5. Applying Fills, Strokes, and Gradients

Introduction

The Stroke panel makes it easy to change stroke attributes, such as weight (width), position on the path, and its style. The weight of a stroke refers to the thickness of the line. The Eyedropper tool on the Tools panel is another way you can quickly pick up an object’s color and stroke attributes and apply them to another object. Instead of using a solid color as an object fill, you can create and use patterns. The process is very simple. In Illustrator, create a pattern using drawing tools, select and drag the object pattern to the Swatches panel, and then give it a name.

A blend uses two or more objects to create a transitional object in between. If you’re just getting start with blends, the Make command on the Blend submenu is an easy way to create a blend. All you need to do is select the objects that you want to use, and then choose the command. That’s it. If you want a little more control over the way a blend turns out, you can specify options in the Blend Options dialog box. If you want to specify the locations where the blend takes place, you can use the Blend tool. Transparency, or the opacity level of an object, is set in Illustrator by adjusting the Opacity option in the Transparency or Control panels. Along with the Opacity option is the blending mode, which blends colors together for objects in a group as well as all the objects below it.

A gradient is a smooth transition between two or more colors in an object. You can apply one of Illustrator’s built-in gradients or create one of your own by using the Gradient panel. There are two types of gradients: Radial (circular) and Linear (horizontal). With the Gradient tool, you can edit gradient colors applied to the object by adding or changing color stops, applying transparency, and changing gradient direction (linear) or angle (radial).

Applying Fill and Stroke Colors

image

IL 3.2, 5.4

The Tools panel provides color boxes to make it easy for you to apply fill and stroke colors. The color box in the foreground is the Fill box and the outlined box in the background is the Stroke box. When you select an object, fill, or stroke, the color boxes (also known as thumbnails), on the Tools panel display the current colors. To change the fill or stroke color, select an object, fill or stroke, select the Fill or Stroke box, and then select a color from the Color, Swatches, or Color Guide panel., or use the Eyedropper to apply a color from the active document.

Changing Stroke Attributes

image

IL 2.2

The Stroke panel makes it easy to change stroke attributes, such as weight (width), position on the path, and its style. The weight of a stroke represents the thickness of the line. A weight smaller than.25 may not print and a weight of 0 removes the stroke. In addition to the width of a stroke, you can also specify the position (known as alignment) of the stroke on the path (either center, inside, or outside). Style is what stands out on the page. You can change the stroke style by applying dashes and sharpening or rounding corners and endpoints.

image

Using the Eyedropper Tool

image

IL 5.4

The Eyedropper tool on the Tools panel makes it easy to quickly pick up a color from one area of your artwork and apply it to another area. When you click an object with the Eyedropper tool, it picks up the object’s color and stroke attributes and displays them in the Tools, Color, and Stroke panels. You can pick up attributes from any type of object, even a graphic image and the object doesn’t need to be selected. If an object is selected, the color and stroke attributes are applied to the selected object. The Eyedropper tool also provides options for you to customize the attributes—such as Appearance, Transparency, Focal Fill and Focal Stroke, Character Style and Paragraph Style—that you want to pick up with the tool.

Apply Colors and Attributes with the Eyedropper Tool

image If you want to apply the pick up color and attributes to one or more objects, then select them.

image

image Select the Eyedropper tool on the Tools panel.

image

image Click an object in any window that contains the color and attributes that you want to pick up and apply.

image If you want to apply color attributes from the currently selected object and apply them to another object you select, Alt+click (Win) or Option+click (Mac) the objects.

image To have the Eyedropper tool only pick up an object’s color and not other attributes, click the Fill or Stroke box on the Tools or Color panel, and then Shift+click the color to be picked up.

image

Change Eyedropper Options

image Double-click the Eyedropper tool on the Tools panel.

image In the left column, select the check boxes for the options that you want the Eyedropper to pick up and deselect the ones you don’t.

image Click the Raster Sample Size list arrow, and then select a sample size for the pick up color and attributes.

image Click OK.

image

Using Patterns as Fills

image

IL 2.10

Instead of using solid color or gradients as object fills, you can also create and use patterns. The process is very simple. In Illustrator, create a pattern using tools—such as Rectangle, Ellipse, Polygon, Arc, Spiral, Star, or Flare—on the Tools panel, select and drag it to the Swatches panel, and then give it a name. The pattern consists of a group of objects, which you can also edit using Isolation Mode.

