Translites are created by printing photographic images or computer-rendered images onto the material using large-format printers. Many existing translites have been created in a photographic darkroom by a mural enlarger projecting onto a strip of film up to 32 feet (9.8 m) wide. These pieces are assembled into the final size by seaming.
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
When the Riso film is exposed to the infrared bulb inside the machine, the saran plastic emulsion side opens up wherever there is an ink toner on the photocopy. Paint and other mediums can then be screened once the film is mounted on a frame. The imaging barrel inside the Thermofax is 8.5" wide, but the film can be of any length.
Photographic prints can be produced from reversal film transparencies, but positive-to-positive print materials for doing this directly (e.g. Ektachrome paper, Cibachrome/Ilfochrome) have all been discontinued, so it now requires the use of an internegative to convert the positive transparency image into a negative transparency, which is then ...
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 matrices, which are relief gelatine images on a film support (one for each subtractive primary color) absorb dye in proportion to the optical densities of the gelatin relief image. Successive placement of the dyed film matrices, one at a time, "transfers" each primary dye by physical contact from the matrix to a mordanted, gelatin-coated ...
For example it is often used to mask off areas of a design when using a photoresist to produce printing plates for offset lithography or gravure. It is also frequently used during screen-printing. Ulano also produced a yellow-(amber-)coloured masking film called Amberlith that was light-safe only for blue-sensitive emulsions. They discontinued ...
The composition of the emulsion used in Ilfochrome prints is responsible for color purity, image clarity, and archival permanence. Azo dyes, which provide stable vivid colors, are embedded in the Ilfochrome emulsion and bleached out in processing. Since the dyes are in the emulsion rather than formed from couplers in the chemistry, the image is ...
