Tone Of What?
I'm a great admirer of the recent Lurpak advertising. Perhaps that's why I scrutinise it more closely than the usual dross. Thus it was that I noticed a jarring mix of language in this poster.
On the one hand you have the portentous "Venture Forth, on the other the more than mundane "Cooking Liquid". You can debate whether either is the appropriate tone of voice with which to address the customer, but the dissonance is striking.
For me, the product name is the weak link. Redolent of brake fluid, it's functional naming taken a step too far - all the more so as it's meant to be an innovation. In light of the excellence of the other executions, I'm probably being over-fussy, but a lot of lip-service is paid to consistency of voice and it's particularly obvious when you see it in print.
