ABSTRACT:
A mold tool for paper relief engraving provides a mold cavity, a mold plunger and a folder for being detachably fixed with the mold cavity and the mold plunger at the inner sides thereof. The mold cavity and the mold plunger are doubly etched to create pattern nests and pattern projections respectively with smooth fine contours and edges such that the relief engraved paper can be tightly pressed in a way of the flat part of the paper being kept without wrinkles and deformation at the nests and the jut up part of the paper extending sufficiently. Hence, the relief engraved configuration presents outstanding sense of beauty especially for making a greeting card.
