Fade to grey
Well, since my last post, the black areas have faded to a faint grey now. They should not require many more sessions until all the black has gone. The new laser is fantastic. Apparently, there are only two of this kind in the country. Even on the very faint black areas, the laser still picks up the ink and there is a satisfying popping as it reacts with the ink. Still got the blues and greens, but, maybe, this new laser, in time, will work its magic on those colours, too.
