Abstract
The process for making a surface covering having an embossed wear surface, including embossed design portions which differ in elevation and shading, by depositing a liquid resinous base coating onto a backing, depositing a layer of resinous dryblend onto the liquid resinous coating while it is still wet, heating to sinter the dryblend and at least partially set the base coating, producing a design on the sintered layer by applying settable resinous ink to at least a portion thereof in sufficient amounts and viscosity to permit penetration of the ink into the dryblend layer to a depth of about 10 mils (0.254 mm) at the points of application, at least a portion of the design being formed by applying the ink in minute separate but closely spaced deposits, and heating the composite structure for final fusion to form a non-porous sheet wherein the design areas containing the closely spaced ink deposits may differ in shading and elevation in their ink-containing and non-ink-containing portions. These design areas may also differ in shading and elevation from the other ink-containing and non-ink-containing areas of the sheet. The resulting sheet may then be passed around a smooth (or textured) roll with the face of the sheet in contact therewith to provide any smoothing or texturing effect desired. Optionally, an overall resinous top coat may be applied.
