Good latent impressions were placed on eight different surfaces chosen by surveying forensic identification specialists in the Royal Canadian Mounted Police. Latent fingerprints were split into groups, to be treated in either a heat and humidity chamber or a vacuum cyanoacrylate chamber. Exhibits from the two chambers were paired up according to surface. Results showed that, in most cases, vacuum chamber results equaled or exceeded those from the heat and humidity chamber. Further comparison of the two chambers is recommended to verify the benefits of each in latent fingerprint identification. 17 references, 1 table, and 4 figures
