Yes indeed. Setting the ink limits is something of an art though. If you look at the trajectory of raw individual colorants in L*a*b* space, they typically start OK from white, but then compress and curve as they approach their maximums. Typically they end up curling back from some peak density. Dot gain can be extreme. In some printing modes, a single channel 100% can correspond to 400% ink on paper or more due to dot overlap. So a tradeoff with gamut is how much ink you are putting on the page, and whether this will run, or clog detail or take too long to dry, or result in some other undesirable artifact, such as yellow floating to the top etc.

Thank you!

Canon in its Media Configuration Tool includes a procedure to determine the ink limit for a custom media type. It is a file which the user has the option to print and check it visually during the setup of the custom media type:

"missing leading line and central composition. " quote Les

You clearly missed the artist statement en verso: "First wife in long sleeved sweater pointing in the direction from which wife number two arrived."
As by his own statement she is properly positioned off to the left casting her arm with flowing sleeve across the page and into some past and future. Quite modern in concept.

Don't downsample - set your output resolution to 300 dpi (Canon printers) or 360 dpi (Epson printers) unless you have more resolution than that in the original image. If your original resolution is higher than that at your output size, set output resolution to 600 dpi (Canon) or 720 dpi (Epson).

The Epson SC-P10000/P20000 are 600 DPI units, unlike earlier Epson models. Technically, all Epson MicroTFP models are 600, but aside from the P10K/P20K, users here are unlikely to encounter other MicroTFP models - for example, we are unlikely to have any SurePress L-6034VW (MSRP US $550,000) users here.  ;D

You two seem to overlook the context I said that: single line animals. Even more complex drawings and paintings by Picasso do not require great skills. They do require a concept, vision, idea, etc. Things that make contemporary art art.



Picasso was lucky to have sold that piece.
Today, any self-respecting curator or a competition judge would reject it because of missing leading line and central composition.

I've included the CC iSis target file I use to check color accuracy. It's in Adobe RGB and is a 16 bit tif. Also included is the RGB CGATs file that can be loaded into I1Profiler's patches as well as the spectro scan from the printed file.

The three are zipped and attached. The file should be printed at 100% using standard color management and selecting Abs. Col. intent. It can be used with any paper/printer/profile. Even without a spectro it's useful for comparing to a real Colorchecker for gross error. With an I1 Pro one can spot read each of the 24 colors. But it's ideal for reading with an iSis though you may need a little work in Excel or MATLAB (What I use) to accumulate and get the stats.

Thanks!

Reading your comments and GWGills' above regarding maximum density I wonder if the ink limit setting of a media type plays a role in gamut volume. If you examine the characteristics of the media types with MCT you will notice various settings on ink upper limit such as ...Standard/Medium/MediumHigh/Highest etc.

Does anyone know of an Adobe/Lr website to suggest adding lens profiles?

Thanks in advance!

It's an oxymoron. Any liberals who get a taste of Soviet measures or connections stop being liberal.

Remember when our extended families used to force us to endure several hours of their slides, "How we spent our summer" ?

This sir is not that experience. They would have needed to kick me out for wanting to go back over, pause, linger, and look again. A real nice treat, thank you for the travels.
