Lr lighter prints
« on: December 13, 2018, 10:46:16 pm »

It used to be that people complained that their prints were darker than their screen renderings. That was usually due to over-bright displays.

Now... I may be wrong, but I am finding that prints are actually lighter than they used to be. Twice using different printers I find that my prints out of Lr 8.0 and 8.1 are slightly lighter than my screen. Nothing changed on my hardware side.

I can easily compensate that by using a small (-5) brightness adjustment in Lr's Print module.

Comments?

well, something changed. maybe the lights you used to view the prints, the display itself, the video card, different computer, maybe something else in your environment.

I think a better solution is to adjust the display brightness until it matches again. Whatever caused the change, you adjust for it.  It’s not uncommon to have to make minor adjustments to the display over time.

I said i might be wrong, but I see nothing changed on my side, other than a new OS (Mojave) and Lr 8.x.

Anyone running Mojave and Lr 8.1 see anything different re print brightness?

If you read Alain Briot's last Part 7 of his article you will see he adds +10 in the print brightness.

With my Epson 3880 I add +20.  Your screen may be right. Just your printer needs this tweak.

This is not good colour management practice. What Wayne suggested is the correct approach.

What? There's no reason to futz with that hack and lots of reasons not to (for one, any other application will print the same RGB values differently). Anyone serious about color management and consistency would never use this silly slider and instead, calibrate the display properly.

I use Mojave and now LR 8.1. Note that Mojave installs a setting to automatically adjust the display brightness according to the ambient light. That could be the source of your issue. That feature needs to be disabled in preferences.

How does it know the ambient light level?

Add me to that... that's why I made my somewhat flabbergasted comment upon reading Alain's article.  Now we have Saiguy chipping in with "sharing that sound advice" here in this thread. 

LULA "appears" to be going backwards.  Maybe next we could have Gary Fong do an article on sRGB as the preferred and only proper color working space!   ;D

Using the monitor’s front camera, I guess. I have the 27 inch iMac retina and that has the camera/sensor.

Andrew,

Sure, why not?  ;D  We've not had a good donnybrook in a while.  You get ready to do battle with the forces of evil!  I'll make some popcorn and settle in to watch!

so perhaps only affects iMacs and MacPro’s?

of note, there has been some discussion on Mojave affecting the printed output in a negative way. I myself had this issue, and the only fix for me was to uninstall all Epson drivers and reinstall them. I don’t think it affects most, and why it has this affect on a few I’m not sure, but I know in my case it was in issue. However, I saw some color problems more than density.

Wayne, when you re-installed the Epson driver, was it to a more recent version? I ask to see whether the problem could have been simply the driver not being in sync with the latest OSX version. If it's not that, it's disturbing, as it raises once again the issue of colour management inconsistency with OSX upgrading that has happened in the past. And if so, one wonders what greater amount of quality control and coordination with application developers and printer manufacturers would improve reliability. The way it is supposed to work is that OSX SDKs go to developers and manufacturers a good while before release so that all may do the needful to render their products fully consistent. Again one wonders to what extent this happens effectively enough.

The answer is obvious. :)

"obvious" to which question - I asked more than one and they lead to different diagnoses!

George, I'm not sure how obvious - sometimes things happen that are unique to some users' systems for reasons that take a lot of diagnostics, and sometimes they are generic. Hard to tell without much more evidence.

When the problem is not generic I can accept it. But when it is generic...

I've seen no changes with Mojave 10.14.2 and the latest Lr with regards to viewing or printing.

The last time something like this happened I found out that a friend sat at my Mac and decided he was going to mess with the brightness of the display.  After that episode I changed the keyboard settings so that F1 and F2 did NOT adjust brightness.  That issue has never come up again.
