Systems and methods for printing of removable and permanent images on an object

A method for printing a plurality of images on an object, the method comprising, by a processor:

• receiving a digital file comprising a plurality of images to be printed on an object, wherein the plurality of images comprise one or more removable images and one or more permanent images;
• for each of the plurality of images:
• determine whether that image is a removable image or a permanent image,
• identify, based on the determination, at least one layer to be used for printing that image in addition to a marking material layer, wherein the at least one layer comprises a pre-coat layer applied under the marking material layer or a post-coat layer applied over the marking material layer,
• determine a composition of the marking material layer, and
• determine a composition of the at least one layer, wherein if that image is determined to be a removable image, determining the composition of the at least one layer comprises:
• determining the composition to improve removability of the marking material layer from a surface of the object, and
• determining that the at least one layer is a pre-coat layer whose composition is determined based on at least one of the following:
• a pre-coat layer that has a thermal expansion coefficient that is different from that of the object surface,
• a pre-coat layer that has a solubility coefficient that makes it soluble in one or more solvents such that the pre-coat layer and the marking material layer applied over it may be removed by subjecting the object to the one or more solvents,
• a pre-coat layer that is soluble in one or more solvents at a pre-determined pH such that the pre-coat layer and the marking material layer applied over it may be removed by subjecting the object to the one or more solvents at the pre-determined pH;
• or
• a pre-coat layer that forms a substrate under the marking material layer such that that image can be removed by peeling off the substrate;
• operating a plurality of print heads to eject marking material based on the determined composition of the marking material layer for each of the plurality of images;
• and
• operating a plurality of layer applicators to apply the identified at least one layer based on the determined composition of the at least one layer for each of the plurality of images by applying the marking material layer over the at least one layer if it is a pre-coat layer and under the at least one layer if it is a post-coat layer.
