Problems solved by technology

At the same time, although excessive ink volume limitation can avoid the problem of ink volume exceeding the limit, it will cause the loss of printing color gamut, thereby affecting the final color effect of the printout. The impact is particularly large
For the above problems, the academic and industrial circles have not yet proposed a method to limit the amount of ink from the perspective of maximizing the color gamut

Embodiment Construction

[0024] When the technical solution of the present invention is specifically implemented, it can be automatically operated by those skilled in the art by using computer software technology. In conjunction with the accompanying drawings, the specific description of the embodiments of the present invention is provided as follows.

[0025] like figure 1 The illustrated embodiment provides an ink volume limitation method for maximizing the color gamut of inkjet printing, which can overcome the ink volume overrun problem and at the same time realize the printing output effect of maximizing the color gamut, mainly including the following steps:

[0026] 1) Judgment pattern for the overrun of the input ink volume, the pixel size and specific shape of the pattern can be preset by those skilled in the art. In order to ensure the output accuracy of 600DPI and above, the embodiment sets the pattern as a square image with a side length of 30-50 pixels, defines the middle pixel and the set...

Abstract

The invention discloses an ink-quantity limiting method for realizing maximization of ink-jet printing color gamut. According to the method, the problem of ink-quantity over-limit of ink-jet printing is solved while the maximization of printing output color gamut is realized. The method is suitable for the field of high-fidelity ink-jet copying. The method comprises the following steps: judging Neugebauer primary color scale of a pattern according to the condition of printing with specific ink-quantity over-limit and confirming the maximal color gamut of the color space of the control value of ink-jet printer equipment; calculating the volume of the color gamut through a convex hull algorithm; and taking the coverage rate of the maximal volume of the color gamut as a criterion, correcting a correlation coefficient in a nonlinear interpolation algorithm through circulating calculation, and finally confirming an ink-quantity limiting algorithm. According to the method, the problem of print waste caused by the ink-quantity over-limit is solved while the ink-jet copying quality is increased at the aspect of color reproduction, the implementation is convenient, and the method has higher applicability in the field of high-fidelity color copying.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing color reproduction, and in particular relates to an ink quantity limitation method for maximizing the color gamut of inkjet printing based on multi-dimensional nonlinear interpolation. Background technique [0002] Inkjet printing refers to the process in which the printer sprays pigment ink droplets onto the printing medium through the printing nozzle to achieve color reproduction. In recent years, with the improvement of equipment precision and the quality of consumables, the advantages of this kind of color reproduction technology, such as rich layers, clear details, wide color gamut, and various substrates, have gradually emerged. It has become a major mainstream in the field of image reproduction at home and abroad. Affected by the properties of the paper and ink itself, there is a specific upper limit for the maximum amount of ink that can be carried by the printing paper. When the a...
