Illustrator’s built in Symbol Sprayer can be a highly useful tool for quickly creating awesome pattern graphics. Let’s look at creating a few vector skull graphics, then combine them into an intricate pattern design to customise a skateboard deck.
We’ll be using our design to create a custom skate deck graphic, but it doesn’t have to stop there. This technique can come in handy for any design project.
Open up Adobe Illustrator and draw a circle onto the artboard. Hold Shift to constrain the proportions.
Draw a Rounded Rectangle onto the artboard, alter the radius of the corners by pressing the cursor keys. Overlap the rectangle with the circle and Align along the vertical axis using the Align Palette.
Combine the two shapes using the Add to Shape Area option from the Pathfinder palette.
Adjust the stroke of the new shape to add a thick black outline.
Draw a circle filled with black, then duplicate it to the side. Group the two circles then align them centrally with the overall skull outline.
Grab the Star tool and click and drag a shape onto the artboard. Before releasing the mouse, press the downward cursor key to limit the points to three, creating a triangle.
Go to Effect > Stylize > Round Corners, enter a figure of around 10mm to round off the pointed edges.
Scale and position the triangle as a nose on the skull.
Use the Rounded Rectangle to create a long thin shape. Copy (CMD+C) and paste in place (CMD+F), then move to one side while holding Shift.
With the two shapes selected, go to Object > Blend > Make. Go back and adjust the Blend Options under the Object menu to give three specified steps. Go to Object > Expand and select just the Object checkbox.
Duplicate the skull outline and send it to the top of the stack (CMD+Shift+]). Temporarily fill it with a random colour. Ungroup the collection of rectangles, then go to Object > Compound Path > Make. Select both the new skull outline and set of rectangles and use the third option from the Pathfinder palette to trim out the excess.
Repeat the last few stages to create a set of three skull graphics, each with slightly different proportions to add a little variety to the pattern.
Select each graphic individually and click the New Symbol icon from the Symbols palette.
Grab the Symbol Sprayer tool and select the first skull graphic from the Symbols palette. Click and drag across the artboard to place the first few instances of the graphic.
Click and hold the Symbol Sprayer icon to reveal the secondary tools. Double click the Symbol Rotator to adjust the settings. Change the Method to Random.
Use the Symbol Sprayer Rotator to spin the skulls in various directions, creating a purely random layout.
Select the Symbol Sizer tool and change the Method to Random. Then use the tool to add a variety of sizes to the symbols.
Select the next skull symbol in the palette and go back to the basic sprayer to add more graphics to the design.
Repeat the process of rotating and scaling each set of symbols, then move onto the next skull.
In no time the artboard will be packed full of random skulls. Keep alternating between the symbols until all gaps are filled.
Manually drag a symbol onto the design to fill specific areas.
Zoom out and check over the design for balance, ensuring no areas have a bunch of larger skulls or a collection of graphics facing the same direction.
Position individual skulls onto the design to balance out the pattern with large graphics evenly spaced.
Select all and group the skull symbols. Use the Rounded Rectangle tool to draw a shape simulating a skate deck to ensure a large enough area is covered.
Paste in your design to create a realistic mockup of your skate deck graphic.
The final design uses just the three skull illustrations, but thanks to the Symbol Sprayer, a cool pattern can be quickly created. The result is an awesome deck design!
