Lincoln in Dalivision Continuous Tone Print, Gallery Poster Salvador Dali, 1977Collotype-Continious Tone (No Dots) Lithographic Print on Thick Fine Art paper with a Deckled Edge at the top35 1/4 × 24 in These came from the printer, Collotype- Black Box in Chicago. This is a continuous tone printing, thus no dots like traditional lithography. It is closer to an original stone lithograph, but the colors are a great deal more intense. It was never cut down to the print's final dimensions, as it shows printer marks top right and along the right hand side of the print. I do not have any information on this print, the good thing is that it a high quality print, most likely printed in the late 1970's or early 1980's, and is not signed. This was never meant to leave the printer as it has not been trimmed to the final print size, or signed or numbered. About the Continuous Tone Printing Process:?Screenless lithography, by eliminating the use of halftone screens and halftone dots achieves extraordinary fidelity, fullness of tone, color and detail, impressive color saturation and clear line resolution. Museums, fine artists and publishers with exacting standards use this remarkable process to re-create their finest works of art. Continuous tone lithography (as in a photograph with no dots) evolved from collotype printing. When Black Box Collotype ultimately closed its doors in 2004, it was one of just a few printers left in the world that had mastered the collotype process. While it was a highly desirable reproduction process for the fine art world, it was a laborious, time consuming (read "expensive") process. Since there was no screen involved, a collotype print could be 27 colors without fear of a moiré. But in the old days, on Black Box’s one-unit press, those 27 colors had to be laid down one color at a time. So the most complex jobs could take months to complete.Offset lithography is far faster and less expensive than collotype. Suddenly, four colors and halftone dot patterns were "good enough" because they were so economical. Black Box Collotype was one of the last printing houses in America, if not the world that used the collotype-continuous tone process.
