Method for determination of color reproduction of print imprints produced by offset method of printing includes measurement of color coordinates of billets of control scales and calculation of color deflection. According to the method measurement of Lab coordinates of billets is performed by spectro-photometer that is connected to personal computer, results of series of measurements are stored as text file, calculation of characteristic of color deflection are carried out by formula, with implementation of statistical processing of series of measurements, one compares confidence interval obtained for characteristic of color reproduction for each of bullets to standard values and makes conclusion on quality of color reproduction of the imprint. |
