I am getting great prints from qimage with perfect color correlation. But most of my prints are darker (more saturated?) than what I see on my screen. Is this to be expected?

I edit in Lightroom. Export 8 bit tiffs to qimage.

Calibrate lcd screen with Huey.

canon pixma 9000 pro

paper is canon photo paper pluss glossy or photo paper pro glossy

Qimage manages color management.

qimage is set for the proper printer and paper profile (profile supplied by canon).

fyi, prints made in Lightroom are also slightly darker.



Any ideas?



Andy

I've seen exactly the same issue with some of my photos. Images with lots of fine detail - a beach covered with small pebbles is a good example - get significantly darkened in some cases. Whether you notice the effect depends on lots of factors. In my case I am very critical if the print is darker than the print preview - so I do't use QImage Pro for such images. Even small amounts of darkening can change the mood of a photo quite significantly. I haven't tried this for some time, but I recall that some QIP sharpening algorithms produce more darkening than others. Of course sharpening works by increasing contrast so some darkening is inevitable, it's just a question of whether it happens in a way that you find (subjectively) intrusive.

Why not try a test print from another application e.g. Photoshop, and compare with the QIP version? It should be apparent whether the print is darker and if so by how much. This will also confirm that your workflow is OK.

Also, try an image with very low levels of detail e.g. large flat areas. If you're seeing the issue I've seen there should be no significant darkening .

Neither Qimage nor sharpening darken photos. Sharpening increases edge contrast which basically amounts to darkening some areas while lightening others, making it a wash in the overall photo. In addition, you can select the amount of sharpening you like in Qimage from none to very sharp. It's your choice. As to prints being dark/light, sounds like a color management issue to me. If you want your prints to match your screen, you'll need to engage color management as that's what it really takes if you want a screen to print match. I've written a number of articles on this issue here at Steve's:

Mike was right for me. My dark prints were a result of a defective monitor calibrator.

My monitor was too light and my prints were coming out too dark.

I bought a new calibrator and have perfectly color managed prints.

A cautionary tale.

Could you recommend a calibrater Andy ?
or anyone else for that matter!

small budget unfortunately but I guess if one has to spend a lot I can save up or something ...
