Description

Intelligent curing method, device, equipment and storage medium for ink-jet printing

Technical Field

Background

Along with the continuous expansion of the application field of industrial inkjet printing, the demands for customizing images are more and more, and the colors and the concentrations of different images are different, so that the ink needs to be ensured to be adsorbed or fixed on the printing medium quickly without being diffused when the images with different color concentrations are printed because the ink is sprayed on the printing medium with specified materials quickly in the inkjet printing process, so that the best image printing effect is formed.

It is currently common to rapidly cure an image (ink) on a material by a heating/curing device to enhance the ink absorption effect of the material. However, the scheme has some drawbacks, because the curing power of the curing device is always fixed when the curing device is used for curing the images, and the fixed power curing cannot be suitable for the images with different ink volume concentrations, for example, when the curing power is adjusted to be suitable for the power of the images with thicker ink volume, the excessive curing or overheating of the images can be caused when the ink volume of the images is shallower, so that the printing medium is deformed, damaged and the like; otherwise, it may not be possible to cure an image with a relatively high ink content, causing the ink to spread on the material, degrading the image quality.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

Example 1

As shown in fig. 1, after an image is printed by inkjet, the image is cured by a curing device, so that the situation that the image is diffused due to the fact that the ink is not dried during subsequent material collection or the fact that the undried ink is attached to the back surface of a printing medium when the printing medium after printing is stored as a roll or the like is avoided, and the image quality is affected. In the prior art, the power of the curing device is fixed in the whole image curing process, the curing effect is poor in some image areas with larger ink quantity or larger concentration, and the printing medium is deformed or damaged due to excessive curing in some image areas with smaller ink quantity or smaller concentration. Because the embodiment of the invention provides the intelligent curing method for the ink-jet printing, the curing power can be intelligently adjusted according to the ink quantity corresponding to the image, so that the situation of insufficient curing or excessive curing of the image is avoided.

Referring to fig. 2, an embodiment of the present invention provides an intelligent curing method for inkjet printing, which includes:

s1: dividing an image to be printed into a plurality of image units;

s2: acquiring the ink quantity corresponding to each image unit and recording the ink quantity as a first ink quantity;

s3: acquiring the corresponding curing power of each image unit according to the first ink quantity, and marking the curing power as first curing power;

s4: and performing curing treatment on the corresponding image units according to the first curing power.

Specifically, because the curing area in the curing device is limited, the curing device does not cure the whole printed image at one time, but cures the printed partial image at the same time, and the inkjet printer is still printing other partial images at the same time. The image to be printed can thus be divided into several image units (areas), and the corresponding ink quantity per image unit is acquired and noted as the first ink quantity. And acquiring the curing power corresponding to each image unit according to the first ink quantity corresponding to each image unit, marking the curing power as the first curing power, and when the image unit is printed, and moving the curing device, adjusting the power to the curing power corresponding to the image unit by the curing device, and performing heating curing treatment on the image unit. Before printing, a map of ink amount and curing power may be set, for example, how much ink amount corresponds to a large curing power. In one embodiment, the mapping relationship may be a many-to-one mapping relationship, that is, all ink amounts in a certain range correspond to one curing power, and illustratively, when the ink amount is greater than or equal to a and less than or equal to b, the corresponding curing power is m, and when the ink amount is greater than or equal to b and less than or equal to c, the corresponding curing power is n. In another embodiment, the mapping may be a one-to-one mapping, which may be discrete or continuous. Illustratively, when the ink amount is equal to a, its corresponding curing power is m; when the ink amount is equal to b, the corresponding curing power is n, and when the ink amount is equal to c, the corresponding curing power is k. A continuous one-to-one mapping is achieved by creating a function of ink quantity versus curing power. Exemplary, e.g., y=ax, where y is the curing power, x is the ink amount, and a is a coefficient. The curing power can be obtained from the function described above by obtaining the ink amount of the image unit. Therefore, according to the mapping relation, the corresponding curing power of the image unit can be obtained by obtaining the ink quantity of the image unit, so that after the image unit is printed, the power of the curing device is intelligently adjusted according to the ink quantity of the image unit, intelligent curing of the image is realized, the occurrence of insufficient curing or excessive curing is avoided, and the image quality is ensured.

