STRIP FOR LITHOGRAPHY PRINTING PLATE CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a strip for manufacturing a lithography printing plate support having an improved micro crystal surface layer, capable of faster manufacturing speed during manufacturing of the lithography printing plate support.SOLUTION: In a two-dimensional microprobe analysis performed by a mapping method of a surface area of a micro crystal surface layer of a strip, a surface part in the measured micro crystal surface layer having an intensity ratio I/Iof over 3 in a specific area of Kray in an X ray emission spectrum of oxygen is less than 10%, preferably less than 7%.
