Smudging or smearing and re-evaporation of the vapor-deposited material in a continuously operating finishing system is avoided according to the invention by heating the textile material prior to the vapor deposition to a treatment temperature above the evaporation temperature and by using a finishing substance with a dew point in the finishing substance/transport mixture below the treatment temperature of the textile material.
