Re: outdoor gum demo
Oh, come on!!?? My understanding of the discussion was that yellow "ink" is the most opaque to UV light compared to other colored "ink"s (there wasn't named a single inkset which doesn't exhibit this - BTW, black is another case and I won't get there...), but it is not necessarily more opaque than combination "colors" (mostly; Mark told about R1800 where yellow "ink" is the most opaque including combination "color"s in the comparison...) for whatever reason (probably because there's more ink on a given area then when printing with a single ink). And all above was given in the context of many different inksets! Most importantly, being highly sensitive to sunlight, I happen to burn more under say red, blue, white beach umbrellas compared to yellow ones -> empirical evidence to me, bringing us to my original suggestion of a yellow tent... 16 Nisan 2009, Perşembe, 2:09 am tarihinde, Katharine Thayer yazmış: > > ... > > Forget the yellow tent.
