Fig. 1 is a flowchart illustrating a method for adjusting printing dots according to an embodiment of the present application, where the method includes the following steps, as shown in fig. 1:
Specifically, the target printing object may be a specific real object such as a picture, paper, a device, and the like, the printing system prints on the target printing object determined by the user, and a film layer is printed on the target printing object by an inkjet method. Before printing, a user can divide a target printing object into a plurality of sub-areas and set the ink jet thickness of printing for each sub-area of the target printing object, and the ink jet thickness of different sub-areas can be the same or different. After acquiring the ink jet thickness set by the user for each sub-area, the printing system determines the maximum ink jet thickness in all the ink jet thicknesses through calculation.
Example 1, when the target print object was divided into four sub-areas, it was assumed that the ink ejection thickness of the first sub-area was 10mm, the ink ejection thickness of the second sub-area was 20mm, the ink ejection thickness of the third sub-area was 30mm, and the ink ejection thickness of the fourth sub-area was 40 mm. Then according to four ink jet thicknesses: 10mm, 20mm, 30mm, 40mm, the maximum ink-jet thickness calculated was: 40 mm.
And 102, calculating the number of printing points of each subarea based on a preset longitudinal resolution, a preset nozzle drop volume and the maximum ink jetting thickness.
Specifically, a nozzle is a device for jetting ink in a printing system, a nozzle drop volume refers to the volume of each drop jetted by the nozzle in the ink jetting process, and the nozzle drop volume is preset. The resolution determines the fineness of the image details, and in general, for the same image, the higher the resolution of the image is, the more pixel points are included, the clearer the image is, and the better the printing quality is. The vertical resolution is the resolution of the printing system on the vertical axis, which represents how many pixels are per unit length of the vertical axis, and by knowing the vertical resolution, the ink jet thickness (here, the maximum ink jet thickness), and the nozzle drop volume, the number of printed dots per sub-area can be determined. In the embodiment of the application, each pixel point is taken as a point to be printed, namely, an ink jet point is to be jetted, so that ink jet operation is performed through the position of the printed point.
And 103, for each sub-area, when the ink jetting thickness of the sub-area is smaller than the maximum ink jetting thickness, reducing the number of the printing points in the sub-area.
Specifically, in the case where the total number of printing dots is fixed, if ink is ejected for each printing dot, the ink ejection thickness is the maximum ink ejection thickness, and similarly, if some printing dots are masked and ink is ejected only for some of the printing dots, the obtained ink ejection thickness is necessarily smaller than the maximum ink ejection thickness, that is, the ink ejection thickness obtained according to the number of printing dots should be the maximum ink ejection thickness. Therefore, for each sub-area, if the ink ejection thickness of the sub-area is smaller than the maximum ink ejection thickness, the number of printing dots in the sub-area should be reduced, so as to achieve the purpose of reducing the ink ejection thickness in the sub-area.
The method for adjusting the printing points, provided by the embodiment of the application, includes the steps that firstly, the ink jet thickness set for each sub-area of a target printing object is determined, so that the maximum ink jet thickness set in the target printing object by a user is determined, and the number of the printing points in each sub-area of the target printing object is determined according to the maximum ink jet thickness, the preset longitudinal resolution and the preset nozzle drop volume, so that the number of the printing points in each sub-area is determined according to the maximum ink jet thickness; for each sub-region, when the actual ink ejection thickness set for the sub-region is smaller than the maximum ink ejection thickness, the number of printing dots in the sub-region is reduced. Compared with the scheme that the volume of the liquid drop is directly changed when the ink-jet thickness is different in the prior art, the method can adjust the number of the printing points according to the requirements of different ink-jet thicknesses under the condition of the fixed volume of the liquid drop of the nozzle, and can solve the problem that the film layer printed by changing the volume of the liquid drop is uneven in the prior art.
In a possible embodiment, when the step 102 is executed, the following steps are specifically included:
step 111, calculating the transverse resolution of the first sub-area corresponding to the maximum ink-jet thickness based on the preset longitudinal resolution, the preset nozzle droplet volume and the maximum ink-jet thickness; determining the total number of printing points in the first sub-area based on the transverse resolution and the longitudinal resolution, and taking the total number as the number of printing points of each sub-area.
Specifically, the horizontal resolution indicates how many pixels are per unit length on the horizontal axis, and the horizontal resolution is the resolution of the printing system on the horizontal axis. The number of pixel points contained in the target printing object can be determined through the transverse resolution and the longitudinal resolution. In the embodiments of the present application, there is a correspondence relationship between the longitudinal resolution and the lateral resolution, which are preset, and the nozzle droplet volume, and the ink ejection thickness, which are to be determined. When the number of printing points in each sub-area is calculated, the thickness value of the maximum ink jet thickness is substituted into the corresponding relation, the transverse resolution corresponding to the maximum ink jet thickness is calculated, the transverse resolution is used as the transverse resolution of the whole target printing object, and the number of the printing points in each sub-area is determined according to the transverse resolution corresponding to the current maximum ink jet thickness and the size of each sub-area for each sub-area on the target printing object because the longitudinal resolution is known. At this time, the number of printing dots in each sub-area is calculated in accordance with the maximum ink ejection thickness. That is, the number of printing dots in each current sub-area is the number before adjustment (which is recorded as the first number in step 112), and for each sub-area, when the ink ejection thickness of the sub-area is different, the number of printing dots in the sub-area is adjusted according to the ratio of the ink ejection thickness of the sub-area to the maximum ink ejection thickness, specifically, the adjustment is referred to step 112.
