12 January 1994 Analysis in producing large-format embossing holograms

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 temperatures 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.
