All invisible friction ridge skin impressions (not visible before processing, special illumination, electronic detection, etc.) are considered latent prints... however, not all latent prints are invisible.
The SWGFAST glossary definitions are as follows:
LATENT PRINT - Transferred impression of friction ridge detail not readily visible; generic term used for questioned friction ridge detail.
PATENT PRINT - Friction ridge impression of unknown origin, visible without development.

I would not disagree with Andrew but here is my take on your question:
Any impression of friction ridge skin on any substrate can be considered a latent print. (From the Latin "LATERE" meaning in hiding or generally to that effect.
A latent print can sometimes be visible. (depending on the qualities of the substrate on which and the matrix with which it was made.)
A latent print will mostly be invisble at the first inspection and so, to answer your question it is not always possible to draw a clear distinction between latent and invisible prints.

There are three basic types of fingerprints, latent- which means that the print is invisible and needs either physical (e.g. fingerprint powder) or chemical (e.g. SG Fuming) to become visible; patent- which means that the print is visible due to the matrix of the print (i.e. left in blood, mud, ink); and plastic- which is an impressed print, such as left in clay or silly putty. Hope that helps.
