Abstract
A transparentized paper is prepared by coating a transparentizing medium on to a paper substrate by a screen coating process. The method may be carried out on a continuous basis, and the medium may comprise an ultra-violet curable resin. Also disclosed is a universal vellum prepared according to the method of the invention, and having a first side which has a smooth texture and may be utilized for electrostatic, pen plotter and xerographic applications, and a second side having a rougher texture which may be utilized for drafting and ink-jet printing applications.
Claims10
A method for preparing a universal transparentized vellum having a first surface which is relatively smooth and a second surface which has a greater degree of texture than does said first surface, the method comprising the steps of:
- providing a generally planar substrate comprising a rag based paper having a cotton content in the range of 25-100% by weight;
- providing a transparentizing medium;
- and
- applying said transparentizing medium to the substrate by a screen coating process wherein a first surface of the substrate is contacted with a mesh screen, and a second surface of the substrate is free of the screen, and the transparentizing medium is forced through the screen and on to the substrate to deposit a controlled layer thereupon, so as to produce a coated substrate wherein the first surface, which was in contact with the screen when the transparentizing medium was forced therethrough is relatively smooth, and the second surface thereof, which was not in contact with said screen has its fibers disturbed so as to produce a texture which is rougher than that of the first surface.
