So is this all rigid substrate?

Well... That's what linearization is for. Sorry. Couldn't resist.

Ohhhhh... I get what you're saying. I actually wrote out a reply and then it dawned on me. Only thing I'd say though is that when you print a sheet, and hold it in your hands and look at it, it was printed with a specific number of dots per inch. So from that standpoint, dpi is a correct term...

I will say that one's pretty far into the weeds if you ask me. In fact I've never had a client even use the term addressability. I haven't even seen "perceived resolution" in years Day-to-day, what I see as the biggest offenders are dpi being used to describe ppi, and the term "profile" having...

High-end high-priced products. They could be exactly what you need... or not. It depends on what you're going to be doing with them. Mike Adams Correct Color

I agree completely, actually. In the videos, I mention that problem. Right now the top of my worst-offender list is the term "greyscale." You may not have seen this, but inkjet printhead and printer manufacturers have co-opted that term to mean multi-dot, calling multi-dot printheads...

Gordo, Well, you caught me using shorthand... again, as I recall. But in the video, I define linearization as, "The process of bringing a printing device into a calibrated state to compensate for dot gain." And on the website, I describe G7 as follows, "What G7 actually is is a...

Just for grins, I downloaded the driver and took a look. 1200F is for fixed dots, and 1200 is for multi-dot. I assume you're saying you have a profile made with the 1200F setting? I couldn't find anything anywhere regarding MAPS2, so that may be something that isn't included in the driver...

No offense taken, I assure you. To answer: Well, if you do G7 correctly, it shouldn't necessarily decrease your gamut. What I meant when talking about leaving gamut on the table is that achieving maximum gamut is not part of the G7 routine. You can G7 a machine, but nothing in the process...

Valerie, In quick answer to your question, everyone in the large format inkjet industry does step-and-repeat or imposition in the RIP. That's why the file has to be created in Illustrator, and it's also essential that your cut file layer use the color name that the RIP will recognize -- the...

If you don't want to wait for the video version: http://correctcolor.org/colorbycorrectcolorvsg7.html That's an excellent suggestion. I wish I'd thought to do that. This was a presentation I originally made to do live, and I'd point out the areas in question. But even then, that would have...

There could be any numbers of causes for this, some of them fixable, some of them not. First, for whatever reasons Mimaki has, they are determined to go to great lengths to persuade their clients to use Rasterlink, to the exclusion of all other RIP's. Myself, I think that's a huge mistake...

After an expenditure of quite a bit of time and energy, here finally it is... A Youtube channel that will be dedicated exclusively to large and grand format inkjet printing. With a take and a perspective unlike anything you've ever seen before. Check it out. And please offer any thoughts you...

Johannes, Well that's a pretty comprehensive list. And a few things. First, I'm not much of a Durst fan. Maybe they've changed things since I last saw one, but when I did last see one, it was indeed a very small gamut machine for the huge money the client paid for it. Main reason was that...

Johannes, If you get the files in any CMYK working space, there's nothing you can do about it. You may as well use them. But the answer is that most large format printers printing on most large format media, and properly profiled, will have a significantly larger color gamut than all the...

Bebris, Yeah. I get that. Still, you need to start with a constant. You say, "Converted to L*a*b* from what? You can't do a conversion from an unknown color space. However, since you think L* 39 a* -0.71 and b* -25.28 are close, we can use them. Using them, my CMYK working space set to...

WC, The HP is a fine machine for doing reasonable commercial quality signage, banner and point of purchase work. You'd be well pleased with it for simple outdoor banners. However, if by "high quality large prints on paper" you mean fine-art type quality on photo-grade stocks, no. It will not...

So, I'm curious... Why are you chasing CMYK values in the first place? The numbers you're using: C99 M60 Y5 K25, where did they come from? What color space? What do they represent? If you know the color space, create them in Photoshop in that colorspace, take the L*a*b* value out of the...

Well, in order to have accuracy between different machines, you have to have profiles for each machine that are accurate characterizations of each machine on each media that you're using. No process will fix that if you don't. Also it's important to note that there are vast differences between...

Lorna, Y'know... Well, yeah... That's to be expected. A different rendering intent will create different color values. That's its job. Man... I can tell you I've been setting up color workflows around the world for over fifteen years and I would never -- and have never -- set up a workflow...
