Standard tone reproduction curve and electr onic color scanning working curve are derived from human eye's visual characteristic, Munsell equation and color reproduction in combination with practical process line and conditions.
This paper mainly discusses a chromatics equation which is very important in the conversion from color space to printing ink space in color industry and color reproduction industry-the Neugebauer Equations.
A method of choosing ideal subtractive primary colors is presented according to the color reproduction request. The optimum spectral reflectance curves and chromaticity characteristics for ideal subtractive primary colors are discussed.
Under the same printing conditions,the printing experiment was made using flexographic press and the profile document of flexography was produced,then the curves of dot gain,tones reproduction in flexography and the characters of color reproduction were established.
On the basis of analyzing the method of producing traditional printer sample sets, an improved method to produce printer sample sets is presented , which enlarges the printer gamut availably and improve the color reproduction ability of the printer.
