This study presents statistical evaluation of the dot area and line width on thermally developed CtP flexo printingplates using image analysis software PerfectEye v4.03. The aim of the study was to determine whether the dot area and line width when different processing parameters are applied (different main exposure time and different numberof rotations of developing drum during developing process) were statistically different from each other or not. Im-age analysis of dots and lines were performed with a VipTronic Vipdens measuring device using CCD camera and a PerfectEye image analysis software. The shape data, dot area and line width were compared by applying one way ANOVA (analysis of variance) method followed by post hoc Tukey’s test using the software SPSS (Statistical Pack-age for Social Science) and independent sample T-test with a 0.05 significance level. Statistical analysis revealedthat the difference between the dot area and line width for different processing conditions are significant with a 95% confidence level.
