A few years ago, in our lab a BS student did a study concerning the optimalisation of the fluoresceïn- reagent. As a part of it, I made for her a latex replica of my index finger, so she got a “standard” finger to create “bloody” latent prints on various surfaces with different dilutions of blood. Given the water-based dilutions, it was not always possible tot get a clear print.
I guess you can do it the same way by using a ( quick drying alcohol-based ?) standard oily / amino-acids mixture.
Good luck anyway.

Then it would not be a "fingerprint". Perhaps you could do research on the chemical enhancement of rubber stamps.

I am not a fingerprint expert but i am doig a PhD in the chemical enhancement of fingeprints. My question is does anyone know of any research that has been conducted using a rubber stamp fingerprint impression as a sample rather than real fingerprints.
I am looking at doing this because of the subjectivity when comparing fingerprint samples purposely laid for research analysis.
I am hoping that this will help me be able to directly compare reagents and clarity knowing that all fingerprints laid for the research are exactly the same.
