TYPES OF PRINTING
Silver Gelatin Printing
The most widely used black-and-white printing process was introduced in the late 1880s. It employs papers coated with a gelatin emulsion of light-sensitive silver halide. The print is produced by exposing a negative onto the paper, either by contact-printing or through an enlarger. The print is then chemically processed, fixed, and dried. Gelatin silver prints may be toned using a variety of compounds or minerals to create a wide range of subtle hues.
Platinum paper is created by hand coating an acid-free paper with liquid platinum. The image is then contact printed onto the paper, creating a print that is the same size as the negative. The image becomes embedded in the paper, creating a three-dimensional depth specific to platinum prints. The delicate, rich platinum tones range from warm black, to reddish brown, to expanded mid-tone grays that are unobtainable in silver prints. Over the years, the only obstacle to widespread enjoyment of platinum has been lack of access to this rare process. At the outbreak of World War I, platinum abruptly could no longer be obtained. What little platinum was available went into strategic needs of the war. This shortage continued until the end of World War II. However, few photographers immediately resumed the use of platinum, largely because commercially made, platinum-coated paper was unavailable. Platinum prints are not only exceptionally beautiful, they are among the most permanent objects invented by human beings. The platinum metals are more stable than gold.
Archival Pigment Printing
Archival Pigment prints are printed with archival pigment inks on archival Fine Art paper. They are produced from digital files and offer continuous tones, smooth transitions and a vibrant, true-to-life color range. The process originated in the late 1980s and is respected by Fine Art experts, world-renowned galleries and passionate collectors. Since the inception of this process, technological advancements have led to higher resolution prints, highly archival pigments and inks, and a more environmentally-friendly print process. Prints are produced on Fine Art paper with matte and baryta finishes. Archival Pigment prints may also be referred to as Inkjets, Iris prints or Giclée
