Analysis of Densitometric and Colorimetric Evaluation Methods for Ink Trapping

ZHU Yuan-hong(Shenzhen Polytechnic,Shenzhen 518055,China)  
Three evaluation methods currently used for ink trapping were analyzed with densitometric measurement.Three evaluation methods for trapping with colorimetric measurement were put forward.The different evaluation methods for trapping were analyzed and compared through experiment.It was concluded that densitometric evaluation methods for trapping have some shortcomings;the accuracy of colorimetric values predicted with Neugebauer equations is not accurate enough;the colorimetric and chromatic evaluation methods for trapping give lots of advantages and can be used completely for practical test of printing products.
