Method for achieving oil painting three-dimensional duplication through ultraviolet-light-emitting diode (UV-LED) ink-jet printer

Abstract

The invention discloses a method for achieving oil painting three-dimensional duplication through an ultraviolet-light-emitting diode (UV-LED) ink-jet printer. The method comprises the following steps that (1) colored image information of an oil painting is obtained through two-dimensional non-contact scanning equipment; (2) pigment height information of the oil painting is obtained through three-dimensional scanning equipment, and a surface configuration three-dimensional model of the oil painting is established; (3) the number of layers of printing is determined according to the Z-axis height of the model, and the number of the layers is obtained by dividing the maximum value of the Z-axis by the average thickness of a single layer of white ultraviolet (UV) printing ink; (4) the cross section of each layer is extracted, and the cross sections of the layers are introduced into the UV printer to be printed after being subjected to vectorization treatment; (5) stacking printing is conducted through the white UV printing ink according to layer data, and a white three-dimensional oil painting entity is obtained; and (6) colored images are printed on the white three-dimensional oil painting entity, and a three-dimensional oil painting duplicate is formed. By means of the method, the concave-convex undulating characteristics of pigment on the surface of an oil painting original manuscript can be reproduced veritably, the three-dimensional impression of a real oil painting is achieved, the deficiency that the three-dimensional duplication of the oil painting cannot be achieved through an ordinary paint spraying and printing method is remedied, and the requirements for high-fidelity oil painting duplication can be met.

Description

technical field [0001] The invention relates to a method for duplicating oil paintings, in particular to a method for realizing three-dimensional duplication of oil paintings with a UV-LED inkjet printer. Background technique [0002] With the continuous improvement of people's aesthetic level, everyone has higher and higher requirements for the quality of oil paintings. However, it is difficult for ordinary consumers to obtain the originals of world famous paintings, so high-simulation reproductions of oil paintings are more and more popular among people. [0003] At present, the relevant patents related to the high-simulation reproduction of oil paintings are: (1) "Method for making simulated oil paintings on fabrics by screen printing" (1997.7), publication number: CN1155479A, this patent can produce a certain three-dimensional undulation of the oil painting surface, but cannot Duplicate the same pigment height as the original painting; (2) "A New Process for Duplicating ...

[0003] At present, the relevant patents related to the high-simulation reproduction of oil paintings are: (1) "Method for making simulated oil paintings on fabrics by screen printing" (1997.7), publication number: CN1155479A, this patent can produce a certain three-dimensional undulation of the oil painting surface, but cannot Duplicate the same pigment height as the original painting; (2) "A New Process for Duplicating Oil Painting" (1999.12), publication number CN1236711A, this patent uses a two-dimensional scanner to obtain oil painting image information and prints it out with an inkjet printer, which cannot realize the surface of oil painting Replication of ups and downs; (3) "A Relief Oil Painting and Its Making Method" (2003.8), Publication No. CN1436671A, this patent uses an adhesive to paste on the oil canvas, and then paints on its surface, its three-dimensional Strong sense, but the production efficiency is low, and it is difficult to copy the original oil painting

(4) "THREE-DIMENSIONAFFSETPRINTINGMETHODFOROILPAINTINGPRINTING" (2012.8), International Publication No. WO2012 / 113141A1, this patent first uses silk screen printing to make the concave and convex surface of the oil painting, and then uses the method of offset printing to obtain the oil painting with a concave and convex feeling, but because there is no accurate The surface fluctuation data of the original manuscript, so the surface fluctuation of the copied oil painting must be inaccurate; (5) "A high-simulation oil painting material printing process" (2012.12), publication number CN103103814A, this patent mainly prepares oil painting materials, making The printed oil painting has the color and light of the original painting and the overall look and feel, but it also lacks the replication of the unevenness of the pigment; (6) "A Method for Making Oil Painting with a Stereoscopic Surface" (2013.6), Publication No. CN103332095A, this patent is mainly made by pasting three-dimensional rope or metal objects to achieve the three-dimensional look and feel of the oil painting, but for the purpose of oil painting reproduction, high-fidelity reproduction of the original manuscript cannot be achieved; (7) "A method for oil painting reproduction" (2014.5), publication number CN103770488A, the patent passed the Thickness meter is used to measure the uneven height of the original paint, and it is copied by screen printing and offset printing. This method can roughly replicate the original paint height. The thickness of a certain point, and the replication method is time-consuming and costly, and is not suitable for small-batch replication

In addition, if hand-painted oil paintings are copied, there are many problems. The process takes a long time and the efficiency is low. It is difficult to accurately copy the color of the paint and the ups and downs of the strokes. limits
