An apparatus for flexographic printing for use both with inks/varnishes that are not compatible with hydroxyl groups and with inks/varnishes that are compatible with hydroxyl groups. The apparatus includes pumps, viscometers, viscosity adjusters and washing systems that are dedicated to each of the two types of solutions. In addition, the apparatus may be used for preparing a printed article by pattern applying more than one type of coating onto an article substrate. Unique patterns are laser engraved onto non-polar polymeric flexographic rollers/plates that may be impregnated with silicone, to preferably each coat different portions of the article substrate surface.
