Endlich wird nach der englischen Patentschrift ein Rohpapier mit barytierter Oberfläche verlangt, während nach der Erfindung das Rohpapier nicht barytiert werden soll, da dadurch der Zweck der Erfindung illusorisch würde, indem in diesem Falle die Wasserfarben nicht in den Papierfilz eindringen würden.
In der Einleitung des D. R. P. Nr. 96003 wird nur zur scharfen Abgrenzung da von gesprochen, dass es bekannt war, die Gelatinemulsion auf ein möglichst rauhes Papier aufzutragen. Rauh sind geleimte Papiere auch, während nach vorliegender Erfindung rohes und ungeleimtes Papier verwendet zu werden hat. Wohl heisst es dort weiter, dass dieses"rauhe Papier keine weiters präparierte Schicht, wie beispielsweise Baryt als Unterlage für die Emulsion hatte". Das steht jedoch nicht im Gegensatz zu geleimt oder ungeleimt, denn es ist eine jedem Fachmanne gelänge Tatsache, dass man seit jeher immer geleimte Papiere verwendete, die man mit Überzugsschichten versah, deren eine (Baryt) dort ausdrücklich genannt ist.
Das heisst mit anderen Worten, dass es bekannt war, rauhes, aber geleimtes Papier ohne weiteren Überzug, also insbesondere ohne Barytschichte zu verwenden.

Finally, according to the English patent specification, a base paper with a barite surface is required, while according to the invention the base paper should not be barite because this would make the purpose of the invention illusory, in that in this case the water colors would not penetrate the paper felt.
In the introduction to D.R.P. No. 96003, it is only mentioned that it was known to apply the gelatin emulsion to the roughest possible paper. Sized papers are also rough, while raw and unsized paper has to be used according to the present invention. It goes on to say that this "rough paper had no further prepared layer, such as barite as a base for the emulsion". However, this is not in contrast to sized or unsized, because it is a fact that anyone skilled in the art can manage that sized papers have always been used, which have been provided with coating layers, one of which (barite) is expressly mentioned there.
In other words, this means that it was known to use rough but glued paper without a further coating, i.e. in particular without a baryta layer.
