Knowledge / Luminescence / Kinds

luminescence kind: summary of the different intended styls of a luminescence

luminescence: chemical additive that glows when irradiated and thus enables the use of electronically controlled stamping machines

fluorescence: chemical additive that glows when irradiated with short-wave UV light and thus enables the use of electronically con-trolled stamping machines

phosphorescence: chemical additive that glows when irradiated with short-wave UV light and thus enables the use of electronic-ally controlled stamping machines

optical brightener: fluorescent chemical additive that improves the printing and colour effect by increasing the whiteness or com-pensating the yellow tint

with fluorescence: postage stamp issued with fluorescence as intended style

with phosphorescence: postage stamp issued with phosphorescence as intended style

without fluorescence: postage stamp iss-ued without fluorescence as intended style. This will only be shown when the same post-age stamp was also issued with fluorescence

fluorescence paper: postage stamp that was printed on paper with fluorescence in the paper pulp or paper coating as intended style

phosphorescence paper: postage stamp that was printed on paper with phosphores-cence in the paper pulp or paper coating as intended style

striped phosphorescence overprint: post-age stamp with a bar-shaped phosphorescent overprint as intended style

full-surface phosphorescence overprint: postage stamp with a phosphorescent over-print over the entire surface as intended style

with fluorescence additional printing: postal stationery issued with fluorescence additional printing as intended style

with phosphorescence additional print-ing: postal stationery issued with phosphor-escence additional printing as intended style

without fluorescence additional print-ing: postal stationery issued without fluores-cence as intended style. This will only be shown when the same postal stationery was also issued with fluorescence additional printing
