I think that this would be quite cumbersome, paper thickness of higly coated papers vs. novel-printing paper… I believe one would have to establish this thickness for each project unless the same paper is used... > Unfortunately I threw out my old books on printing technology long ago, and > my newer one doesn’t cover bookbinding (I’m not at home anyway). I think, that many printshops do not possess neither old books including bookbinding nor do they care about the wishes of the binder … Pity, that you threw them out, but i understand, that circumstances might be such that you have to take decisions… Willi > > Hraban > > Am 19.03.24 um 17:01 schrieb Willi Egger: >> Hi Hraban, >> >> I think we should clarify this. >> >> Binding correction is a fixed amount of whitespace in the spine added to the >> inner white-space.
