Yo!

I got my “Pilot Color Eno 0.7″ in the mail a few days ago. I ordered the “Soft Blue” one to do rough sketches with, before I attempt to ink the page with my other black pens (until now I’ve only inked my art on the computer, in ‘Easy Paint Tool SAI‘).
I just did a quick test with my scanner to see what happens when you scan a picture with only the blue lines and then another test with some black lines over the blue ones. I was glad to see it really worked and it seems like there’s basically two ways to do it…
You can choose to scan your art in “Black & White” mode, which will give you a picture with ONLY pure black and pure white pixels – in other words, NO anti-aliasing. If you zoom in on a picture like this, you’ll see that the lines are jagged because of the pixels, but I don’t know if this will be an issue when you print the final image (if you’ll notice it or not). This might depend on what resolution you scan your image with also. I did my test scan in 300 dpi, but unfortunately I’ve run out of ink in my printer, so I can’t see how it looks on paper. If you scan your art in 600 dpi the file size will be bigger, of course, but It might look better on paper.

Anyways, the second way of removing the blue lines from your artwork (I’m using Photoshop for this, by the way) is to open the window/tab called “Channels” and click on the one called “Blue”.
Now, I don’t know how this works, but this will remove all traces of blue in the image, leaving you with only the white background and black lineart (but with anti-aliasing). If you don’t have any black parts in the image then you’ll end up with a completely white image when you do this :p
You might have to play around with the “Levels” in the image to remove dirt or other small particles that you do not want there.

The Pilot Color Eno 0.7 (Soft Blue) seems to be a good mechanical pencil with lead that is a little on the soft side, but still okay. Sometimes when you draw with a ball pen over the pencil lines, the ink won’t stick and you might have to draw the same line again. However, it seems that when you use a felt pen, this won’t be as big of a problem. Maybe there’s a different type of ink in felt pens? Maybe it’s because they put out more ink at a time, I don’t know :/ But these were my first impressions when I did some quick tests with it.

Thanks for watching/reading, see ya next time!
