Patent
CA 2287828
In a method of drying inks which are printed on to a paper web in the printing mechanisms of a rotary intaglio printing machine and which are diluted by means of a solvent, the paper web, downstream of each printing mechanism, passes through a drier having a substantially closed housing through which flows a gas which serves to pick up and carry away the solvent, To achieve a reduction in the residual solvent concentration in the finished printed product in spite of an increased speed of the paper web. the drying gas used in at least one of the driers is an inert gas, the through-out thereof through the drier being so selected that a solvent concentration which is very high in comparison with drying with air occurs in the drier.
