Description

Digital printing system and method for generating 3D preview image

technical field

The invention relates to the technical field of digital printing, in particular to a digital printing system and method for generating 3D preview images.

Background technique

In current digital printing, the printing result is usually previewed by generating a preview image or printing a test sample. The way of generating the preview image to display the preview image of each arranged page can basically meet the requirement of a relatively simple layout (for example, only one small page is included on a layout). For complex layouts, for example, when there are two or more small pages on one layout, the user needs to compare the original file with the selected binding method to manually determine whether the output result is correct, and generally only when the user is completely clear In the case of the small page distribution on each layout, it is possible to correctly determine whether the output result is correct. In addition, the user generally needs to check each page and judge whether it is correct, the workload is quite large, and the probability of error is also high. As for the way of printing test samples, there is a bigger problem. Users can only print part of the test samples, it is impossible to output all of them, let alone guarantee that the output results are completely correct.

In the Chinese patent application "image forming device and printing preview image forming method" with application number 200810000809.9, a preview method and device capable of displaying double-sided printing results are proposed. In this apparatus, the page number of a page image formed on the front side of the recording material at the time of double-sided printing is input through the page specific designation part on the operation interface, and a print preview image including the folded image is displayed on the preview output part, The flipped image includes three areas, the first area displays the image portion on which the specified page image is formed, the second area displays the image portion extracted from the next page image of the specified page image, and the third area The area displays the portion of the image extracted from the next two page images of the specified page image. Through this preview method and device, it is easy to intuitively grasp the page order and the relationship between the front and back of each page image. However, this method statically simulates the preview effect when outputting the front and back sides in a folded manner, and needs to input page numbers page by page, and cannot dynamically display the preview effect, and cannot preview and display according to the binding method selected by the user.

For example, a magazine has 8 pages and is bound by saddle stitching. At this time, pages 1 and 8 are on a large layout, pages 2 and 7 are on a large layout, pages 3 and 6 are on a large layout, and pages 4 and 5 are on a large layout. on a large page. According to the commonly used preview image preview method, the above four large layouts are statically presented to the user, and it is often difficult for the user to distinguish whether the printing effect is correct, and according to the preview method disclosed in the above patent application, the order of each page can only be displayed statically It is related to the front and back, but cannot be dynamically previewed according to the binding method selected by the user.

Therefore, since the existing printing result preview method cannot dynamically display the final printing effect simply and intuitively, it cannot meet the increasingly complex printing requirements in the current digital printing market.
