Beschreibung
Zusammenfassung:	Methods and apparatus for forming films from liquid samples for evaluation are disclosed. The samples for films are made by dispensing at least one liquid ingredient gravimetrically. The samples are dispensed onto a substrate at respective sample location positions and are subjected to a diffuse gas flow to disperse the sample uniformly from the sample location position. Characteristics of the films formed may then be evaluated. A number of applications are disclosed but the techniques described are particularly useful to forming and evaluating paints films.
