Apparently, it is possible to change any scanned image into a blueline (you know...the blue outline that doesn't scan or copy) in PS 7. I have not been able to figure this out. Can someone please help me out? I'm working on a comic book and if this works, it will make my life a lot easier.

If you just convert from RGB to Indexed Color using the right shade of blue that would probably do it.
Make a custom swatch palette with your chosen shade of blue graduating to white and save it in your Presets as "Non-repro. Blues".
Then, when you do the conversion, choose "Custom" and load your saved "Non-repro. Blues" palette.

Ann's suggestion is probably much more efficient than mine, but the way I've done this is as follows:
Convert to grayscale
Convert back to cmyk (or rgb)
Add 2 layers above your artwork, both filled with the blue color. Set one of the color layers to "color"
Set the other color layer to "lighten"

Wouldn't a gradient map adjustment layer work as well and be a lot faster? No conversions just use your rgb image, pick the blue you want for shadow -done.

I appreciate the ideas, I will try them all and let you know what the results are.
thank you very much,

The Gradient Map way would leave color in all channels while the Indexed Color method makes a single one-color channel which can easily be used to make a Spot channel in an otherwise empty CMYK file.
If this is line-art, the indexed Color route might be better but it depends on how Kristina wants to use it.

Ann,
Would that be true for grey scale? Or Adj. layer desat. then map.

There's a lot of ways to do this, but I have to ask, how is it being printed? I know some people who use Kinkos (I think) and it's simply a matter of giving them a B&W document and telling them to copy it in non-photo blue.

Gray scale makes a single channel with no color content so a gradient map just maps in shades of gray. The single channel could be pasted into an empty CMYK file for use as a spot color channel.
Basically, anything that you do in the layers palette, whether with Effects or Adjustment Layers, throws information into all of the RGB or CMYK channels.

Okay. got it, Just went back and tried all the options-it finally soaked in.
