I"ll apologize right off the bat. I'm positive this has been discussed before, but I must not be phrasing my quirie correctly. If someone could point me in the correct direction I'd be happy. I've printed in LR since 1.1 and never had the issues that some have had. I print on Mac & Windows - PS & LR with no problems. I'm not sure what will help so I'll throw it all out. I was helping some friends on their machines ( Mac os 10.6 pushing a Canon 9500 printer) the shooter was shooting Jpeg's ( I think with a Canon 1D or 1ds). I could not get my prints to behave. Everything came out Magenta and contrasty. Not the printer profile mismatch magenta, more like the Wrong tag on the file - lobster people - type thing. Printing through PS did not have the issue. Since I did all of the settings, they were the same. I have tried to replicate this back at my computers but everything prints fine. Did I miss something, or is it possible there was a camera issue? Thanks for any help, and again, I apologize for the redundant question. Doug
Could be a double-colour-management issue, i.e. both LR and the printer think they should do the colour control.
If so, you need to check that only one is taking control of colour, preferably LR. There cold be some printer settings which need to be switched off, so that it only lets LR do colour mgmt.
Another possible cause:
You said: " the shooter was shooting Jpeg's".
What was his/her WB setting? Did he/she have Image Enhancements enabled in camera? Any other in-camera settings? High contrast? High saturation?
Have him/her shoot some Raw images and see if the problem persists.
I have no access to the images any more. I try to check WB, but it didn't record. Overall the wb looked rreasonable. I know that sounds strange since also had a strong Magenta cast to the print. Looking back, I forgot to mention that LR & PS both displayed the images fine, its just that LR printed them goofy. Is there a way the camera could have produced an sRGB file but tagged it as Adobe1998? That's almost the look of the prints.
In another thread where the poster reported strong red / magenta colors, Jeff Schewe said that this is an indication for double color management, i.e. Lr manages colors and the printer manages color. Cornelia-I also indicated this as the reason.
So, I would double and triple-check all my print settings in Lr and in the printer dialog to make sure that only one of the two is managing colors.
I'm familiar with that setting issue and its results. This would be like that result, but crank the saturation to about 8 (not quite 11). I checked printer settings multiple times and had no problem with the settings in PS. The only way it could be double management is if there is a problem with the printer driver communicating with LR. With th 9500 and os10.6 PS and LR are supposed to "talk" to the printer driver. So there is no actual "off" on the printer color management. But again, no problems printing through PS.
You know what? This sounds similar to another thread.
But don't let the header of the thread confuse you; scroll down to where he shows his prints that are to light in red/magenta when printed from Lr but are OK when printed from CS6.
His was a Epson 4880 yours is a Canon 9500.
As you'll see on this thread no solution was ever found and the poster gave up eventually saying he would henceforth print from CS6.
The funny thing was though that once he disabled all his presets and plug-ins the Lr print was OK.
Somebody on the other thread mentioned an old print preset (old meaning a preset developed for a different printer if I remember correctly) that could have gone "funny" and did not allow the printer color management to be switched off.
I'm just mentioning this in case it would "ring a bell" with you.
That seems like the right track, and would account for why I can't replicate the results on my computers. I'll see if there are any odd presets or pluggins on the computers. Could be they'll have to re-install LR.
I'll keep researching, but thanks. Yhis sounds Plausable.
