Abstract: Apparatus and method for characterizing perceived visual quality of holographic materials, such as diffraction gratings. A white light source directs a collimated beam onto an embossed material. The first order diffracted light strikes a white background directly in view of a digital camera, which records an image. The image is analyzed to calculate total color intensity of the diffracted light and an estimate of the color distinctness. The data is compared to other samples to determine relative visual quality.

Abstract: A labeling apparatus and method for continuously applying a layer of a radiation curable adhesives to plastic, sheet fed, cut and stack, labels, irradiating the adhesive on the labels, prior to and/or subsequent to adhering the labels to containers, e.g., a bottle, to render the adhesive sufficiently tacky to effectively permanently seal the labels to containers in a commercial labeling machine. The plastic labels can be clear, opaque (including metallized) plastic films and can be retained in a dispensing magazine prior to the application of the radiation curable adhesive to the labels.
