ALUMINIUMBLECH MIT RAUHER OBERFLÄCHE |
摘要 |
<p>Aluminium sheet suitable for use as a lithographic plate support has a surface that is uniformly rough by virtue of: a rippled topography having an aspect ratio of at least 1.3 on a sale of 5-200 mum; and a superimposed pitted structure on a scale of 1-20 mum. A method of making the aluminium sheet involves pack rolling two aluminium ribbons to generate facing surfaces having the transverse rippled structure; followed by a small amount of a conventional roughening or graining treatment to develop the pitted structure.</p> |
