Yes, it is possible to assign your own ICC/ICM profile for the copier. In the driver, click the "color management" tab and select "manual".

Then assign is the color profile you wish your machine to use.

I have to point out here that assigning a profile in this way does little to improve the prints from the machine. Changing profiles can only limit the gamut of the output you will recieve, never make it larger.

Let me explain... my 3228 is currently printing 100% of it's possible gamut (total range of colors possible). If I apply a profile that specifies a different range of colors, then my machine can only print those colors that appear in its own natural gamut AND in the profile's gamut. Colors that my 3228 could print before that are not in the gamut are prevented from being printed.

The good news, if I wanted to make my output similar to some machine that had a smaller gamut than my 3228, then limiting the output of the 3228 is the way to do this. If however, my goal is "pleasing color" then I would want my 3228 to have the widest range possible so that it can print as many colors as it can.
Tnx for your reply!

We have tried to use different profiles with the Windows drivers, but we cant see any difference. (In my opinion the quality is super) But, my client wants to adjust fx. gamma for each color in order to match the exact colors. In other words they would like to make their own profiles (I know; within the gamut of the printer)
I've worked with it yesterday and my biggest concern is that I cant seem to find the proper place to put the ICC profile on the Mac. Is there any difference between OS X and OS 9?
Ok... First, you said "PS driver", so I was looking at a PS driver on a PC.

Applying this profile does not in any way help you match exact colors. All that ICC/ICM profiles do is define the Gamut of the printer. All that does is help your driver map colors that are out of gamut into the gamut of the printer.

If you want to apply an ICC profile in OSX, copy your ICC profile to System/Library/Colorsync/Profiles. Then in Printer Manager, click on your printer and click the "Colorsync" icon at the top (colors with a wrench and screwdriver on it). Then, click on "Devices" select your device and apply a new profile by browsing to the directory you placed your ICC profile into. I'm reasonably sure the ICC profile is on the Driver Disk.

If your end goal is for the printer to produce an exact color, such as a pantone color, I'm afraid this won't help you. The only wat to reliably produce a color such as that is with a Fiery and "Spot-On Color" which is included in the Graphic Arts package.
Well, remember that this profile only affects colors that are out of gamut. Perhaps your file only contains color data that is in the printer's Gamut? then you wouldn't see any change in files printed as long as all the colors are within the gamut.

My driver doesn't have a User Settings under CMYK simulation, are you talking about the PC or Mac? (I'm looking at the PC PS driver).

On the PC you cannot change the CMYK simulation (beyond the normal 4 choices), I'll have to look at the Mac driver.

Update: I Looked on the OSX driver and under "Color Profile" it does have a "User Setting". I am sorry to say I'm not sure what this setting would do. However, this box is STILL referring to Colors outside the gamut of the printer. Any changes in color would be slight, if noticable at all.
