Display Performance

In recent years, screen soft proofing has matured with the development of color management and display technology, and it has become the direction of printing development and the key of promotion. This article aimed at raising a testing scheme of display performance and adjusting scheme of corresponding display parameters, on this account to test the professional display’s performance, adjust display parameters and make color management. At the same time with reflecting the actual situation of display, a stable and accurate color reproduction environment was provided for screen soft proofing. After that, evaluations were carried out to evaluate printing quality of screen soft proofing on the condition that display’s performance was good, consequently the differences between proofing effects and final printing were studied. The result shows that this testing scheme of display performance can reflect the truth of display which is tested in this paper, the display after adjusted and color management according to this scheme shows good effect in the ability of screen analog proofing original, it can approach the requirements of the printing proofing.

Color Rendering

The accuracy of color appearance of displayed image on a liquid crystal display (LCD) is the fundamental to guarantee good results in the soft proofing and cross-media color reproduction. Since the color rendering mechanism of LCDs is different from cathode-ray tube (CRT) displays, the traditional color calibration method cannot turn a very good result. In this paper, a LCD color calibration model based on gamut-division algorithm is proposed using spline method through the analysis of its color rendering mechanism. The monitor 3D gamut is firstly divided along the axis of L* in CIELAB color space according to the hue angle, and then an optimal color calibration matrix of the sub-gamut is computed with mathematical method. The experimental results show that the average color difference, the maximum color difference and hue shift are reduced compared with the traditional method.

Soft Proofing

In this thesis, an adaptive mechanism for controlling the illumination is combined with a closed loop technique and the use of High Dynamic range (HDR) to generate a black box model that can simulate the hard proof of a given digital image. An adaptive Artificial Neural Network (ANN) was used to create the black box model, using the camera as a measuring device. The non-uniformity of the illumination in the viewing booth is typically a barrier in creating such a black box model since color appearance varies with location in the viewing booth. This issue was addressed in this thesis by compensation for viewing booth illumination using an inexpensive camera and a Liquid Crystal Display (LCD) projector. HDR was found to give a favourable representation that is more indicative of the image perceived by the operator, and was used as the basis for mapping the original image to the soft proof. A proof of concept was also developed to highlight the utility of the LCD projector based approach in providing a more broad range of varying intensity color illuminants (thus environments) under which a proof may be not only viewed, but modeled through the closed loop process. In this sense, a system has been developed to generate and provide custom soft proofs that can extend the functionality of the standard viewing booth. The proposed technique will open the doors to new automated systems that can be very beneficial to the printing industry.
