Abstract: Conventional methods of making holographic labels use separate, stand-alone machines for embossing, laminating, printing, and diecutting. This means that embossed material must be transferred and loaded into the laminator, that laminated material must be transferred and loaded into the printer, and that printed material must be transferred and loaded into the diecutter. Unfortunately, transferring and loading material into the separate machines is not only time consuming but also introduces errors, particularly in achieving accurate registration, or alignment, of embossed, printed, and diecut patterns. Accordingly, the inventors devised an in-line rotary microembosser for use with a rotary laminator, printer, and/or diecutter. One embodiment, or implementation, of the invention includes a rotary microembosser operatively coupled in line with a rotary laminator, a rotary printer, a rotary diecutter, or another web processing device to concurrently process a continuous web.

Abstract: Holographic labels are used on a variety of articles of manufacture for security, authenticity, or aesthetic appeal. Manufacturing a holographic label or sticker typically entails microembossing, that is, imprinting or cutting, microscopic grooves into a clear plastic sheet with a shiny aluminum coating. The grooves diffract light and form a three-dimensional image, such as the dove commonly found on Visa™ brand credit cards. Unfortunately, conventional microembossing machines, or microembossers, suffer from a number of problems. For example, these microembossers include two large base rollers that move back and forth in sequence to contact a shimroller. The clumsy back and forth movement not only limits how fast embossing can occur but also causes misalignment of embossed images. To address this and other problems, the inventors devised an exemplary microembosser which includes a single base roller and a shimroller which one or more unique features.
