Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printing, and in particular to a method, device, and printer for dynamically adjusting the printing spacing between adjacent label images. Background Art

[0002] After a label inkjet printer completes label printing, a die-cutting knife is required to cut the printed label image to complete the production of a single label. When printing labels, a certain area is often reserved between each label image to facilitate cutting after printing is completed. The distance of this area is denoted as the label image spacing. As Figure 1a shown, it is often required that the label image spacing between each label image 1 is the same during cutting, because during the cutting process, the die-cutting knife cuts according to the reserved label image spacing, and the cutting spacing is fixed and unchanged throughout the cutting process.

[0003] When an existing label printer performs label printing, an image printing spacing is often set in the control software, that is, the distance between the end of the previous image printing and the start of the next image printing, and the image printing spacing is fixed and unchanged. When there is no need to print color target images or color bar images, the label image spacing is the image printing spacing. However, in some printing applications, color target images or color bar images may be printed between each label image. For example, it may be as Figure 1b shown, a color target image 2 and a color bar image 3 are printed after printing a label image 1, or a color bar image 2 is printed after several label images 1 are spaced apart. As Figure 1c shown, a color bar image 3 is printed every time two label images 1 are printed. Then, the first label image spacing and the second label image spacing will be different. When performing label cutting, the area between two adjacent label images 1 will be cut off. However, considering that the die-cutting knife cutting spacing is preset and fixed, whether the cutting spacing is selected to be the same as the first label image spacing or the same as the second label image spacing, some label images 1 cannot be correctly cut.

Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0046] Embodiment 1

[0047] Please refer to Figure 2 , the embodiment of the present invention provides a method for dynamically adjusting the printing spacing between adjacent label images. This method is applicable to label inkjet printers, such as Single-Pass label inkjet printers. In this embodiment, taking the Single-Pass label inkjet printer as an example, when printing label images, a color bar image and / or a color strip image is printed between two adjacent label images. Specifically, the method includes the following steps:

[0048] S1: Obtain the distance between two adjacent label images, denoted as the label image spacing;

[0049] S2: Obtain the preset image height;

[0050] S3: Determine the image printing spacing according to the label image spacing and the preset image height, where the image printing spacing is the distance that the print head moves relative to the printing medium from the end of the printing of the previous preset image to the start of the printing of the next label image.

[0051] Before printing label images, a certain area should be reserved in advance to facilitate the cutting of label images. The distance of this area is denoted as the label image spacing. The label image spacing is generally set according to the actual application scenario. For example, to save printing medium, the label image spacing reserved between two adjacent label images can be smaller. In some printing applications, a color bar image or a color strip image is printed between two adjacent label images (printing a color bar image can be used for the precise positioning of label images, and printing a color strip image can facilitate the moisturizing of the print head). Then it is required that the label image spacing be greater than or equal to the sum of the height of the color bar image and the height of the color strip image. Preferably, the label image spacing is greater than the sum of the height of the color bar image and the height of the color strip image to facilitate the cutting of label images and prevent cutting the edge of the label image.

[0052] In order to accurately cut the label images, it is necessary to determine the image printing spacing according to the height of the color bar image and the height of the color scale image. The height of the color bar image and the height of the color scale image vary according to different printing systems or printing devices, and can be obtained from the parameters set in the printing system during the actual printing process.

[0053] In one embodiment, when printing the color bar image and the color scale image between two adjacent label images simultaneously, the image printing distance is calculated by the following preset formula:

[0054] Hp = Hl - N × Hc - M × Ht, where Hp is the image printing spacing, Hl is the label image spacing, Hc is the height of the color bar image, Ht is the height of the color scale image, N is the number of color bar images, M is the number of color scale images, and N and M are natural numbers greater than or equal to 0.

[0055] As Figure 3 shown, a color scale image and a color bar image are printed between two adjacent label images. Among them, Hc is the height of the color bar image 3, Ht is the height of the color scale image 2, and Hl is the spacing between two adjacent label images 1. When Hl remains unchanged, it can be known that the image printing distance Hp = Hl - Hc - Ht. That is, after printing the color bar image 3, the print head moves Hp relative to the printing medium and then starts to print the next label image 1. Since in a Single-Pass printer, the print head is fixed and the printing medium moves, and the print head sprays ink on the printing medium to print images, when using a Single-Pass printer, after the print head finishes printing the label image 1, the color scale image 2 and the color bar image 3, the printing medium moves Hp, and then the print head is controlled to start printing the next label image 1.

