摘要:
A plate material the surface of which is formed of film including as its major component a material whose surface changes from a lipophilic state to a hydrophilic state by a photocatalytic reaction and returns to a lipophilic state when subsequently subjected to a heat treatment is used for making a printing plate. The substantially entire surface of the plate material is uniformly exposed to active light and an image is written in a heat mode on the surface of the plate material, which has been exposed to the active light.

A plate material the surface of which is formed of film including as its major component a material whose surface changes from a lipophilic state to a hydrophilic state by a photocatalytic reaction and returns to a lipophilic state when subsequently subjected to a heat treatment is used for making a printing plate. The plate material is exposed to active light over the substantially entire surface thereof with image-wise part kept unexposed. The part exposed to the active light becomes hydrophilic and repels ink while the part unexposed to the active light is kept lipophilic and receives ink. When the plate material is subsequently heated, the hydrophilic part is rendered lipophilic and the plate material can be reused.
摘要:
There is prepared a printing plate on which a material being hydrophilic due to light energy at a first temperature and being hydrophobic at a second temperature due to heat energy which is lower than the first temperature is provided. First, the whole surface of the printing plate is forcibly made either one of hydrophobic or hydrophilic. Next, a region having the other nature out of hydrophobic and hydrophilic is formed so as to correspond to an image to be printed. Then, ink is supplied onto the region having hydrophobic nature to conduct offset printing.

摘要:
An offset printing plate precursor comprising a substrate having provided thereon a layer containing a substance capable of absorbing radiant rays and converting the radiant energy to heat energy, and a thin layer, wherein printing is performed by following the steps of: (a) subjecting the printing plate precursor to irradiation with active light, (b) subjecting the printing plate precursor to irradiation with light/heat convertible radiant rays or heat treatment, to thereby imagewise distribute a hydrophilic area and a lipophilic area of the thin layer, and (c) bringing the thin layer into contact with printing ink to form a printing plate in which the lipophilic area has received the printing ink, to thereby perform offset printing.
