Definitions
- the present invention relates to the use in offset printing plates of a new aquaphile layer.
- plates having a hydrophilic surface that is to say accepting water but refusing ink
- an ink-absorbing material which accepts ink and refuse water.
- the encrophilic material can be for example copper, brass, a varnish, a lacquer or a resin .
- an aquaphile and encroppable surface of offset printing plate can be obtained by using, on any support, a layer of a tin-nickel alloy containing about 65% by weight of tin and 35 % by weight of nickel.
- the relative percentages of tin and nickel may vary between 57% and 75% of tin, the rest being nickel.
- the alloy of the same structure being between 57% and 69% tin, the rest being nickel.
- the usable alloy may comprise, in addition to the tin and nickel present in the proportions mentioned above, certain other metals, in small quantities, such as lead, cobalt, zinc, cadmium, copper, manganese. and phosphorus.
- the aquaphile layers according to the invention have thicknesses greater than approximately 1 micron.
- alloys which can be used according to the invention in offset plates are known in themselves but have never been recommended for the production of an aquaphile surface of offset plates and it has been found that, for this use, said alloys have very good properties. interesting.
- the supports on which the tin-nickel alloy surfaces are deposited are very diverse, for example brass, stainless steel, steel, black iron, tinplate (tinned) aluminized steel, zinc-plated steel, aluminum ... These supports may have been covered , before depositing tin-nickel, copper, brass, bronze, chromium, nickel tin in the form of a metallic intermediate layer capable of increasing the corrosion resistance of nickel tin or modifying (making matt for example) the appearance of the tin-nickel layer.
- these supports can be treated so as to have. a matt surface either by means of an electrochemical, mechanical, chemical treatment, or by using known baths or techniques.
- the dry plate is covered with 2 microns of photosensitive layer P R 12 of the P.C.A.S. and dried at 45 ° for 3 'and at 85 ° for 6'.
- This plate uses, on the one hand, tin-nickel to take the water, on the other hand, the PR 12 layer, then quickly the copper to take the ink. It is bi-metallic.
- the plate After sunstroke with a positive and development, the plate is rinsed, prepared, rinsed and erased.
