My wife and I have always sent our images out for printing. We just bought a Canon Pro-100, which has tanks dedicated for B&W, in order to do some printing at home. What would be the proper way to print a B&W image so as not to get a color cast? Last night I bought Qimage Ultimate because of the great reviews, but used Paint Shop Pro to print before. I had an image that was greyscale and printed correct in PSP, but when printing with the same settings in Qimage I ended up with a very slight cyan cast. The original image was a Tiff....shown below is a resized jpg. I used the proper ICC profile for printer and paper and turned off color management in the Canon driver. Paper is Canson PhotoSatin Premium RC.

Thanks in advanced!

Hi,
Welcome to the forum and the world of Qimage Ultimate.
Some information from you please.
Would you show some screen shots please:
The Qimage Job Properties.
The Canon Driver settings.
See attached for the QU Job properties (not a Canon printer)
and a Canon driver but not your paper.
Both set correctly for Colour management.
If we can see you versions, we can comment.
The driver should be set from within QU and those settings will be remembered by QU and can be saved as Printer set up.

I occasionally print B&W with different papers and an appropriate printer profile and get good neutral results using QU and a profile made for colour prints.
QU should give the same results as other colour management aware applications, certainly for colour prints. The usual reason for a difference is something not set correctly.
One other thing to check is that nozzles are not blocked, a common cause of "colour" distortion; do a nozzle check and clean if required.
Do the special ink cartridges for B&W have to be made active in any way and if so, was the profile made with that in mind?

I found this:
Maybe it will shed some light.

For the first time, Canon has included gray and light gray inks in a PRO level dye based printer. In combination with black, these two new tanks greatly help the B&W output of the PRO-100. Another first is detailed printer driver control of grayscale output. Our tests consisted of printing the 8x10 test print (shown above) using the driver B&W feature. Photoshop was set to Printer Manages Color and no adjustments were made to the target file. We printed the target using the default, Cool Tone, and Warm Tone settings. After drying for eight hours the prints were evaluated under balanced Solux light.

Neutral - neutral grays with little or no color cast
Cool Tone - a very slight shift to blue and a cooler look
Warm Tone - a light but noticeable warm shift with a slight yellow tone

Tone can also be controlled via X and Y variables, slider bars, or by placing your mouse inside the Tone box.

Brightness settings include normal, light and dark. Intensity and contrast are sliders allowing for finer adjustments.

All of these adjustments will be "previewed" using a standardized sample image. The drop down menu below the pencil photo at right allows you to choose different preview samples. What actually happens on your printed image may be different. We suggest being judicious with changes and make small test prints when getting started.

Overall we were pleased with the results. You will benefit from well prepared files, which means proper exposure as well as some additional mid-tone contrast. Both are helpful in adding the proper amount of intensity and life into a black & white print.

There seems to be a tweaker for COOL or warm...

Screens of my settings below....

Now I took some advice on an older thread on dpreview. so I followed their advice and turned off color handling by Qimage and using the printer settings and the image came out correctly. Just a learning curve I guess.....

This is kinda what I found out....Found it weird that Paint Shop Pro with same ICC and color handling shut off in the printer drivers produced a correct B&W. Anyhow, Qimage blows away PSP and Lightroom in printing in general, so I am glad I bought it.

Thanks all for the help!
