What is a swatch in Illustrator, and what is a color group?

A swatch is a saved, reusable color, tint, gradient, or pattern stored in the Swatches panel. A color group is a folder of related solid-color swatches (e.g., a brand palette) that can be created from selected artwork or via the Color Guide, and edited together with Recolor Artwork.

What is a global swatch and why is it useful?

A global swatch (marked with a small triangle/corner in the Swatches panel) keeps a live link to artwork: editing the swatch automatically updates every object that uses it — ideal for changing a brand color across an entire document at once.

What is the difference between process colors and spot colors?

Process colors are printed by mixing the four CMYK inks. Spot colors are premixed specific inks (e.g., Pantone) printed on their own plate, used for exact brand-color matching or colors outside the CMYK gamut.

What are the three gradient types available in Illustrator?

Linear (colors blend along a straight line), radial (colors blend outward from a center point in circles), and freeform (color stops placed anywhere on the shape as points or lines, blending organically).

What is a gradient mesh and how does it differ from a standard gradient?

A gradient mesh (Object > Create Gradient Mesh or the Mesh tool, U) overlays an object with a grid of mesh points, each of which can hold its own color that blends smoothly to neighboring points — enabling complex, multi-directional, photo-realistic shading impossible with simple linear/radial gradients.

In the Gradient panel, what do the color stops and the midpoint sliders control?

Color stops (under the gradient slider) set the colors and their positions along the gradient; the diamond midpoint sliders (above the slider) set where two adjacent colors are mixed 50/50, controlling how abruptly or gradually they blend.

What is Live Paint in Illustrator and what problem does it solve?

Live Paint (Object > Live Paint > Make, then Live Paint Bucket, K) converts paths into a group whose enclosed faces and edges can be filled/stroked directly by clicking, like a coloring book — it treats visually enclosed areas as fillable even when they aren't single closed paths.

In a Live Paint group, what are faces and edges, and what does gap detection do?

Faces are the enclosed areas you can fill; edges are the path portions between intersections that you can stroke. Gap Options (gap detection) lets Live Paint treat areas with small openings in the paths as closed, so paint doesn't leak through small gaps.

What is the difference between Point Type and Area Type in Illustrator?

Point Type is created by clicking with the Type tool: the line grows as you type and doesn't wrap (scaling the object scales the text). Area Type is created by dragging a text box (or clicking a closed path): text wraps automatically within the container's boundaries — best for paragraphs.

How do you convert Point Type to Area Type (and vice versa) in Illustrator?

Select the type object and choose Type > Convert to Area Type / Convert to Point Type, or double-click the small round widget on the right side of the type object's bounding box.

How do you create Type on a Path, and what happens to the original path?

Select the Type on a Path tool (or click a path's edge with the Type tool) and click the path — text then flows along the path, and the path itself loses its own fill and stroke attributes.

How do you flip text to the other side of a path, or slide it along the path?

With the Selection tool, drag the center bracket across the path to flip the text to the other side; drag the start, center, or end brackets along the path to reposition the text. Type > Type on a Path > Type on a Path Options offers effects, alignment, and a Flip checkbox.

What does 'Create Outlines' (Type > Create Outlines) do to text?

It converts live editable type into vector shapes (compound paths) matching each glyph. The text is no longer editable as type and no font file is needed to display it, but you can now edit the letterforms' anchor points like any other vector artwork.

Why would you outline type before sending a file to a printer, and what is the main drawback?

Outlining removes font dependency, guaranteeing the type renders identically even if the recipient lacks the font. Drawback: the text can no longer be edited or spell-checked as type (so keep a live-type copy), and small text may lose font hinting.

In Illustrator, what is the difference between Object > Expand and Object > Expand Appearance?

Expand converts an object's fill, stroke, or other basic properties into separate editable vector objects. Expand Appearance first converts live effects and appearance attributes (e.g., a Warp or Offset effect, brush strokes) into actual paths; after that, Expand can break them down further.

What does the Blend tool (Object > Blend > Make) do?

It creates a series of intermediate objects and colors between two or more selected objects, morphing shape, color, and size step by step along a blend path (the spine), which can be edited or replaced.