[0056] Printing the color scale image can be used for printing position control to make the positioning accurate when printing label images; printing the color bar image can play a role in moisturizing the print head that is not used when printing label images. Because when printing label images, not all print heads or nozzles may be used for printing. If these nozzles are not used for a long time, the ink in the nozzles may dry up and block the nozzles. Therefore, during the gap of printing label images, the print heads or the nozzles in the print heads that do not participate in the printing of label images spray ink to print the color bar image, so as to moisturize the print head and prevent the nozzles in the print head from being blocked. The method of dynamically adjusting the image printing spacing can ensure that the label images can be correctly cut when both the color scale image and the color bar image are printed.

[0057] In one embodiment, as Figure 4As shown, when only printing a color bar image 2 between two labels, the image printing distance Hp = Hl - Ht. At this time, the height Hc of the color bar image 3 takes a value of 0; after the print head finishes printing the label image 1 and the color bar image 2, after the printing medium moves Hl - Ht, it starts to print the next label image 1.

[0058] Printing the color bar image can be used for print position control, so that the positioning is accurate when printing the label image. When most of the nozzles in the print head are involved in printing the label image, the printing of the color bar image can be omitted to save ink. Adopting the method of dynamically adjusting the image printing interval according to the actual printing situation can ensure that the label image can be correctly cut when printing the color bar image between label images.

[0059] In one embodiment, as Figure 5 shown, when only printing a color bar image 3 between two labels, the image printing distance Hp = Hl - Hc; after the print head finishes printing the label image 1 and the color bar image 3, after the printing medium moves Hl–Hc, it starts to print the next label image 1.

[0060] Because the print control information sent by the host computer when printing the label image already contains the label image position information, all color bar images can be omitted, and only the color bar image is printed to moisturize the print head nozzles not used when printing the label image, preventing the nozzles in the print head from being blocked. Adopting the method of dynamically adjusting the image printing interval according to the actual printing situation can ensure that the label image can be correctly cut when printing the color bar image between label images.

[0061] In one embodiment, as Figure 6 shown, printing a color bar image 2 between two adjacent labels, and printing a color bar image 3 every two label images 1. When not printing the color bar image 3, the image printing distance Hp = Hl - Ht; at this time, after the print head finishes printing the label image 1 and the color bar image 2, after the printing medium moves Hl - Ht, it starts to print the next label image 1; after printing the next label image 1, it is also necessary to print a color bar image 2 and a color bar image 3. Then at this time, the image printing distance Hp' = Hl - Hc - Ht, that is, after the print head finishes printing the label image 1, the color bar image 2 and the color bar image 3, after the printing medium moves Hl - Hc - Ht, it starts to print the next label image 1. In this embodiment, the image printing distance will change dynamically according to whether to print the color bar image 3 or not, so that the spacing of the label images 1 can be ensured to be unchanged, thus ensuring that the die cutter can correctly cut the label image 1.

[0062] Printing a color bar image between label images can moisturize the print head. By printing a color bar image every several label images instead of printing a color bar image after each label image, it can protect the print head and save ink at the same time. Using the method of dynamically adjusting the image printing interval can ensure the correct cutting of label images when printing color bar images at intervals.

[0063] In one embodiment, as Figure 7 shown, print a color scale image 2 between two labels, and print a color bar image 3 every two label images 1, and the number of color bar images 3 printed each time may be different. When not printing the color bar image 3, the image printing distance Hp = Hl – Ht; that is, when the print head finishes printing the label image 1 and the color scale image 2, after the printing medium moves Hl – Ht, start printing the next label image 1. When printing the color bar image 3;

[0064] After printing a label image 1, then print a color scale image 2 and a color bar image 3. At this time, the image printing distance Hp’ = Hl - Hc - Ht, that is, when the print head finishes printing the color bar image 3, after the printing medium moves Hl - Hc - Ht, start printing the next label image 1;

[0065] After printing a label image 1, then print a color scale image 2 and two color bar images 3. At this time, calculate the image printing distance Hp” = Hl - 2Hc - Ht, that is, when the print head finishes printing the color bar image 3, after the printing medium moves Hl - 2Hc - Ht, start printing the next label image 1.

