Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printing, and particularly to a method, device, equipment and storage medium for dynamically adjusting the image interval paper feeding distance. Background Art

[0002] In inkjet printing applications, multiple images are often printed continuously, that is, after one image is printed, the next image is printed on the same printing medium. To avoid overlapping of two continuously printed images, after one image is printed, the printing device is paused, and then the operator manually moves the printing medium (also known as paper feeding), so that there is a certain blank distance between the start printing position of the next image and the end printing position of the previous image, and then the printing device is started to print the next image. This manual paper feeding method requires labor, resulting in increased labor costs and low work efficiency. In addition, there is another paper feeding method: a fixed paper feeding distance is set in the printing control software. When one image is printed, after the control drive device drives the printing medium to move a fixed distance relative to the nozzle, the next image is printed. This fixed paper feeding method has higher efficiency compared to the manual paper feeding method. However, due to the fixed paper feeding distance, the paper feeding distance cannot be flexibly adjusted according to the image printing situation, which is likely to cause too small an image spacing affecting the printing effect or too large a spacing resulting in waste of the printing medium.

[0056] Embodiment 1

[0057] An embodiment of the present invention provides a method for dynamically adjusting the image interval paper feeding distance. This method is applicable to a reciprocating scanning inkjet printing device. The reciprocating inkjet printing device includes at least one print head. The print head includes at least one row of nozzles. The nozzles eject ink droplets onto a printing medium to form a printed image. As Figure 1 shown is a schematic structural diagram of a reciprocating scanning inkjet printing device. The print head 1 is arranged on the cross beam 5. The cross beam 5 is arranged above the printing platform 3. The printing medium 2 is placed on the surface of the printing platform 3. During printing, the control makes the print head 1 reciprocate in the X-axis direction and the printing medium move forward in the Y-axis direction (or the print head move forward in the Y-axis direction) alternately to print an image onto the printing medium 2. Denote the movement direction of the print head 1 from left to right along the X-axis as the forward direction, and the movement direction from right to left as the reverse direction. One scan and print of the print head 1 in the forward direction or the reverse direction is called one PASS. When reciprocating printing, after controlling the print head 1 to scan once in the forward direction and eject ink droplets onto the printing medium 2 to complete one PASS of printing, after controlling the printing medium 2 to move a certain distance in the Y direction (also called paper feeding), control the print head 1 to scan once in the reverse direction and eject ink droplets to complete the next PASS of printing. Reciprocating scanning and inkjetting are performed in this way to complete the printing of an image.

[0058] Please refer to Figure 2 , the method for dynamically adjusting the image interval paper feeding distance specifically includes the following steps:

[0059] S1: Obtain the printing height of the current printed image at the last printing, denoted as the first printing height;

[0060] S2: Obtain the distance between the current printed image and the next image to be printed adjacent to it, denoted as the first distance;

[0061] S3: Obtain the printing height of the next image to be printed at the first printing, denoted as the second printing height;

[0062] S4: Obtain the image interval paper feeding distance according to the first printing height, the first distance, and the second printing height. The image interval paper feeding distance is the distance that the print head moves relative to the printing medium from the completion of the current printed image to the start of the printing of the next image to be printed.

[0063] Specifically, the printing height of the current printed image during the last printing refers to the printing height during the last PASS printing of the current printed image, denoted as the first printing height. After multiple reciprocating scans, when the print head performs one PASS printing along the forward or reverse direction, the currently printed image is completed. After that, the print medium (or the print head) needs to be moved so that the print head moves a certain distance in the Y direction relative to the print medium (i.e., the image interval paper feed distance), and the printed image that has been completed leaves the scanning range of the print head. The print head can start printing the next image to be printed in the blank printing area on the print medium. When starting to print the next image to be printed, similarly, the print head starts the first PASS printing along the reverse direction (or the forward direction). The printing height during this first PASS printing is the printing height of the next image to be printed during the first printing, denoted as the second printing height. In the embodiments of the present invention, the image interval paper feed distance is flexibly determined by obtaining the first printing height, the second printing height, and the distance between two continuously printed images.

[0064] Preferably, please refer to Figure 3 , the obtaining of the printing height of the current printed image during the last printing, denoted as the first printing height, includes:

[0065] S31: Respectively obtain the image accuracy and printing accuracy of the current printed image, denoted as the first image accuracy and the first printing accuracy;

[0066] S32: Determine the first scanning number according to the first image accuracy and the first printing accuracy;

[0067] S33: Obtain the print head height and the image height of the current printed image, denoted as the first image height;

[0068] S34: Determine the first printing height according to the first scanning number, the print head height, and the first image height.

