Pet peeve: The non photo blue will be picked up by scanners. It can be easily removed with a few adjustments on the computer, but it will still be there. Contrary to the statement of: "Instead of using graphite, you can use the non-photo blue pencil which is undetectable by copiers and computers allowing you to easily scan inked sketches."
I use non-photo blue a fair amount. It does not magically vanish when I scan, I have to remove it. It is, however, a very simple colour to remove, and works well under the Staedtler pigment liners. It is super useful and I do not want to discourage its use. :D Just keep this in mind when scanning, you will have to use software to clean it up a little.

snowbringerActually, if you scan in black and white mode (NOT grayscale), non-photo is usually not picked up by scanners since it's so pale. I've been doing that for a couple years now, and it's been working fine for me. Obviously though, this means the part of your picture you want to keep has to be black (or pretty dark at least) and of an even color, otherwise it's gonna disappear in some places (so ink is good; pencil, not so much).

BlueberryBearMy scanner picks up non photo blue in black and white. :P You can adjust levels and such to make it go away, but I am picky. ;)

snowbringerThat's strange. I've tested it with a couple of scanners, and it worked fine without any adjustment for me. Guess it probably depends of how each scanner works. ;)
