Liqui-Lift Technique--Compressed Air

"How do you come up with some of these ideas and Techniques?"

This is a question I am often asked. Here is an example of how it comes about.

I was in Portland, Oregon for the NW Pacific IAI Conference in May and was conducting a class on lifting latent prints off textured surfaces.

The first method I showed was using Liqui-Lift, which you place a drop of the Liqui-Lift on the latent print and blow through a straw to spread it out to a thin layer over the latent print. I noticed two officers in particular and not to mention there names were blowing so hard that their cheeks were puffed out and their faces were turning red. I informed them that it was not necessary to blow that hard to get the job done. Off the top of my head I told them that they could use a compressor to blow out the Liqui-Lift it would be easier and healthier for them.

Bingo, a compressor or how about using a can of pressurized air, the type you can buy at the office supplies store which is used for removing dust from computers and printers.

Apply a single drop of Liqui-Lift next to the latent print. Using the compressed air, blow the Liqui-Lift thinly over the latent print. The thinner the better. This method works very well, just do not hold the nozzle to close to the Liqui-Lift. Never turn the can upside down or shake when in use, liquid will come out. As always practice at the office before trying it out on an actual case. By having a thin layer of the Liqui-Lift over the latent print it will dry much faster.
