(LK: Lightroom Knowledge, not quick and dirty tricks, for learning is neither quick nor dirty.)
I wrote in an earlier post about the printing issues in Lightroom 4. Since then I have run a series of tests and can say with reasonable certainty that the print engine in Lightroom 4 needs some repair. I realize that there is now a print adjustment option, but that should not be an excuse to significantly deviate from Photoshop CS5, CS6, and Lightroom 3. The output from LR 4 also deviates from the screen view on my calibrated and profiled monitor.
Here are the evidences since the last post. Considering the possibility of equipment and software related problems stemming from my system, I copied the file to my wife’s HP computer. That computer has only Lightroom 3 and Photoshop CS5 installed. I printed the same photograph from Lightroom 3 and Photoshop CS5 on that computer, they were identical. Then, on my system, I printed the very same photograph from Photoshop CS5, Lightroom 3, Photoshop CS6 Beta and they were also identical and did not differ much from those I obtained from the HP. Then I printed the same photograph from Lightroom 4 and it was significantly lighter. There is no question in my mind that the culprit is Lightroom 4. There are differences between the print sets from two computers but a small one. However, both prints from CS5 and LR3 on the HP are identical, as are the three prints I produced on my computer. The deviant one is from Lightroom 4, and it is lighter by a good amount than any of the prints from two separate computers.
This is a serious problem for Lightroom users who use this software as their main application for editing and outputting their photographs. I am asking Adobe to take a look at this problem and repair whatever that needs repairing.
