I sketch the rough draft for the storyboard.
At this point, if you can imagine the page layout with lights, darks, solid colors, and saturated lines, the rest of the creation process should progress smoothly.

[1] Drawing frame overlapping line art

(1) I will now sketch the rough draft on the 4th frame where the character and frame border overlap.
For layers inside the frame border folder, it will mask any lines outside the frame border. Therefore, I will create a new layer outside (above) the folder.

I will draw the rough draft of the 4th frame on this layer so parts of the character can be drawn outside the frame.

(2) I will draw the rough layer for 1st, 2nd, and 3rd frames by creating a new layer in the [Frame border folder].

[2] Work process of overlapping elements

To be able to make corrections to the part of the character that overlaps the frame, I create a fill layer.

(1) I create a rough selection using the [Rectangle selection] sub tool.

(2) Then, I select [Layer] menu > [New Layer] > [Fill].

(3) I pick a color from the displayed [Color settings] dialog box.
I chose a dark pink color to make it easier to see the areas I paint.

(4) I place the fill layer on the top of the [layer] palette directly under the “Overlapping line art” layer.

(5) Then, I create a selection using the [Auto select] tool > [Refer to all layers] sub tool.
In the [Tool property] palette of the [Refer to all layers] sub tool, you can set the “overlapping line art” layer's line art to reference the drawing above it.

When using [Selection], work with [Anti-aliasing] unchecked.
When [Anti-aliasing] is enabled, you may select things you don’t intend to select.

(6) I select the outside part of the character with the [Auto Selection] tool.
Above the solid fill layer, I click the outside part of the character coming out of the frame.

(7) I click [delete] on the selection launcher to erase any unneeded parts of the solid color.
Note: To edit a solid fill layer, select the mask on the [Layers] palette and then begin editing it.

I deleted the unneeded parts of the solid color.

(8) Next, I change the layer’s color from dark pink to white.
As I did in the storyboarding process, I change the [Layer color] setting in the [Layer Properties] palette to white.
This creates a white fill layer behind the character, and with the lower layer hierarchy, I can now hide the overlapping frame lines of the picture.

This completes the process of erasing elements where the frame and character overlap.

[3] Making solid black fill on vector layers

I add a black solid fill to the 4th frame.
Although it is common to add solid black fills after inking, I will go ahead and add the black solid fill at this point to consider how to process the background.

I create a selection area where I want the solid black fill to be, and then select the [Layer] menu > [Create New Layer] > [Fill] layer.

I place the fill layer as the lowest layer in the [Frame border folder].

With this, the solid fill work is completed. Next time, I will add a flash and saturated lines to the rough draft.
