Interesting, and I'd say pertinent question. I actually grew up in litho before the days of standards and specifications, and we used to work very hard to be the best printer in not just Dallas, or Texas, or the US, but the world. And to this day I look back and think that maybe for a period of...

I can help. To get to where you need to be, I'd suggest someone who can come to you and train you on what you need to know in your environment. Which, by happy coincidence, is a service I provide. Yes, there is a lot of information available online, but a lot of it is wrong. And a lot of it...

Dot pattern is definitely a profileable (ICC profileable) aspect of machine state. If you want to use a dot pattern for which you have no existing complete media profiles -- including ICC -- then you have to complete the process. --Crash Davis You can think of it that way, and it might even...

Note that the term "profile" in this industry has somewhat of dual meanings. It can either mean a media profile, or it can mean an ICC profile. A media profile defines a device printing in a certain state. That state will typically include media white point, single channel chroma values and ink...

Well, what it sounds like is happening is that you're doing a calibration perhaps in a wrong section or with a technique for making an entirely new media profile. If all you're doing is a "recalibration" then you should be working within a particular media profile and you should not be able to...

I agree completely about Adobe. Here in the US, the equivalent of Forgra 39 is GRACoL 2006. And many of the evangelists of G7 in large format -- a group which most emphatically does not include me -- sing its praises and encourage clients to set it as their incoming CMYK space in their RIP's...

Actually, it wouldn't explain that. Light colors are part of their main color channel with their 'splits' determined by your particular printer profile. Light black and light light black are part of the black channel, light magenta is part of the magenta channel, and light cyan is part of the...

Well since this has fired up again, I'll just add two cents having read along with some interest but not yet weighed in. To me, it seems like a futile effort. I downloaded the thing and had a look awhile back, and yes, it's a big CMYK space. But... So? As far as I can see, it doesn't define...

Curious if you could share the L*a*b* value that gets that particular combination.

Alith Just to amplify, that's not the reason. It's more like a side benefit of doing it right from conception. The problem with the old CMYK values is that, for the very reasons Dov describes, they are useless. You may have gotten results you like on one or more colors, but if you did, that...

Michael, In large format inkjet, you can't do anything without plenty of work tables. Just about everything produced needs to be rolled out on a table for some type of hand finishing. Mike Adams Correct Color

Many lifetimes ago I bought and sold printing equipment for a living. And when I did, occasionally I'd get a call from someone who wanted to open an in-house shop. And I cost myself many sales I'm sure, but every time I did, I told them pretty much the same thing: Look, I know you think...

That is the most likely explanation. And that's a pretty common problem for files that have passed through some internet system. I have yet to meet a guy who designed one of those systems who cared about color or wanted to learn. As far as your printer profile goes, there are actually several...

The "scratched heads from a dirty environment" honestly sounds pretty lame. I've never heard that one before and it'd take some pretty good-sized chunks getting up in there to do it. If it was my machine, I'd run a nozzle check, and then several cleanings to see if I could get all the nozzles...

I'd agree. Then I'd go a bit further and suggest taking those readings, averaging them together for each device, and then comparing the averages. Mike Adams Correct Color

And what I'd explain to you if you were a client and you said that to me -- very patiently -- is that you can't get a CMYK value from an i1Pro2. All it will give you is a L*a*b* value. To get to a CMYK number that L*a*b* value then has to be converted by someone, somehow, into some CMYK color...

No. It is not true. The one unchanging constant in Pantone colors is the ink formulations themselves. Get any formula book, on any stock, from anywhere in the world, and compare the ink formulations, and they'll always be the same. That's what Pantone colors originally were/are: Ink formulas...

I'm saying I guess you could technically call it that, but no one ever does. Typically gamut-mapping is thought of -- at least by me -- as occurring when an actual conversion is made from one profile to another. Soft proofing is a specific term with a specific meaning that I tend to think of as...

Why, thank you, sir.

If you insist. Its just that no one ever calls it that. It's just referred to as soft proofing, because no change is actually made. Yeah, I'm aware. But I'd put my research up against any of theirs. I think there's kind of a cadre of people out there who are so awe-struck by Graeme Gill --and...
