![]() Common wet process chromogenic papers used for Digital C-Prints include Kodak’s Endura and Fuji’s Crystal Archive papers. The Digital C-print digital exposure systems expose the paper using red, green, and blue lasers or light emitting diodes, and then use the chemical process of traditional C-prints to produce the final print. Digital C-Printĭigital C-prints (also known as Lambda prints or Lightjet prints based on common systems used to create them) are created when a digital file is used with a specialized digital exposure system such as the Durst Lambda, Océ LightJet or ZBE Chromira to produce a C-PRINT. By using typically 4-7 monochromatic inks and by excluding color inks, improvements in metamerism, tonal transitions, longevity, and detail are possible. Dedicated B&W Inksĭedicated black & white inks such as the Piezography printing system from Cone Editions Press are monochromatic pigment ink sets used in converted color inkjet printers for the utmost in digital black & white printing quality. ![]() Objects that are relatively flat and opaque may be successfully printed using cyanotype photography. A positive image may be produced by exposing the treated paper to a source of ultraviolet light such as the sun and then developing and washing the print, washing away water-soluble salts and leaving non-water-soluble Prussian blue in the paper. The paper or other surface is treated with chemicals such as aqueous potassium ferricyanide and aqueous ferric ammonium citrate. CyanotypesĬyanotypes are prints created by exposing treated paper (or other medium) to sunlight in order to imprint an image onto the paper with typically a cyan-blue tint. The cibachrome process utilized a stable polyester base and a dye destruction technique to produce visually striking, relatively long lasting, and accurate color reproductions of positive originals. CibachromesĬibachromes, also known as Ilfochromes, are a common name for chemical prints made from a slide original (a positive-to-positive photographic process). A digital C-Print uses specialized equipment and a digital file rather than a color negative to produce the C-print. The exposure phase of a type C print is accomplished using a traditional photographic enlarger, using color filters to adjust the color balance of the print. A C-print is a negative-type color photographic paper which has at least three emulsion layers of light-sensitive silver salts used to produce the photographic image when the appropriate chemicals are applied. C-PrintĪ C-print, also known as a chromogenic print or Type-C print, is a chemical photograph created traditionally created from a film negative using a “wet process” such as RA-4. ![]() Baryta papers for the digital darkroom have all the archival characteristics you would like and importantly, have a very similar look and feel to great air-dried fiber-based silver-gelatin papers. Inkjet-compatible baryta papers use a multi-layer coating that includes baryta over a base such as cotton rag or alpha cellulose. As such, the use of baryta in papers for photographic printing has a long history of archival permanence. Baryta (pronounced bah-RYE-tah) papers have their origin in the traditional darkroom as fiber-based silver gelatin prints typically used a white layer of barium-sulphate gelatin applied to the paper ground and beneath the light-sensitive layer to help provide pure whites and rich blacks. The baryta gives the paper much of its smoothness, whitepoint, and, interestingly, a smell just a bit reminiscent of the darkroom. ![]() Archival (in the context of prints) is a term with no definite scientific meaning but is generally used to describe an item that will retain its original properties over a long period of time Barytaīaryta papers have a multi-layer coating that includes barium sulfate, a white clay-like substance, over a paper base such as alpha cellulose or cotton rag. ![]()
