Print inspection apparatus for optically inspecting a print image of a print object, the print object being printed on a substrate, the print object being associated with a target print object, comprising: an image camera configured to optically record the print object on the substrate to obtain a print object image; and a processor configured to segment the print object image based on the target print object into image regions, to determine a first coloration level for a first image region, wherein the first coloration level indicates a proportion of a color within the first image region, to determine a second coloration level for a second image region, wherein the second coloration level indicates a portion of a color within the second image region, to determine a third coloration level for a third image region, wherein the third coloration level indicates a proportion of a color within the third image region, to determine an under-coloration measure for the print object using the first coloration level, the second coloration level and the third coloration level, wherein the under-coloration measure represents a likelihood of under-coloration of the print object on the substrate, to determine an over-coloration measure for the print object using the first coloration level, the second coloration level and the third coloration level, wherein the over-coloration measure represents a likelihood of over-coloration of the print object on the substrate, to determine a quotient between the under-coloration measure and the over-coloration measure to obtain a print quality indicator, and to compare the print quality indicator with a predetermined threshold to optically inspect the print object image of the print object. an image camera configured to optically record the print object on the substrate to obtain a print object image; and a processor configured to segment the print object image based on the target print object into image regions, to determine a first coloration level for a first image region, wherein the first coloration level indicates a proportion of a color within the first image region, to determine a second coloration level for a second image region, wherein the second coloration level indicates a portion of a color within the second image region, to determine a third coloration level for a third image region, wherein the third coloration level indicates a proportion of a color within the third image region, to determine an under-coloration measure for the print object using the first coloration level, the second coloration level and the third coloration level, wherein the under-coloration measure represents a likelihood of under-coloration of the print object on the substrate, to determine an over-coloration measure for the print object using the first coloration level, the second coloration level and the third coloration level, wherein the over-coloration measure represents a likelihood of over-coloration of the print object on the substrate, to determine a quotient between the under-coloration measure and the over-coloration measure to obtain a print quality indicator, and to compare the print quality indicator with a predetermined threshold to optically inspect the print object image of the print object. <EOS>
