Study on the Applied Performance of Color Inks
In order that a better analysis and evaluation of the color performance of developed color inks according to the printing requirements could be obtained,every ink will get abundant levels of ink supply amount made by double-channel control method.The max density obtained by the above method represents the color strength of inks.Then Color Management System is applied to building color gamut of matching process inks,and the color gamut represents the replicable color scope in practice.First,color strength of inks was identified by the following methods.Every ink was put respectively in two ink channels of the color printer and the total values of these two channels were applied to controlling the output,obtaining the wedge diagram of the multilevel output of ink supply amount.In the diagram,the max ink supply amount was large enough and the max density could represent the color strength.Because every ink needs a suitable range of the max density and needs to match the others well in practice.Referring to the standard of offset printing,a suitable density value for a certain ink was chose as its max ink supply amount.Second,within the range of the max ink supply amount,the data set of color patch in the characterization software of Color Management System was used to control ink supply amounts.The color patch was overprinted in the color sequences of Y,M,C and K,and ICC Profile was made according to the making process of standard Profile.Color gamut of the inks could be obtained from the Profile by using self-developed computing equipment and be compared with standard printing process.The result shows that the method used in the experiments is feasible and effective.In addition,the inks in the experiments have a large enough color strength and a color gamut satisfying the practical requirements of the color performance of inks in the printing industry.
