Photographic printing is the process of producing a final image on paper for viewing, using chemically sensitized paper.The paper is exposed to a photographic negative, a positive transparency (or slide), or a digital image file projected using an enlarger or digital exposure unit such as a LightJet or Minilab printer.
The digital negative is the collective name for methods used by photographers to create negatives on transparency film for the contact printing of alternative photographic techniques. The negatives can also be enlarged using traditional gelatin silver processes , though this is usually reserved for negatives of 4x5" or larger due to quality ...
Transparencies can be printed using a variety of technologies. In the 1960s and 70s the GAF OZALID "projecto-viewfoil" used a diazo process to make a clear sheet framed in cardboard and protected by a rice paper cover. [1] In the 1980's laser printers or copiers could make foil sheets using standard xerographic processes. Specialist ...
At this time, Howtek also expanded into scanner technology to improve imagery for the color printers and also learned of negative image printing, transparency printing, Braille printing and printing digital information on rigid paper printing plates for the newspaper industry. This led to the founding of a new company, Presstek, Inc., in 1986. [9]
The original was either a miniature 6 x 6 cm or 35 mmm colour transparency, or else a large format 5 x 7 or 8 x 10 inch colour transparency. Three separation negatives were made on panchromatic film exposing the colour transparency through a red, green and blue filter that would eventually print in the subtractive dyes: cyan, magenta and yellow ...
Dye destruction or dye bleach is a photographic printing process, in which dyes embedded in the paper are bleached (destroyed) in processing. [1] Because the dyes are fully formed in the paper prior to processing, they may be formulated with few constraints, compared to the complex dye couplers that must react in chromogenic processing.
