 preferable as a heat-insulation support having a low thermal conductivity and a high heat-insulation effect among the supports described above. The thickness of the support is in the range of 0.05 to 5.0 mm, preferably in the range of 0.05 to 2.0 mm, as described previously. Dimensional accuracy becomes poor when the thickness is smaller than 0.05 mm. When the thickness is larger than 5.0 mm, flexural strength is insufficient when the plate is wound on a printing machine, thereby causing cracks in the support itself.
An aluminum plate is particularly preferable as a support having heat-insulation effect, since it is cheap and has excellent dimensional stability.
A suitable aluminum plate may be an alloy plate having as main components a pure aluminum plate and aluminum, with a minute amount of foreign elements.
The foreign elements contained in the aluminum alloy may be silicon, iron, manganese, magnesium, chromium, zinc bismuth, nickel and titanium. The total amount of the foreign elements in the alloy is 10% by weight or less. While pure aluminum is favorable in the present invention, a minute amount of the foreign elements may be contained in aluminum, since production of perfectly pure aluminum is difficult in view of refining technology. The composition of the aluminum plate to be used in the present invention is not particularly restricted, and aluminum plates of conventionally known and used material may be appropriately used. The aluminum plate to be sued in the present invention has a thickness of about 0.1 to 0.6 mm, preferably 0.15 to 0.4 mm, and a thickness of 0.2 to 0.3 mm is particularly preferable.
Prior to roughening the surface of the aluminum plate, a degreasing treatment with a surfactant, an organic solvent, or an alkaline water solution may be administered to the aluminum plate in order to eliminate rolling oil on the surface as needed.
The surface of the aluminum plate may be roughened in accordance with various methods. Examples thereof include a method in which the surface is mechanically roughened, a method in which the surface is electrochemically dissolved and roughened, and a method in which the surface is chemically roughened by selectively dissolving the surface. Methods such as ball polishing, brush polishing, blast polishing and buff polishing methods may be used for the mechanical roughening method. Examples of the electrochemical roughening method include a method in which an alternating current or a direct current is passed

The thickness of the support is in the scope of 0.05 to 5.0 mm, preferably in the range of 0.05 to 2.0 mm, as describe previously. Dimensional accuracy becomes poor when the thickness is little than 0.05 mm. When the thickness is larger than 5.0 mm, flexural strength is insufficient when the plate is wound on a printing car, thereby causing cracks in the support itself. 
 An aluminum denture is particularly preferable as a support hold estrus - insulation impression, since it is cheap and has excellent dimensional stability. 
 A desirable aluminum plate may be an alloy plate having as main components a pure aluminum home plate and aluminum, with a minute amount of foreign elements. 
 The foreign elements contained in the aluminum alloy may be silicon, iron, manganese, magnesium, chromium, zinc bismuth, nickel and titanium. The total amount of the alien elements in the alloy is 10% by weight unit or less. While arrant aluminum is favorable in the present invention, a minute amount of the alien elements may be contained in aluminum, since production of perfectly arrant aluminum is difficult in view of refining technology. The composition of the aluminum plate to be used in the present invention is not peculiarly restricted, and aluminum plates of conventionally known and used material may be appropriately used. The aluminum plate to be action in the present invention have a thickness of about 0.1 to 0.6 mm, preferably 0.15 to 0.4 mm, and a thickness of 0.2 to 0.3 mm is particularly preferable. 
 Prior to roughen the surface of the aluminum plate, a degreasing treatment with a surfactant, an organic solvent, or an alkaline water solution may be administered to the aluminum denture in order to obviate rolling oil on the open as needed. 
 The open of the aluminum plate may be roughen in accordance with various method. Examples thereof admit a method in which the surface is mechanically roughened, a method in which the surface is electrochemically dissolved and roughened, and a method in which the surface is chemically roughened by selectively dissolving the surface. method such as ball polishing, brush shining, blast polishing and buff polishing methods may be used for the mechanical roughening method.
