I think the problem of the red bleeding through, could be because it will be thicker in the scribe lines and may have needed to cure longer than the flat surfaces.
Many reds, and some deep blues, take longer to cure because of the pigments used in them.
Push a toothpick into the areas that have bled to see if it leaves any marks. If it does then it still hasn't cured fully yet.
Or try a dark pinwash in the these areas to pick out the scribed lines.
As regards the transfers, have you any more you can double up with to obscure the colours beneath!
Just an idea.