Create a Pattern and Apply it to an Object

image Draw one or more objects to be used as a pattern.

image Select the Selection tool on the Tools panel.

image

image Select all the objects.

image

image Click the Edit menu, and then click Define Pattern.

image You can also drag the selection to the Swatches panel, deselect the objects, and then double-click the new swatch.

image Type a name for the swatch.

image Click OK.

image

image To use the pattern as a fill, select an object, select the Swatches panel with the pattern, click the Fill box on the Tools panel, and then click the pattern in the Swatches panel.

image

Did You Know?

You can reposition a pattern fill. To reposition the pattern fill or stroke in an object without moving the object, select the Selection tool, hold down ~ (tilde) and drag inside the object.

Edit a Pattern

image Select the Swatches panel with the pattern that you want to edit.

image

image Drag the pattern to an empty area on an artboard.

image Double-click the object to enter Isolation Mode.

image With the Direct Selection tool, edit individual objects in the pattern, and then click the gray bar to exit Isolation Mode.

image

image Select the Selection tool on the Tools panel.

image

image Alt+drag (Win) or Option+drag (Mac) the pattern object on the artboard to the original pattern in the Swatches panel to override it.

image

Did You Know?

You can expand a pattern into individual objects. Select the object with the pattern, click the Object menu, click Expand, select the Fill check box and/or the Stroke check box, and then click OK.

Blending Fill Colors

The Edit Color submenu allows you to blend fill colors for three or more objects. The more objects that you select, the more gradual the color blend. Stroke colors and attributes remain the same. Illustrator takes the objects on the edges (front and back, left and right, and top and bottom) as the starting and ending colors in the blend. All objects in between the starting and ending ones are intermediate blends.

Blend Fill Colors

image Select three or more objects that contain fill colors.

image The objects cannot contain global process colors, patterns, or gradients.

image

image Click the Edit menu, and then point to Edit Colors.

image Select any of the following commands:

image Blend Front to Back. Uses the fill color of the front and back objects in the selection as the starting and ending colors in the blend.

image Blend Horizontally. Uses the fill color of the left side and right side objects as the starting and ending colors in the blend.

image Blend Vertically. Uses the fill color of the top and bottom objects as the starting and ending colors in the blend.

image
image

Creating Blends Automatically

If you’re just getting started with blends, the Make command on the Blend submenu is an easy way to create a blend. All you need to do is select the objects that you want to use in the blend, and then choose the Make command. That’s it. Illustrator creates all the transitional objects in between. If you don’t like the results, you can undo the blend and try something else. If you no longer want the blend, you can release it, which removes the transitional objects and leaves the original objects and the path.

Make and Release Blend Objects

image Select two or more objects or groups (with space in between them) that you want to blend.

image

image Click the Object menu, point to Blend, and then click Make.

image To undo the creation of the blend objects, click the Edit menu, and then click Undo.

image Select the blend objects.

image

image To release the blend objects, click the Object menu, point to Blend, and then click Release.

image The transitional objects between the original objects are removed, while the original objects and path remain intact.

Applying Blend Options

If you want a little more control over the way a blend turns out, you can specify options in the Blend Options dialog box. The settings automatically apply to any selected objects and future blends. The settings include Smooth Color, Specified Steps (number of transitional steps), Specified Distance, Align to Page, and Align to Path. The Preview option allows you to view your changes on the screen as you make them.

