On a 21 step tablet, the last black (#21) I assume calls in the Photo Black (K7 Selenium) on glossy surfaces like a luster.
The steps look good at an oblique angle, but when the G.O. goes on, the #21 black seems to get duller like it sucked up the GO? Rest of steps look fine and shiny from the G.O. just that last black looks dull and flat.
Does this mean I need to use more G.O. or maybe a second pass later after the first layer of G.O. goes on? Lacquer spray afterwards?
