REFINE STROKES
MYGRAPHICSLAB: ADOBE ILLUSTRATOR CS6

IN THIS LESSON, YOU WILL LEARN THAT:
Defining the features of generated strokes is an importantskill for creating illustrations
Strokes can have: Different kinds of endings (round, square, etc.) Effects (dashes, dots, etc.) Arrowheads at one end or the other or both
Brush strokes have complex sets of attributes assigned tothem – creating the appearance of anything from apaintbrush to a calligraphic penstroke

THE STROKE PANEL
The Stroke panel defines the minute features of a stroke,including line thickness, plus: How ends look (square, rounded, etc.) How corners look (mitered, round, beveled) How strokes are aligned (centered, inside, or outside)
The Stroke panel can be used to apply arrowheads as well asdashed or patterned lines

TWO VERSIONS OF THE STROKE PANEL
The Stroke panel To open the “permanent” Stroke panel,
choose Window > Stroke To expand the panel and display all
options, click the double arrowheadson the panel tab
To access a full but temporary Strokepanel: Click the underlined Stroke link on the
Control panel (objects with mixedstroke attributes can be selected)
OR When object is selected or when
multiple objects that have the samestroke attributes are selected, click theunderlined Stroke link on theAppearance panel

SETTING STROKE WIDTH
Three ways to change the weight (width) of a selected stroke or strokes Define stroke width by clicking the Up or Down arrow, by entering a value, or by
choosing a value from the Weight pop-up menu (this works in the permanent Strokepanel and the temporary Stroke panel that opens from the Control panel)
In the Appearance panel, select a Stroke square to display the Stroke Weight controls Choose a Stroke width directly from the Control panel

DEFINING STROKE ALIGNMENT
Stroke thickness (weight)can be added to theoutside of the stroke, theinside of the stroke, orcentered on the stroke
To define the alignment ofstroke on a path, chooseone of these options fromthe Stroke panel: Align Stroke to Center Align Stroke to Inside Align Stroke to Outside
Caution: When you connect strokes, they must have thesame alignment or they will not merge properly.

DEFINING STROKE CAPS
Endpoints of strokes can be: Butt — ending at the anchor
that ends the stroke Round Projecting — extending
beyond the edge of thestroke
Stroke caps are relevant onlyto open paths (where theends of the path are visible)
Choose one of the three capsfrom the Cap row in theStroke panel

CONTROLLING JOINS
Three ways to join angle paths Miter Join (pointed bends) Round Join (semicircular bends) Bevel Join (beveled bends)
Which kind of join might be good for a picture frame? Which type of join might be good for a sharply pointed star? Image shows from left: miter, round, and bevel joins

DEFINING ARROWHEADS
To apply an arrowhead (ortwo!) to a selected path,choose an arrowhead stylefrom either of the Arrowheadspop-up menus in the Strokepanel
Use the Align buttons to togglebetween having thearrowheads end at the end ofthe path, or extend beyond theedge of the path
Remove an arrowhead byselecting None from therelevant Arrowheads pop-upmenu

DEFINING DASHED AND DOTTED STROKES
Dashed and dotted lines are the breadand butter of many kinds of illustrations,including maps and flowcharts
To define a dashed and/or dotted line fora selected path: Select the Dashed Line checkbox in the
Stroke panel Enter a value in the first Dash field for the
length and a value in the first Gap field todefine the width of the first gap
To create a dot instead of a dash, definethe length of the “dash” to match theweight of the stroke
Defined dashes and gaps repeat, so to create more complex dashed/dotted lines,enter values in additional dash and gap fills
To control how dots or dashes fit around the corners, click the Preserves Exact Dashand Gap Lengths button to specify no adjustment at the corners, or click the AlignsDashes to Corners and Path Ends button to have the dashes adjust to fit symmetricallyat the corners

BRUSHES
Illustrator provides a wide varietyof preset brushes, ranging fromcharcoal strokes to calligraphicstrokes to arrows to patterns
There are five types of brushes: Art Bristle Calligraphic Scatter Pattern
Copyright © 2013 MyGraphicsLab / Pearson Education
BRUSHES ARE VECTOR
Brushes have the advantages of being easily editable, scalable vectors You can apply them to existing paths – created with the Pen or Pencil tool,
shapes, and so on You can draw with a brush using the Paintbrush tool

APPLYING A BRUSH STROKE TO A PATH
To apply a brush to an existing path: Select a path, and click a brush on the Brushes panel or on the
Brush Definition menu on the Control panelOR
Drag a brush from the Brushes panel onto a path

USING BRUSHES FROM LIBRARIES
Illustrator offers an impressive set of preset brushes Open brush libraries by clicking the Brush Libraries Menu button at
the bottom of the Brushes panel Apply a brush from the library directly to any path, or add brushes
from the library to the Brushes panel for later use

CREATING A CALLIGRAPHIC BRUSH
Calligraphic brush strokes vary in thickness as you draw,simulating calligraphy
To create a calligraphic brush: Click the New Brush button in the Brushes panel In the New Brush dialog box, click Calligraphic Brush, and
then click OK Enter a name in the Calligraphic Brush Options dialog box Define brush parameters – angle, roundness, and diameter Click OK, then apply the new brush to a path
Copyright © 2013 MyGraphicsLab / Pearson Education
CALLIGRAPHIC BRUSH SETTINGS
Angle: An angle of 0º produces astroke that is thin when drawnhorizontally and thick when drawnvertically; an angle of 90º producesthe opposite result
Roundness: Lower is less round Diameter: Size Drop-down menus:
Fixed keeps the value constant Random randomizes the value Other options are available
depending on whether you have adrawing tablet, and what kind
Preview your stroke in the dialogbox, adjust settings, and click OK

CREATING ART BRUSHES
Art brushes are based onselected artwork, which isthen converted into a brush
As the brush is applied, theartwork stretches to fill theapplied stroke
To create an art brush: Select the artwork that will
become the brush stroke Choose New Brush from the
Brushes panel menu Select Art Brush in the New
Brush dialog box Adjust the brush options in
the Art Brush Options dialogbox, name it, and click OK toadd the brush to theBrushes panel

CREATING SCATTER BRUSHES
Scatter brushes are similar to artbrushes in that they are based onselected artwork
Instead of stretching that artwork tofit a path, they scatter the artworkalong the path to which they areapplied
To create or edit a Scatter brush: Select the artwork on which you are
basing the brush, and choose NewBrush from the Brushes panel menu
In the New Brush dialog box, selectScatter Brush, and click OK
In the Scatter Brush Options dialogbox, enter a name, then define brushoptions, and click OK
Use the scatter brush to populate ascene with multiple images across apath

BRISTLE BRUSHES
Bristle brushes act liketraditional art brushes,bristles included
There are ten presets in theBristle Brushes library
Copyright © 2013 MyGraphicsLab / Pearson Education
PATTERN BRUSHES
Pattern brushes are useful fordrawing borders and can includeup to five tiles: Side Outer Corner Inner Corner Start End
Pattern Brushes are complex tocreate Easy method: Drag one of the
preset pattern brushes into theBrushes panel, and then double-click it to edit it
You can replace any of the presettiles with objects in your document’sSwatches panel

WHAT YOU CAN DO NOW
Define endings for strokes Define how angled strokes join Apply stroke effects like dots and dashes Create arrowheads Paint with brushes Choose brushes from libraries Create custom brushes

REVIEW: KEY POINTS
Strokes can be finely tuned Change alignment Change endings Change how angles display
Strokes can have: Arrowheads at either end or at both ends Dash and/or dot patterns
Brushes simulate paintbrushes Can be used to paint freehand Can be applied to existing paths