In a possible embodiment, when the step 111 of calculating the lateral resolution is executed, the following steps are specifically included:
calculating the reciprocal of the longitudinal resolution, and taking the reciprocal as a first numerical value; calculating the product of the first value and the maximum ink jet thickness, and taking the product as a second value; calculating the ratio of the preset nozzle droplet volume to the second value, and taking the ratio as a third value; and calculating the reciprocal of the third numerical value, and taking the reciprocal as the transverse resolution.
Specifically, the calculation formula is as follows: xyh;
where x is the reciprocal of the lateral resolution xdpi, which is the size of the interval value between each printed dot over the lateral distance, and y is the lateral resolutionThe reciprocal of the rate ydpi, which is the magnitude of the interval value between each printed dot in the longitudinal distance, v is the nozzle droplet volume, h is the ink ejection thickness, when the ink ejection thickness is the maximum ink ejection thickness hmaxWhen h is hmax。
In a possible embodiment, when step 103 is executed to reduce the number of printing points in the sub-area, the method specifically includes the following steps:
step 112, recording the number of printing points in each subarea as a first number; calculating the thickness ratio of the ink jetting thickness of the subarea to the maximum ink jetting thickness; calculating the product of the first quantity and the thickness ratio, and taking the product as a target quantity.
Specifically, for one of the sub-regions, when the ink ejection thickness of the sub-region is smaller than the maximum ink ejection thickness, the target number is obtained according to a calculation formula, and after the target number is obtained, the number of printing dots in the sub-region is reduced to the target number.
The calculation formula is as follows:
wherein b is the target number; h is a total ofmaxMaximum ink jet thickness; a is the number of printing points before reduction; h isnIs the ink jet thickness of the current subdivision, where the subscript n denotes the number of the subdivision, i.e. h1Is the ink-jet thickness of the first sub-division, h2Ink jet thickness of the second subdivision, … …, hnThe ink jet thickness of the nth sub-division.
Example 2, based on the conditions given in example 1, the target number corresponding to the first sub-area is calculated, and then the thickness ratio of the first sub-area is
If the number of print dots before the reduction in the area is a, the number of print dots after the reduction is a
By reducing the number of printing dots in the first sub-area, the thickness of ink ejected is reduced, so that the ink ejection thickness in the first sub-area and the fourth sub-area is different.
Step 113, calculating the difference between the first quantity and the target quantity to take the difference as a second quantity; changing a second number of printed dots in the sub-area to non-printed dots.
Specifically, the first number is the number of print dots before reduction in the sub-area, the target number is the number of print dots after reduction in the sub-area, and the difference between the first number and the target number is the number of print dots that need to be invalidated in the sub-area. In the embodiment of the present application, the printed dots are changed to non-printed dots. It should be noted that, in the process of changing the printing dots to the non-printing dots, the positions of the non-printing dots need to be evenly distributed, so that the positions of the printing dots with the target number in the sub-area are ensured to be evenly distributed, and poor printing effect is prevented.
The method for reducing the number of the printing points is not limited, the method can be realized by controlling the closing condition of the nozzle/the nozzle, and can also be realized by changing the gray value of each sub-area, and the number of the printing points in the sub-area is changed by adjusting the gray value of each sub-area.
Example 3, based on the calculation results of example 2, the first number is a and the target number is
Then it is second
The number of printing dots before reduction in the first sub-area is a, and the number of printing dots after reduction in the first sub-area is a
The number of printing points which need to be invalidated in the first subarea is
If the first sonThe number of printing points corresponding to the area is 1000, and for the first sub-area, the first number a in the first sub-area is 1000, and it is assumed that the thickness ratio of the first sub-area is 1000
The target number is
Then the second number is
The number of print dots that need to be invalidated in the first sub-area is 750.
In a possible implementation, fig. 2 shows a flowchart of a printing method provided in an example of the present application, and as shown in fig. 2, after step 103 is executed, the method further includes the following steps:
Specifically, after step 103 is executed, the number of non-printing dots in each sub-area is already determined, the number and the position of printing dots in each sub-area are determined by evenly distributing the positions of the non-printing dots, and the printing data corresponding to the target printing object is generated according to the positions and the data of the printing dots in each sub-area.
Specifically, the film layer is formed by ink in the target printing object after the printing system finishes jetting ink. After generating the print data through step 201, the printing system prints the target print object based on the print data, thereby forming film layers of different ink ejection thicknesses according to the actual number of print dots in each sub-area.
In a possible embodiment, fig. 3 shows a flowchart of a method for adjusting resolution provided in the examples of the present application, and as shown in fig. 3, when the ink ejection thicknesses of the sub-areas are all the maximum ink ejection thicknesses, the method specifically includes the following steps:
Specifically, when the ink ejection thicknesses of the sub-regions are all the maximum ink ejection thicknesses, the acquired ink ejection thickness of any one sub-region is the maximum ink ejection thickness, and the current lateral resolution and the current longitudinal resolution can be determined by executing step 111, and the values of the lateral resolution and the longitudinal resolution are acquired. In the embodiment of the present application, the longitudinal resolution is preset, the lateral resolution is calculated, and when the maximum ink ejection thickness set by the user for different target print objects changes, the value of the lateral resolution changes without changing the longitudinal resolution. Through this step, the lateral resolution and the longitudinal resolution corresponding to the current target print object are determined.
Specifically, after the transverse resolution and the longitudinal resolution corresponding to the target printing object are obtained in step 301, the difference between the transverse resolution and the longitudinal resolution is calculated, whether the difference between the transverse resolution and the longitudinal resolution is in a preset interval is determined, the transverse resolution and the longitudinal resolution of the printing system are ensured to be similar, and the printing effect is ensured to be better. In actual use, the corresponding sections can be set for the horizontal resolution and the vertical resolution respectively, and the printing system is ensured to print in a specific resolution range.
