I've never have a problem. The blue dye on the Fuji paper washes out completely for me during an
initial prerinse of less than a minute in the drum. This is distinct from the image-forming dyes which
remain behind after full processing. I don't know what it's function is. The difference between the latest Fuji papers which are digitally "optimized" and the previous Super C paper is only about 5cc's of G sensitivity. Anwyay, the previous paper also was blue in its unprocessed state. Current green
laser diodes are actually filtered, so relatively weak. True green diodes are coming on the market but
are relatively expensive. I'm skeptical that the blue color of fresh paper is related to this at all.
An interesting question, but I've totally ignored it because it has no impact whatsoever on my ordinary practical workflow.
