Hi, what is the way to convert from i1share or profilemaker5 cxf to i1profiler cxf?

I mean I need to make (measure) some patches and import those into i1profiler (as spot colros) in profile optimization?


Thanks.

You should be able to measure these directly inside i1P.

I'm trying to fake some 256 shades of gray, I can't measure them. I need the way to load fake 256 shades of gray.

Depening on what you’re trying to accomplish (optimize gray), the solution is here:

The default working file format for i1profiler is .mxf.

There is no provision for converting .cxf or .txt (cgats) to .mxf under Printer Profile Optimization menu.
Such conversion can be carried out in Printer Profiling.

1) In main menu, select Printer Profiling
2) Skip Patch Set and Test Chart, go direct to Measurement.
3) Select Load and file option Cxf files (*.cxf)
4) Drag your measurement file in Cxf format into the already opened folder and then open it.
5) Save it in .mxf and copy this file to a known folder.
6) Now go to Printer Profile Optimization to load the saved .mxf file from the known folder.

2) Skip Patch Set and Test Chart, go direct to Measurement.
3) Select Load and file option Cxf files (*.cxf)

I select load and then load my CGATS file made by colorlab, then clicking the save button gives this error:
There are no measurements available to save.

4) Drag your measurement file in Cxf format into the already opened folder and then open it.
I only have dummy CGATS file, or cxf v1 made by profilemaker from CGATS file.

5) Save it in .mxf and copy this file to a known folder.
Cant' complete this step
6) Now go to Printer Profile Optimization to load the saved .mxf file from the known folder.
Print optimization supports cxf in spot color menu, the .mxf is a whole patch set.

----------------------------------------------------------------------------

I can open my CGATS file in Printer profiling -> Patch set
Then I click save button and save as .pxf or .cxf
Then I go to profile optimization select my profile to be optimized
If I load the .pxf file the profile is unselected and I must select it again to no avail.
If I load the .cxf file like spot colors I get error: unable to extract colors from file

I still my original question answered but here is a workaround.


You can import CGATS file with 256 grays in colorport and make a target measure it in colorport.
Save as Profilemake CGATS XRGA.

Load the CGATS XRGA file in your i1profiler in printer profiling -> Measurement tab. Click save button save as .mxf to a known folder.
Open Profile optimization and select your profile to be optimized.
Make sure smart patch generator is a at 0, patches from spot colors at 0, patches from image at 0
Go to "Measurement" tab click Load and select your .mxf  file.

Now here is why saving your measurement in colorport v2 in profilemaker5 XRGA important.
If you save in non XRGA format, you will not be able to load measurements in profile optimization.
You will get a pop-up to select your file standard like you get when opening CGATS file in "Printer profiling" - > Measurements tab.

However if you select GMDI GretagMacbeth - you will get pop up (Invalid measurement file.)

This is NONSENSE, X-RITE want to kill Profilemaker5 software line, they want so you can optimize profiles measured with i1Profiler only. We are lucky someone forgot about colorport v2 when making this restriction.

Measuring in i1Profiler is nonsense because of stupid smalled white separators for i1iO targets, inability to measure small targets, colorport can be hacked to measure small targets Smiley

Xrite want us to use isis only???

Smilem,

I have  compared your file 256rgb and the one on http://www.i1upgrades.com/2011/08/how-to-use-the-tc-2502-gray-optimization-chart/. (fantastic info) thank to Digitaldog for the link

The file to load  in iprofiler must have either rgb value and lab value .

Load this file in patch set page  and save  as cxf ( that is version 3 , incompatible with older version).

This file can be used as spot color For optimize profile.

In the same way I can trasform any old ref file to new cxf3 format

Hope this help

http://www.i1upgrades.com - is crap, I emailed them with my questions no answer from them.
I posted comments, they are deleted.

Sure they have made nice optimization chart, but here is my question that was deleted by http://www.i1upgrades.com

If you generate some patches using smart generator, then import gray scale patches (for example my 256). Then you end up with two black, two white patches. Same happens if you inport TC_2502_LAB-GRAY_SCO.

So how the i1profiler deals with these two patches that are the same color?
1. patches are rounded = increase measurement accuracy
2. having more patches = increase measurement error
3. the second patch is excluded from building ICC profile
4. Huh

Now why do http://www.i1upgrades.com delete questions like this??? Go on ask them.

I wish..
I've been up against the same problem.
Pat Herold informed me the Pantone Color Manager exports cxf files I1 will like. I took a look at it and dragging an image generate a very limited number of colors, and the entire thing is very Pantone "centric". Still, it might be made to work, I just ran out of time with it so far.
For my purposes Pantone colors are of little use, measured colors are of little use, I'd prefer to set up my own file or color list of LAB or RGB and be able to format it in a way the optimizer will be happy with.
I can export these a wide variety of ways from a variety of tools, MeasureTool, ColorPort. ColorThink, etc etc.. Also brought into I1 Profiler then exported..
This limitation seems overly proprietory.

I've also used a workflow similar to what you describe. Convoluted, but it seems to work.

The more I use colorport v2 (freeware), the more I've become impressed with it. That is especially true the more I wrestle with PMP5 (and also i1Profiler 1.4.2 [demo]).

I'm also finding colorport to be a decent "front end" for the ArgyllCms freeware to actually generate unrestricted printer profiles. It's very useful with an i1iSis that ArgyllCms otherwise doesn't support "natively".
