An offset lithograph print is created by creating a plate with the image to be printed.  Color images are produced using a four-color separation process, in which four different plates are made for the cyan, magenta, yellow, and black inks; when the plates are printed, the colors blend together visually, creating a color image. This printing technique takes advantage of the fact that oil and water do not mix.  The plate is brushed with rollers coated in water, and then with rollers covered in ink.  The ink is attracted to the parts of the plate which were exposed earlier, while the water keeps the unexposed portions clear so that they do not smear or transfer ink.  Then, the plate transfers the ink to a rubber roller know as a "blanket," and the blanket rolls across the paper; typically the paper is fed between the blanket and another roller to ensure that the image stays crisp.Our lithograph prints are printed on acid-free paper. The majority of our prints are printed on 95# paper with a dull aqueous finish.
