Abstract: A water soluble pouch containing a substrate treatment agent, the water soluble pouch having printed characters, and a process for making the same.

Abstract: A process including the steps of: providing a water soluble film; providing an ink including between about 5% and about 30% by weight a solvent selected from the group consisting of diols, cyclic polyols, diglycols, triols, polyols, and mixtures thereof; and applying the ink onto the water soluble film.

Abstract: Apparatus for producing pouches including a source of printed water-soluble PVOH film, a second source of film, a source of composition, a pouch making unit comprising a filing system to form pouches from the first film, the second film, and the composition, a control system for monitoring and adjusting the position of the pattern onto the pouches. Pouches made by the apparatus.

Abstract: Apparatus for producing a printed film, the apparatus including a roll of water-soluble film to be printed, the film including a resin that includes polyvinyl alcohol (PVOH) or a copolymer thereof, a rotating drum, a printing system for printing a printed pattern onto the film, the printing system including a plurality of separate printing stations arranged on the rotating drum. Printed films made from the apparatus.
