Setting up your
document
|
In a new document, make sure the
options Snap to Point and Snap to Guides are turned
on in the View menu. Also make sure the measurement units
are set to Inches.
Next create 2 new layers and label
them like the example at right and make sure they are in the exact
order as you see them.
|
 |
| Next create a palette of the following
process colors. The values you need to enter for each of the named
colors (Red, Purple, etc.) are directly after the name. If you're
working in black and white, you only need the grays.
The base colors are Red, and
Purple. The Dark colors will be used for shadows.

Section
1: Drawing the Corner
 |
 |
|
1)
Create a 1 inch x 1 inch circle on the Foreground layer.
Check your inspector palette for the measurement. Ungroup
the circle and draw a line from the top point to the bottom point.
|
2)
While the line is still selected, Rotate only the line -45°
from it's center (the center point is automatically entered into
the Transform palette once you click on the line).
|
 |
|
3)
Now drag a horizontal guide and snap it to the top of the
circle. Drag a vertical guide and snap it to the right
side of the circle. Drag the zero point ruler guide (in
the upper left corner) to the intersecting guides (upper right
corner). Drag two more ruler guides to form a 2-inch square so
it looks like the above example.
Next draw a diagonal hairline and
send it to the Back Paper layer.
|
 |
|
4)
a: Now drag the circle+line straight left until the end
of the interior line butts up against the diagonal line (you want
this exact, so zoom in).
b: Clone the circle and line,
scale them 50% then align them the same way in the opposite corner
as shown above.
|
 |
|
5)
Now reposition the two ruler guides at the bottom and left to
the points highlighted in the above example.
|
 |
|
6)
Next, cut away three-quarters of each circle and delete it. This
can be easily done by selecting the top and right points of each
circle then choosing the Split command under the Modify
menu. Now using the Knife tool (make sure Close cut paths
is turned off) cut the remaining quarters in half at the diagonals
highlighted above.
|
 |
|
7)
Delete all the diagonal lines and send the two outermost curve
segments (highlighted in red for clarity) to the Back Paper
layer. Hide this layer for now.
|
 |
|
8)
With the Bezigon tool, click on the bottom of the top-left
curve piece, then continue with the 2nd and 3rd points labeled
above. Select all of the pieces and Join them. Now shift-click
on the points labeled A and B. In the inspector
palette, choose the Info tab and select the Connector point
type.
|
 |
|
9)
Now select the path, and in the Inspector palette, check closed.
Your shape should now look like the one above. Hide this layer
and make the Back Paper layer active.
|
 |
|
10)
Now using the same technique in step 8, connect the two
curve pieces like the above example. Close the path like step
9. Make sure the points labeled A and B are
Corner points. The points labeled C and D
should be Connector points.
|
 |
|
11)
Reveal the Foreground layer and you should see your page curl
pieces like the above example. Draw any size "sheet"
of paper on the Front Paper layer like above, and you have
all you need to draw a page curl. You can save this as a template
for later use.
|
Section
2: Shading the Curl
 |
|
1)
Now it's time to fill in the pieces. Fill the page curl White,
the Front paper Purple and the Back paper 20k. Set
all the lines to None (I've left them visible here for
clarity). If your illustration looks different than above, then
your layers might be in the wrong order. Check their order with
the example I have at the top of this page.
|
 |
|
2)
Create a rectangle and rotate it 45° and place it as shown.
Clone it and put it on the Background layer (you'll need
it later). Fill it graduated, from Purple to Dark Purple
at a 45° angle. Outlines are for clarity only.
|
 |
|
3)
Cut the graduated rectangle, select the Front Paper piece
and Paste inside. Now you've learned the basics of shading.
Always shade from a base color (here: 60c 100m) to the same color
plus black (60c 100m 60k).
|
 |
|
4)
Now draw a long rectangle as shown and fill it with red. Get that
angled box you hid in the Background layer and bring it
to your working layer. Fill it graduated, from Red to Dark
Red at a 45° angle. Outlines are for clarity only.
|
 |
|
4)
Cut the graduated rectangle, select the top Red bar piece and
Paste inside. Now doesn't that look cool? We're not done
yet.
|
 |
|
5)
Now we'll shade the Back Paper. Create a rectangle and rotate
it 45° and place it as shown making sure it hits the Back
Paper's leftmost corner (highlighted above). Fill it graduated,
from 60k to 20k at a 45° angle. Outlines
are for clarity only.
|
 |
|
6)
Cut the graduated rectangle, select the Back Paper piece
and Paste inside. Nearly there.
|
 |
|
7)
Now we'll fill in the flap. Create a rectangle, rotate it 45°,
clone it and enlarge it to look like the above example. Fill the
small rectangle graduated, from White to 20k at
a 45° angle. Fill the larger rectangle graduated, from 20k
to White at a 45° angle. Outlines are for clarity
only.
|
 |
|
8)
Cut the graduated rectangles, select the flap piece and
Paste inside.
|
 |
|
9)
Now we need to make the shadow that is cast by the flap
piece. Position a round-corner box as in the above example, then
fill it with Purple. Clone then scale the clone to fit
completely behind the curl, then fill it with Dark Purple.
Ungroup, then Blend the two shapes about 30-50 steps. Outlines
are for clarity only.
|
 |
|
10)
Cut the Blend, select the Front Paper piece and
Paste inside. There, you're all finished.
|
Of course you can play with all of these
techniques for various effects and paper styles. Just remember the shadow
rule: Base Color + Shadow color = Shadow. So if you have a Shadow
color that is 40k then you just add 40k to any Base colors that the
shadow falls over.
