installed on the other print head. In addition to using a simpler print head structure, this device can also achieve the goals of the present invention. All in all, the structure of the print head 10 allows the print head 10 to fill the defective nozzle 35 without the need for additional scanning. The magenta dots that should have been printed by the defective nozzle 3 5 were filled by the filling nozzle 2 5 that ejected light magenta ink to eject the ink twice. This filling mechanism works best when the color saturation and lightness of the magenta ink is approximately twice that of the light magenta ink. Although this embodiment uses only light magenta and magenta inks, it can also be applied to light cyan and cyan inks. Similarly, the filling mechanism will be perfect and effective only when the color saturation and lightness of the cyan ink are approximately twice that of the light cyan ink. Beyond that, the first line
