Plastic-based paper type. The most common paper type for printing colour images as it gives greater gloss potential than fibre-based papers (e.g. supergloss on Fujiflex).
R-type papers work in the opposite way to traditional papers. A transparency (positive) is projected onto reversal paper which thus develops a positive image.
Chloro-bromides share the features of all silver gelatin prints, giving deep rich blacks and crisp whites on a high gloss paper, as well as having good archival properties. Compared with silver bromides or silver chlorides, they have a warmer brownish-black tone.
Digital printing that produces images directly on to the material (e.g. canvas or special paper surfaces) from a digital file through a stream of very fine dye drops controlled by the computer system. (See also Giclée prints)
A positive is, obviously, the opposite of a negative – that is, it is an image which is not reversed. Positive images are made through a double negative: silver salts react to light producing a negative which, when projected onto photographic paper (more silver salts), produces a positive.
Dye, unlike pigment, dissolves completely in solution (pigment-based inks leave tiny particles floating in the solution). This means that dye-based inks are entirely absorbed into the paper that they are printed on – the image is in fact a highly controlled stain. The resulting images can thus appear very slick and even, with a vast…
