Application of Near Infrared Spectroscopy in the Analysis of Printing Color Detection
For the fast and exact detection of printing color,we combine the near infrared (NIR) spectroscopy technique with partial least square (PLS) to build the detection model of printing color.Applying the 144 samples of spectral curve which obtained by the near infrared spectroscopy randomly separated into training set and test set,and base on the 120 training set data to establish the prediction model of printing color by PLS,then this model is employed for predicting the color of the 24 test set.The RMSEC of the 24 blocks color parameters L*,a*,b*,E are 0.73,2.26,3.03 and 1.09 respectively; The RMSEP are 0.97,2.77,3.57 and 1.34 respectively.Those results tell that the NIR spectrum and blocks color parameters L*,a*,b*,E could accurately establish a quantitative regression model,applying such model also can accurately predict unknown samples,and the results approximate to the original reference data.The use of near infrared spectroscopy to detect the printed matter nondestructively is feasible,and lays the foundation for the further analysis and establishment of printing chroma model.
