Method for providing a natural colour and optical depth to a dental object, wherein the dental object has a substantially identical colour and optical properties to nearby/adjacent dental objects or to a reference dental object, the method comprising the steps: - providing a patient specific framework of the dental object based on a previous dental object or a nearby/adjacent/chosen natural tooth or a reference dental object, - taking an object colour picture or 3d colour object scan of one or more nearby/adjacent/chosen natural tooth or reference dental object, and uploading the digital picture elements of the object colour picture or of the 3d colour object scan into a computing device, - optionally calibrating and/or adjusting the digital picture elements of the uploaded object colour picture or 3d colour object scan with regard to the image size and/or the resolution, - defining the target object colour picture in a computing device based on the object colour picture or 3d colour object scan, - selecting an enamel material and (pre)determining the thickness profile of the enamel material to be applied on the framework, - correcting in a computing device of the digital picture elements of the target object colour picture for the thickness profile of the enamel material to be applied at the position of the digital picture elements by means of a formula expressing the relationship between colour measurements over a known enamel layer thickness, and providing a print colour picture of the corrected digital picture elements of the target object colour picture, - printing the print colour picture comprising the corrected digital picture elements as a print layer on the framework, - applying the enamel material in the predetermined profile-thickness upon the print layer upon the framework. - providing a patient specific framework of the dental object based on a previous dental object or a nearby/adjacent/chosen natural tooth or a reference dental object, - taking an object colour picture or 3d colour object scan of one or more nearby/adjacent/chosen natural tooth or reference dental object, and uploading the digital picture elements of the object colour picture or of the 3d colour object scan into a computing device, - optionally calibrating and/or adjusting the digital picture elements of the uploaded object colour picture or 3d colour object scan with regard to the image size and/or the resolution, - defining the target object colour picture in a computing device based on the object colour picture or 3d colour object scan, - selecting an enamel material and (pre)determining the thickness profile of the enamel material to be applied on the framework, - correcting in a computing device of the digital picture elements of the target object colour picture for the thickness profile of the enamel material to be applied at the position of the digital picture elements by means of a formula expressing the relationship between colour measurements over a known enamel layer thickness, and providing a print colour picture of the corrected digital picture elements of the target object colour picture, - printing the print colour picture comprising the corrected digital picture elements as a print layer on the framework, - applying the enamel material in the predetermined profile-thickness upon the print layer upon the framework. <EOS>
