I'm getting an ever so slight red-ish tint on my black and white prints. Happens about 50% of the time but can't figure out why. One picture will print perfect B&W, then days later printing same file it has the red tint. Ink tanks are full. Have tried changing the printer properties option to 'Grayscale' but doesn't seem to make any difference on or off.

Printer is Canon Pixma iX6550. Using Canon Photo Glossy II paper, A3. Genuine Canon inks.

Has anyone else experience this? Thanks.

Quite simply it's making 'grey' by mixing the colours in a certain fashion (like a colour TV would for B&W films), and it's (unsurprisingly) got a slight hue as a result of this.

For true B&W / greyscale printing you need a printer that has true grey inks.
I prefer not to think before I speak. I like being just as surprised as everyone else by what comes out of my mouth.

Just as red checker says.

You need specialist inks and you also need everything totally calibrated including individual papers.

Best just to outscource your printer to a professional printer, which does not mean one of the cheap internet ones, as they'll probably supply you the same.

Calibration isn't typically an issue if you're using the printer manufacturer's own papers and inks* as there's a fairly high tolerance with the manufacture of them and they know how they'll behave with one another. IMO, it's not worth bothering with unless you've got something like a 8-12 ink printer and are printing on gallery paper for high-end sale/exhibition. I'll be damned if I can tell the difference when my 6-colour HP printer is calibrated with my Spyder print calibrator and I only ever use HP inks with their genuine (satin) paper.

* - although it is important to select the right papers in the print preferences.

Thanks all. Have also gotten pointers from other Canon users and am experimenting now with tweaking the print output sliders which seems to be helping.

When I had a studio next to a "traditional" ink on paper printers they would adjust the 4 colour presses daily as the weather/humidity/temperature could affect the "colour balance" of a job If I remember correctly greys made the differences most noticable - could be another set of variables to look at.
