Why are some pigment foils not opaque?
Many years ago lead, and other heavy metal pigments such as chromium and cadmium based, were used in the manufacture of hot stamping foils. These pigments contributed to many of the yellow, red, and green shade foils. They were economical and they were also opaque. However within the past ten years, there has been much concern with the health related issues related to lead pigments. The switch over to safer organic pigments have caused opacity to suffer. Custom Foils does not use lead or any of these heavy metal pigments. We have phased those pigments out since the late 1980’s. There have been new advances in high performance pigments which are more opaque, trying to achieve the levels of lead pigments, but they do not come without high cost. There are other techniques to achieve high opacity, but in general, they add to cost. Metallic foils have a coating of metallized aluminum which gives it greater opacity than pigment foils.
