Abstract: A system and method of printing articles including removable concealing areas. To efficiently produce a printed article with concealed areas of high print quality, an inkjet printing process, preferably drop on demand (DOD) inkjet printing, is used to create a raised printed area. To adequately conceal printed areas, a clear doming material is applied over the printed area before concealing. The clear doming material covers or fills any raised printed areas to create a level surface for subsequent application of a concealing layer. In one embodiment, a hot foil stamping method is used to produce a scratch-off concealing layer. Upon scratching or abrading by the end consumer, the concealing layer is removed to reveal the printed area.
