Re: Grey prints Green on Canon Pixma Pro-100 - HELP!

Your printer has two black inks. A pigment black for text and a black (along with cyan, magenta and yellow) for photos. 

 

You should ryn a nozzle check check and if necessary a head cleaning.

Re: Grey prints Green on Canon Pixma Pro-100 - HELP!

Hey, thanks for getting back to me! It's a 2019 MacBook running Catalina and I usually print from Lightroom CC Classic but same problem from Photoshop as I recall. I use Red River Papers with the proper profiles And like the other people the gray-as-green-tinted problem started up out of nowhere. I saw someone mention it being fixed by choosing "Photo Paper Plus Semi-Gloss" but it seems weird that that would be the only paper that solved the problem. (And not to complicate this further, but I often find that whatever option I choose in that "Quality & Media" window doesn't "stick"--will revert back to another Canon option as soon as I leave the Print Settings dialogue.

Re: Grey prints Green on Canon Pixma Pro-100 - HELP!

I was about to go back through the thread to find the instructions for running a nozzle check and perhaps a head cleaning, but it sounds more like a software issue considering that everyone seems to have a problem with the exact same color cast, no? Thanks again!

Nozzle check looked fine, FYI.

Hi Karl.

 

I ran a test print using Red River SemiGloss Fiber. ICC profile from RR; recomended media type Canon Photo Paper Pro Luster.

 

Test image was a B&W test print from Northlight Images.

 

Printer driver is latest download from Canon site - 16.40.1.0 version.

 

Screenshots of settings in LR and printer driver.

No color cast. Excellent B&W print.

 

You say it started up out of nowhere - where there any system changes to your computer?

"I usually print from Lightroom CC Classic but same problem from Photoshop..."

 

I see this problem a lot of the time when doing B&W.  Mine tends to have a very slight magenta cast. I also exclusively use PS to print with. Sometimes you can't believe what you are seeing on your monitor. In PS you can adjust indivual colors if need be.  I don't know it the Pro-100 will ever or can ever do true B&W prints but you can get close. For it to do B&W it needs all the cartridges even the color cartridges.  There is no possibile way to get 256 shades of grey with one or two B&W ink cartridges. In your case it appeares green is mor eheavy that it should be. Try adjusting it in PS.  You are letting PS mangae the printer.  Never let the printer manage printing.

 

Just some suggestions. Hope it helps you.

Re: Grey prints Green on Canon Pixma Pro-100 - HELP!

1. I’m looking at a Pro-100 B&W print with no color cast.

2. The Pro-100 has Black, Gray and Light Gray inks.

3. When printing monochrome it is very important to avoid papers with optical brightening agents (OBAs). They react to the light source and produce different color casts depending on the light type.

Top point!

"When printing monochrome it is very important to avoid papers with optical brightening agents (OBAs)."

 

This is super important.  The selection of paper is paramount.  If you call Red River, they will recommend their best papers for B&W prints.
