Previous artificial latent fingerprint solution has shown unsatisfactory results. Therefore, in this study, we developed an artificial latent fingerprint solution close to the actual fingerprint composition by improving the lipid composition. We mixed lipid solution with amino acid solution at v/v ratios as follows: 2:3, 1:4, 1:5, 1:8, 1:10, 1:20. We then dropped the same amount of each proportion of artificial latent fingerprint solution on porous paper and non-porous slide glass. Subsequently, each sample was treated with Oil red O, Cyanoacrylate fuming and Basic yellow 40 staining. As the concentration of lipids decreased, the output also decreased. Both types of surfaces and all concentrations were visually confirmed very well. In addition, the reactivity to lipids was significantly higher compared to the previous artificial latent fingerprint solution. Furthermore, for the quantitative evaluation, it is necessary to conduct additional research on the printing of the artificial latent fingerprint solution.