The ink amount of the image unit can be obtained by calculating the print data obtained after RIP processing of the image to be printed, for example, the print data obtained after RIP processing is split according to the image unit, the ink amount of the image unit is obtained according to the ink amount corresponding to each print data of the image unit, and the corresponding ink amount when each image unit is printed can be calculated and counted by using a nozzle driving plate in the printing process.

The division of the image units is performed on the image to be printed, which may be divided according to the actual print job. Taking the shuttle scan inkjet printing as an example, fig. 3 is a schematic diagram when the image to be printed is printed with 4pass printing (the number of scans is 4). In the first Pass, the nozzle moves along the main scanning direction, the ink jet prints the pixel point (1), then the nozzle moves a certain distance relative to the printing medium (the nozzle is fixed, the printing medium moves along the sub-scanning direction or the printing medium is fixed, the jet prints and moves along the sub-scanning direction), the nozzle moves reversely along the main scanning direction, the ink jet prints the pixel point (2), then the nozzle moves a certain distance relative to the printing medium, the nozzle moves along the main scanning direction and jet prints the pixel point (3), after the nozzle moves a certain distance relative to the printing medium, the ink jet prints the pixel point (4) in a reverse direction, and after 4Pass, the printing of the image area A is completed; after printing the 4Pass again, printing of the image area B is completed, and printing is repeated until printing is completed. Therefore, the image to be printed can be divided into image units according to the size of the image area such as A, B, after one image unit is printed every 4Pass, when the image unit moves to the curing device, the curing device adjusts the curing power according to the ink quantity of the image unit, and the heating curing treatment is carried out.

In Single-Pass ink-jet printing, the printing process is paper-feeding imaging once, and partial images cannot be printed after a plurality of Pass are scanned in a reciprocating mode like in reciprocating ink-jet printing. At this time, the image units can be divided according to the maximum curing area of the curing device at a time, then the ink quantity of each image unit is obtained according to the image data corresponding to each image unit, when the Single-Pass printer finishes one image unit through paper feeding printing at a time, the curing device adjusts the curing power according to the ink quantity corresponding to the image unit when the image unit moves to the curing device, and therefore intelligent curing is achieved.

In practical printing applications, cyan ink, magenta ink, yellow ink and black ink, that is, CMYK four-color ink are often used to print color images, and leveling time or curing time of different color inks are different due to different added materials, so that these factors can be taken into consideration to realize intelligent curing and further optimize the image printing effect.

In some embodiments, printing is performed using cyan ink, magenta ink, yellow ink, and black ink, and the obtaining the corresponding ink amount for each image unit, denoted as the first ink amount, includes:

respectively obtaining ink amounts of cyan ink, magenta ink, yellow ink and black ink corresponding to the image unit, wherein the first ink amount is the sum of the ink amounts of the cyan ink, the magenta ink, the yellow ink and the black ink;

the step of obtaining the curing power corresponding to each image unit according to the first ink quantity, wherein the step of obtaining the curing power as the first curing power comprises the following steps:

respectively obtaining leveling time of cyan ink, magenta ink, yellow ink and black ink;

and acquiring the first curing power according to the leveling time of the cyan ink, the magenta ink, the yellow ink and the black ink and the ink quantity.

