“…The deposition conditions affect the concentration of components within the fingerprint at the deposition stage [3,16,20,26,59,77,78]. These conditions include the pressure of the deposition, the duration of the contact, the dimension of the finger in contact with the substrate, the digit used for deposition, and how recently the donor washed their hands [3].…”

“…This is particularly relevant for enhancement techniques, such as iodine fuming, solvent black 3, basic violet 3 immersions and small particle reagents, which target the constituents most readily lost under vacuum conditions [78,116,118]. These changes to composition may result in a decrease in the quality of the enhancement if the fingerprint has been previously subjected to a vacuum system [116].…”

“…The effects of pressure have been the subject of specific studies because of their unpredictable nature. Jasuja, Toofany, Singh, and Sodhi () demonstrated an increase in the quality of ninhydrin‐developed fingermarks as a function of pressure and sweating time. Fieldhouse () found out that an excess or a lack of pressure during fingermark deposition lead to visible differences in quality when the marks are developed with CA fuming.…”

Fingermark detection is a very active field of research in forensic science, with many different strategies currently investigated to always improve detection rate. However, each new technique has first to be optimized, assessed and validated with many fingermarks from multiple donors across a wide variety of substrates before being included into laboratories operating procedures. This process often requires the collaboration of research groups and operational laboratories from different countries, and it takes several years for a new method to be applied routinely in casework. One particular challenge that makes the process from R&D to operations complicated is the significant intrinsic within‐ and between‐source variability of fingermarks. Many studies partially addressing fingermark variability have been reported but a comprehensive approach to the problem is yet to be found. This review describes the factors of fingermark variability and provides an extensive overview of various strategies implemented to control it. The use of artificial fingermarks or simulants, containing some of the most abundant compounds found in fingermark residue has been investigated by some research teams. However, most of these formulations are too simplistic and can only be used to assess a restrictive number of detection techniques, such as amino acid reagents. Practical applications of artificial fingermarks such as test strips and proficiency testing are reviewed. The advantage and challenges of using artificial fingermarks in the first stages of fingermark detection research are presented.

“…Goel 108 suggested the use of 1,2-indanedione-zinc chloride dry contact method over hot print system for the development of latent fingerprints on thermal paper as the former provides better-quality prints, which never fades with passage of time. Jasuja et al 109 suggested that pressure applied to deposit fingermarks and the donors sweat affect the quality of prints developed by ninhydrin method on white bond paper. Chen et al 110 suggested the use of ninhydrin and 1,2-indanedione to develop latent fingermarks on thermal papers.…”
