Adobe Illustrator tutorial: clipping mask and compound path
Aloha, designers! Please meet Community Director, Jason Aiken’s sweet and totally-cute dogs, Job and Lily.
Job and Lily have a love for professional swimming and we are going to use one of Illustrator’s brilliant design tools to show off their skills — the clipping mask.
What is a Clipping Mask?
A clipping mask is a shape (called a clipping path) that masks any object below it, so only what’s inside of the clipping path is visible. A clipping path can only be a vector object, not a photo. However, the object below it can be anything – a raster photo, vector drawing, etc.
A few things to note about clipping masks:
- The clipping path must always be on top of the object you’d like to clip.
- You can only have one clipping path.
- However, one or more objects can be clipped.
- Clipped objects must be in the same layer or group.
By now you might be thinking… “What? I’m a visual learner.” Well I am too… so let’s demonstrate.
How to Make a Clipping Mask
In this demo, the clipping path will be the text of their names, Lily and Job. The objects we are going to clip will be images of them swimming. To start, we will do a clipping mask for Job.
A clipping mask can be made in a few different ways:
- Drop down Menu: Object > Clipping Mask > Make
- Shortcut Key: Command > 7
- Layer Panel: Make/Release Clipping Mask icon at the bottom
- Right click: highlight all objects and select Make Clipping Mask
In one layer, I have put Job’s name on top of his swimming photo. You can expand the layer view to see the text and object image separately:
Note: you can use different layers, as long as the clipping path layer is on top of the photo layer.
Once the images are properly arranged, click on Object > Clipping Mask > Make. You will notice that everything disappears except what is inside of the clipping path (Job’s name).
Cool and easy, huh?
If done correctly, incorporating photos into words can be cool for posters and book covers (or tutorials ;).
Using Two or More Clipping Paths
Now, let’s do the same thing for Lily. Lily’s name needs to be altered so that her image fits nicely. When dealing with clipping masks, you will often find that either the clipping path or object underneath needs to be altered to fit together.
In this case, I want to edit the letters individually. First, I converted the text to outline so each letter can be edited. To convert text to outlines, click on Type > Create Outlines (shift>command>O) or by right clicking on the text and selecting Create Outlines.
Each letter has now become an object that can be edited but not like regular text. You will notice that anchor points appear on each letter — they can be moved and edited individually:
The outlined text is no longer one path (it’s now four paths: L I L Y). It will not clip correctly because remember, you can only have one clipping path.
Luckily, compound path allows several paths to be combined into one path. We can convert it to one path by highlighting Lily and selecting Object > Compound Path > Make (Command>8).
Now, highlight the compound path and photo, then select Object > Clipping Mask > Make:
Voilà! Lily is having some fun.
As you saw, compound paths combine all selected paths into one. You can also use this tool to make some pretty cool designs quickly.
Play around with it by taking a few basic shapes and stacking them on top of each other. Then select Object > Compound Path > Make (Command>8):
This is three compound paths but each compound path has multiple shapes incorporated into it.
Clipping Two or More Objects
Although, there can not be two or more clipping paths (without making them a compound path), you CAN clip two or more objects underneath.
I’ve made sure the photos of Lily and Job are on the same layer. I’ve also made sure they are placed underneath the clipping path: DOG LOVE.
Select Object > Clipping Mask > Make. I’ve made the images more visible by adding a black background.
Release or Edit a Clipping Mask and Compound Path
To release or edit a clipping mask, you can either:
- Select Object > Clipping Mask > Edit/Release
- Or edit by isolating the clipping mask: double click it or find it on the Layers Panel
Release or edit a compound path:
- Select Object > Compound Path > Release
- Or edit by isolating the compound path: double click it or find it on the Layers Panel
As you can see, clipping masks and compound paths are some pretty cool and easy tools that make designing that much more fun.
Thanks to Job and Lily for showing the community just how fun the clipping mask can be:
Note: The clipping path is JOB LILY and it’s clipping the graphic, THANKS.
