I've a couple of quick questions I'm hoping someone with experience can answer. On his website at
http://www.inkjetnegative.com/images/RNP/rnp.htm#The Big Picture,
Micheal Koch Schulte suggests that determining the best ink color to use for digital negatives is dependent on the light source used. You can see a big difference between UV and tungsten in his testing. What about differences between UV light sources themselves, he doesn't address it but is it an issue?
I use a 28V 1200 Mercury vapor lamp. If I am using piesography inks and their carbon curve (as I am) does their curve match my light source? It might if they used the same lamp but they don't say, is the difference great enough I need to worry about it?
From the little research I did, it looks like a few people looked into the RNP array method of making curves back in 2007-I saw Sandy King's post about where he tried it and didnt seem happy with it,but since no one as far as I can tell has really taken it up.
Its not proprietary, and seems to make sense. I had a difficult time unserstanding his direction for picking out the color to use for the negative, specifically his direction on picking a white square next to a black one, is anyone here using it to create curves? Any problems? Any successes?
Thanks for any thoughts..
Peter
