Nice to see a user handle that I recognize from the MMW boards!
Having restored Masterworks for most of this century, I'm well versed in these battles/discussions.
I'm most DEFINITELY avoiding Glossy paper like the plague.
I'm obviously using the 25% colour increments to restore colour, and then scaling them back. If I'm doing the colour portion of book using this method, I just haven't found that proper amount to scale back yet.
My biggest beef with these books is the obscene amount of colour out of registration. See below!
