LATENT PRINT DEV
PDMAC THERMAL PAPER
Preferred method for processing thermal
paper and items sensitive to heat. May
be used on any porous item needing
latent development. May be especially
useful on colorful backgrounds since
there is high fluorescence when viewed
with ALS. Best results usually visualized
between 475 nm and 515 nm with an orange
barrier filter or glasses. Product includes
1 package containing two sheets.
To extend longevity of this product always
store in the provided amber sleeve.

Like all processes, there may be a need
for longer or shorter processing time
depending on paper and environment. If
necessary a second longer exposure can
be attempted.
View with ALS 475-515 nm and orange
barrier. Photograph results. When photographing
make sure you match the lens
filter to your barrier filter.

FOR DEVELOPING PRINTS ON RECEIPTS
Remove pDMAC paper from
protective sleeve
Place evidence between pDMAC paper so
both bright yellow sides are together
Return sheets with evidence back
into sleeve
Compress sheets within sleeve for
20-30 min.

THERMANIN
ThermaNin is a ninhydrin derivative for developing fingerprints on thermal paper. Regular
ninhydrin and DFO solutions are either based on, or contain, polar solvents like acetone or
ether. These turn the top (active) layer of thermal paper gray or black. Research has found that
hemiketals of ninhydrin are soluble in petroleum ether (or other apolar solvents like pentane,
heptane) without the need for addition of polar solvents. ThermaNin develops fingerprints on
thermal paper without darkening of the surface.
