Abstract
The invention provides a photopolymer package for use in making a hand stamp plate, the package consisting of a sachet containing a photocurable liquid polymer, the walls of the sachet being formed of material capable of being released from the cured photopolymer. Methods for the formation of the package and the hand stamp plate are also provided. The invention eliminates the requirement for the use of a backing layer in the package and thereby offers significant advantages over the prior art in terms of cost and efficiency.
