Quick reference

Working in the Design Industry

  • A project brief defines scope, audience, deliverables, and constraints; written approval of the brief precedes production work.

  • Copyright protects original fixed expression automatically on creation; registration strengthens enforcement but is not required for protection.

  • Work made by an employee within job scope is a work made for hire, so the employer holds copyright unless a contract assigns otherwise.

  • A standard license grants defined usage rights; an exclusive/transfer license moves ownership and must be in writing.

  • Client-supplied fonts, stock images, and logos require documented rights; scope of use (media, territory, duration) is stated in the license.

  • A statement of work (SOW) lists deliverables, revisions count, timeline, and payment terms; change orders cover out-of-scope additions.

  • Proof approval transfers final content responsibility to the client; version control names files by client, project, and revision number.

  • RGB is standard for screen delivery; CMYK is standard for process-color print; spot colors are specified via Pantone or similar matching systems.

  • Design files should be archived with linked assets using package/collect functions so fonts and images remain traceable.

Understanding Digital Images

  • Raster images store pixels on a grid; vector graphics store mathematical paths and scale without quality loss.

  • Image resolution in PPI equals pixels divided by physical size in inches (PPI = px / in); print commonly targets 300 PPI at final size.

  • Total pixel count equals width in pixels times height in pixels; doubling both dimensions quadruples file size.

  • Bit depth sets tonal levels per channel: 8-bit = 256 levels, 16-bit = 65,536 levels; 8 bits per channel RGB yields 24-bit color.

  • File size for uncompressed raster data equals width x height x channels x bit depth / 8 bytes.

  • RGB uses additive light with a wide gamut; CMYK uses subtractive ink with a smaller gamut, so RGB-to-CMYK conversion can clip saturated colors.

  • Lossy compression (JPEG) discards data on each save; lossless formats (PNG, TIFF, PSD) preserve pixel data across edits.

  • Anti-aliasing softens edge pixels to reduce stair-stepping; upsampling cannot recover detail absent from the source pixels.

Creating Graphics and Illustrations

  • The Pen tool creates anchor points joined by Bezier segments; direction handles control curve shape, and Alt/Option drags break handle symmetry at a point.

  • Smooth points have collinear handles producing continuous curves; corner points have independent handles producing sharp direction changes.

  • The Pathfinder panel combines or divides overlapping shapes (Unite, Minus Front, Intersect, Exclude); the Shape Builder tool merges or deletes path regions interactively.

  • The Layers panel controls stacking order, visibility, and locking; sublayers group related objects within a parent layer.

  • Appearance attributes (fills, strokes, effects) can be applied to layers and groups, not only to individual objects.

  • Global colors update everywhere when edited, while spot colors map to named ink plates for output; process colors separate into CMYK.

  • Clipping masks hide artwork outside a topmost vector path; opacity masks use luminance or alpha to vary transparency.

  • Symbols place reusable linked instances that update from a master definition, reducing file size and edit effort.

  • Artboards define output regions within one document; each artboard can be exported separately with its own dimensions.

Publishing, Exporting, and Archiving

  • Save As AI keeps editable native layers and paths; PDF preserves editability when Illustrator editing capability is retained.

  • PDF/X-1a and PDF/X-4 are print-ready standards; X-4 permits transparency and RGB while X-1a flattens to CMYK with no transparency.

  • Flattening converts transparency into opaque art; rasterization settings (resolution, anti-aliasing) determine quality of flattened areas.

  • Export formats map to use: PNG for lossless web with alpha, JPEG for photographic web, SVG for scalable web graphics, EPS for legacy vector interchange.

  • The Save for Web/Export As dialog controls format, quality, dimensions, and color profile; preview size should match final display size.

  • Packaging (File > Package) collects the AI file, linked images, and fonts into one folder for handoff or archival.

  • Overprint Preview simulates how overlapping inks combine on press; Separations Preview checks individual color plates.

  • Archiving best practice stores the native editable file plus a PDF/X proof and a text manifest of fonts and links used.

  • Color conversion on export should be intentional: assign or convert to the destination profile rather than leaving mixed profiles.
