olemus
üks taktiiltunnuste loomise meetodeid,
trükk sügavauurdelise vormiga, mis tekitab alusmaterjali pinnalt kõrguva reljeefse kujutise;

= one of the methods of creating tactile features: printing with a deep-grooved form that creates a relief image rising from the surface of the base material; this image is easy to check in the sidelight
