(i) Glue viscosity would likely affect the ridge
detail of latent prints. The low viscosity glue-coated
prints could be relatively easily be damaged by drying
with a hair dryer. Thus, although Nanmee (N), the
lowest viscosity glue, was best for plastic (94.9%)
when dried with a hair dryer, for the other three
substrate surfaces superior results were obtained with
the more gently air-drying and optimal when air-dried
for 60 min, whereas very poor results were obtained
from N on polymer and tiles when dried with a hair
dryer. In accord, Tex-Lift was the highest viscosity
glue and gave the best results when dried with the
harsher hair drier.
