Munehiro Yamamoto submitted an update to the
spotxcolor
package.
Version: 1.4 2026-03-17
License: lppl1.3c
Summary description: Modern spot color support for the xcolor package
Announcement text:
----------------------------------------------------------------------
Changes since v1.0:
- Fixed spot color output for \color, \textcolor, and \pagecolor.
In v1.0, these commands fell back to CMYK values instead of
producing true PDF Separation color space operators.
As of v1.4, all standard xcolor commands — including tinted
expressions like DIC161s!50 — correctly generate spot color
output on all engines (pdfTeX, LuaTeX, XeTeX, and dvipdfmx).
- Fixed spot color output for PGF/TikZ drawing commands.
TikZ \fill, \draw, and low-level PGF color commands now produce
spot color operators for both fill and stroke independently.
- Fixed spot color output for PGF uncolored pattern fills.
Hatching and dot patterns (both legacy `patterns` and modern
`patterns.meta` libraries) now use a [/Pattern [/Separation ...]]
color space, producing true spot color output in pattern fills.
- Added user manual (spotxcolor.tex) with a feature/limitation
summary table.
