Image collection for coating team access 3

Double layer delamination. Multiple layers tend to crack
and separate. Here two layers are widely apart.

Double layer dimensions and delamination. The layers
are thicker than we thought they would be.

Stripe artifact, with and without release layer over it. The stripe
is a wrinkle in the image layer and can easily be seen with a magnifier.
The image layer looks like it was dried very fast. The release
layer is so thin we cannot measure it.

Single layer adhesion is excellent. No place on the single
layer sample has any flaking at all.

Single layer worst case adhesion is excellent even
when it is flexed. It does crack, but stays in place. The single layer
thickness is 5 microns or more, which is plenty.
8 Layer top view showing severe delamination. Multi image
layers in the sample set all have this problem.
8 Layer side view showing adhesion and strata. There is
some adhesion between layers and some splitting. The
bulk multilayer separates from the ABV at the bottom. The release layer
is apparently too thin.
Lots of holes produce the deepest blacks.