[0066] In one embodiment, as Figure 8 shown, when printing both the color scale image 2 and the color bar image 3, and there is a spacing Hw between the color scale image 2 and the color bar image 3, the image printing distance Hp = Hl - Hc - Ht - Hw, that is, after printing a label image 1, then print a color scale image 2, after the printing medium moves Hw and then print the color bar image 3, after printing the color bar image 3, wait for the printing medium to move Hp = Hl - Hc - Ht - Hw and then start printing the next label image 1.

[0067] Printing a color bar image between label images can keep the print head moisturized. Instead of printing a color bar image after each label image, printing a color bar image at intervals of several label images can protect the print head and save ink at the same time. Additionally, for some nozzles in the print head that are not actually used for a long time, multiple color bar images can be continuously printed by controlling them, which helps to wash away the dried ink blocking the nozzles during inkjet printing, facilitating the recovery and moisturization of the blocked nozzles. Using the method of dynamically adjusting the image printing interval can ensure that label images are correctly cut regardless of how many label images are skipped to print a color bar image or how many color bar images are printed.

[0068] In one embodiment, when printing a color target image or a color bar image, first determine whether the label image interval is greater than the height of the color target image or the color bar image or the sum of the heights of the color target image and the color bar image. If the label image interval is less than both the height of the color target image and the height of the color bar image, and color target image printing and color bar image printing cannot be performed between adjacent label images, then the print head does not print the color target image and the color bar image; when the label image interval is greater than the height of the color target image but less than the height of the color bar image, only the color target image is printed in adjacent label images; when the label image interval is only slightly greater than the height of the color bar image but less than the sum of the heights of the color target image and the color bar image, adjust the printing position of the color target image and only print the color bar image in the label image; as Figure 9 shown, the color target image can be printed in the blank area on the left or right of the label image, thus avoiding the problem of insufficient printing space when it is necessary to print color targets and color bar images. The specific steps are as follows:

[0069] Obtain the distance between two adjacent label images, denoted as the label image interval;

[0070] Obtain the heights of the color target image and the color bar image;

[0071] When the label image interval is greater than the height of the color target image and less than the height of the color bar image, determine the image printing interval according to the label image interval and the height of the color target image, and only print the color target image between two adjacent label images;

[0072] When the label image interval is greater than the height of the color bar image and less than the sum of the heights of the color target image and the color bar image, determine the image printing interval according to the label image interval and the height of the color bar image, and only print the color bar image between two adjacent label images;

[0073] When the label image interval is less than the height of the color bar image and less than the height of the color target image, the image printing interval is equal to the label image interval, and control the print head not to eject ink to print the color target image and the color bar image;

[0074] When there are unused nozzles beside the nozzles for printing label images and the width of the images printed by all unused nozzles is greater than the width of the color bar image, control the unused nozzles to print the color bar image.

[0075] In this embodiment, first, it is determined whether the color bar image and the color strip image can be printed in two adjacent labels according to the label image spacing, the color bar image height, and the color strip image height. When there is only space for printing the color strip image, it is preferably to print the color strip image to moisturize the unused nozzles. Since the color bar image is not limited to being printed between two adjacent label images, it can be printed on the left or right side of the label image, which does not affect the printing positioning when printing the label image. Therefore, the unused nozzles on both sides of the nozzle for printing the title image can be used for printing. When the width of the image printed by the unused nozzles is greater than the color bar image, these unused nozzles can be controlled to print the color bar image on the left or right side of the label image. If the label image spacing is less than both the color bar image height and the color strip image height, that is, the space between adjacent label images cannot meet the printing of the color bar image or the color strip image, then it is preferably to print the label image, control the nozzles not to eject ink to print the color bar image or the color strip image, and ensure the normal printing of the label image.

[0076] In summary, the method for dynamically adjusting the printing spacing of adjacent label images in this embodiment dynamically changes the image printing distance according to whether the color bar image or the color strip image is printed in two adjacent label images, ensures that the label image spacing remains unchanged, and thus ensures that the die cutter can correctly cut the label image. Printing the color bar image between label images can perform precise positioning printing on the label image, while printing the color strip image between label images can play a role in moisturizing the nozzles. Printing the color strip image once every several label images can protect the nozzles and save ink at the same time. The method of dynamically adjusting the image printing spacing can ensure the correct cutting of the label image when printing the color strip image at intervals.
