Inkscape logo tutorial: Woolmark logo
This Inkscape tutorial shows you how to use Inkscape to make a logo. Specifically, you will create a corporate logo using circular grids. We will be imitating the Woolmark logo, by Franco Grignani, from 1964. Grignani was a pioneer in incorporating optical illusion in graphic design. This logo exemplifies a clean, symmetrical design that is both interesting and timeless.
In this Inkscape tutorial, you will learn about:
- How to make a logo with grids
- Circular grids
- Boolean operations
- Optical illusion logo design
Let’s get started!
- Set the grid
- Create layers
- Create an equilateral triangle
First, create four layers using the Layers dialog (Layer > Layers). Name the layers, from bottom to top, like so: Triangle, Level 1, Level 2, Level 3. This will help us organize our work and deal with the complexity of the design as we move forward.
Create a grid for the document by going to View > Page Grid. Be sure to set the grid size (spacing) large enough so you can easily work with its scale.
Now, create an equilateral triangle, using the Stars and Polygons tool , by setting its corners to “3. ” Move the triangle to the Triangle layer by selecting Layer > Move Selection to Layer Above or Below, depending the layer on which the triangle was created.
Select the triangle, align its tip to a grid intersection and, pressing the SHIFT and CTRL keys *, enlarge (drag) the triangle so that its height is equal to an even number of squares (mine is 6 “grid squares” high). You may enable the snapping tool for more accuracy.
* The SHIFT key makes the object scale from its center of rotation, while the CTRL key makes it scale symmetrically.
- Create a perfect circle
- Duplicate and position circles
Locate the center of the triangle in terms of its height: In my case, it’s 6 “grid squares” high, so its center intersection lies on square 3. Position the cursor slightly upward off center, as shown. This will make our rendition more accurate in terms of the original logo.
Select the Circles tool. While pressing the SHIFT and CTRL keys, enlarge (drag) the circle so that it becomes a perfect circle. Make sure the edges of the circles touch the edges of the triangle.
Convert the circle to a path by selecting Path > Object to Path.
Duplicate the circle (CTRL + D keys or Edit > Duplicate). Move the duplicate to the lower left side. Press the CTRL key to drag the circle to the bottom, then press CTRL to drag to left, until it touches the left and bottom edges of the triangle.
Duplicate the lower left circle and drag to the right, using the CTRL key.
Now you have three cicles within a triangle.
- Duplicate upper left side circle
- Interpolate circles
- Move selection to layer above
We will now create the circles that will make up the black crescents of the design.
Select the lower left circle and, pressing the SHIFT key, also select the upper circle.
Go to Extensions > Generate from Path > Interpolate.
In the dialog, select “Duplicate endpaths” and be sure to set interpolation steps to 8. This is so because the extension will “fill” the space between the circles with duplicates of the same circles. If you look at the Woolmark logo, each side is composed of 10 circles.
The interpolated circles will be grouped, with a total of 10 objects. Select the group, then move the selection to the layer named “Level 1.” Turn off the layer (in the Layers dialog, click on the little eye icon to close it).
- Repeat process on step 3 for right side
Select the upper and lower circles by pressing the SHIFT key.
Repeat the interpolation process.
Move the selection to the layer named “Level 2” and turn off.
- Repeat process on steps 3 and 4 for bottom side
- Delete original circles
Select the lower right and left circles by pressing the SHIFT key.
Repeat the interpolation process.
Move the selection to the layer named “Level 3” and turn off.
Delete the three original guide circles before continuing with the next step.
- Apply the Boolean operation “Difference”
- Fill black, remove stroke to create crescents
Start with layer “Level 1”.
Turn on the layer and ungroup the interpolated circles by selecting them and pressing the CTRL and U keys. You now have 10 separate circle objects.
Create the crescents from the circular grid. Select the outermost circle and the circle that follows.
Apply Path > Difference. Apply black fill and remove stroke (Object > Fill and Stroke).
You now have your first crescent.
Repeat with all crescents of that side. You now should something that looks like this:
Turn off the layer and repeat with the remaining two sides:
- Use the eraser tool to clean paths
For the final step, turn on all layers.
Select the crescents whose tips protrude unto the opposite crescent set.
Select the Erase tool. At the top of the page, in Mode, select “Cut out from object.”
Start “erasing” the protruding crescent tips by passing the tool just to the contour of the opposite crescent. Be sure to remove all parts of the tip while the object is selected.
Repeat on all sides, according to the fold of the original Woolmark logo.
Turn off unnecessary layers.
You now have recreated a version of the Woolmark logo and learned about circular grids, Boolean operations, and logo design in the process.
