About formats

AI (Adobe Illustrator Artwork) is the native file format of Adobe Illustrator, the industry-standard vector graphics editor first released in January 1987 for the Apple Macintosh. Early versions of the format were based on the PostScript page description language, with each file being a conforming EPS document that could be placed in other layouts and interpreted by PostScript printers. Starting with Illustrator 9 in 2000, Adobe transitioned the AI format to a PDF-based structure, embedding Illustrator-specific editing data within a valid PDF wrapper — this dual nature means modern AI files can be opened in any PDF viewer for display, while preserving the full editable artwork including layers, artboards, and live effects when reopened in Illustrator. The format supports complex vector constructs like gradient meshes, clipping masks, symbol libraries, transparency blending modes, and multiple artboards within a single document. One significant advantage is lossless scalability — artwork maintains perfect precision at any size, from favicon to billboard, because geometry is defined mathematically rather than as pixels. Deep integration with the Adobe Creative Cloud ecosystem is another strength, enabling seamless round-tripping between Illustrator, Photoshop, InDesign, and After Effects without format conversion. AI remains the de facto standard for professional illustration, logo design, and print production workflows worldwide.

SK1 is the native file format of the sK1 project), an open-source vector graphics editor and conversion engine started by Igor Novikov in 2003 as a successor to Bernhard Herzog's Skencil. The format evolved from the original SK format, extending its capabilities while maintaining the text-based, Python-readable syntax for describing vector documents. SK1 files encode complete document structures including multiple pages, layers, guidelines, and a full hierarchy of graphic objects — Bezier paths, rectangles, circles, polygons, text blocks, and embedded raster images — with attributes for fills (solid, gradient, pattern, hatching), strokes, and transformations. The sK1 project distinguished itself by focusing on prepress and professional print production features, adding CMYK color management, ICC color profiles, spot color support, and PDF/PostScript output — capabilities unusual in open-source vector editors. One advantage is professional color handling — sK1's CMYK workflows and color management make it one of the few open-source tools suitable for print-ready vector production. The project's companion tool, UniConvertor, leverages the SK1 format as an intermediate representation for converting between numerous vector formats (CDR, CMX, WMF, EMF, SVG, and others), giving SK1 significance beyond the editor itself as a universal interchange format. The text-based file structure preserves the readability and scriptability advantages inherited from Skencil's original SK format.
