- Project scope
- Related: Deliverable, Creative brief, Sign-off
A written statement of what a design project will and will not include, such as deliverables, number of revisions, and supported media. It protects both designer and client from unplanned work.
- Creative brief
- Related: Project scope, Target audience, Sign-off
A short planning document that captures the client's goals, target audience, key message, budget, and deadlines. Designers use it to align decisions with business objectives before starting artwork.
- Deliverable
- Related: Project scope, Sign-off, Output profile
Any final file or artifact handed to a client or publisher, such as a print-ready PDF or a set of web images. Deliverables are usually listed explicitly in the project scope.
- Sign-off
- Related: Deliverable, Project scope, Proof
Formal client approval of a stage or final artwork, often recorded in writing or email. Once given, further changes typically require a new change order or additional fee.
- Target audience
- Related: Creative brief, Visual hierarchy
The specific group of people a design is meant to reach, defined by factors such as age, interests, or reading context. Audience characteristics guide choices in color, type size, and tone.
- Change order
- Related: Project scope, Sign-off
A documented amendment to an approved project that records added work, revised deadlines, or extra cost. It keeps scope changes visible and prevents unpaid labor.
- Visual hierarchy
- Related: Contrast, White space, Focal point
The arrangement of elements so viewers notice the most important content first, then move through secondary information. Size, contrast, position, and color are the main tools for building it.
- Focal point
- Related: Visual hierarchy, Contrast, Rule of thirds
The area of a composition that first attracts the eye, often created through contrast, isolation, or placement near a strong axis. A layout usually needs one clear focal point.
- Rule of thirds
- Related: Focal point, Balance
A composition guideline that divides a frame into a three-by-three grid and places key subjects near the intersecting lines. It tends to produce more dynamic images than dead-center placement.
- Balance
- Related: Visual hierarchy, White space
The distribution of visual weight across a composition. Symmetrical balance mirrors elements around an axis, while asymmetrical balance offsets a large shape with smaller or darker ones.
- Contrast
- Related: Visual hierarchy, Value, Focal point
The degree of difference between elements in value, color, size, or shape. Strong contrast improves legibility and creates emphasis; weak contrast can make a design feel flat or hard to read.
- White space
- Related: Margin, Visual hierarchy, Balance
Empty or unoccupied areas in a layout, including margins, gutters, and space around text. It is an active design element that improves readability and gives content room to breathe.
- Alignment
- Related: Grid, Margin
The placement of elements along shared edges or invisible axes so they relate to one another. Consistent alignment makes a layout look intentional and organized.
- Grid
- Related: Alignment, Margin, Gutter
An underlying structure of columns, rows, and margins that guides where elements are placed. Grids create consistency across pages or screens and speed up layout decisions.
- Margin
- Related: Gutter, Bleed, White space
The space between the edge of a page or artboard and the content area. Margins frame the design and protect content from being trimmed or clipped.
- Gutter
- Related: Margin, Grid
The space between columns of text or between facing pages in a spread. Adequate gutters keep columns distinct and prevent text from running together.
- Bezier curve
- Related: Anchor point, Path, Direction handle
A smooth curve defined by anchor points and direction handles that control its shape. Vector drawing tools use Bezier curves to create precise, scalable paths.
- Anchor point
- Related: Bezier curve, Path, Direction handle
A point on a vector path where the path changes direction or where a curve begins and ends. Anchor points can be moved, added, or deleted to reshape artwork.
- Path
- Related: Anchor point, Stroke, Fill
A vector line or shape made of anchor points connected by straight or curved segments. Closed paths enclose a fill area; open paths can be stroked but do not enclose space.
- Direction handle
- Related: Bezier curve, Anchor point
A control extending from an anchor point that determines the angle and length of the curve leaving that point. Dragging a handle reshapes the adjacent segment.
- Fill
- Related: Stroke, Path, Swatch
The interior color, gradient, or pattern applied inside a closed vector shape. Fill is independent of stroke and can be set to none to leave the shape hollow.
- Stroke
- Related: Fill, Path, Appearance panel
The outline painted along a vector path, defined by color, width, and dash pattern. Stroke settings determine how thick or visible the edge of a shape appears.
- Compound path
- Related: Pathfinder, Path
Two or more paths combined so they behave as a single object, allowing holes such as the center of the letter O. Overlapping areas can be excluded from the fill.
- Pathfinder
- Related: Compound path, Path
A set of operations that combine or subtract overlapping vector shapes, producing results such as unite, minus front, and intersect. It is a fast way to build complex silhouettes.
- Live trace
- Related: Raster image, Vector graphic, Anchor point
A feature that converts raster images into editable vector paths by detecting edges and color regions. Results usually need cleanup because tracing can create excessive anchor points.
- Vector graphic
- Related: Raster image, Bezier curve, Resolution
Artwork described by mathematical paths and points rather than a grid of pixels. It can be scaled to any size without loss of sharpness, making it ideal for logos and signage.
- Raster image
- Related: Vector graphic, Resolution, Pixel
A picture made of a fixed grid of pixels, such as a photograph or scanned artwork. Enlarging it beyond its native size reveals visible pixelation and softens edges.
