Creating a gradient opacity mask in Illustrator

by

Illustrator has great control over gradients and blends but if you want to fade the gradient from color to transparency you have to use Opacity Mask.

The use of opacity masks in Illustrator is not as straightforward as in Photoshop but is just as powerful once you get to know how to use them.

Here is something to get you started.

 

THE PROCESS

Select the object you want to make transparent. Create a rectangle and fill it with black and white gradient. 

(The gradient you use as a mask doesn´t have to be black and white, you can use any color you like).

Make sure the gradient is in front of the object you are working on. And Select both objects.

Now open the Transparency panel and choose “Make Opacity Mask”

make_opacity_mask

The lighter color of the gradient makes the object transparent and dark makes it opaque.

gm_04If you click on the gradient icon in the Transparency panel, you can play around with the gradient on the artboard, changing the direction and position of the gradient.

Clicking back on the object icon takes you back to the object where you can change it´s color and apply effects.

You can even fill it with a gradient.

    I am having a small problem with this -
    Because my background is black, it creates a certain ‘fade to white’.
    IMHO it only makes the perfect white transparent, and the grey’s become only half transparent.
    Have you stumbled upon this problem?

  5. Chad Bruce Says:

    This was exactly the solution I was seeking! The Illustrator CS3 book I was using mentioned nothing of the “Make Opacity Mask” option tucked away in the drop-down menu of the transparency panel.

    Hello! I just wanted to ask if you ever have any problems with
    hackers? My last blog (wordpress) was hacked and I ended up losing several weeks of hard work due to no back up.

    Do you have any solutions to protect against hackers?

  11. resources Says:

    Howdy, i read your blog occasionally and i own a similar one and i was just wondering
    if you get a lot of spam feedback? If so how do you protect against it, any plugin or
    anything you can recommend? I get so much lately it’s driving me mad so any support is very much appreciated.

    Today, I went to the beach front with my kids.

    I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her
    ear and screamed. There was a hermit crab inside and it pinched her ear.
    She never wants to go back! LoL I know this is totally off topic but I had
    to tell someone!