Specifically, after splitting print data obtained after RIP processing is performed on an image to be printed according to image units, further splitting print data of each image unit according to four channels of CMYK to obtain print data corresponding to each color channel, printing corresponding to print data of a cyan channel by cyan ink, printing corresponding to print data of a magenta channel by magenta ink, printing corresponding to print data of a yellow channel by yellow ink, printing corresponding to print data of a black channel by black ink, and obtaining ink amounts corresponding to inks of various colors according to the print data of various channels. The print data of each image unit is thus actually a combination of print data of each channel, and the sum of the ink amounts corresponding to the inks of the respective colors is the first ink amount. Besides obtaining the ink quantity corresponding to each color channel, the corresponding leveling time of each color ink is obtained, the leveling time of the ink influences the quality of image printing, and the curing time of the ink can be adjusted according to the leveling time of the ink to achieve a better printing effect. Therefore, the power for curing the image unit is obtained by combining the ink quantity and the leveling time corresponding to each color channel in the image unit, so as to control the curing time. The method includes the steps that a weight value is set for each color ink according to ink quantity and leveling time of each color ink, if the ink quantity is larger or the leveling time is longer, the weight is larger, otherwise, the weight is smaller, and finally, the final curing power corresponding to the image unit is obtained by multiplying the weight corresponding to each color ink by a preset curing power, so that intelligent curing is achieved, and meanwhile, the image printing effect is further optimized.

In some embodiments, the image unit is not cured immediately after printing, but rather, it is required to reach the curing device as the print medium moves for a certain time. In order to ensure that when the currently printed image unit reaches the curing device, the curing device correspondingly adjusts the curing power of the currently printed image unit to the curing power corresponding to the ink amount of the image unit, the following steps are needed before curing:

s10: acquiring the time of each printed image unit reaching a curing device, and recording the time as the image reaching time;

s11: and switching the first curing power of the curing device according to the image arrival time.

Further, acquiring the time for each printed image unit to reach the curing device includes:

s101: recording the printing completion time of each image unit;

s102: acquiring the corresponding moving time of each image unit according to the moving speed and the moving distance of the printing medium;

s103: and acquiring the image arrival time according to the printing completion time and the moving time.

When printing is completed for an image unit, the printing completion time of the image unit is recorded. The time for the image unit to reach the curing device from the completion of printing needs to be determined based on the data and distance the image has moved in the secondary process. The moving speed of the image unit is actually the moving speed of the printing medium, the moving speed of the printing medium can be known to be uniform according to the stepping speed of the motor, the moving distance is determined according to the specific position of the curing device in the printing equipment, therefore, the time interval of the image unit reaching the curing device after printing can be known according to the moving distance and the moving speed of the image unit and is recorded as moving time, the printing completion time of the image unit is recorded, the printing completion time and the moving time can be added to obtain the reaching time of the image reaching the curing device, and when the current time is the reaching time corresponding to the image unit, the curing power of the curing device is adjusted to be the corresponding power of the image unit, and the curing treatment of the image unit is carried out.

In some embodiments, the image unit may also be pre-cured/heat treated before reaching the curing device. Therefore, the image unit is not cured immediately after the printing of the image unit is completed, but the image unit needs to be cured as the printing medium moves to the curing device, and if the ink is not fixed or cured, the printing quality of the final image may be affected, at this time, the pre-curing process may be performed immediately before the printing of the image unit is performed or after the printing is completed, and the final curing process may be performed after reaching the curing device.

In one embodiment, when the image element is completed by several scan prints, the image portion of each Pass (one scan print) may be pre-cured after it has been printed. And similarly, according to the ink quantity corresponding to the single-time scanned image, obtaining the pre-curing power corresponding to the single-time scanned image, and marking the pre-curing power as the second curing power, and after each Pass scanning is completed, performing pre-curing treatment on the image (single-time scanned image) of the Pass by using the pre-curing power corresponding to the Pass image (single-time scanned image). The pre-curing may be performed by an accelerated curing device mounted on the printing platform. The method comprises the following specific steps:

s20: acquiring the ink quantity corresponding to the single scanning image and marking the ink quantity as a second ink quantity;

s21: acquiring the curing power corresponding to the single-scanning image according to the second ink quantity, and marking the curing power as second curing power;

s22: and performing pre-curing treatment on the corresponding single-scanning image according to the second curing power.

