The turning point came with , which introduced global color management, layers (a feature FreeHand had first), and a major UI overhaul. However, the most legendary feature—the Pen Tool as we know it—was perfected during this era. Adobe refined the keyboard modifiers (holding Option/Alt to break handles, Command/Ctrl to move anchor points) into an ergonomic standard that every vector app now copies.

However, there was no intuitive way for artists to create those vector images directly on a screen. Warnock wanted to free designers from the constraints of hand-drawn paste-up boards. He envisioned a program where an artist could draw a curve on a computer and have it printed perfectly.
For years, Illustrator was Mac-only. Version 4.0 (1994) was the first native Windows version, but it was a flawed port—slow, buggy, and inferior to the Mac version. Many designers stayed with FreeHand.
The story of Illustrator begins not with a drawing tool, but with a printing language. Adobe Systems, founded by John Warnock and Charles Geschke, developed PostScript in 1985. PostScript allowed a computer to describe a page’s text and images mathematically (using lines and curves) rather than as a grid of pixels. This “vector” approach meant that any printer with a PostScript interpreter could produce high-quality, scalable output.
