Figure 5.

A and B show the effectiveness of the method used to detect residues of polymerized material on the surface of the piece of fabric and the impression; the color difference between the cotton tip and the residues of nonpolymerized material clearly indicate the occurrence of inhibition. C and D show the difference between a surface with incomplete (C) and complete (D) polymerization. C shows surface undulations and oiliness on impression, which resulted from polymerization caused by the direct contact with latex (used in previous tests). D shows complete polymerization, in which the material reproduces the fabric weave accurately
