Not directly, there is no profile editor to do that. A profile typically consists of a data matrix of 33x33x33 or 17x17x17 data points, this data grid is independend of the number of color patches which get scanned as the first step. The size of a profile does not change if you enter the data...

I found quite an interesting article about the neutrality of grays https://www.nazdar.com/Portals/0/NewsItems/Articles/ThePowerOfNeutralGray-MikeRuff.pdf

I tried the optimization function of the i1Profiler software only once long time ago, I cannot judge if profiles are getting better that way or running just one cycle with the double number of patch colors at one time. I typically let patch sheet prints dry overnight since the colors of such...

' If you are not faint-hearted you can sell the included dye ink bottles and use that money to buy some good pigment ink (type Precisioncolors' Precisioncolors specifically supports pigment inks for the ET_8550 and gives tips https://precisioncolors.com/ET8550.html Pigment ink effects like...

The darker ranges of the image just disappear in the dark, I'm not familiar with the specifics of the QTR method and why a separate linearization is apparently needed. Do you have the means to create a B/W profile in another way - ColorMunki or i1Match or ...- and compare the print outputs with...

Do you have some function available like the Black Point Compensation - BPC - routine for B/W prints ?

I'm reaching the limits of data accuracy and validity with the current setup; let me just show you what is happening; I printed the 0192 patchsheet, created a profile from it , reprinted the 0192 patchsheet with this profile and scanned it twice - directly one after the other and let i1Profiler...

I checked already the TC2.83 patch sheet https://www.printerknowledge.com/threads/how-many-color-patches-are-needed-for-a-good-profile.16935/post-144751 The Delta to profiles based on higher patch counts is very small and adding a few control points does not make a difference as long as...

the successor of the Pro-10 would be the Pro-300 or the Pro-310 as the newest model. You should look for a printer model which use a user replaceable maintenance/waste ink box. When buying a used unit the waste ink box may already be filled to a degree and you either need to go for a service...

I'm not using 5x7 inch cards, and I'm quite happy with a patch sheet with 283 patches on A5; I don't think I need an upgrade here at this time. That was an import of a standard profile of the old ProfileMaker package. I remember from longer time ago that missing separation bars were impacting...

I appreciate the optimization of the 10x15 cm patch sheet to 192 active patches very much, but I actually don't really need much more of that with higher patch counts. You may have a look to some improvement for user doing the manual scan with the original scanning board - e.g. larger patches or...

Let me mention the DeltaE numbers of the last test - I did in this case compare the patch prints done with the 720 patch profile and the 192 patch profile - on the Netbit paper - it is 1.3. There was a problem with the prints on the Action paper - there was a defect spot in the coating on one...

You may have a look to the ET-8550 - a dye ink printer as an ink tank model and a user replaceable waste ink/maintenance box. Even the OEM inks in bottles are very affordable, or you may use inks by pecisioncolors or other suppliers. But when it comes to longevity - only OEM inks - Claria by...

I assume that you are looking for a 13" printer if you refer to large format. ? I'm not aware of evidence that an Epson printer would clog earlier and/or stronger than a Canon printer, the best maintenance for a printer is printing - on a low level even if you don't have actual printjobs. Just...

I expect a marginal change for the DeltaE 165 vs. 192 - value only - in the range of reading noise/variations behind the decimal point. Let me see.

@pharmasist - it works - I printed your 192 patchsheet on a 10x15 cm card and scanned it with the i1io2 robot - it works !!! - that was some great work you did to create the necessary parameter files and patch sheet.

You got it - it's 192 different colors

PaintShop just gives me the number of unique colors - nothing more - no value or location in an image file whatever. But I could find a way to export the patch file data from the i1Profiler editor as a tab separated text file with the RGB values but again no location data within the patch sheet...

Did you check if you have some dublettes with the same gray value along the gray axis - your standard 5x5x5 matrix of control points already places 5 control points along the gray axis - the mid points - with the 0 - 25 - 50 - 75 - 100 % luminance value - strict gray - a=0 b=0 which may overlap...

the test with a 096 patch profile delivered a deltaE of 1.4 vs. the high patch count - 2880 profile which is slightly wider than the DeltaE of 1.18 with 165 patches , the increase of patches from 96 to 165 patches for profiling delivers a measurable improvement reducing the deltaE...
