After making any sample or mixture of ink, paint, liquid paste or various type of emulsions, it should be checked/compare against standard/sample by having uniform wet-film draw down on any paper or solid surface to check its dispersion, color tone, opacity or shade differences as a physical phenomenon for further applications. 'MARSHAL' Auto Film Applicator helps to get uniform draw down & wet-film thickness for various range of viscosity & liquid resins/mediums. with the constant weight at both the sliders & precise variable speeds ensures precise draw down to generate further spectrophotometer report.