Change and Apply Blend Options

image Select an existing blend object.

image Click the Object menu, point to Blend, and then click Blend Options.

image Select the Preview check box to view your changes.

image Click the Spacing list arrow, and then select one of the following:

image Smooth Color. Select to automatically create a smooth color blend based on the number of transitional steps needed.

image Specified Steps. Enter the number of transitional steps (1-1000) that you want.

image Specified Distance. Enter the distance (.1-1000 points) between the transition objects in the blend.

image Select one of the following orientation buttons:

image Align to Page. Click to align the blend objects perpendicular to the horizontal axes.

image Align to Path. Click to align the blend objects perpendicular to the path.

image Click OK.

Creating Blends with the Blend Tool

image

IL 6.3

If you want to specify the locations where the blend takes place, you can use the Blend tool on the Tools panel. The Blend tool allows you to select the anchor points on the objects to determine the direction of the blend. For the best results and smoothest transitions, click anchor points on corresponding locations on the objects. If you’re not sure which anchor points to use, you can also select an object’s fill to let Illustrator select the anchor point for you. Experiment with it to determine what works best for you.

Create a Blend with the Blend Tool

image Select two or more objects or groups (with space in between them) that you want to blend.

image Select the Blend tool on the Tools panel.

image

image Click the fill of the first object (not the center point) to let Illustrator determine an anchor point to use, or click the anchor point that you want to use.

image Click the fill or an anchor point on the next object. If the path is open, click an endpoint.

image

For the best results and smoothest transitions, click anchor points on corresponding locations on the objects.

image Continue to click corresponding anchor points on the selected objects.

image To release the blend objects, select the blend, click the Object menu, point to Blend, and then click Release.

image

Modifying Blend Objects

image

IL 6.3

After you create a blend, you can use commands on the Blend submenu to reverse stacking order, reverse spine location, and replace the spine. These commands allow you to quickly change the look of the blend. If you want to modify a blend, you can change blend objects using other Illustrator features, such as recoloring, reshaping, or transforming. Experiment to determine what works best for you.

Modify Blend Objects

image Reverse Stacking Order. Changes the stacking order (front to back) without changing the x/y location. Select a blend object, click the Object menu, point to Blend, and then click Reverse Front to Back.

image

image Reverse Spine. Changes the x/y location of the blend objects without changing the stacking order. Select a blend object, click the Object menu, point to Blend, and then click Reverse Spine.

image

image Replace Spine. Replaces the current spine in a blend with a new path. Create a new path for the spine, select a blend object and the new path, click the Object menu, point to Blend, and then click Replace Spine.

image Recolor. Select all the objects in the blend that you want to recolor, click the Recolor Artwork button on the Control panel, specify the color changes you want, and then click OK.

image Transform. Select all the objects in the blend, and then use the object’s bounding box, the Free Transform tool, or other transformation tools.

image Reshape Path. Move one of the original blend objects with the Direct Selection tool or use any of the reshaping path tools.

image

Setting Transparency Options

image

IL 3.3, 5.1

Transparency, or the opacity of an object (to what degree you can see through the object), is set in Illustrator by adjusting the Opacity option in the Transparency, Control, or Appearance panels. The Opacity option allows you to specify a percentage to set the transparency level. Along with opacity, you an also change the blending mode, which controls how object colors blend with other object colors below it. You can apply transparency options to an object, group, or layer. This includes an object’s fill or stroke, and type.

Change the Opacity or Blending Mode of an Object

image Select an object, group, or layer.

image For a layer, click the target circle on the Layers panel.

image For type, select individual characters or the entire object.

image For an object’s fill or stroke, click the target circle on the Layers panel, and then click Fill or Stroke on the Appearance panel.

image

image Select the Transparency panel.

image

image To change opacity, click the Opacity list arrow, and then specify a percentage.

image To change the blending mode, click the Blending Mode list arrow, and then select a blending mode.

image

Controlling Transparency Effects

image

IL 3.3

When you apply a blending mode to a group, the blend is applied to all the objects in the group as well as all the objects below it. If you want to isolate the blend to only the objects nested in the group, you can use the Isolate Blending option in the Transparency panel. You can also use the option on individual objects with overlapping strokes and fills. If objects in a group overlap, you can use the Knockout Group option to control whether objects will show through each other (except for semi-transparent objects) or be knocked out.

