ABSTRACT:
A method of color printing on packaging containers using transparent colors is described. The method is limited to the use of no more than two of the primary process colors. For many images primary process colors are not needed at all. Preferably, only two transparent inks will be used. In some cases an opaque ink may be applied first as a masking image underlying a part or all of the transparent ink overprint. In other cases the opaque ink may be applied last as a masking print over part of the image. The method can be used on any substrate color but it is particularly useful on dyed papers or unbleached kraft brownboard. While color reproduction is not totally accurate, nor is this expected in a colorimetric sense, surprisingly attractive and realistic images generally faithful to the original are attainable.
