Common latent image effects can be seen on the New Taiwan Dollar 1000 banknote, where rotating the viewing angle reveals the hidden number "1000". This latent image effect can only be produced with intaglio printing. We do not use intaglio printing, but achieve a similar effect through the design of patterns and printing techniques. Because of the higher production threshold, it has an anti-counterfeiting effect. By rotating the viewing angle, two different pattern changes can be seen, making it easy for users to identify authenticity.
