Mass-produced color graphic arts holograms

We have been developing various types of holograms. In this paper mass-produced color graphic arts holograms are discussed. The TRUE IMAGETM hologram, as it is known in Japan, is a volume-type hologram which diffracts selected wavelengths of the ambient light to selected desired angles. When replicating the TRUE IMAGETM, three lasers are used simultaneously or independently. There are four beneficial characteristics of the TRUE IMAGETM hologram; (1) Repeatable mass product techniques and few defects: a direct lamination method has been developed. (2) Looking bright and clear under fluorescent light: specially designed masters and replication conditions allows TRUE IMAGETM holograms to be seen under fluorescent light. (3) Stable chromaticities: expressing full color by developing objects, paints, mastering process and replication process. (4) Good environmental stability: use of effective adhesive films. In this paper, the first characteristic is mainly discussed.
