Pigment/fluorescence threshold mixing method for printing photocopy-proof document

摘要: Commercially available pigments mixed with fluorescence compound to obtain print stuff mixtures for transfer thereafter mattes. The obtainable thereby are used securitY and face-value documents which will be color copier resistant, that is, not accurately reproducible or replicable by a photocopier. An empirical test is provided allow the ordinary skilled printer determine best titer of commercially in ink/pigment mixing scheme.
