The lacquer can be applied to the hologram on any layer; ie given that most surface relief holograms are produced on a thermopolymer substrate (such as PET or OPP), which is coated with an embossing lacquer, metallised and coated again for protection, Secutag can be applied as a spot or overall varnish on or between any of these layers, although any covering layer needs to be transparent so Secutag can be examined with an optical reader. However, 3S will also supply the powder if a producer wants to add the tags to one of its existing layers, or the holograms can be supplied to 3S for the application of Secutag (and as a label producer 3S can also convert holograms to labels).
