| Résumé : |
Gold and silver inks give exquisite products a higher appreciation. In order to achieve such special decorative effects, metal pigments are applied also in printing inks. The possibilities these decorative inks offer to the graphic art industries are of great multiplicity and still have not been exhausted.
The following is a view on production and properties of the metal effect pigments as well as the resulting problems concerning the different printing applications.
The production of metal pigments has long tradition; it has developed from the gold beaters craft which existed already in 1000 B.C. The waste resulting from the gold leaf production was pulverized in a mortar, pasted with a binder and used as paint. This process was also applied on other metal leaves.
For historical reasons, metal effect pigments are therefore called "silver" - and "gold bronze", although - from the metallurgical point of view - they have nothing to do with gold, silver or bronze. They are made of aluminium, copper and brass pigments (copper - zinc-alloy). |