Isolate a Blending Mode to Certain Objects

image Click the target circle for a group or layer on the Layers panel that contains nested objects with a blending mode.

image Select the Transparency panel.

image Click the Options menu, and then click Page Isolated Blending.

image
image

Use the Knockout Group Option

image Click the target circle for a group or layer on the Layers panel that contains nested objects.

image Select the Transparency panel.

image Click the Options menu, and then click Page Knockout Group to knock out the objects so that you can’t see through them. However, you’ll still see through any semi-transparent objects. Deselect this option to allow objects to be seen through each other.

image
image

Using the Transparency Grid

image

IL 3.3

The Transparency grid makes it easier to work with semi-transparent objects. The gray and white checkerboard background allows you to distinguish between different levels of transparencies. You can quickly show or hide the transparency grid by using the Show Transparency Grid command on the View menu. Before you use the command, you can customize the look of the grid in the Document Setup dialog box.

Select Transparency Grid Preferences

image Click the File menu, and then click Document Setup.

image Click the Grid Size list arrow, and then select a size: Small, Medium, or Large.

image Click the Grid Colors list arrow, and then select a color: Light, Medium, Dark, or a specific color.

image Select the Simulate Colored Paper check box to simulate the use of colored paper, which blends with objects.

image Click the Preset list arrow, and then select a resolution.

image Click OK.

image

Did You Know?

You can show and hide the transparency grid. Click the view menu, and then click Show Transparency Grid or Hide Transparency Grid.

Applying Gradients

image

IL 3.6

A gradient is a smooth transition between two or more colors in an object. You can apply one of Illustrator’s built-in gradients or create one of your own by using the Gradient panel (New!). The built-in gradients are available from gradient libraries. After you apply a gradient, you can change the direction or smoothness of the color transition.

Apply a Gradient Fill to an Object

image Select an object.

image For type, convert it to outlines (click the Type menu, and then click Create Outlines), or select the type, and then select Add New Fill from the Appearance panel menu.

image Select the Swatches panel.

image To open a gradient library, click the Swatch Libraries menu, point to Gradient, and then select a gradient library.

image

image Click a gradient swatch on the Swatches or gradient library panel.

image From the Gradient panel, you can use the Gradient Fill box list arrow (New!) to apply any of the gradients on the Swatches panel.

image
image
image

When you select a swatch from a gradient library, it’s automatically added to the Swatches panel.

Did You Know?

You can expand a gradient fill to create an effect. Select an object with a gradient fill, click the Object menu, click Expand, click the Specify option in the Expand Gradient To area, and then enter the number of objects that you want to create. For a smooth color transition, enter a large number (100), and then click OK.

Creating Gradients

image

IL 3.6

Instead of using one of Illustrator’s built-in gradients, you can create your own by using the Gradient panel. It’s easy and you can be creative in the process. You can create a gradient with two or more colors and add transparency (New!). There are two types of gradients: Radial (circular) and Linear (horizontal). After you create a gradient, you need to save it in the Swatches panel in order to use it again later.

