Turning off ColorSync

Hello, I just purchased a ColorMunki Design to profile my printer, an Epson L1800. When it's time to print the color chart, I was asked to turn off all color management. However, I failed to do this as the option was always greyed off and ColorSync would be selected by default. Please refer to the attached picture. As a result, the profile produced was way off. I need help in turning off ColorSync. [ MacBook Pro early 2011 / Mac OS X 10.11.2 / Colormunki Design 1.2.0 ].

Thank you in advance

Hello hasnul8286,


Actually, that's what you want. It finally occurred to me late last night what you were seeing in your initial post. I fired up i1Profiler to confirm. What the ColorMunki software is doing is automatically bypassing all ColorSync controls. That's why you can't do anything with the color settings. i1Profiler does the same thing:

Your last image above also plainly states just want you wanted to know; that color management has been disabled.


Sorry for the half-baked answer earlier. I do quite a bit of profiling and calibration, but it's usually months apart for the printers. By the time you do it again, you kind of have to remind yourself how.


The image from OS X's built in PDF generator is useless. I kicked one of my targets out that way, and then using i1Profiler's option to save the targets as a file. Comparing the two outputs easily shows that the PDF generated target isn't even close to the values that should be there. But that's all moot since the ColorMunki software is doing exactly what you want it to do - send a raw, untagged image to the printer.


Now for the bad news. We had one of these and finally sold it a couple of years ago. From a hardware standpoint, the ColorMunki is a very accurate spectrophotometer for the price. Much less than the cost of an i1 Pro 2. Independent labs have measured its ability as very high quality. The downfall of the ColorMunki package is the software.


For monitor profiles, I can only describe the results as strange, or out of whack. They look okay if you have nothing else to compare the results to, but it doesn't make very good monitor profiles. It fails miserably at printer profiles. When we had all three available at the time, we compared the profiles built for the same printer with a ColorMunki, i1 Pro 2 spectrophotometer, and an i1iSis. The profiles created by the latter two were identical, and as close as you can expect color matching to be from a monitor to paper. The ColorMunki? Dismal, to say the least. We tried it a few times, from plain paper, to expensive coated stock. The ColorMunki's results were consistently awful.


It was great for spot color readings, though, so you could get the RGB or *L*a*b values of an object. But then we found other X-Rite software that would let us do the same thing with the i1 Pro 2 and had no reason after that to keep the ColorMunki.
