A New AntiCounterfeiting Feature Relying on Invisible Luminescent Full Color Images Printed with LanthanideBased Inks
wileyonlinelibrary.com to authenticate are therefore important for the protection of brands and valuable documents such as bank notes, diplomas and certifi cates. Luminescent tags or labels are appreciated security elements for protecting authenticatable articles. One way to incorporate luminescent materials as luminescent security elements is to print them with luminescent inks. [ 2 ] Nowadays...
متن کاملSurface Modification of Adhesives, Inks and Coatings –
It is well documented that plastics surface modification techniques can greatly improve the acceptance of a wide variety of coatings, adhesives and inks for improved decoration, painting and adhesive assembly. By increasing the hydrophilic characteristics and surface-free energy of plastics, bond strengths can be improved dramatically. It is theorized that interlayer adhesion between decorating...

متن کاملModeling Dot Gain and Inks Interaction
Multispectral printer characterization requires an effective model to map printer input digital counts into reflectance spectra and vice versa. This paper presents a novel strategy to describe dot gain and interaction among inks in the definition of a printer model employing the Yule Nielsen Spectral Neugebauer equation. The method proposed, that requires the printing and measuring of a trainin...
متن کاملSearching for Invisible and Almost Invisible Particles At
We explore the techniques, cross sections and expected signal significance for detecting invisible and almost invisible particles at LEP2 and the NLC by means of a hard photon tag. Examples from supersymmetry include the lightest chargino and second lightest neutralino when their masses are nearly the same as that of the lightest neutralino (the LSP), and invisibly decaying sneutrinos. The impo...