Create a Gradient Fill for an Object

image Select an object.

image

image Select the Gradient panel.

image

image Click the Gradient Fill box on the Gradient panel.

image Click the left color stop and use the Color panel to create the color you want, or Alt+click (Win) or Option+click (Mac) a color swatch on the Swatches panel.

image Repeat the previous step for the right color stop.

image Click the Type list arrow, and then select a gradient type: Radial or Linear.

image To add color stops, click below the gradient spectrum in a blank area. To remove a color stop, drag it down and away from the gradient spectrum.

image To adjust the amount of each color in the gradient, drag the diamond above the gradient spectrum.

image To add transparency, select a color stop, and then specify an Opacity value.

image

image To save the gradient, drag the Gradient Fill box from the Gradient panel to the Swatches panel.

image To save and name the gradient, click the Gradient Fill box on the Gradient panel, click the New Swatch button on the Swatches panel, enter a name, and then click OK.

image

Editing Gradients

image

IL 3.6

After you apply a built-in gradient or use one of your own, you can edit it. You can edit a gradient in an object and keep the gradient in the Swatches panel unchanged or you can edit the gradient in the Swatches panel and keep the gradient in an object unchanged. Editing a gradient is similar to creating one. The techniques are the same. All you need to do is select the element that you want to edit.

Edit a Gradient

image Select an object with a gradient, or click the gradient swatch on the Swatches panel that you want to edit.

image

image Select the Gradient panel.

image Click the Gradient Fill box on the Gradient panel, or click the Gradient Fill box list arrow (New!), and then select one of the saved gradients (from Swatches panel).

image

image To change the gradient type, click the Type list arrow, and then select a gradient type: Radial or Linear.

image Do any of the following:

image Add color stops. Click below the gradient spectrum in a blank area.

image Remove color stops. Drag it down and away from the gradient spectrum.

image Move color stops. Drag it or enter a Location value (New!).

image Duplicate color stops. Alt+drag (Win) or Option+drag (Mac) a color stop.

image Adjust color amount. Drag the diamond above the gradient spectrum.

image Change Transparency. Select a color stop, and then specify an Opacity value (New!).

image

image To save the gradient, Alt-drag (Win) or Option-drag (Mac) the Gradient Fill box from the Gradient panel over the old gradient on the Swatches panel.

image

Using the Gradient Tool

image

IL 3.6

The Gradient tool on the Tools panel allows you to change how a gradient appears for an object. You can change how gradient colors blend, the angle of a linear gradient, and the location of the center for a radial gradient with a drag of the mouse over the gradient fill. You can also edit gradient colors on the object (New!) by adding or changing color stops, applying transparency to color stops, and changing gradient direction (linear) or angle (radial).

Use the Gradient Tool to Change a Gradient

image Select an object with a gradient that you want to change.

image Double-click the Gradient tool on the Tools panel, which will bring up the Gradient panel.

image

image Do any of the following:

image

image Short Color Transitions. Drag the diamond icon on the object a short distance.

image

image Change Color Stops. Click below the spectrum line to add, drag to move, and drag away to remove color stops.

image Change Transparency. Double-click a color stop on the object, and then specify an Opacity value in the popup Gradient panel.

Creating a Gradient Mesh

image

IL 6.2

A mesh object is a multicolored gradient type object that allows colors to flow in different directions and transitions from one point to another. A mesh object uses mesh lines (like a grid) to make it easier for you to modify color flow, transitions, and intensity. The points in the grid are called mesh points (diamonds). Mesh points are like anchor points, except you can assign color to them. The area between four mesh points is a mesh patch, which you can modify the color. You can create two types of mesh objects. One with an irregular pattern of mesh points or one with a regular pattern of mesh points.

Create a Gradient Mesh

image Select an object.

image Do one of the following:

image Irregular Pattern. Select the Mesh tool on the Tools panel, select a fill color for mesh points, click to place the first mesh point, and then continue to click to place other mesh points.

image

image Regular Pattern. Click the Object menu, and then click Create Gradient Mesh. Set the number of rows and columns, select the highlight direction, enter a percentage of white highlight (100% = white, 0% = no white), and then click OK.

image

image To edit a mesh object, select the Mesh tool on the Tools panel, and the drag to move a mesh point, Alt-click (Win) or Option-click (Mac) a mesh point to delete it, or select a color, and click to add a mesh point.

image
