output device profile

[Gerhard Hoogterp]

Hi,

I try to get soft-proofing working on my digikam (version 4.12) and seem to be
stuck. For soft-proofing  digikam wants an output device profile, but the
selectionbox for this profile is grayed out.

There are profiles available (and installed for the monitor and workspace)
which area selectable without problems. But not so for the output.

Documentation available seems to be outdated and didn't show anything besides
an outdated image from a previous color management installation window telling
me to select the right profiles.

Any help?
Thanks!
  Gerhard

Hallo Gerhard,

if I'm right you have already a color printer. In fact you have also already
choosen your sort(s) of printing sheets, all you have to do is downloading
the
matching icc-profile provided by the paper manufacturer. Matching means
matching the combination of paper and printer.
Feeding aunt google with "photo paper icc" will be a good start.

For playing around to understand the workflow, you can use every printer-icc-
package provided by your Linux distribution. The paketmanager should all do
to
the right place. DigiKam will find it and should present the profiles for
selection.

Regards

Jürgen

yeah, I was that far.. my system has all kinds of ICC files. The problem is
that the choice for an output profile is grayed out and not available.

So OR the profiles are not where digikam is expecting them for output devices
(But they are in the folders where digikam says its searching)
OR I'm missing something else..

Again, choosing my display profile is no problem, neither is the camera
profile. It's just the output device who doesn't want to play ball..

Is your output device profile an RGB profile or a CMYK profile? These
days not all printers use CMYK profiles. The last I checked (a long time
ago), digiKam only allowed to select CMYK profiles as output profiles.

Hi,

My printer is a cheapish epson stylus printer. But it's not as much for
printing as for soft-proofing photo's before I send them off.

But then again, digikam looking for CMYK profiles could be the problem. Until
now I had mostly display ICC's not thinking digikam would be smart enough to
actually know the difference (and besides, my output could be a special
display.. ) so I expected the general bunch of ICC files to show up.
But if that's already an issue, then I will have to find printer files first..

Thanks!

https://www.drycreekphoto.com/icc/ provides printer profiles for a
variety of commercial printers (Costco and such) who make photographic
prints. Many establishments that make photographic prints have download
links for their printer-paper combinations right on their websites. And
you can find various printer profiles for various high and mid-range
photographic "printer paper combinations" for download from the internet
(for example do a search for Museo Portfolio paper and an Epson
printer). Most/all of these profiles are RGB profiles.

Does anyone on this list use digiKam for soft proofing? The last I
checked, digiKam didn't seem to work very well for this purpose.
Cinepaint (which probably nobody can compile any more) had great soft
proofing capabilities. GIMP 2.8's capabilities are not too bad. GIMP 2.9
soft proofing is a little bit better than 2.8, as it finally provides
black point compensation.

Thanks..

By now I was able to select a printer profile and I found a profile for the
paper the printing company uses.
But in the end I don't really see any real difference in the soft-proof. A tad
darker, but that's it while the prints were a lot darker and lacking sparkle.
The reason I started with this whole thing anyhow..

I'm also somewhat disappointed in the whole colormanagement under KDE. I found
messages from developers pushing colord and uyranos as solutions for kde. Fast
forward till now,  Uyranos isn't available for the latest kubuntu lacking a
needed lib and while colord is intergrated, the whole userinterface under
kubuntu is basically a colord-kde-icc-manager commandline tool.  

I do remember an plugin for the kde systemsettings and I see references and
screendumps online, but nothing to install or download.

For softproof one has to depend on the applications like gimp and digikam. For
the printer itself I didn't find anything yet. CUPS doesn't seem to have any
settings but then again I would have to find ICC's for my Epson.. I did find a
dmg file which was supposed to have these profiles, but after extracting it
there were only empty folders.. not an ICC in sight..

All in all not exactly a lot of advancement since 2012 and definitely a lot
more complicated than it should be.

But I keep on trying.. starting with creating a new profile for my screen
using my colorhug. As it has been some time I'm sure my current profile isn't
correct anymore so that should be a good start.

Thanks for everybody helping out!
Gerhard