[0069] Specifically, when performing image printing, printing parameters such as the number of scans and the stepping height need to be determined according to the image precision and the printing precision of the printing device. Denote the image precision of the currently printed image as the first image precision, and denote the printing precision of the currently printed image as the first printing precision. According to the first image precision and the first printing precision, the number of scans for the currently printed image can be obtained, which is the first number of scans. Here, the number of scans refers to the number of times the print head reciprocally scans when printing the image of the unit area. Exemplarily, if the first image precision is 720 dpi×720 dpi and the printing precision is 360 dpi×360 dpi, then the first number of scans is 4, that is, 4PASS printing. Here, the print head height refers to the maximum printing height that can be achieved when the print head scans once along the printing direction. According to the print head height and the first number of scans, the printing height for each PASS printing and the stepping height of the print head between each PASS can be obtained. Finally, in combination with the image height of the currently printed image (denoted as the first image height), the printing height at the last PASS printing can be known, that is, the first printing height.

[0070] Preferably, please refer to Figure 4 , determining the first printing height according to the first number of scans, the print head height, and the first image height includes:

[0071] S41: Determine the printing height of the first unit image according to the first number of scans and the print head height;

[0072] S42: Determine the height of the unit image of the last print of the currently printed image according to the first image height and the printing height of the first unit image, denoted as the height of the last unit image;

[0073] S43: Determine the first printing height according to the height of the last unit image.

[0074] Specifically, according to the print head height and the first number of scans, the printing height for each PASS printing can be obtained, which is the printing height of the first unit image. Exemplarily, if the print head height is 360d (d represents the height of one pixel) and the number of scans is 4, then the printing height for each PASS printing or the printing height of the first unit image is 360 / 4 = 90d. If the obtained first image height is 1440d, 1440 % 90 = 0, and 1440 / 90 = 16, then it can be known that the height of the unit image of the last print (that is, the height of the last unit image) is 90d. When performing the 16th scan, it is the last print of the currently printed image, and the first printing height at this time is 90d. If the obtained first image height is 1420d, then 1420 % 90 = 70d, and It can be known that the height of the unit image printed last time (i.e., the height of the last unit image) is 70d. When the 16th scan is performed, it is the last print of the current printed image, and the first print height is 70d at this time.

[0075] Preferably, please refer to Figure 5 , obtaining the distance between the current printed image and the next image to be printed adjacent to it, denoted as the first distance, includes:

[0076] S51: Obtain the number and height of all images to be printed in the printing task before starting printing;

[0077] S52: Obtain the length of the printing medium;

[0078] S53: Determine the first distance according to the length of the printing medium, the number and height of all images to be printed.

[0079] Specifically, when multiple images are continuously printed in the printing task, a certain blank space needs to be left between adjacent two images to avoid affecting the printing effect of the images. In one embodiment, the distance between adjacent two images can be determined by the printing control software of the printing system according to the number of images to be printed in the printing task, the height of each image to be printed in the Y direction, and the length of the printing medium in the Y direction. Exemplarily, when the length of the printing medium is 2.5m, the number of images to be printed is 5, and the height of each image to be printed is 0.3m. At this time, the printing control software can automatically calculate the distance between each image according to these parameters. Exemplarily, such as 0.1m or 0.2m. The image distance here is the distance between the current printed image and the next image to be printed, that is, the first distance.

[0080] In another embodiment, the image distance can also be adjusted in real time according to the actual printing situation. Preferably, please refer to Figure 6 , obtaining the distance between the current printed image and the next image to be printed adjacent to it, denoted as the first distance, includes:

[0081] S61: Obtain the length of the remaining blank printing medium when the last print of the current printed image is completed;

[0082] S62: Obtain the number and height of other images to be printed that have not been printed yet except the current printed image in the printing task;

[0083] S63: Determine the first distance according to the length of the remaining blank printing medium, the number and height of other images to be printed that have not been printed yet, the height of the current printed image, and the height of the next image to be printed.

