Title: Red color cast
Post by: JoRi on November 03, 2008, 04:14:20 pm
Hi
I have experienced a problem after trying to do color management right.
I have calibrated my LCD - monitor at 6500K and gamma 2.2 with a Spyder Pro 3.
I have made profiles of my printer paper combination with SpyderPrint 3.
After profiling I printed the test image from within SpyderPrint. And it comes out with a nasty red colour cast.
What am I doing wrong? And how do I correct it?
Hope someone out there can help me.

Hi.

Try this: reduce brightness/backlight to 50% and calibrate again (don't use the ambiente light compensation setting). If it doesn't work, try this: calibrate using native white point, but with gamma 2.2.

Most monitors are already calibrated at 6500K, so correcting the gamma (on individual channels) works just fine.

Please let me know if this helps.

BTW, what's the monitor model?

Regards,
Luis

Hi Luis
Thanks. It did at least show me much more red on the monitor, so may be the profiles are ok. The moniter is Samsung SyncMatser 913N.
I will try on of my troublesome pictures with a canned profile AND the one I just made to see if there any differenses.

Jorgen

JoRi,
For what it's worth, an Epson developed work flow says that "If your printed image is lighter than expected and has a strong red cast, you probably turned on color management in both Photoshop and the Epson printer driver."
