Yes, but I mentioned it as a point to them using computers by at least that time. By the way, Illustrator came out in '87.
Adobe Illustrator was first developed for the Apple Macintosh in December 1986 (shipping in January 1987) as a commercialization of Adobe's in-house font development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop. Photoshop is primarily geared toward digital photo manipulation and photorealistic styles of computer illustration, while Illustrator provides results in the typesetting and logo graphic areas of design. Early magazine advertisements (featured in graphic design trade magazines such as Communication Arts) referred to the product as "the Adobe Illustrator". Illustrator 88, the product name for version 1.7, was released in 1988 and introduced many new tools and features.
Here's a bit about desktop publishing on Macs:
In 1985, the combination of the Mac, Apple's LaserWriter printer, and Mac-specific software like Boston Software's MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics—an activity to become known as desktop publishing. Initially, desktop publishing was unique to the Macintosh, but eventually became available for other platforms. Later, applications such as Macromedia FreeHand, QuarkXPress, and Adobe's Photoshop and Illustrator strengthened the Mac's position as a graphics computer and helped to expand the emerging desktop publishing market.
MacPublisher was sold in 1986 to Esselte Letraset, whose business in press-down dry transfer lettering was evaporating with competition from laser printers, notably Apple's pioneering LaserWriter printer. It was briefly sold as LetraPage, but dropped from the market when Letraset subsequently acquired Ready,Set,Go! from Manhattan Graphics.
I'm not at all saying you're incorrect about the early stuff, but if they were doing it by hand, it might not have been strictly by necessity.
