Most anyone who has been shoveling on this sandpile for more that a couple of minutes knows my attitude towards excessive reverence of profiles and profiling in general. That notwithstanding I use a single, as in one, profile for 99% of everything I print on all manner of vinyl, canvas, and banners. It started out life as Oracal's 3651G profile in which I changed the rendering intents and jacked up the algorithms for dither and gradients. It suits my needs just fine and no client has ever complained in any way about the quality of the print.
