Yes it's positive. This is the first step toward duplicating negatives. But getting the contrast right requires some work; you will probably want to contact print onto ilford ortho plus, develop your positive by inspection in a fairly contrasty developer, and perhaps selenium tone the positive to build up a bit more density if you need it. If you do some test strips you'll get it right. Tmax is also a good film for this enterprise but then you can't develop by inspection. O+ and tmax have nice backings so you do get reasonably good, viewable positives with little or no loss in resolution.
There are other ways to do this... but working with o+ is pretty easy since you can work with a red safelight. It's pretty easy to get a washed out positive though, that's what takes some work.
