Anyhow, I am getting the most consistent results with Qimage. In fact I find it a brilliant Program.
So I have this film neg I scanned, then color matched it to a lab print, then printed with Qimage and the paper profile and it came out indistinguishable from the lab image. Since I was feeling pretty cocky that I got it all figured out, I printed a few more images and they nailed what I saw on screen. So my wife has me print one of her images and it is off....shifted to red etc. What would cause an image to print off when other prints are nailing my calibrated monitor?

Hi, Glad to hear you are enjoying the benefits of using QU  What would cause an image to print off when other prints are nailing my calibrated monitor? Assuming you are using the same paper and printer profile then one of the most common causes reported on this forum of an unexpected colour shift is a blocked printer nozzle. I suggest you do a nozzle check from your driver, run the cleaning cycle, and make sure the nozzle check print is perfect. Other than that, double check all your settings, QU and driver. Terry |

So my wife has me print one of her images and it is off. Terry will be out for a while, so for the sake of saving time, could you send me the image file? I can get it to Terry too. If the file size is too large to email, use a free service called WETRANSFER. https://www.wetransfer.com/My email address is wathree.ssz@verizon.netFred |

Ok.....a little more info, which basically shows I have no idea what I am doing.
Re: The image that shifted to red that I sent to Fred. If I open the image and edit in Qimage, adjust the red channel in curves to Out=188, then save that as a separate image and print it, it nails the original on screen image. And I noticed that the images that printed correctly had blue as the overall color and would not need this adjusting in Qimage.
I hope the makes since.

I hope the makes since. Was just about to email back your image pretty well fixed. The problem was that the red channel is blown out all throughout. Was the original a RAW image? This was a TIF you sent me. Anyway, I poked around until I found a section (back near the water Faucet ) sort of a silver gray block. Bang! White Balance acceptable. I tweaked it manually after that, and it looks OK now... Will send back a JPG via email. ... and don't worry about what you know or don't know.... you will pick it all up quickly. We all had to learn it at one time. Fred |

Hi Screwdriver, The problem was that the red channel is blown out all throughout. Fred passed your image along to me and I would confirm that was the problem and a white balance correction did the trick. It looked like the photo was taken under artificial light with the camera set for daylight. Something to look out for in future. If you shoot in raw, it's easily corrected; white balance correction is the first thing I do when refining raw images with QU. Terry |

It was an abandoned house in Salton Sea, CA and had no electricity. Here is a wider shot of the same scene. But flashed was used in this shot. My issue I am having is that some images print as seen on screen, yet others, especially if they have many red items etc, print with an even more pronounced red cast and white items will turn a little pinkish. Outdoor scenes with blues, greens, browns print almost exactly as shown on screen. I am understanding that images that have many reds in it just need more tweaking for the final print to match how the image was edited and approved. Using curves, turning down the red channel in the printer driver seems to correct the issue.  |

You need to learn to use White Balance... a tool in Qimage which is easy. Are your shots in RAW mode or JPG? Either mode, you need to do a White balance. It is not a problem item. It is a function of the camera misreading the color temperature of the light, whether it is from a window or a flash... The flash adds blue so that countered the red... You should look at the color temp setting on your camera.... set for AUTO WB? Set for outdoors (I'll bet yes)... regardless, none is perfect anyway, so incorporate a one click White balance into your image editing. Fred |

Hi, You said in your previous un-edited post: I personally think it has to do with the printer driver since others I have found searching on the web are experiencing the same thing, same printer. I have heard that some Canon printers have a tendency to red-shift if not using Canon paper. However, if using colour management properly, with a good profile, I don't there should be a problem. I t would be interesting to see screen shots of your QU settings - Job properties, the Canon Driver settings and the paper and profile details. Terry |
