Process for producing smoking rod wrapper and smoking rod containing same

A process for providing a smoking rod wrapper having an increased loading of a smoke enhancing additive while avoiding bleed-through in the wrapper, said method comprising the steps of:

• providing a white, smoking rod wrapper material, said material being less than 100 microns thick;
• providing a non-aqueous, liquid vehicle having a binder, the vehicle containing particles of a water soluble smoke enhancing additive for forming an ink, the particles being insoluble in the liquid vehicle and substantially all the particles having sizes in a range of 5-80 microns, the smokeenhancing additive being present in an amount in a range of 33-70% by weight of the ink, the smoke enhancing additive being selected from a class consisting of biuret, ammonium compounds, urea, menthol borate, tobacco components, tobacco extracts, synthetic flavorants, glycols, hydrophylic smoke dilutants, sugars, organic acids, sodium carboxymethyl cellulose, alkaloids, glycerol, and ethyl stearate;
• printing one side of the smoking rod wrapper material with said ink to provide an effective smoke-enhancing amount of the additive on the wrapper material;
• and
• drying said ink on the material to form a deposit having an impregnated ink part that is impregnated into the surface of the wrapper material and a raised part that is raised above the surface of the wrapper material, the smoke-enhancing additive being present substantially only in the raised part.
