Lightroom Classic CC - Magenta Problem

[alickm9508967]

Hope someone can help.

First up, my screen is calibrated, I have reset Lightroom, I have updated my Canon drivers. I have Lightroom also running on a Mac and it prints the colours correctly.

I am running a Windows 10 system with a Canon iP8700 series printer. The problem started around a month ago.

When I print out, I have a heavy magenta cast. I also see the cast in the print preview so I have stopped printing and am checking various settings against the preview.

The problem remains the same regardless of whether I use the Profile setting Managed by Printer or the Canon presets.

If I print to jpeg file instead of printer then it prints correctly.

I can do a manual colour adjustment on the preview to reduce the magenta.

Any ideas why this has started happening and how to correct it. I have tried pretty much every option available.

Thanks!

Forgot to add, if I try to print from Photoshop I see the say cast in the preview.

I presume your printer profile for the paper you are using is not very good. You need to get a better printer profile.

Thanks for answering. Worked perfectly until one month ago (printer two years old), profiles are standard Canon. When I print to jpeg using the profile it works fine.

A magenta cast is usually caused by managing colour both in the printer and in Lightroom. Make sure you aren't doing that.

[alickm9508967]

Yes, confirmed I am not doing that.

I do have exactly the same problem with a Canon ip7250 printer.

Printing to JPEG from LR is OK.

When opening this JPEG in PS it is OK.

When switching Print Preview in PS to Managed by PS it gets the Magenta cast.

Managed by Printer it is OK.

It started also a few weeks ago.

WIN 10 using latest XPS drivers for Canon Pixma iP7250.

So you're not alone.

Thanks for the reply! Let's see if anyone has a solution!

Try unticking the print preview box and then rebooting. There seems to be a bug in the latest Canon driver.

Thanks for the reply. Tried that, it did not solve the problem, indeed I didn't use the preview box until I had got fed up wasting printer paper!

My issue has been with a Canon Pixma MG7720 and also just started to happen.  I get magenta in the super dark areas instead of black.  I've tried just about everything - reinstalled Lightroom - the printer twice.  It just started happening.  My issue does not show up in the preview box.  I've wasted a bunch of photo paper on this.

Have you done a nozzle check on printer? Have you done the canon calibration procedure? Canon has free support. It sounds like a printer issue. Canon printer support (800) 423-2366

A deep cleaning - actually 2 solved this issue.  Thanks.

I have had similar printing problems for years and I've been through everything I could think of:

• checked the Photoshop print settings to make sure there was no clash in colour management between PS and printer;
• went through copious amount of ink cleaning the nozzles;
• calibrated the monitor;
• checked to ensure that I had the correct printer profile for the Ilford paper I like to use;
• turned off print preview;
• even took some lessons from an expert in calibrating computers and printers.

Yet still the problem persisted.  Eventually gave up photo printing, which in turn stuffed up the photo printer (an Epson R800) because of lack of use.  Some time later, after I'd disposed of the printer, I discovered that the computer's graphics card wasn't working.  Aha! I thought.  Bought a new card but didn't get around to buying a new photo printer until very recently (an Epson Surecolor P600).    With much anticipation, I printed my first image.  Imagine my dismay - the magenta cast was still there.   Checked the Photoshop print settings - these were exactly as they should be, set for the printer profile newly downloaded from Ilford.  Felt very glum, indeed.

Now, since 2012 when I started using Lightroom as well as Photoshop, my normal workflow has been to import images into Lightroom, do preliminary adjustments, then edit further in Photoshop.  Then I print (or try to print) images through Photoshop.  But with the cast problem still there, I decided this time to try printing from Lightroom.  No difference.  Then I looked more closely at the Lightroom printer settings.  Good grief - they were set to allow the printer to manage colours.  Because I usually print from Photoshop, I'd never looked at these settings before.  So I corrected the printer settings in Lightroom and - OMG - perfect print!!!!  I then printed from Photoshop, using a different photo but now with the Lightroom and Photoshop print settings set correctly.  Again, a perfect print.

So, I can only assume that Lightroom embeds print instructions into the images that are imported into it, regardless of whether the LR print facility is used, and that these embedded instructions are then not overwritten by Photoshop but sit alongside any Photoshop print choices that you make.    And the result?   A clash of colour management instructions and that nasty, nasty magenta cast.

So, to conclude this long-winded story:  if you use both LR and PS, make sure both have the correct printer settings, regardless of which program you print from.

OK. I have/had the same identical problem. I too have a Canon iP8700 and have the magenta problem in the preview in Lightroom 6. I found that if I use the WS printer,  i.e. Canon iP8700 series WS, and set the Color Management to Manage by Printer (in LR6 Print mode) I get appropriately colored previews and prints. Because the preview is magenta skewed the problem is in the system and not with nozzles or ink or paper, etc.

I hope this helps you.
