A more stable form of casting than 'play dough' is a silicone rubber mixture. Dentists use dental impression substances that may be your answer. You can mix up the material and apply it to the surface and wait for it set up and then remove it. I would do test areas on your pottery to see if it will release without damaging.
Another substance was invented by Kjell Carlsson in Sweden. It is called Mikosil and used in much the same way as dental impression material. Toolmark examiners use Mikosil to make reproductions of fine detail in toolmarks.
I would suggest you contact some of the outstanding examiners at your National Bureau of Investigation (NBI) Laboratory at Vantaa, there in Helsinki. I have a number of colleagues there and I am sure they can assist you in your project with their materials (keeping the expenses down!). One examiner at that location is Anja Ytti and her phone number at NHI is 8388 6383. Please pass on my regards if you make contact.
After you are able get a cast of the fingerprints (hopefully), you can use them to make an inked recording of the fingerprint. If the prints are impressed into the pottery, the cast will be have the 'ridges' in the same raised position as they are on the fingers. Inking the prints in the cast would be the same as inking a finger.
Good luck with your project and the fingerprint examiners at NBI may also be able to assist you.

Hello and greetings from Finland! Me and my fellow archaeology student here in the University of Helsinki are interested in fingerprints on ancient pottery. We are thinking about testing fingerprint comparison programs with the material, but we are having problems with extracting the fingerprints. Every piece of pottery is precious and important to future research so we can't use any destructive methods: everything that could leave a mark on the pottery is out of the question.
Maybe we could use some sort of soft playdough for molding? But what then; how do we get the fingerprint to a such a form that it can be easily transferred to the comparison program?
There is one other demand for the method: it has to be relatively cheap (have you ever seen an archaeology student with money?)! ;) It isn't that often in archaeology when you can 'get your hands on' an individual instead of a larger community; any help would be really appreciated.
