【摘要】：目的打印输出技术是目前国内外图像复制领域的主流技术。打印机特征化旨在建立打印机输入控制值与输出色彩信息值之间的对应关系,保证打印输出图像各像素色彩值的准确性。基于可见光谱的打印机特性化过程,以图像光谱信息作为打印机特性化过程中的色彩控制依据,可避免基于色度的打印输出过程所固有的同色异谱问题,实现图像色彩复制领域最高级别的无条件颜色匹配。在广泛文献调研的基础上,本文回顾了打印机光谱特性化方法各部分研究的发展历程,分析介绍了该领域主要研究内容及其研究现状,对打印机光谱特性化方法流程进行了较为全面的综述。方法以Yule-Nielsen修正的光谱Neugebauer模型(YNSN模型)为典型代表,从打印机墨量限制方法、正向光谱预测模型、反向光谱分色模型以及色彩匹配评价度量4个方面,对目前基于可见光谱的打印机特性化方法研究情况进行了总结与归纳,并结合现有研究存在的问题对未来研究发展趋势进行了展望。结果综合近几年该领域研究发展情况,认为目前打印机光谱特性化方法研究在墨量限制算法合理性、正反向建模精度等方面已经取得了较为理想的结果。然而,尽管已有20多年的广泛研究,鉴于光谱数据的高维性以及具体应用场景的多样性,导致准确而高效的实现光谱打印机特性化仍然是一个极具难度的问题,特别在建模效率提高、模型适用性增强、模型物理意义提升以及评价度量综合性能优化等方面,目前研究仍存在较大的研究发展空间。结论打印机光谱特性化是实现图像色彩信息高保真打印复制的必要手段,其今后将继续在图像复制领域起到非常关键作用。然而,由于基于光谱的打印机特性化过程涉及光谱学及色度学理论、半色调呈色理论、最优化计算理论、人眼视觉机理、数字加网技术等多种理论与技术,故其研究具有一定的难度与挑战性。本文对打印机光谱特性化方法研究现状进行了较为深入的介绍与分析,意在使国内同行对该领域有一个较为全面的了解,以期引起更多研究者对该领域的关注。由于篇幅所限,许多问题未及深究。
[Abstract]:Objective Printing and output technology is the main technology in the field of image reproduction at home and abroad.The purpose of printer characterization is to establish a corresponding relationship between the printer input control value and the output color information value, and to ensure the accuracy of each pixel color value of the print output image.The printer characteristic process based on visible spectrum and the color control basis of printer characteristic process based on image spectrum information can avoid the problem of the same color spectrum inherent in the printing and output process based on chroma.The highest level of unconditional color matching in the field of image color reproduction is realized.On the basis of extensive literature research, this paper reviews the development of various parts of the research on spectral characterization of printers, analyzes and introduces the main research contents and research status in this field.The process of spectral characterization of printers is reviewed in this paper.Methods the spectral Neugebauer model modified by Yule-Nielsen was used as a typical example. The method of printer ink limitation, the forward spectral prediction model, the reverse spectral color separation model and the evaluation of color matching were used.In this paper, the current research situation of printer characterization method based on visible spectrum is summarized and summarized, and the future research trend is prospected combined with the existing problems.Results based on the research and development in this field in recent years, it is considered that the current spectral characterization method of printer has achieved satisfactory results in the aspects of ink limitation algorithm rationality, forward and backward modeling accuracy, and so on.However, despite more than 20 years of extensive research, in view of the high dimension of spectral data and the diversity of specific application scenarios, it is still a very difficult problem to achieve the accurate and efficient implementation of spectral printer characterization.Especially in the aspects of improving the efficiency of modeling, enhancing the applicability of the model, enhancing the physical meaning of the model and optimizing the comprehensive performance of evaluation metrics, there is still a great space for research and development.Conclusion Spectral characterization of printer is a necessary means to realize high fidelity printing reproduction of image color information, and it will continue to play a very important role in the field of image reproduction in the future.However, the process of printer characterization based on spectrum involves many theories and technologies, such as spectroscopy and chromaticity theory, halftone color theory, optimization calculation theory, human visual mechanism, digital screen technology, etc.Therefore, its research is difficult and challenging.In this paper, the present situation of the research on the spectral characterization of printers is introduced and analyzed in order to make the domestic counterparts have a more comprehensive understanding of the field, in order to attract more researchers to pay attention to the field.Due to space constraints, many questions have not been studied in depth.
