Making layers is easier then you think. Here’s a simple process that I do. There are many different ways of doing this and no one way is the right way, they all are.
1. After you’ve scanned, trimmed, scaled and tidied your line work, you need
to select the page and copy it. But before make sure it’s been converted to
CMYK or RGB mode so you can apply layers and take advantage of
Image>Mode>CMYK or RGB
Now we copy the file.
3. Now go to the channels tab in the layers window. There should be 4
channels if you chose CMYK or 3 if you went for RGB. Now we’ll make a
new channel. Click the small down arrow in top corner of layers window.
Select new channel and name it lineart, inks or whatever you want. A new
channel should now appear in the channels tab. Now we’ll paste the
lineart on to this channel.
Now click on the CMYK/RGB channel at the top and return to layers by
clicking layers tab.
4. Now select all and clear the image. Don’t panic, it’ll be back!
5. Now we’ll load the art as a selection.
A window should open with a selection named lineart, inks or whatever
you named it in the channels list. Select OK.
Your image should appear as dots or marching ants.
6. Now we’ll fill this with a light colour. Select a light blue from the colour
swatches. Now click on the paint bucket tool in the tools window. Set the
tolerance to 255 so it fills everything. Click the paint bucket inside the art.
Your image should now appear in light blue.
7. Whilst the image is still selected we’ll create a new layer where your black
linework will appear.
Click on the layers menu and create a new layer as you did a new
channel. Name the new layer Linework, inks or whatever.
Now pick the colour black from the colour swatch and again click
the paint bucket inside the artwork. Your art should now appear
as black inks.
Now deselect the art.
Return you paint bucket tolerance back to 111.
8. Save your file.
9. You can now colour on the background layer without affecting your black
& white linework. If you’d prefer, as I do, to remove the blue line
from the background layer then simply clear it or use the eraser tool to
I hope you find these two posts helpful, now get drawing!