Preferably, the second curing power is less than the first curing power. Because the second curing power is the power of the pre-curing process, the power can be smaller, and the first curing power is the power when the final curing process is performed, the power of the final curing process can be larger at the moment, and the image can be finally cured. In other embodiments, the second curing power may be greater than the first curing power, so that the image can be substantially cured during the pre-curing process, and the curing function is optimally adjusted during the final curing process to intelligently cure the image.

Before each image unit is cured, when the image unit is printed, each single-time printed image part of the image unit is pre-cured, so that ink diffusion can be avoided, and the printing quality of the image can be improved.

In some embodiments, if the curing device is capable of a zone curing function, the image unit may be divided into a number of sub-image units, each sub-image unit being zone cured with a different curing power according to the amount of ink corresponding to each sub-image unit. The method specifically comprises the following steps:

s40: dividing the image unit into a plurality of sub-image units;

s41: acquiring the ink quantity corresponding to each sub-image unit and recording the ink quantity as a third ink quantity;

s42, acquiring the corresponding curing power of each sub-image unit according to the third ink quantity, and marking the curing power as third curing power;

s43: and carrying out curing treatment on the corresponding sub-image units according to the third curing power.

The step of performing the curing process on the corresponding sub-image unit according to the third curing power includes:

s431: acquiring a solidification area corresponding to each printed sub-image unit;

s432: and carrying out curing treatment on the corresponding sub-image units in the curing area according to the third curing power.

For example, as shown in fig. 4, the image unit a is equally divided into four sub-image units (A1, A2, A3, A4), the corresponding curing device B may be divided into four curing areas (B1, B2, B3, B4), the ink amount of each sub-image unit is obtained before the image unit a is cured, so that the curing power corresponding to each sub-image unit is obtained according to the above-mentioned mapping relationship of the ink amount and the curing power, and is denoted as a third curing power, the sub-image unit A1 corresponds to the third curing power P1, the sub-image unit A2 corresponds to the third curing power P2, the A1 corresponds to the curing power P1, the third curing power corresponding to the A3 corresponds to the third curing power P3, and the third curing power corresponding to the A4 corresponds to the curing power P4, and then, when the image unit reaches the curing device B, the curing area B1 uses the curing power P1 to cure the sub-image unit A1, the curing area B2 uses the curing power P2 to cure the sub-image unit A3, and the curing area B2 uses the sub-image unit P4 to cure the sub-image unit A4.

Of course, the partitioning method of the image unit is not limited to the method illustrated in fig. 4, and may be the method illustrated in fig. 5 or fig. 6. The areas (sizes) of the sub-image units may be equal or unequal, and the number of the sub-image units may be set according to the actual printing situation. Correspondingly, the curing device needs to be structurally adjusted to adapt the curing partition to the partition mode of the image unit.

The image units are subjected to partition curing treatment, and the image areas with different ink amounts in the same image unit can be cured by intelligently adjusting the curing power according to the ink amounts, so that insufficient curing or transition of curing caused by uneven ink amounts of different areas of the same image unit is avoided, the curing effect of the image unit is further ensured, and the image quality is improved.

In summary, according to the intelligent curing method for inkjet printing provided by the embodiment of the invention, the image to be printed is divided into a plurality of image units, the ink quantity of the image units is obtained, and the corresponding curing power is determined according to the ink quantity of the image units, so that after the image units are printed, the power of the curing device is adjusted according to the ink quantity of the image units, intelligent curing of the image units is realized, the occurrence of insufficient curing or excessive curing is avoided, and the image quality is ensured. If the image unit is printed by multiple scanning, further, the image part printed by each scanning of the image unit can be pre-cured when the image unit is printed, so that the diffusion of ink can be avoided, and the printing quality of the image can be improved. After the printing of the image units is finished, the image units are subjected to partition curing treatment, and the image areas with different ink amounts in the same image unit can be cured by intelligently adjusting the curing power according to the ink amounts, so that the defect of insufficient curing or the transition of curing caused by uneven ink amounts in the different areas of the same image unit is avoided, the curing effect of the image units is further ensured, and the image quality is improved.