- Pixel
- Related: Raster image, Resolution
The smallest addressable square of color in a raster image or on a screen. Image dimensions and file size are commonly expressed as a count of pixels.
- Resolution
- Related: Pixel, Raster image, DPI
The amount of detail an image or output device can represent, often stated in pixels per inch for images or dots per inch for printers. Higher resolution yields finer detail at a larger file size.
- Color mode
- Related: CMYK, RGB, Spot color
The numerical system used to describe color in a document, such as RGB for screens or CMYK for process printing. Choosing the correct mode early prevents unwanted color shifts later.
- CMYK
- Related: RGB, Color mode, Spot color
A subtractive color model using cyan, magenta, yellow, and black inks, standard for commercial offset and digital printing. Colors are created by ink absorbing light reflected off paper.
- RGB
- Related: CMYK, Color mode, Gamut
An additive color model using red, green, and blue light, used by monitors, phones, and cameras. RGB files usually must be converted for print because some bright colors cannot be reproduced in ink.
- Spot color
- Related: CMYK, Swatch, Color mode
A pre-mixed ink printed from its own plate rather than built from process inks, often specified by a numbered swatch system. Spot colors give consistent, sometimes unattainable, results and add plate cost.
- Gamut
- Related: RGB, CMYK, Color mode
The range of colors a device or color model can reproduce. Colors outside a printer's gamut are described as out of gamut and will shift when converted.
- Swatch
- Related: Spot color, Fill, Global color
A named, saved color or gradient stored in a document's palette so it can be applied consistently. Editing a swatch updates every object that uses it.
- Kerning
- Related: Tracking, Leading, Typeface
Adjustment of the space between a specific pair of characters to correct awkward gaps, such as between an A and a V. It is applied manually rather than across whole ranges of text.
- Tracking
- Related: Kerning, Leading
Uniform adjustment of spacing across a range of characters, loosening or tightening an entire word or paragraph. Unlike kerning, it affects all letter pairs equally.
- Leading
- Related: Baseline, Kerning, Typeface
The vertical distance between baselines of consecutive lines of text. Too little leading crowds lines; too much breaks the reader's flow down the page.
- Baseline
- Related: Leading, Typeface
The invisible line on which the bottom of most letters sits, excluding descenders. Leading is measured from one baseline to the next.
- Typeface
- Related: Font, Kerning, Leading
A complete design of letters, numbers, and symbols sharing consistent visual characteristics, such as Helvetica or Garamond. A font is the specific file or style of that design.
- Font
- Related: Typeface
The specific digital file or style instance of a typeface, such as bold or italic at a given size. People often use the word loosely to mean typeface.
- Hierarchy of type
- Related: Visual hierarchy, Typeface
The use of size, weight, color, and spacing to rank headings, subheads, and body copy so readers can scan in order of importance. It mirrors visual hierarchy at the text level.
- Layers panel
- Related: Artboard, Linked image, Appearance panel
A panel that lists stacked objects or groups, letting you select, hide, lock, and reorder them. Layers keep complex documents manageable and control which items appear in front.
- Artboard
- Related: Layers panel, Output profile
A defined drawing area within a document that represents one page, screen, or output size. Multiple artboards let one file hold several versions or formats.
- Linked image
- Related: Embedded image, Package, Layers panel
A placed image that remains stored in an external file and is referenced by the document rather than embedded. Links keep files small but require the original to be present or packaged.
- Embedded image
- Related: Linked image, Package
A placed image whose data is stored inside the document file. Embedding makes the file self-contained but increases its size and prevents automatic updates from the original.
- Package
- Related: Linked image, Preflight, Sign-off
A command that gathers a document and all its linked files and fonts into one folder for handoff or archiving. It helps prevent missing-asset errors at a print vendor.
- Preflight
- Related: Package, Resolution, Output profile
An automated check for output problems such as missing links, low-resolution images, or RGB colors in a print job. Running it before export catches costly errors early.
- Bleed
- Related: Trim size, Margin, Output profile
Extra artwork extending past the trim line so color reaches the paper edge after cutting. Without bleed, slight misalignment leaves thin white slivers on finished pieces.
- Trim size
- Related: Bleed, Crop marks
The final dimensions of a printed piece after it is cut down. Design files are built larger than trim size to include bleed and crop marks.
- Crop marks
- Related: Trim size, Bleed
Short printed lines outside the trim area that show the printer where to cut. They are added during output and must sit outside the bleed.
- Output profile
- Related: Deliverable, Preflight, Resolution
A saved set of export settings, such as format, resolution, color space, and compression, tailored to a destination like print or web. Reusing profiles keeps output consistent.
- DPI
- Related: Resolution, Pixel, Bleed
Dots per inch, a measure of how many printer dots fall in one inch of output. Higher values produce finer print detail; it differs from pixels per inch used for screen images.
- Proof
- Related: Sign-off, Preflight
A preview of the design as it will be produced, used for checking color, text, and layout before final output. Clients often approve a proof before printing begins.
- Overprint
- Related: CMYK, Spot color
A setting that prints one ink on top of another instead of knocking out the area beneath it. It is used to avoid registration gaps but can cause unexpected color where it is unintended.
