Anybody scene an interesting way to make a blackilight poster?

I've never done a blacklight from digital, so you can ignore this if you like. It seems to me, that you'd have to do a "layer from original", and remove everything but what you want highlighted. the printing would be a two-step process... first would be the normal print, then the "glow" ink would be applied. If you want to do the whole thing in Flourescent inks, they are available, though I don't have any info on specifics. One thing, "Day Glo" paints work very well in this medium, but they would have to be hand applied. Lou.

Not sure if this is what you';re looking for...

You could scan a blacklight poster or two. then using the eyedropper capture the colors of the fluorescent inks and make your own palette. Only thing I can think of.

I'm thinking really complicated. Something to the effect of changing Color Modes.

Are we talking psychodelic style black light?

Yep?

This is the scientific explanation for the effect: Quoted: "Many kinds of color phenomena (particularly in gems and metals) arise because the incident light is absorbed by atoms, and this disturbs the electrons in various ways that create the apparent color. fluorescence arises in natural materials for several different reasons. In the case of fluorescent paints and inks, the incident light disturbs the atom sufficiently to cause it to emit a photon in response, usually at a different wavelength than the light absorbed. At the same time, the paints or inks absorb or reflect light in the way normal paints do. the "fluorescent" effect arises in the wavelengths that are emitted from the atom, rather than reflected, causing the "glowing" effect." Bottom line is that in order to get the effect that you want you will need the proper ink or paint because the paint is actually emitting light. The next best approximation is as bonestructure suggested. The following link will allow you to obtain the RGB colour values of fluorescent paint with the eyedropper. http://www.goldenpaints.com/products/color/unique/fluor.php Shane

I see where knowing which inks to use are important, but then somehow we will need to build another Color Mode though, which is currently beyond my scope of knowledge, as Color Modes either do, or do not, have millions and millions of Colors. My best guess would be to try and figure out wich of the current RGB(Billions of Colors?) colors would pass as Flourescent, and then Map the rest to the nearest relative. Having those inks ready to try an print with would be great if they came with a Color Mode to acuratelyy preview what it is you're printing. Unless you're trying to print more of a Illustration than a photo or render, as I am.

You dont mean psychedelic like taking the image on the left and converting it to the image on the right, do you?

If so VM plugins has a vm psychedelic filter in the vm extravaganza toolbox:

Grafnet used to create the above effect from an image I created using Illustrator.

BTW, you should check all these plugins out. You have many useful ones here like vm natural has lightburst, raygun and splash which can be used to create streaming rays of light cutting across your images.

Good work Quest! I'm a liilte confused, where are the filters available for DL? I'd love to see that filter on a real photo! = )

Oh, I'm sorry, I see that it's disabled (grayed out). Anyway, a google search for "vm extravaganza" brings up this site and I've checked that the download is active, you can also download the others from here also. Just scroll down to the v-w section. Give this one a try. Let me know if it doesn't work for you.
