    Abstract: The present disclosure relates to a process for selectively printing an image onto a substrate. The process comprises electrophotographically printing a first ink composition onto selected areas of a substrate. The process also comprises applying a primer over at least the unprinted areas of the substrate. A second ink composition is printed onto the primerand the first ink compositionis removedfrom the selected areas of the substrate. The first ink composition is a transparent electrophotographic ink composition.
