Analysis in producing large format embossing hologram

Flat-press embossing is an economic method of producing large format embossing hologram in small quantities and variable types. We use upper bound and lower bound theory to get the proper embossing pressure. From the transfer function of embossing we correct the values of the embossing temperature and holding time. From our analysis, we improve the product quality and reduce waste. Some problems like the wrinkling, curling, and breakage in plastic plate or the short life in the embossing master can be eliminated under the proper operation parameters. We believe this system will be valid in manufacturing the prototype of the holographic products.
