Previous Workflow in G3:
I have a Thin and a Black Master; if needed, I added an Intermediate in-between. normally I set a value to {140}, then re-interpolated and afterwards I changed the value of the Intermediate to {100} without re-interpolation. That way, I could get a thicker glyph that fitted to the greyscale. Depending on the letter, I sometimes used {136} or {138}, it was a try and error until it worked.
Now in G4; I have an Interim Master. I can activate the Master and re-interpolate at the given value of the Master. This works fine, but it gives me a glyph that is still too light.
So I tried to stay to my previous workflow. I keep the Interim Master deactivated and added an Intermediate Layer to copy it into the Interim Master later. Unfortunately, the Intermediate gives me just an empty layer, although the letter interpolates and exports correctly. This happens to all glyphs, all Intermediates give me an empty layer.
What am I doing wrong?
I could thicken the Intermim Master with RMX Tools, but it feels like extra work…
