Research Of Printing Image Color Halftoning Technology

With the development of the computer technology and printing technology, there is a growing pursuit of high-quality printing products. The key to the print quality of color is the reproduction of color technology. How to control the color printing process is essential to ensure the consistency of color. The color management can ensure that the visual effects of the final color is in line with the original color. Chromatic aberration of Color printing is in the range of 6. This article use the least squares halftoning model to test the image quality and color-matching, with the result we can draw the effects, which has a certain degree of scientific and novelty. Embedded the test modules in the color management module, which is in the detection of the printing quality . It can timely feedback the carry out a more reasonable and result to adjust the printing parameters to scientific printing. The effect of color-matching process is particularly important on the color transfer, least squares model can test the color gamut with scientific and rational conversion detection. Use Java program and algorithm design to acurately calculate the color value of halftoning image pixel.Least squares model is the classic model to halftone color images, which has great significance to graphic reproduction technology.
