In the art of making chemically embossed sheets of resinous material for use as floor, wall, desk and table coverings, a method of salvaging and recovering a backing sheet material and a potentially foamable, gelled plastisol composition on which has been improperly or inaccurately applied a printing ink composition containing an anhydride having blow-modifying properties which comprises: (1) treating the printing ink composition and the potentially foamable, gelled plastisol composition with a neutralizing, inhibiting or negating composition capable of destroying or rendering substantially ineffectual the blow-modifying properties of the anhdride without destroying or rendering ineffectual the blowing and foaming properties of the potentially foamable, gelled plastisol composition; (2) reprinting the potentially foamable, gelled plastisol composition with another printing ink composition containing a blow-modifier; and (3) blowing or foaming the potentially foamable, gelled plastisol composition, whereby chemically embossed effects are obtained as a result of the blow-modifying properties of the blow-modifier used in the reprinting process, rather than the blow-modifier used in the initial printing process.
