The enhancement in the visibility of the fingerprint marks with the CTF deposition cannot be contested, although the extent of the enhancement needs to be benchmarked against other techniques. While the features do get highly enhanced, it is also noted that at some places features may also be lost due to the overlapping and merging of the CTF ridges. This could be an effect of over-deposition of the CTF or it may also simply be due to small amounts of fingerprint debris leading to lowered levels of shadowing during the deposition. The exact thickness of the CTF deposition to maximize the visibility of the fingermarks needs to be optimized.
