The iodine fuming technique can be used on both porous and non-porous surfaces. It works best on fresh prints (usually no more than a few days old). ... Since the iodine fuming technique is in principle non-destructive, other techniques can be used afterwards (e.g., the ninhydrin treatment of paper).

Several commerical kits are available to be used for iodine fuming. ... A "Liquid Iodine" method may be used if it is necessary to retard the dissipation of the developed detail, however the "non-destructive" character of iodine fuming is lost due to the application of liquid chemicals to the surface.

If it is used at all, iodine fuming is normally the first processing method attempted. Some forensics texts state that iodine fuming is used less often nowadays than formerly. That may be true in the limited sense that there are now many alternatives, but iodine fuming is still used frequently by many forensics labs.

IN ADDITION, IT WAS FOUND THAT IODINE FUMING, NINHYDRIN, AND SILVER NITRATE FINGERPRINT DEVELOPING TECHNIQUES REDUCE THE EFFECTIVENESS OF THE BLOODSTAIN CHARACTERIZATION METHODS USED IN THE STUDY.

chemicals are used to develop the print. The iodine fuming method, used in only 1 percent of developing work, will develop oil-based latent prints. Another method heats a solution of ninhydrin crystals dissolved in acetone and sprays it on the document.

The iodine fuming method is used on surfaces that are generally impractical for dusting with fingerprint powder or may have residue which will damage the dusting brush. On greasy surfaces the iodine fumes may be absorbed at different rates by different fatty or oily residues, and the latent impressions may be visible.

Iodine fuming is a method of developing latent prints on paper, cardboard, and many other paper surfaces. Iodine fuming should be used before Ninhydrin or Physical Developer (or other silver nitrate-type solution).

First, we processed the items of evidence utilizing the traditional iodine fuming technique. For this research, an iodine fuming wand was used. The items were then photographed using a Fuji S2 Pro mounted on a photography table with adjustable height track and standard side-lighting.
