Inventor: SCHELL HELMUT
IPC: B41N1/08
Filed: 1988-04-22
Granted: 1993-07-30
Abstract: 1. Support material and aluminium planographic printing plate, and process for its manufacture. 
<??>2.1 Previously, pure aluminium or manganese-containing alloys have been used as support material for planographic printing plates with a baked photo-layer. Such alloys have an essentially higher thermal stability than pure aluminium but during electro-chemical roughening in HCl or HNO3, dark surface colorations and different grain structures appear which have an adverse effect on the technical copying properties or their general ability to respond to roughening treatment. The object is to find a support material which has a pale uniform surface after the roughening treatment, a general ability to respond to roughening treatment and simutaneously high stability under baking conditions. 
<??>2.2 A material with a fine precipitation micro-structure (degree of dispersion D < 50 phases/ mu m<3>) is produced from an aluminium alloy containing 0.2-0.6% Fe, < 1% Mn, < 0.25% Si and Cu under adherence to particular conditions during the heating and shaping. The ratio of the dispersed phases AlMnSi:AlFe:AlMn lies between 1:1:2 and 1:1:3. Because of dissolved Fe and Mn as well as the fine precipitations, this material possesses a high thermal stability. Since the very fine Mn-containing phases are present only in small proportions, the surface quality necessary for planographic printing plates is achieved by the electro-chemical roughening in HCl as well as in HNO3. 
<??>2.3 Manufacture of aluminium planographic printing plates.
