Tutorial: Illusion of transparency – Vector rays

In this tutorial we will create cool rays with gradients without using ANY transparency settings, ideal for .eps files, which do not have a support for gradient-on-gradient transparency. Here’s a preview of our final image.

  • Difficulty: Intermediate
  • Completion time: 15-30 minutes
  • Software: Adobe Illustrator 8 or higher – I use Illustrator CS3.

STEP 1

Grab the Polygon Tool (in the Rectangle Tool submenu) and draw a triangle – click-and-drag, then press the Down arrow to reduce the number of sides. Also hold the SHIFT key to place it into an orthogonal position. Set Fill to #000000 and no Stroke. Using the Selection Tool (V), rotate it 90 degrees clockwise.

Set its dimensions like below.

Hit OK. It should look like below. Select all rays and go to Object > Group (CTRL+G). Also give them another color.

Select only the rectangle and go to Object > Arrange > Send to back (CTRL+SHIFT+[ ). It should look like below. Place the square over the rays, select all and using the alignment tools (top side of your screen), hit the “Horizontal Align Center”.

STEP 9

Now click the “Vertical Align Center” button. Along with STEP 8, this will create a perfect alignment, so we don’t get any offsets further on.

If you want, you can add different motifs, stars, circles, different shapes and use the same technique to make them pop up. A fast, but not so precise method is to lighten the colors: click the “Recolor Artwork”, click the “Edit” button, then toggle the “Lock harmony colors” (broken chain icon) and move the slider a bit to the right.

In the source file I added a couple of examples of what you can do with this technique.

    I get as far as step 12 and when I apply the radial effect it does not look like the image provided. Help? Also, I cannot download the source file?
