10. What is Clipping Mask?

A Clipping Mask uses one object (top layer) to hide portions of the objects below it.

11. What is the difference between Group and Compound Path?

  • Group: Links objects together but keeps shapes separate.

  • Compound Path: Merges objects into one path, allowing holes inside shapes.

12. What is Expand and Expand Appearance?

  • Expand: Converts strokes and effects into individual vector shapes.

  • Expand Appearance: Expands appearance or effect layers applied to an object.

13. What is Isolation Mode?

Isolation mode allows you to edit a single object or group without disturbing other artwork.

14. What is the Appearance Panel used for?

It helps manage fills, strokes, transparency, and multiple effects on a single object.

Image Trace converts raster images into editable vector shapes.

16. What new AI features were added to Illustrator in 2026?

Illustrator 2026 includes advanced Generative Vector, AI-powered Font Pairing, Automatic Color Harmonization, and Smart Layouts that adjust compositions automatically.

17. How do you optimize Illustrator files for faster performance?

  • Reduce anchor points

  • Use linked images instead of embedded

  • Clean up hidden objects

  • Use fewer effects

  • Save as PDF-compatible OFF

  • Rasterize heavy effects temporarily

  • Merge layers when possible

18. What is the difference between Save for Web and Export for Screens?

  • Save for Web: Older method, used primarily for compressing image-based exports.

  • Export for Screens: Modern tool for exporting multiple sizes, artboards, and formats simultaneously—ideal for UI and digital assets.

19. What is Variable Data in Illustrator?

Variable Data allows automatic updates of text, images, or colors using CSV files—useful for batch-generated business cards, labels, or product catalogs.

21. How do you optimize artwork for printing?

  • Use CMYK mode

  • Set bleed (usually 3–5 mm)

  • Convert text to outlines (if needed)

  • Embed fonts

  • Use high-resolution linked images

  • Use Overprint Preview to check trapping

22. What is the difference between Expand and Outline Stroke?

  • Expand: Converts everything including fills and effects into shapes.

  • Outline Stroke: Converts only the stroke to a closed vector path.

23. How do you use Global Colors?

Global colors allow you to apply one color to multiple objects. When you edit the color in the swatch, Illustrator updates all objects using that color automatically.

24. How do you create a gradient mesh?

Use the Mesh Tool (U) to insert mesh points and adjust color transitions within a single object—useful for realistic shading.

25. How do you prepare a logo in pure vector format?

  • Use shapes and Pen tool

  • Avoid raster images/effects

  • Convert strokes to outlines

  • Expand appearance

  • Save as AI, PDF, SVG, EPS

  • Keep clean geometry and minimal points
