Hi Mavtop,
Here is the patch set that is optimized for my 3D-printed slider/ruler for the i1Pro1 and using the famous TC9.18 patch set. It is scrambled and uses 2 sheets of A4 to print (can be easily printed on Letter too, but trimming off the white area around the color patches if needed)...
Is the difference visible in the final printer output using this printer or not and if so can you guide me to your new awk workflow (link ?). Many thanks for your fantastic work you already have done here.
just give it a try: it is very intuitive but sometimes I get a bit confused in which order I have to apply the boolean function (object subject sequence aka is A cutting B or B cutting A).
OK, give it a try Lothman :lol: .....very strange you don't need a referencce chart to calibrate one, even spectro's need a white point to calibrate the first time before scanning the patches.
Well I tried the boolean cutting by defining a empty cylinder (internal diameter 49 mm) and projecting around the cylinder and trying the difference function (boolean modifyer), but somehow the whole upper area is cut leaving only a donut like ring on the bottom :lol: .
I am trying to decrease the base lower (diameter 51.5 mm) into 49 mm with the bolean cut method in Blender, but I have tried several times to do it but it did not managed to decrease the radius of the broad base from 51.5 m to 49 mm base. I tried to decrease the whole from 51.5 to 49 mm, but...
Ink can differ slightly from batch to batch and colour drifting can happen over time. The reason why you will need to calibrate the white point every time before scanning the patches......how do you calibrate a scanner before scanning the patches ???
I am a bit puzzled: how can you know the colors scanned with the ET-8550 is the right one if there is no reference to compare to ?
I had to make a custom scanner target for my Epson ET-8550 with my vintage i1Pro1 and the iMatch software: using a target that I scanned with both the ET-8550 flat...

This would a revolution when we can generate printer profiles without a reference chart and only a software package of $34.95.....
It says even better printer profiles than a hand scanned spectro.....
I repeated the workflow again with Europrint Satin paper with Inktec Powerchrome K3 ink in my Epson P900 using this particular 300-patch ArgyllCMS
I created a printer profile using the same target (a small one on 13x18 cm) for the i1Pro and one on A4 for the CR30 and this is the softproofing...
just leave those settings on standard settings (B2A detail and total ink limit: the last one is for CMYK profiles only and you are going to generate a RGB printer profile).
@x64, @micronica, @crenedecotret : please add extra information to this topic in order to improve this rudimentary how-to manual if I have forgotten something or made a mistake.
To pick up the first post I will now show you how to use the CR30 dispensary.
Thanks to @crenedecotret efforts to make a special randomizing ti1/pxf-file generator I managed to make a new 300 patch target for the CR30 which is finally randomized (in order to get a sharp in color/hue between...
Well actually my first impression is that the 300 patch ArgyllCMS/CR30-target (a single sheet of A4) is comparable to the X-Rite i1Studio 50 + 2x50 BW neutralising method (the version you are using the second patch series grey/near neutral steps to neutralise BW printing in color images). I am...
To answer your questions: yes the device is very good as well as the generated profiles. It has been crossed checked by another member at dpreview comparing it with his i1Pro1 device. I have the i1Pro1 and i1Pro2 to compare the generated profiles using the same patch set (ArgyllCMS) and it does...
