Professional type design is a sophisticated blend of visual art and systematic engineering. It extends beyond drawing characters into building a fully integrated, technically compliant software system. Professionals follow a rigorous seven-stage workflow to ensure optical quality and functional performance.

1. Conceptualization & Research

■ Context & Function: Defining the font’s purpose (text, display, or UI) and its stylistic identity.
■ Structural Parameters: Setting the vertical metrics such as Baseline, X-Height, and Descenders.
■ Prototyping: Sketching the core set of characters that serve as the "genetic code" for the entire typeface.

2. Digitization & Vector Engineering

■ Advanced Vector Drawing: Utilizing professional software (like Glyphs or FontLab) to construct characters using Bézier curves with optimized node placement.
■ Mastering: Drawing extreme weights (Thin and Black) to enable smooth Interpolation in Variable Fonts.

3. Metrics & Optical Mastering

■ Spacing & Metrics: Defining sidebearings to ensure balanced negative space and smooth text flow.
■ Optical Corrections: Applying "Overshoots" to rounded characters to ensure they appear visually aligned with flat ones.

4. Advanced Scripting & OpenType Features

This is the technical core, especially for Arabic scripts:
■ Contextual Substitutions (GSUB): Scripting the four contextual forms of Arabic letters (Initial, Medial, Final, Isolated).
■ Positioning (GPOS): Precise programming for diacritics and mark placement (Mark-to-Base/Mark-to-Mark).

5. Testing & Quality Assurance (QA)

Testing the font in real-world scenarios, auditing web formats (WOFF2), and ensuring the vector paths are free from geometric defects that might affect rendering.

6. Generation & Legal Documentation

Exporting the font in various formats (OTF, TTF, WOFF2) and embedding metadata, including intellectual property rights and End User License Agreements (EULA).

7. Visual Presentation & Distribution

Preparing Type Specimens that highlight the font's aesthetic beauty and functional strength for designers and developers.
