Change color profil

[Joel]

Hello,

Impossible to save workflow (when I change color profil widget) with the following colorimetric profiles (http://online.picto.fr/supports).

With other laboratories, no problem.

Would you have an explanation ?

Thx.

...but the workflow is present in folder !!

I load this workflow, click on color widget and three messages :

"Little cms: Error #30000 : Read from memory error : Got 0 bytes, block should be of 128 bytes"

Type OK

"Little cms: Error #30000 : Corrupted memory profile"

Type OK

"Little cms: Error #30000 : Output profile cannot be NULL !"

If you have a solution.... ;)

Precision: no problem of conversion if she is realized image by image. On the other hand, PWP6 refuses to work (and down) during the automation in a workflow.

None of the icc profiles works, is it a problem with lcms or not ?

Thank you for your help...

Hi Joel,

I'm not sure if I know the answer, but perhaps you could try setting FILE/COLOUR MANAGEMENT/ COLOUR MANAGEMENT=ENABLED; COLOUR ENGINE=WINDOWS DEFAULT to see if LCMS is at fault?

Hi Maciej,

The problem remains the same !

If you had the possibility of making a test of conversion with one of the Picto's colorimetric icc profiles, just to see if the profile is THE problem...

I am also going to ask this laboratory.

Thank you very much of your answer.

I have done some experiments, I can reproduce the saving error, more on that later, but I can't reproduce the Little cms error messages you have posted, what profile did you use from that website, I have used the very first one.

I have found a saving error with all printer profiles, I have tried the first one on the site Joel posted, my self created printer profiles (made with Spyder Print from Colorvision) and the profiles delivered with my Canon Printer.
They all give a saving error when trying to save the workflow, converting to a Profile like sRGB, WideGamut, AdobeRGB produces no error when saving.
So it seems to be a general problem with saving when using printer profiles.

Dieter,

Thank you for your answer and your tries.

I used the first one also, as well as one of "k3" and "vivera" with the same results.

But I found an "answer" (?).

I used, by modifying them, workflows realized with PWP5 (which I had kept and which works very well). By creating a new workflow since pwp6, I did not meet any problem ! Save workflow and modifying profiles work.

The various versions of lcms are thus maybe the cause ? I don't know...