[0084] Specifically, obtaining the length of the remaining blank printing medium needs to be determined based on the length of the entire printing medium and the length of the printed printing medium. The length of the printed printing medium can be determined by reading the paper feed length of the printing medium from the start of printing to the current printed image. Subtracting the paper feed length from the length of the entire printing medium can determine the length of the remaining blank printing medium. Then, dynamically determine the distance between the current printed image and the next image to be printed by integrating the height of the current printed image, the height of the next image to be printed, and the heights of the other unprinted images to be printed other than the current printed image. Exemplarily, if the length of the remaining blank printing medium is large, the number of other unprinted images to be printed is small, the height of the current printed image is large, and the height of the next image to be printed is large, the distance between the current printed image and the next image to be printed can be appropriately increased at this time. In other embodiments, a mathematical model for dynamically adjusting the image spacing can also be embedded in the printing control software. This mathematical model can dynamically adjust the spacing between the current printed image and its adjacent next image to be printed according to the length of the entire printing medium, the length of the remaining blank printing medium, the height of the current printed image, the height of the next image to be printed, and the number and height of all other unprinted images other than the current printed image.

[0085] In another embodiment, the first distance can also be determined according to the distance value externally input through the human-computer interaction interface of the printing device. Exemplarily, when the current image printing is almost completed, the human-computer interaction interface of the printing device can prompt the user to input the spacing between it and the next image to be printed. The user can input a distance value according to the actual situation. To ensure that the images do not overlap and have a good printing effect, due to factors such as mechanical errors and ink drop landing point drift, if the distance value set by the user is too small, it may still cause the images to overlap and affect the printing effect. Preferably, a preset distance threshold is first set. Only when the distance value input by the user is greater than or equal to the preset distance threshold, the first distance is set to the value input by the user. The preset distance threshold here can be determined by repeatedly printing and testing to obtain the mechanical error and ink drop landing point drift values of the printing device.

[0086] Preferably, please refer to Figure 7 , obtaining the printing height of the next image to be printed during the first printing, denoted as the second printing height includes:

[0087] S71: Obtain the image accuracy and printing accuracy of the next image to be printed, denoted as the second image accuracy and the second printing accuracy;

[0088] S72: Determine the second scanning times according to the second image accuracy and the second printing accuracy;

[0089] S73: Obtain the image height of the next image to be printed, denoted as the second image height;

[0090] S74: Determine the second printing height according to the second scanning times, the print head height, and the second image height.

[0091] Specifically, record the image precision of the next image to be printed as the second image precision, and the printing precision as the second printing precision. Preferably, the printing precision can be adjusted according to the corresponding image precision. When the image precision is higher, the printing precision can be adjusted by adjusting the firing frequency of the print head. According to the second image precision and the second printing precision, the scanning times of the current printed image can be obtained, which is the second scanning times. Exemplarily, if the second image precision is 720 dpi×960 dpi and the printing precision is 360 dpi×480 dpi, then the second scanning times is 4, that is, 4PASS printing. According to the print head height and the second scanning times, the printing height of each PASS printing and the stepping height of the print head between each PASS can be obtained. After obtaining the height of each PASS printing, the printing height of the first PASS printing of the next image to be printed can be known, that is, the second printing height. Exemplarily, if the print head height is 360d (d represents the height of a pixel) and the scanning times is 4, then the printing height of each PASS is 90d, and the second printing height is 90d.

[0092] Preferably, the obtaining the image interval paper feed distance according to the first printing height, the first distance, and the second printing height includes:

[0093] Obtain the image interval paper feed distance according to the following formula:

[0094] z = h 1 + l 1 - h 2

[0095] where z is the image interval paper feed distance, h 1 is the first printing height, l is the first distance, and h 2 is the second printing height.

[0096] After obtaining the first printing height, the first distance, and the second printing height, calculate the image interval paper feed distance according to the above formula. The printing device controls the transmission mechanism of the printing medium to move the printing medium (or controls the print head moving mechanism to move the print head) by the corresponding distance after completing the current image printing, and the print head starts to print the next image to be printed.

[0097] In summary, the method for dynamically adjusting the image interval paper feed distance provided by the embodiment of the present invention obtains the printing height of the current printed image at the last printing, denoted as the first printing height; obtains the distance between the current printed image and the next to-be-printed image adjacent thereto, denoted as the first distance; obtains the printing height of the next to-be-printed image at the first printing, denoted as the second printing height; and obtains the image interval paper feed distance according to the first printing height, the first distance, and the second printing height. The method of the present invention can dynamically adjust the image interval paper feed distance when printing two adjacent images according to the height of the current printed image at the last printing, the printing height of the next to-be-printed image at the first printing, and the image spacing, thereby ensuring that the image spacing is controllable and avoiding image overlap or too small spacing affecting the printing quality, and also avoiding waste of printing media due to too large image spacing, and at the same time improving the overall printing efficiency of the printing task.
