You're misinterpreting my remarks. I would not expect GMI or any brand assurance program change their methodologies because a printer or even a customer thought they knew better how that job should be done. What I said is that the targets are determined by the customer's needs and in agreement...

Also SpotOn Analyze. It doesn't calculate curves like pressSIGN, but you can rough these in manually from the info supplied if you know what you're doing.

Again, if the material prevents you from reaching the target aims there is nothing to be done except get the customer to spec a different board or get them to have GMI alter the aims. Don't tell me that this is immutable: GMI works for your customer, not the other way around. Don't tell me I'm...

I'm probably not the person to ask for the full sales pitch for GMG. I'm sure they'll be happy to fill you in. But I think it would be safe to say that without the OpenColor module ColorProof will struggle like most proofing RIPs with advanced spot color functions such as simulating overprints...

Her is a screenshot of the settings window from pressSIGN.

Paul is exactly right: pressSIGN does not restrict you to any particular print conditions: All targets including white point are editable. This is true whether you build the standard manually, import it as a prebuilt set, or extract it from an ICC profile--there is still that check box in the...

It's not quite that simple. MX4 is a proprietary form of device link profile that connects the reference color space with the printer output space. In most RIPs standard ICC profiles are used in both positions. By itself his has little or nothing to do with proofing spot colors, which is an area...

Errors in profiling have broader effect than on a single color; when that color is a spot color you can be pretty sure that your problem is your input and not your output, specifically in your spot color definition or spot color processing options/settings in your software. Be sure that the...

Well, clearly something went wrong for you--there is no dispute over that. The question is how and why. I should be able to produce a similar result from your Lab value using i1P and I can't, so I would simply say that you've introduced a source of error somewhere. My main point is that it is a...

First of all, if you want anyone to comment in a specific way about your results you need to provide all your data, including especially the settings you used in i1Profiler. (Did you tell us how you made this conversion--in what application? Simply insisting you're right will not advance any...

Let's assume for a moment that your measurement data is fine and you made what looked like a more logical build in another profiling app. The question then might be why there is so little black in your build from i1Profiler. Did you perhaps accidentally alter the black generation setting in i1P...

I need to be clear that my remarks were general ones about the way ICC profiles work, and I would need to see your output (conversion) profile and workflow (including the rendering intent) to begin to understand why a deep violet blue got converted to that particular build. No, it is not normal...

Hi Tim: I haven't looked at Schnitzel's data and have no specific comments to make about it. I would however state again as a general principle that there is no point in second-guessing the logic applied by i1Profiler in making these builds just by looking at these percentages alone. In any...

These questions come up regularly when one works in the realm of multicolor profiling and printing. Unfortunately, accurate information is not always so easy to find. One area of frequent misunderstanding is how multicolor separations are calculated. Output profiles do not, as a rule, impose any...

You're all correct. For proofing you should uncheck the box, as the purpose is to force assignment of the target press profile so the customer knows how the job will print, ugly or beautiful, and so corrective action can be taken in time. Sometimes that action is simply conversion of the file to...
