Trouble with 100% Red, Green and Blue


Recommended Posts

Hi,

When comparing prints, I am happy with the greyscale and Macbeth colour patches in the example but the 100% Red, Green and Blue are 100% less luminescent/vibrant on my print!

I'm not sure where to go from here - about 6 months ago I had a picture I tried to print that had reds and earthy browns in it and it printed so badly. I spent days or even weeks trying to recalibrate and reprint and non of my attempts worked at getting my picture to what I was seeing on screen. I ended up thinking it was my monitor or my editing which is how I have arrived here. I'm ready to go back to basics with classes and getting help. So is this a calibration issue? Is it normal for everything in the attached picture to appear fine except the 100% colours?  

Thanks.

Oh gee, a touch screen.  They make me nervous.

It's likely that your calibrator is too old to properly calibrate that screen.

But let's not give up right away.

The first thing to do is throw this stupid thing in the bin:

You must only use your own photos to confirm calibration.

Are you following my calibration instructions here?  https://www.damiensymonds.net/calibration.html

Bahahaha - Ay Macarena!  I'm interested in why you don't recommend using a lab's test prints. Isn't that the purpose of them? 

Yes, I'm following your calibration instructions (always). Today I recalibrated as well as doing a full calibration with the same result. In the FullCal today I chose a warm present (6866K), and ECO colour management brightness profile (95).

Yes, I have a few of my own photos printed from the same lab. Unfortunately I no longer have as many as I once did so my comparison is somewhat limited, which I was hoping to use the picture of the lady for. I have 3 photos - one underwater photo on a reef, one portrait and a b&w (though I think it was edited to be b&w by desaturation in LR, so I don't know if you count that as a true b&w photo). Anyway, I'm happy with the brightness of all three prints.

-The reds  in my photo prints don't look as vivid as those on the screen, they are more dull.

The portrait looks slightly warmer in print but the overall the skin tones look close.

The bright red of a coral fish in the underwater photo or the red in clothing in the portrait is much duller in the print.

I would guess that the red of the very bright fish might be brighter than what the lab can print (going by what I read on another post) but I would expect that red in the dress would be within limits. As the skin tones are also close, I am wondering why the red is so off the mark.

- The greens in the prints are brighter than on screen.

This is a little confusing because the hue in the print looks different too - on screen it looks more olive green, but in the print it looks more green apple.

As a side note, the underwater shot has a little yellow in it and it is more dull in print too.

No.  The purpose of that lab print is to test the GAMUT of your screen.  That is a secondary issue.  It only happens after you've finished a successful calibration.  Then you get the lab's soft-proofing profile to check how accurate it is.

This confirms my fears, I think.  A screen's "warm" setting should definitely NOT be this high. So either it's a terrible screen (vaguely possible) or your calibrator is terrible at reading it (most likely).

You need to buy - or at least borrow - a newer calibrator, sorry.

I tried with a different monitor (LG Fratron W2753VC) the presets for temp were:

Normal 4543K

User 4536K

Internet 4634K

Movie 4672K

This monitor will allow me to adjust temp, but the above were taken with the default of 6500K.

Comparing prints, the results look similar to my previous experience - prints show reds that are more dull, greens that a brighter and different hue. The blue on this monitor is brighter and the yellow a closer to the print.

Okay, thanks Damien. I will get onto that asap. Can I assume the devices in your calibration list are up to date, and I can look at something from there?

Also, do you think I should get a different monitor while I'm at it?

Hi Damien,

I hope the rest of your week is going well. I got an i1DisplayPro and have had much better results.

I can see that my screen is a little warmer than my prints. In your troubleshooting instructions you show how to change it but I'm not sure how far I should go if the difference is small. What increment would you suggest?

Some screen shots with the i1;
