Use of Multi-Effect Ink
It is possible, in some cases, for the same ink to combine several effects:
+/- iron, +/- slate, +/- scent, +/- soft touch, +/- photochromic, +/- scent, +/- glitter, +/- photoluminescent, +/- invisible fluorescent, +/- Sparkly, +/- metallic, +/- scratchable, +/- scratchable, +/- scent
However, it should be borne in mind that it is impossible to retain the optimal properties of each
Ink used in the mixture, because the effect will be “diluted”.
