Like with solid fills, flashes and saturated lines are normally drawn after the inking the rough draft, but I want to see how it looks now.
Editing hand-drawn manga is difficult if you don’t follow a certain drawing procedure, but with digital manga, it’s alright to switch steps around as you can easily edit anything at any time.
A. Positioning the flash material
(1) I place the flash on the background of the fourth frame.
First, I change the [Layer color] in the [Layer Properties] palette from black to blue.
(2) Next, I select [Effect line] from the [Material] palette > [Manga material].
The I select [Beta flash 01] and drag and drop it onto the comic page.
(3) I edit the pasted tone using the [Object] sub tool.
(4) I drag the light blue square to scale down to the right size.
(5) I create the first frame balloon by customizing the [Sea urchin flash] sub tool. You can use [Sea urchin flash] from the [Flash] sub tool group under the [Balloon] tool.
Note: For details on setting and using the [Flash] tool, see  in the following article.
(6) I change the text color to white with [Layer color] in the [Layer Properties] palette.
Materials in the [Material] palette are not regular raster layers. They are [image material] layers. [Image material] layers cannot be edited by drawing on it with the pen tool or erasing with the eraser tool.
If you wish to edit a material, you can use a [Layer Mask] or rasterize it by clicking [Rasterize] in the [Layer] Menu and editing it from there.
Note: Read the following TIPS article to learn how to use layer masks.
B. Inserting a saturated line
I insert a saturated line in the third panel.
(1) Just like in the solid filling procedure, enclose the area you want to place a concentration line with the [Selection] tool's [Polyline] tool.
(2) I then select [Figure] tool > [Saturated line] group > [Scattered saturated line].
(3) I draw the lines by clicking and dragging on the canvas.
This creates a layer mask of the selection automatically.
(4) I then adjust the saturated line’s size and position, using the [Object] sub tool.
C. Changing the line art color
With the rough draft finished, I will change its color to light blue before proceeding with inking.
Since there are a number of layers whose colors I wish to change, I move them all to a layer folder so I can change them all at once.
(1) I create a layer folder inside the “Frame border folder” and put in all the layers that I want to change the color. Then I apply a [Layer color] from the [Layer Property] palette. I changed them to a light blue color.
(2) With changing all of the layers outside the frame border’s [Layer Property] to light blue, the rough draft is complete.
Next time, I’ll ink the background.
