Problems solved by technology

[0003] The existing 2.5D image printing technology requires manual matting to process the image, the printed image layer is limited, the image cannot be restored well, and the image effect is distorted
In addition, the existing 2.5D image printing technology is flat printing, which cannot reproduce original paintings or files with a concave and convex feeling.

Embodiment Construction

[0035] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will specifically illustrate the 2.5D image printing method of the present invention in conjunction with the accompanying drawings.

[0036] In the present embodiment, under the 64-bit Window 7 operating system, a scanned image of an oil painting (the pixel is 2486 × 2486, the resolution is 244.206dpi, and the image size is 25.86cm × 25.86cm) is used as the input manuscript, and the height information layer Extracted by MATLAB 2013b software programming. The printer is an OCE Arizona 460 GT UV printer (the maximum printing format is 2500mm×1300mm, and the maximum thickness of the overprint ink layer is 5cm), and the printing material is Poster Grade Paper.

[0037] figure 1 It is a schematic flow chart of the 2.5D image printing method of this embodiment.

[0038] Such as figure 1 As shown, the 2.5D image printing method in...

Abstract

The method provides a 2.5D image printing method capable of accurately restoring and printing an original manuscript. Significant information in the original manuscript is extracted in a multi-level manner in a transformation domain, and height information in different tone positions of the original manuscript is simulated and printed out in multi-level extraction and overprinting modes, so that the 2.5D image printing method has the advantages of automatic extraction, rich levels, high self-adaption, high restorability and the like. Compared with an existing 2.5D printing method, the 2.5D image printing method has the advantages that the height information in the original manuscript can be automatically simulated and extracted through a computer, a tedious printing pre-processing process is avoided, further, restorability for tone levels is higher, rich information in the original manuscript can be accurately reproduced, and the 2.5D image printing method has certain artistic value in the field of printing reproduction of a few special original manuscripts.

Description

technical field [0001] The invention belongs to the field of new digital printing technologies, in particular to a 2.5D image printing method for improving the visual effect of printed drafts. Background technique [0002] Digital printing is a technology that uses the pre-press system to directly transmit digital graphic information to the printing machine for printing. It has developed extremely rapidly with the advantages of strong personalization, fast delivery of on-demand printing, and resource saving. With the continuous emergence of various new printing technologies, many personalized printing methods have gradually come out. [0003] The existing 2.5D image printing technology requires manual matting to process the image, and the printed image has limited layers, which cannot restore the image well, and the image effect is distorted. In addition, the existing 2.5D image printing technologies are all flat printing, which cannot reproduce original paintings or docume...
