The Metal Construction Association (MCA) has published a white paper that discusses the elements that go into creating a color match and why there are limitations on the size of that match. The white paper, “Custom Coil Samples,” is available for download on the association’s website.
Custom color is commonplace in today’s construction, and coil coated metal is no different than many other materials. Designers frequently search for something unique and different. One important tool in making a selection is the color sample. For standard colors, this is easily accomplished since the sheet manufacturer often has standard colored coil available. Custom color samples are generally not available in the 12- by 12-inch range.
This paper discusses the three key elements required to create a custom color sample: 1) Paint Formulation, 2) Paint Application Thickness, and 3) Curing of the Painted Surface. While not an exact duplication of the true coil coating process, the custom color sample production process does provide a representative sample of the finished color appearance and will assist designers greatly in their decision-making process.
