#INK DRAWDOWN MANUALS#
Nevertheless, none of the Brand Manuals has neither any remarks, comments or warnings of color deviations nor indications of acceptable color tolerances. This will result in unpredicted color differences of up to 35 ΔEab or 8.3 ΔE2000 when some of those Brand Colors are reproduced. 90.4 % of the Brand Manuals also specifies their Brand Colors with supplementary CMYK-values even though only 45.8 % of those Brand Colors are achievable by using the process colors CMYK. 91 % of the Brand Manuals specifies their Brand Colors as either PANTONE or PANTONE C. By examining and analyzing more than 300 different Brand Colors from 156 Brand Manuals by reputable local and Global Brands including 28 of the 100 Best Global Brands (Interbrand 2015) (see Appendix) and by numerous of visits and interviews with responsible professionals from both sides throughout the years it is obvious that there is an alarming lack of communication between technical experts and design experts. When it comes to providing technical guidance, defining and describing their Brand Colors, they all fail. Holding these applicators at a lower angle will reduce coating thickness down to about half of the maximum value.From top class Universities and governmental organizations to high-end global brands and well-known local brands, a surprising consistency of inattentiveness has been published in these companies’ prestigious Brand Manuals and Brand Guides. (2) A = appropriately sized metering rod B = appropriately sized ACCU DYNE Applicator TM, held at a 45° angle, which applies the maximum possible yield for each coating gate. (1) Wet film thicknesses are approximate, and will vary slightly depending on coating viscosity, percent solids, and substrate absorptiveness. To determine dry film weight, multiply table values by percent solids. WFT,Ĭoating weights are based on a coating density of 1 g/cm 3 (8.345 lb/gal). Please email or call us for advice on your specific application. A Universal Blade Applicator can produce any wet film thickness from 0 to 5 mils or 0 to 25 mils, depending on the design chosen and how it is adjusted. Additionally, many alternative coating thicknesses can be produced with special order metering rods.
The following table shows the wet film thicknesses, coverage, and wet film weights that can be produced with our stock metering rods and ACCU COAT Applicators™. Even when the drawdown method does not directly emulate a planned production process, it may be a useful pre-production test to screen materials or drying and curing methods. The tools described in this section open up a variety of test options. For best results, tests should be performed on a Diversified Drawdown Platform™ or a similar flat surface. Drawdowns allow easy evaluation of wettability, opacity, color match, gloss, tack strength, drying weight, dye uniformity, degree of pigment dispersion, and other attributes. Since most coating properties are thickness-dependent, it is imperative that the optimum thickness be determined for each application. The drawdown test is a fundamental laboratory technique which is used to evaluate interactions between flat surfaces (such as film, foil, and paper) and a myriad of inks, coatings, paints, suspensions, adhesives, colloids, powders, etc. Note: drawdown is shown at accelerated speed.
