increased the gum concentration in order to accommodate (without staining),
the amount of pigment that was required. Once I reduced the gum and pigment
concentration, the adhesion was improved and the top layer behaved. <

Happy for you!

Could be something about the structural/physical properties of the specific
pigments that you were using or something else, who knows? Don't dig too
much, go for the image! ;)
