| Popis: | 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 areaand 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. Imageanalysis of dots and lines were performed with a VipTronic Vipdens measuring device using CCD camera anda PerfectEye image analysis software. The shape data, dot area and line width were compared by applying one wayANOVA (analysis of variance) method followed by post hoc Tukey’s test using the software SPSS (Statistical Packagefor 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. |
