QuadToneRIP version 2.7.4 Release Notes This is a Mac OSX release - primarily to fix some color management issues. Consistency of prints from various versions of Photoshop and Print-Tool over all the OSX versions, Photoshop versions and Print-Tool has been difficult. Lighter and darker prints have unfortunately happened quite a bit in the past. This version has been tested on OSX 10.6 Snow Leopard thru 10.9 Mavericks with Print-Tool for identical prints. Mac users are recommended to upgrade to this and print primarily through Print-Tool. It's recommended to use No Color Management and Application Management as the standard workflow. Photoshop can still be used -- it does print but variations may show up in different versions with different OS versions. The Mac release supports Mac OS X 10.5 Leopard through 10.9 Mavericks. Simply install this new version over existing versions. Please report any trouble especially with OS X Mavericks. -- One issue that has been noticed in Mavericks is that there appears to be bugs in the Printer Presets. Deleting Presets is one thing that triggers this problem but there appear to be others. So make sure you check that the Curves and Blend Sliders are correct when printing.
