If we do not have the chance to visualise an untreated print just by using
RUVIS alone, it is possible to applyCA(cyanoacrylate) and obtain the image
of it after that treatment. The application of superglue is easier with portable
superglue devices and superglue bags now, and these treatments can be
carried out at the crime scene. The imaging process by using RUVIS is so
successful that in the research we carried out all the prints treated with CA
could be imaged in that way. Images of the latents on porous surfaces can
also be acquired in most cases with RUVIS after CA treatment.
