SONY's announcement of tlavica system shaked the world in 1981. In the new nonphotographic
imaging system, image is acquired with CCD to be converted into
electric image-signal, stored in magnetic recording media,displayed on a CR1 and
printed on a special sheet. To get a hard copy, Sublimation Transfer technology
was developed. That announcement brought about world-wide R&D of competitive color
imaging systems: Ink-jet, Wax transfer,. Sublimation Transfer(ST) and Electrophotography.
In spite of much effort,most of those were insufficient for getting
a good hard copy.
Developing sufficient ST recording media, Dai Nippon Printing started ST recording
media business in 1986. It was the first manufacturing scale production and
sale of ST recording media in the world.
Nowadays ST technology is known for its advantages: high image quality, consistency
from copy to copy, smooth tone-reproduction from high-light to maximum
density, and easiness to use.
In the following paper progress of ST recording media and the present situation
and future markets of the media will be presented.
