(57) A lining paper to be used in the manufacture of plasterboard is given a surface finish
by printing the liner before it is used in plasterboard manufacture. The resulting
plasterboard has the printed-on surface material on the whole of one face of the board,
with a density of print sufficient that under optical examination at least 80% of
the surface of the lining paper is covered by the applied print. The printed surface
may be coloured to match the colour of a jointing material used to fill joints between
adjoining boards after they have been secured in place.
