Summary description: Modern spot color support for the xcolor package
Announcement text:
The spotxcolor package has been updated to version 1.0. This release brings major enhancements for complex graphics, ensuring that your spot colors remain print-safe across all major TeX engines. ## Major Changes in v1.0 (since v0.14): * Advanced TikZ/PGF Support: Integrated comprehensive patches to resolve ColorSpace dictionary collisions with PGF. Spot colors now work seamlessly with complex TikZ graphics, basic shapes, and function graphs without destroying PDF resources. * CMYK Pattern Fills: Injected a core patch into PGF to force uncolored patterns (both legacy patterns and modern patterns.meta) to use CMYK instead of hardcoded RGB. This guarantees that spot colors used in TikZ patterns safely fall back to CMYK, preventing print separation issues. * Explicit Driver Support: Improved compatibility and explicit fallback mechanisms for dvipdfmx, pdftex, and luatex. * License: Updated the package license to LPPL v1.3c or later.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/spotxcolor The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/spotxcolor/

spotxcolor – Modern spot color support for the xcolor package
This package provides robust spot color (e.g., DIC, PANTONE) support for the xcolor package across all major TeX engines. It resolves structural PDF issues found in the legacy spotcolor package and provides an explicit fallback mechanism for dvipdfmx (which is not fully supported by the colorspace package).
Supported major drivers: pdftex,
luatex, dvipdfmx (including
ptex/uptex), xetex.
