Editing PostScript (section)

=== PostScript 3 ===
PostScript 3 (Adobe dropped the "level" terminology in favor of simple versioning) came at the end of 1997, and along with many new dictionary-based versions of older operators, introduced better color handling and new filters (which allow in-program compression/decompression, program chunking, and advanced error handling).

PostScript 3 was significant in terms of replacing the existing proprietary color electronic prepress systems, then widely used for magazine production, through the introduction of smooth shading operations with up to 4096 shades of grey (rather than the 256 available in PostScript Level 2), as well as DeviceN, a [[color space]] that allowed the addition of additional ink colors (called [[spot color]]s) into composite color pages.<ref name=":0" /><ref>{{Cite web |date=2002-06-04 |title=PostScript 3 General Information |url=https://pdfguru.com/ |archive-url=https://archive.today/20250304132704/https://web.archive.org/web/20030624050921/http://www.adobe.com/support/techdocs/210f6.htm |archive-date=2025-03-04 |access-date=2025-03-04 |website=Adobe}}</ref>
