Adobe Certified Professional Illustrator key terms

Images built from mathematically defined paths, points, and curves rather than a grid of pixels. They can be scaled to any size without losing sharpness, which makes them ideal for logos, icons, and print artwork.

A picture made of a fixed grid of colored pixels. Enlarging it too far reveals individual pixels and softens edges, so it is best suited to photographs and continuous-tone artwork.

The amount of detail an image holds, usually expressed as pixels per inch or dots per inch. Higher values preserve more detail but increase file size and demand more processing power.

Pixels per inch; a measure of how many image pixels occupy one inch of a screen or layout. It describes image density, while DPI describes printer output dots.

Dots per inch; the number of ink dots a printer can place in one linear inch. It describes print output capability, not the pixel density stored inside a file.

The system used to describe colors in a document, such as RGB for screens or CMYK for process printing. Choosing the right mode early prevents unwanted color shifts later.

A color model that mixes red, green, and blue light to create colors. It matches how monitors display color and is the standard working mode for screen-based artwork.

A color model that combines cyan, magenta, yellow, and black inks. Commercial presses use it for process color printing, so artwork destined for print is usually built in this mode.

A pre-mixed ink printed from its own plate instead of being built from process inks. It delivers consistent, often vivid color and is common in branding and packaging work.

Extra artwork extending beyond the trim edge of a page so slight cutting misalignment leaves no white slivers. It is typically set a few millimeters beyond the final size.

The final dimensions of a printed piece after it has been cut down. Designers set up documents at this size and add bleed outside it.

A defined canvas area inside an Illustrator document that represents a page or design surface. A single file can hold many artboards for different sizes or variations.

A point on a path where direction changes or a curve begins and ends. Dragging its handles reshapes the adjacent segments and controls how curved or sharp the path appears.

A smooth curve defined by anchor points and control handles that pull the line toward them. Adjusting handle length and angle changes the curve's shape precisely.

A line or shape drawn in a vector program, made of anchor points joined by straight or curved segments. Paths can be open or closed and can carry fills and strokes.

The outline applied to a path, with adjustable width, color, and dash pattern. It follows the path's shape and can be aligned to its center, inside, or outside.

The color, gradient, or pattern applied inside a closed path. It can be a solid color, a gradient, or a pattern swatch.

A saved color, gradient, or pattern stored in a panel for reuse. Using swatches keeps colors consistent and lets you update every use at once.

A swatch whose edits automatically update every object using it. Designers rely on it to recolor a whole layout quickly and keep branding consistent.

A named, stackable level that holds artwork and can be shown, hidden, locked, or reordered. Layers help organize complex documents and separate elements for editing.

Two or more objects combined so they move and transform as a single unit. Groups can be nested and selectively entered to edit individual items inside.

Multiple paths combined into one object so holes appear where they overlap. It is commonly used to cut out letters or create ring and donut shapes.

A panel of operations that combine or divide overlapping shapes, such as unite, subtract, and intersect. It is a fast way to build complex silhouettes from simple shapes.

A tool that merges or removes regions of overlapping shapes by dragging across them. It lets you sculpt combined artwork without opening a separate panel.

A shape that hides everything outside its boundary while revealing the artwork beneath it. It is often used to crop a photo into a custom outline.

A mask that uses grayscale values to make parts of artwork transparent. Lighter areas show more, darker areas hide more, allowing soft fades.

A panel listing the fills, strokes, and effects applied to an object, editable in any order. It lets you stack multiple fills and strokes on one object.

Live, non-destructive changes such as drop shadows, blurs, or distortions applied to objects. They remain editable and can be removed without altering the underlying artwork.

Converting vector artwork or live effects into pixels. It is sometimes required for certain filters or output, but it removes scalability and editability.

A reusable piece of artwork stored in a panel and placed as instances. Editing the symbol updates every instance, which is efficient for repeated elements.

Text that flows along the curve of a path rather than a straight baseline. Moving the path reshapes the text, and its start point can be adjusted.

Converting live editable text into vector shapes. It preserves the exact look for output or sharing but removes the ability to edit characters or font settings.

A standardized PDF subset for print exchange that restricts features and embeds fonts and color data. Printers request it to ensure files render predictably on press.

An automated check that inspects a file for problems before output, such as missing fonts, low-resolution images, or missing bleed. It catches issues before they reach the printer.

Scalable Vector Graphics; an open, text-based vector format used widely on the web. It stays sharp at any size and can be styled or animated with code.

Saving artwork into a different file format or settings for a specific use, such as PNG for screens or PDF for print. Export settings control resolution, color, and compression.

A command that gathers a document, its linked images, and its fonts into one folder. It ensures a printer or collaborator receives every file needed to open the job correctly.

A panel that lists images placed in a document and shows whether each is current, missing, or modified. It lets you update, relink, or embed linked files.

A document stating a project's goals, audience, deliverables, budget, and deadlines. Designers use it to align expectations and guide decisions throughout the work.

A specific file or artifact a designer agrees to hand over, such as a logo package or print-ready PDF. Naming them clearly in advance prevents scope disputes.

A preview of the work sent to a client or printer for approval before final production. Reviewing proofs catches errors while changes are still inexpensive.

Legal rights protecting creations such as artwork, logos, and fonts from unauthorized use. Designers must confirm they have rights to assets and understand ownership terms.

The terms under which a designer or client may use fonts, images, or other assets. Licenses specify allowed uses, durations, and restrictions, and should be checked before delivery.
