NinhydrinHT is specially formulated for recovering latent prints on carbonless and heat-transfer (thermal) papers.
This new formulation is completely free of staining reagents (paper won’t turn purple or black), will not cause inks to run, and is non-flammable. But that’s not all, it has been successfully tested on standard papers as well. NOTE: Applying heat or any sort of fixative to treated documents is not recommended as it will darken the document.
