hi All,

I have tried to remove a magenta cast with the printer filter, setting Red -2 or -10 in white balance.

However, I cannot see any difference.

What could I have done wrong?!

ciao,

The amounts you mention for adjusting in White Balance are very small.
See attached image below that was way out on WB, notice that it required +52 red and -29 Blue to correct it in the editor - quite large numbers!

So to understand your problem correctly, do your images look right on your monitor and only the prints have a magenta cast - or do the images look bad on screen too?

If it's only the prints that have the magenta cast and you are using a monitor and printer profile, I suggest you look for the source of the problem and not try to correct it with a print filter.
There are some possibilities:
1. The printer driver is not set correctly - it should be ICM and "no color adjustment". Tell us what printer you have and the settings being used. Attach some screen shots.
2. Qimage is not set correctly: is the printer profile set and enabled, again, attach a screen shot?
3. This may sound silly but is a common problem - do a nozzle check and make sure the test pattern is complete - a blocked nozzle will affect the colours.
4. Are you using genuine Epson inks: an Epson profile probably will not work with so called "compatible" inks?

Have you saved the filter with a unique name? On your screen shot, the Print Filter box is not ticked. When that is done you will be prompted to select a filter file.

That's good, I have an R800 too and get superb prints that match my monitor extremely well and there's no reason why you should not get the same.
BUT .. have you printed a nozzle check pattern just before you print - look at it carefully, clean until the pattern is perfect, no breaks.
Sorry to go on about it, but I cannot see any other reason for getting a magenta cast on your prints.

No, it should not. Qimage is fully colour management aware. There is a possibility that the image is not tagged in its exif data or the Adobe profile is not embedded.
You can check by hovering you mouse over the thumbnail and read what it says in the exif bar at the bottom of the screen; it's the last item in the data.
If it does not show Adobe RGB and says sRGB, it's as I said not exif tagged or embedded. Yo can override the image icc profile in the filter screen to correct it - near the bottom of the adjust tab.
This is unlikely to give a magenta cast, just make the image look dull overall.

Do you see a difference in the image on screen when you make the filter?
Terry

If the sky is basically neutral then a magenta saturation of -60 probably will not make much difference.
Could you see the difference when using the White Balance changes?
I tried your values here on an image with a grey sky and the difference was considerable. I'm confident enough in my process to know that a print would reflect this.
I see from your screen shot that it is some time since your monitor was calibrated - probably worth doing again. How was this done before?
Terry.

I've e-mailed Gian with my address.

The oldest I have is an old Studio, but fairly certain you have the same interface in PRO
See screen snap.
Open the Editor screen to the tools as shown.
At the bottom of the tool box, you see Pixel Position and Current Color
