There is a problem for quite a number of users of the popular Lightroom package - BPC is always on in Lightroom for the perceptual rendering intent , you find quite some postings to this problem in luminous-landscape.com or dpreview.com and at plenty other postings like here...

What format are you planning to print ? And how many pages per printjob ? Do you plan to print double-sided ? I would not try to print on sheet paper , that will cause too many feeding problems, it is the pickup roller which pushes the sheet to the rollers before the print path, and there is...

Or you use a program like Fineprint which acts like a virtual printer and allows you to use several settings for book(let) printing. You print first to the Fineprint driver, adjust the settings and print from Fineprint to your actual printer. I have seen other utilities for book(let) printing...

Please be aware that this might not an issue of the inks but of an non-matching icc-profile. Every ink/paper/printer combination requires specific color adjustment settings - you may use color adjustments via the driver - or get specific icc-color profiles created by a service provider or you...

That's some unqualified hearsay, Epson and Canon or HP are supplying plenty of profiles with their printers, and all are supposed to produce the same color output with these profiles, and that's thausends and millions of printers. But you need to assume as well that there is some variation...

I think lthis case is closed for me at this point, we have discussed the differences in quite some detail, and it is now up to you - @lmylm - to make it working for you and what you expect from a profile - within the constraints of the available programs.

The black level as stored in the profile data is the actual value as measured during the scanning process, it's a kind of raw data, and this black is not neutral but depends on the ink/paper combination actually measured. The neutral black is the point where the vertical neutral gray/L* axis...

This is a look to some of the profile data, the icc-profile is created along the standardized icc-rules, a file header contains various parameters like the black point - or the white point, the black point is displayed in various colorimetric formats and is the value you gathered from your...

That's a kind of similar situation which got discussed here longer time ago with Dataco...profiles in combination with Photoshop Elements causing as well elevated blacks in softproof mode and in print. It took a while to find out that BPC is always on with the perceptual rendering intent in PS...

Product numbers for Epson products vary by business region , for printers and inks etc, the same ink as well may have different numbers, the bottle heads may even be coded differently - and the bottles having a different price - this to reduce cross border business e.g. Western vs. Eastern...

Why are you looking for a 'better' ink for the ET18100 - specifically which property is of concern ? The ET18100 is a very good printer and the inks as well. I would not exchange inks between these printers ET-7750 or ET-8500 or ET-18100.

Do you have any documented evidence for that ? The icc-profile is a set of data tables + some misc parameters but is not any active program code which does anything on its own ; I don't see that this was understood differently. The actual approach by ArgyllCMS is causing issues for the user -...

lots of these photographers will use glossy papers which have a much lower black level - probably in the range of L=+-3 , and even if ArgyllCMs would raise the level by 50% to 5 about nobody would recognize it unless you remeasure the blacks in a profiled print. And other photographers may use...

Here is my last curve - the gray level response for the 480target profile - it reads out a blacklevel of 18.7 as embedded in the profile header data. The diagram with the perceptual rendering intent with BPC on shows this - the curve starts at a black level of about 34 - a dramatic increase of...

Let me first wish you a quick recovery from your sickness; please be aware that ArgyllCMS is raising the blacklevel for a profile with rel. col. intent and BPC on, exactly tlhis was already discussed in the thread a year ago, and as well with the author of ArgyllCMS, and there is a related...

@lmylm - I think we can conclude your inquiry at tlhis state , there are some issues with ArgyllCMS which you got into. They relate to the use of the BPC - black point compensation - function which interferes to a degree with the perceptual rendering intent, and as well profiling of papers with...

You may review this thread which is quite lengthy and from about a year ago - it deals with about the same problem as yours https://www.printerknowledge.com/threads/argyllcms-profiles-black-point-compensation-gives-composite-black-when-checked.15740/page-5#post-138240

Thanks for the data - what is the type of paper you profiled in this case ? Do you have a profile created with ColorMunki or ccStudio which can be used for comparison and the readout of the blacklevel .? @pharmacist is referring to some issues with the BPC option , here is a plot of the...
