I'm new to fibre paper and am currently experimenting with Dancq's stacking method. One problem I've encountered is the lines from the corrugated board becoming impressed upon the print. Perhaps I am using too much pressure. The board I am using comes from thick packing boxes. I can't seem to find any corrugated board on which the lines are not evident when put under pressure.

I am in England so don't have access to the material sources mentioned in previous posts.

Any thoughts would be much appreciated.
