Re: Printing Ink Separation6.tiff Colour Management Issue

2013-02-05 by David

Ross,
    I don't have any recent experience with PS Elements, and none with QTR and Elements.  But, in recent versions of PS on the Mac, it is impossible to turn off color management.  There are two ways that I know of to print without color management:

An Adobe utility: http://helpx.adobe.com/photoshop/kb/no-color-management-option-missing.html

Roy's QTR-Print-Tool program:http://www.quadtonerip.com/html/QTRprinttool.html

For the ink separation page, it is also important to choose the "Quadtone Rip Calibration" mode in the QTR panel of the print dialog.

I haven't used either of these much, but I just tried the Adobe utility, and it seems to do what it is supposed to, at least with OS 10.6.8

I hope this is helpful.

David

I can then print in QTR calibration mode.  I have no option for "no colour management" at the printing stage, however I think I've read that although Color Sync is selected, it doesn't necessarily mean it's doing anything, so may be equal to no colour management.

Having reset the ink limit, in this case to 30%, paper white has a density of 0.08, the 5% step is 0.28, 50% is 1.29, 70% is 1.51 going up to 100% in increments of 0.03 to 0.01.  I would have thought this wedge should be lighter and much more even.
