Abstract

The present invention relates to a method for printing an image on a substrate, preferably glass, ceramics or glass ceramics,comprising the steps of:- Providing image template data for an image to be printed by an image providing computing entity,- Analyzing said image template data by identifying image components of said image,- Providing a substrate for printing said image thereon by a substrate feeding entity,- Providing an ink for printing said image by an ink supply entity,- Printing said image using said image template data on said substrate with said ink using a printing procedure, preferably Inkjet-Printing-procedure, based on printing parameters with a printer operating using printer configuration parameters,- Capturing said printed image on said substrate by one or more image capturing entities, and providing captured image data of said captured image,- Analyzing said captured image data, using an analyzing procedure by an analysis computing entity, said analyzing procedure comprising∘ Providing definition parameters for defining at least one region of interest, ROI,∘ Determining said at least one ROI, within the captured image data based on the provided definition parameters,∘ Identifying in said at least one ROI at least one image component, and∘ Determining for said at least one ROI at least one image metric,∘ Relating said at least one image metric to said at least one image component,- Relating said identified at least one image component in said image template data to said at least one identified image component of said at least one ROI related with said at least one image metric,- Selecting one or more printer configuration parameters and/or printing parameters for correction, preferably based on at least one image metric and/or at least one image component,- Computing at least one actual correction parameter for said selected printer configuration parameters and/or said selected printing parameters based on an optimization computing procedure using said at one image metric, wherein said at least one actual correction parameter being image component specific.
