Print permanence refers to the longevity of printed material, especially photographs, and preservation issues. Over time, the optical density , color balance , lustre, and other qualities of a print will degrade.
For prints on high grade fibre papers, a period of continuous washing in clean, cold water for up to 40 minutes may be required. For modern plastic (resin) coated papers, washing for as little as 2 minutes in warm water can be sufficient to eliminate residual fixer. Washing aids (also called hypo clearing agents) can be used to make the process ...
A T-shirt printed with a flocking technique (lower half). Flocking is the process of depositing many small fiber particles (called flock) onto a surface.It can also refer to the texture produced by the process, or to any material used primarily for its flocked surface.
The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image.
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
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.
Advertisement for Ansco Cyko photographic paper, 1922. Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints.When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from ...
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.
