Abstract
A method of manufacturing a plated steel sheet for cans which must have a good outer appearance for printing and high image clarity. The method comprises forming a plating layer directly on the surface of a steel sheet having an average central surface roughness of 0.10 .mu.m or less, the plating layer being formed by vacuum deposition. The plating layer is a metal or a metal alloy, has a thickness of from 0.01 to 5 .mu.m, and has a high image clarity.
