Adobe CMM vs OS color management Windows 7 64bit

Adobe CMM vs OS color management Windows 7 64bit

2010-11-21 by bwinkjet

Hi,
I use the full line of datacolor color management on Windows 7, 64 bit with Photoshop CS5.  Canon has made available (11/15/2010) a print plug in for their iPF 6300/8300 printers.  They do not use Adobe CMM in the 64 bit mode, but rather one must use "OS color engine" or some such phrase.  Does this mean that the default is Microsoft WCS which is the way I interpret it?  If so, is there any loss by using the WCS default? (They ask you to contact Adobe for their 64 bit Adobe CMM which is NOT available as far as I can tell from the Adobe website)  Thanks to anyone who may shed light on this issue.

Which CMM is used does not really cause much variation in results; it's a bit like worrying about which brand of motor oil is used in your car...  As long as the workflow is functioning for you, I wouldn't worry about it.

Whilst normally I'd completely agree that such concerns are not really that relevant, in the Mac version of the Canon plugin there is a similar 64 bit limitation.

This means that in 64 bit I only get perceptual, sat or rel col with no BPC available.

The option of BPC can be quite handy :-)

Depending on the profiles I'm using and what software made them, I can see noticeable difference in -some- images between the options.

I'll admit that it's not much, but it would be nice if Adobe did get round to making the external CMM run OK at 64 bit (Mac and Win)

I don't disagree; though I'd rather that Adobe perform the much simpler task of adding a checkbox to turn BPC <off> in Lightroom first, before they develop an entire 64bit CMM to allow users to turn it <on> in direct export modules...
