Durability of Dark vs Light Prints

[megafonico]

Hello Sign Gang,

I will be replacing some five or six signs for a Medical Office on the next couple of weeks.
This will be printed by EcoSolvent on ORAJET 3165RA and laminated using ORAGUARD 210.

The signs are all facing west so they will get a fair amount of sunlight from noon to sunset.

From a pure durability point of view and everything else been equal, we are trying to decide if we should to White logos/lettering on black background or Black logos/lettering on white background.

I appreciate all input.

If it's really white on black or black on white, and UV durability is the concern, use cut high performance vinyl, not a print. Even as the vinyl dies, the sign will read better than a print that is dying.

Durability is not the main concern and their logos do not lend very well to cut vinyl.
They are prepared to replace signs after a few years, but if they will be extending the life of the print by going with one color combination over the other they will gladly do so.

It really isn't going to make any difference in durability whether it's black on white or reversed.
