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...

I did another test and compared a print done with a profile with 165 color patches vs. a print with a profile with 2880 patches, printed on a ET-8550 with 106 Epson inks and the Ultragrossy standard driver setting , with rel col. rendering intent and BPC off. The test print covers all colors -...

You may try to compare prints done either with an ArgyllCMS profile or an i1Profiler or ColorMunki or .... profile generator, but be aware that every company has some room for variations how rendering intents are implemented - it would be the perceptuakl or the relative colorimetric mode...

I only can confirm @pharmacist 's findings above with a test I did on his previous patch sheet version with 154 patches - this shows that a pretty good profile is possible with such a low patch count.

Canon printheads have separate nozzle rows for different droplet sizes - Epson does not need that and operates with variable droplet sizes, explains the higher number of nozzles for comparable Canon vs. Epson printheads. Epson longer time ago published a description what is happening inside the...

Download of the last i1Prifler version supporting the original i1Pro spectro is possible here - PC or Mac version https://xritephoto.com/ph_product_overview.aspx?ID=2630&Action=Support&SoftwareID=2107 The actual spectro acts as license dongle on XRite software, licence data can be transferred...

I made another test to compare profiles with based on different patch sheet counts and the impact onto actual prints. I did this - - I created several icc-profiles with 96 - 283 -720 - 1440 - 2880 color patches onto the same paper type, a glossy cast coated 210 gr paper by the Action thrift...
