Edit Colors and Distort Objects
• Illustrator provides a number of effects that
you can use to alter the shape of an object.
• The Pucker & Bloat effect adjusts the
segments between an object’s anchor points.

• The Bloat effect is achieved by moving the
segments outward and the anchor points

• The Twist effect rotates an object more
sharply in the center than it does at the edges,
creating a whirlpool effect.

Edit Colors and Distort Objects
• The Edit Colors commands on the Edit menu
are very useful for quickly applying color
changes to objects.
• The changes are applied directly to the
objects; they are not effects.
Edit Colors and Distort Objects
• You can saturate colors or desaturate colors in
an illustration.
• You can also use the Convert to Grayscale and
Blend Front to Back commands.

Work with Gradient Meshes
• The Mesh tool and the Create Gradient Mesh
command can be used to transform a basic
object into a mesh object.
• A mesh object is a single, multicolored object
in which colors can flow in different directions,
and colors transition gradually from point to
Work with Gradient Meshes
• When you create mesh objects, multiple mesh
lines crisscross the object.
• Mesh points are diamond-shaped and work
like anchor points.
– Can be assigned a color
– When assigned, color flows outward from point
Work with Gradient Meshes
• Area between
four mesh points
is a mesh patch.
• Apply color to all
four mesh points
by applying color
to patch.

Work with Gradient Meshes
• You can apply opacity settings to a mesh point
on a gradient mesh.
• Select one or more points on the mesh, then
drag the slider in the Transparency panel.
Work with Gradient Meshes
• Mesh points can be added, deleted, and
moved along mesh line without altering mesh
• Manipulate anchor points’ direction lines to
alter shape of mesh.
Work with Gradient Meshes
• The shape of the mesh is
manipulated by direction
• Mesh points can be
moved, just like anchor
Work with Gradient Meshes
• You can create a mesh object from any path.
• You cannot create a mesh from compound
paths or text objects.
• Use the Mesh tool or apply the Create
Gradient Mesh command.
Work with Gradient Meshes
• The Create Gradient Mesh command creates
a mesh object with regularly spaced mesh
lines and mesh points.

Work with Gradient Meshes
• Once you create a mesh object it can’t be
converted back.
• Complex mesh objects are a memory drain
and may effect computer performance.
– Better to create a few simple mesh objects rather
then a single complex one

Work with Envelopes
• Envelopes are objects used to distort selected
• Objects take on shape of envelope object.
Work with Envelopes
• Make envelopes with:
• Objects you create
• Preset wrap shapes
• Mesh objects
• Use envelopes with compound paths, text
objects, meshes, and blends.

• Create envelopes with top objects, meshes,
and wraps.
• Create an envelope by using the Envelope

Create Blends
• A blend is a series of intermediate objects and
colors between two or more selected objects.
Create Blends
• Blends are created with:
– Blending tool or
– Make Blend command
Create Blends
• Make blends between:
– two open paths
– two closed paths
– objects filled with gradients
– blends
Create Blends
• The fewer the number of steps in a blend, the
more distinct each object will be.
• A large number of steps creates the illusion of
being continuous or “smooth.”
Create Blends
• In Blend Options dialog box select
– Specified Steps
– Specified Distance
– Smooth Color – default option
Create Blends
• You can create a

• You can create
color effects with a
blend and a mask.

You can apply blends to paths.
Create Blends
• Affect the appearance of a blend by
manipulating its spine.
• When blend created, path is drawn between
starting and ending objects – referred to as
spine and manipulated like a path.
Create Blends
• Examples:
– Add anchor points to spine with Pen tool, then
move them with Direct Selection tool
– Spine can be replaced by drawing a path with Pen
tool, then select it along with any blend and apply
the Replace Spine command