What are the three spacing options in Illustrator's Blend Options dialog?

Smooth Color (Illustrator auto-calculates enough steps for a smooth color transition), Specified Steps (you set the exact number of intermediate objects), and Specified Distance (you set the distance between the steps).

What is a symbol in Illustrator and what is its key advantage?

A symbol is reusable artwork stored in the Symbols panel; each placed copy is an instance linked to the master. Editing the master symbol updates all instances at once, and symbols keep file size small when artwork repeats many times.

What does 'breaking the link' to a symbol instance do, and which tool sprays multiple instances?

Break Link to Symbol converts the instance into ordinary editable artwork no longer updated by the master symbol. The Symbol Sprayer tool (Shift+S) sprays sets of many instances, which other symbolism tools can then shift, scale, spin, stain, or screen.

How do you create a seamless repeating pattern swatch in Illustrator?

Select the artwork and choose Object > Pattern > Make (or drag artwork into the Swatches panel). Pattern Edit mode lets you set the tile size and tile type (Grid, Brick by Row/Column, Hex) with a live repeat preview; saving adds the pattern as a fill swatch.

What is a clipping mask and which object acts as the mask?

A clipping mask (Object > Clipping Mask > Make, Cmd/Ctrl+7) uses the topmost selected object as a window: only the parts of the underlying artwork inside that top shape remain visible; everything outside is hidden (not deleted). The masking shape loses its own fill and stroke.

What is a compound path, and what happens where its subpaths overlap?

A compound path (Object > Compound Path > Make, Cmd/Ctrl+8) combines two or more paths into a single object; where the paths overlap, a transparent hole is punched (like the counter of the letter 'O'). All subpaths share the same fill and stroke attributes.

How do a clipping mask and a compound path differ in purpose?

A clipping mask hides artwork outside a shape without altering the underlying objects (non-destructive cropping/visibility). A compound path merges paths into one object and creates holes in overlapping areas, defining the object's actual fill geometry.

What does Image Trace do in Illustrator?

Image Trace (Window > Image Trace or the Control panel button) automatically converts a placed raster image (photo, sketch, scan) into vector paths using adjustable presets and settings; the result is a live trace object until you click Expand to get editable paths.

Name key Image Trace settings/presets that control the traced result.

Presets/modes such as High/Low Fidelity Photo, 3/6/16 Colors, Grayscale, Black and White, Line Art, and Sketched Art; key settings include Threshold (for black-and-white), Colors, Paths, Corners, Noise, and the Ignore White option.

After running Image Trace, why must you click 'Expand', and what does it produce?

The trace is a live, re-adjustable tracing object, not yet real geometry. Expand converts it into actual editable vector paths and anchor points that can be selected, recolored, and reshaped like any other Illustrator artwork.

What is the native Illustrator file format, and which format is the standard editable exchange format for vector artwork across applications?

AI (.ai) is Illustrator's native format, preserving all editability (layers, artboards, effects). EPS (Encapsulated PostScript) is the legacy cross-application vector exchange format, while PDF is the modern standard for sharing/printing vector artwork with wide compatibility.

What is SVG and why is it the preferred vector format for the web?

SVG (Scalable Vector Graphics) is an XML-based open vector format rendered natively by web browsers. It stays sharp at any size and screen density, has small file sizes for simple graphics, and can be styled/animated with CSS and JavaScript.

Compare AI, EPS, SVG, and PDF for preserving Illustrator editability and for sharing.

AI: full editability, best as the working master file, needs Illustrator. PDF: preserves vectors, universally viewable/printable (can embed AI editing data). SVG: web delivery, browser-native, keeps vector data but may simplify Illustrator-specific features. EPS: legacy print/exchange format lacking modern features like transparency support.

Which common image formats are raster rather than vector, and what key property (measured in ppi) governs raster quality?

JPEG, PNG, GIF, TIFF, and BMP are raster formats. Their quality is governed by resolution — pixel density measured in pixels per inch (ppi) — with roughly 300 ppi standard for print and 72 ppi traditional for screen graphics.
