GretagMacbeth is rolling out ProfileMaker 5.0.5 to its server now, with both the English and Japanese versions for Windows already available for download. The new version of the company's flagship profile creation and editing software tweaks the colour profiling engine for promised smoother colour transitions and better overall profile quality owing to revamped perceptual and colorimetric gamut mappings. The update is free to registered users of a previous 5.0.x release.
As of this writing the Mac version of the ProfileMaker 5.0.5 download is not yet available.
Update, December 5, 2005: GretagMacbeth has now posted ProfileMaker 5.0.5 for Mac.
