RESULTS
When dark particles in the SPR were used, the best quality of developed latent print on the wet surface was obtained from SPR II for every type of soaking solution. SPR II contains molybdenum disulfide, tergitol NP-7 and choline chloride, with a proportion of particles and detergent at 13.1. The fingerprint image was nearly complete (moderate), and had a ridge count of 12.98 (Tables 1 and 2).
