@pharmacist - thanks for all the additional information; I returned the i1Studio package already back to a friend of mine, he is happy with it but is not using it very frequently, he tells me that he has profiled all the papers already he is using.
This was just a limited exercise; I don't know if there is any improvement with newer software from Calibrite with this type of spectro; the short waiting/drying time recommendation of 10 min is just too short for dye inks anyway, and there are some papers which are more critical than this...
I happened to get access for a short while to an i1Studio spectro, and I ran a few tests with the i1Studio software to create a profile - on the Action glossy paper 210gr. The software splits the action in 2 parts - with 2 patch sheets - the second one for an optimization step. Both patch sheets...
I'm doing the printhead/nozzle flushing in various situations e.g. when I convert back from a pigment ink set to dye inks as I did with various printers like the L1800/L800. I'm using a clear ink - a mix of water and glycoles as a cleaning agent. I only can report that this nozzle flushing works...
There is a driver option which I never tested - it's on the maintenance/service tab hidden in the extended settings - 'Allow applications to perform ICM color matching' at the cursor location , I don't know which difference it makes ; I'm using an older version of Qimage and select the necessary...
I think it's pretty simple - you should print your images with a profile with the same printer/driver settings as you printed the patchsheets during the profiling process - so can actually both
- you print the patchsheet(s) with the driver setting color mgmt/adjustments on and print your...
It's too late - but I only can recommend a potential buyer of an inkjet printer to request an up to date nozzle check and further data - e.g. a status report from WicReset which tells you the number of pages printed and would list recent error conditions.
How did you pay ? - Paypal or credit...
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

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

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...
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

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...
