Info about the Art Edition from Robert Place
First, the art edition is printed on heavy weight 100% cotton rag paper. This is the same type of paper that was used by artists in the Renaissance and, as you can see, there drawings have lasted 600 years without falling apart. it is naturally acid free, unlike wood-pulp paper which starts deteriorating from the acids that it contains almost immediately. I have books on pulp paper that are only 30 years old and they are in bad condition with brown spots and brittle areas. the acid free paper that many publishers now use lasts longer but eventually it develops acids and deteriorates. Plastic coating, the way most cards are produced, will help stop deterioration by keeping air away from the paper fiber but the best quality is cotton or linen rag paper. That is what is used in the art world for art prints.
The Art edition is also a giclee print, printed on an Epson R2400 printer which uses archival inks designed to last at least 300 years without fading. That is because they are pigment based instead dye based. Dye based ink is what most printing is done with. I have a sheets sent to me from the printer as proofs in which all of the cards from the Buddha Tarot are printed, one for all of the fronts and one for all of the backs. They are rolled up with the one with the backs facing out and leaning on the book self next to the window in my office where it gets direct sunlight. It has been there since 2004 and where the sun hits the red background has faded to a pale yellow and the black lines are only a slightly darker tan. In contrast I have prints that I printed with pigment ink that are framed and have been hanging on the wall under a skylight for 10 years where they get direct sun and there is no change in their colors. Of course most people do not keep their pulp cards on display which protects them from the sun.
Besides the paper and the ink, I give the art edition four coats of clearcoat varnish, which stops ultraviolet light from getting to the surface and extends the life of the colors even longer. Besides this, is protects the surface from wear and moisture. I have taken a sample card that I printed and coated with clearcoat and held it under the faucet and the ink does not run. One should not rub the surface when it is wet because the surface will tear more easily but the coating protects the ink from running which is the one disadvantage of giclee printing. On the earlier copies of the Art Edition I was having them laminated which offers even more protection from wear and moisture. But it was a visibly thicker coating and the clearcoat is less visually intrusive.
