The term "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.
For convenience of understanding, a specific flow in an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of a method for processing multi-frame plate-making data in an embodiment of the present invention may include:
s101: and acquiring the size parameters of a plurality of images to be printed and the size parameter of a screen frame to which each image to be printed belongs.
In order to improve the plate making efficiency, in the embodiment of the application, the direct plate making equipment can be controlled to simultaneously produce and process a plurality of screen frames, and the capacity of the direct plate making equipment is utilized to the maximum extent.
In order to achieve the purpose, size parameters of a plurality of images to be printed and size parameters of a screen frame to which each image to be printed belongs need to be acquired, so that a plurality of screen frames are placed on the same breadth for production.
It should be noted that the frame size parameter and the image parameter of each image to be printed may be the same or different, and are not limited specifically.
S102: splicing and combining the screen frames of the images to be printed, so that the screen surfaces of the screen frames of the images to be printed are not crossly arranged in the preset fixed plane area, and recording the position of the screen frame to which each image to be printed belongs in the preset fixed plane area.
After the size parameter of the screen frame to which each image to be printed belongs is obtained, the screen frames of the plurality of images to be printed can be spliced and combined, the specific combination mode is not limited, the screen surfaces of the screen frames of the plurality of images to be printed are all required to be arranged in a preset fixed plane area (namely the same breadth) in a crossed manner, and the position of the screen frame to which each image to be printed belongs in the preset fixed plane area is recorded.
Illustratively, as shown in fig. 2, in the preset fixed plane area S, A, B, C, D, E frames may be spliced and combined, so that the gauze surfaces of the frames of the 5 images to be printed are not arranged crosswise in the preset fixed plane area S. After the splicing combination, a plane coordinate system may be established in the preset fixed plane area S, and the position of each frame may be determined in the plane coordinate system.
It should be noted that the fixed planar area S and the shape of the screen frame may be reasonably set according to the processable breadth of the direct plate-making apparatus, only the rectangular planar area S and the rectangular screen frame are illustrated in fig. 2, and in practical applications, other shapes of the screen frame and the fixed planar area, such as a circular shape, a regular polygon shape, and the like, may also be adopted, and the specific shape is not limited in this embodiment.
S103: and distributing the positions of the images to be printed corresponding to the screen surface areas of the screen frame to which the images to be printed belong.
After the splicing and combination of the screen frames are completed, the positions of the images to be printed which correspond to each other are distributed in the screen surface area of the screen frame to which each image to be printed belongs. Since the position of the screen frame is determined in the plane coordinate system, the position of each image to be printed in the preset fixed plane area is also determined.
It should be noted that each image to be printed can be assigned to any position within the screen area of the associated frame. Preferably, as shown in fig. 2, the A, B, C, D, E frames of the frame corresponding to the image to be printed may be assigned to the central position of the screen side, as shown by the respective black shaded rectangular areas (i.e. the central position) in fig. 2.
S104: and generating a combined image according to the position of each image to be printed so as to carry out multi-screen plate making according to the combined image.
After determining the position of each image to be printed within the preset fixed plane area, a combined image may be generated according to the position of each image to be printed. And the position of each image to be printed in the combined image is consistent with the position relation of each image to be printed in the preset fixed plane area. For example, a large-area template such as a preset fixed plane area is newly created, and then a combined image is generated in the template according to the position relation position of each image to be printed in the preset fixed plane area.
Illustratively, taking the stitching combination shown in fig. 2 as an example, a combined image generated from a plurality of images to be printed is shown in fig. 3.
Plate making process can be carried out by combining the direct plate making equipment in the related art based on the combined image. Specifically, the combined image may be rasterized, that is, page information described by the page description language is rasterized into data information in the form of a pixel dot matrix image, where the data information at least includes distribution information of pixel exposure point positions. The pixel exposure point refers to any one of two types of pixel points contained in the binary dot matrix image. And then, according to the position distribution information of the pixel exposure points, controlling emergent light of the direct plate-making equipment to expose the photosensitive or thermosensitive coating on the preset fixed plane area, so that the pixel exposure point positions are exposed, and the non-pixel exposure point positions are not exposed, thereby forming latent images of respective images to be printed on the photosensitive or thermosensitive coatings of the plurality of frames. The emergent light of the direct plate making equipment is light modulated by the DMD digital micromirror device, and can also be light emitted by a laser, and the specific point is not limited here.
As can be seen from the disclosure of the above embodiments, in the embodiments of the present invention, the screen frames of the images to be printed are spliced and combined, so that the gauze surfaces of the screen frames of the images to be printed are not arranged in the preset fixed plane area in a crossed manner, and the position of the screen frame to which each image to be printed belongs in the preset fixed plane area is recorded; then distributing the positions of the images to be printed corresponding to each other in the screen surface area of the screen frame to which each image to be printed belongs; the combined image is generated according to the position of each image to be printed, the multi-screen frame plate making process is carried out based on the combined image and the existing direct plate making equipment, the plate making can be carried out on a plurality of screen frames in one-time plate making process, and the screen printing plate making efficiency is greatly improved.

the splicing module is used for splicing and combining the screen frames of the images to be printed, so that the screen surfaces of the screen frames of the images to be printed are not arranged in a preset fixed plane area in a crossed manner, and the position of the screen frame to which each image to be printed belongs in the preset fixed plane area is recorded;
the configuration module is used for distributing the positions of the images to be printed in the screen surface area of the screen frame to which each image to be printed belongs;
and the combination module generates a combined image according to the position of each image to be printed, so that the position of each image to be printed in the combined image is consistent with the position relation of each image to be printed in the preset fixed plane area.
8. The system of claim 7, further comprising:
and the processing module is used for rasterizing the combined image to obtain the position distribution information of the pixel exposure points.
9. A direct-to-plate apparatus comprising a processor for implementing a method as claimed in any one of claims 1 to 4 when executing a computer program stored in a memory.
10. A computer-readable storage medium having stored thereon a computer program, characterized in that: the computer program, when executed by a processor, implements the method of any one of claims 1 to 4.
