Penultimate version of Photoshop: Results are stellar: Average dE of 0.85 on the 24 patches. Results from Photoshop 2015.1.2 (penultimate version) The smaller the difference between the two the more accurate are the printed values relative to the reference values.įigure 2. Figure 2 shows the results for the 24 patches printed from the penultimate version of Photoshop, while Figure 3 shows the results for the current version of Photoshop.įor reminders from my papers and printer reviews, the dE derives from the difference between the known reference values of these colours and the values of their corresponding printed patches, measured off the print. So I made the two prints, let them dry overnight, then measured the patches with my i1Pro2 in ilProfiler MeasureChart, respecting the same conditions that apply to the profile. In other words, the only test variable is the Photoshop version.

With both the new and penultimate versions of Photoshop installed, I could then print the LAB version of the Gretag Macbeth ColorChecker I use for evaluating printing accuracy from each of the two versions of Photoshop (Figure 1), using the same printer (Epson P800), the same Driver (Version 9.79 for Mac of two weeks ago), the same paper (Ilford Gold Fibre Silk), the same custom profile that I know from previous tests delivers pretty accurate results on this test and the same settings in both the printer driver and Photoshop (printer color management off, high speed off, 2880 quality, correct Media Type for the paper and the profile, correct “M” specification for the profile given the moderate OBA content of the paper, etc. Hence I began to suspect that this could be the heart of the problem.įortunately, on CC we are able to roll-back to the previous versions of Lightroom and Photoshop, so I installed the penultimate version of Photoshop – the application I needed for printing these targets because the methodology requires Absolute Rendering Intent not offered in Lightroom. I carefully reviewed my workflow for all possible contributory factors and found nothing amiss – except that before making these target prints I had upgraded both Lightroom and Photoshop to the latest versions.
When I printed these patches in my Epson P800 and measured their colour values with my i1Pro2 and i1Profiler, I was obtaining unusually high dE values (average of 2.0 or more for 25 patches on this target, with individual patches going higher) relative to the results I normally obtained in my tests of inkjet papers and printers for my recent reviews on this website. I had developed a template target in Photoshop forming the basis of this research, for which the reference values of the various patches are known, as I constructed them. I became very interested in this subject specifically because I am engaged in some research on the topic of discrepancies of printing accuracy and their relationship to human visual perception. On June 30 th Andrew Rodney opened a thread on this website telling people that the new versions of Lightroom and Photoshop are printing differently from the previous versions, referring to his own experience and that reported by a growing number of people on the Adobe Forum.
Adobe lightroom 5 problems update#
On the same day, the issue was confirmed for both Epson and Canon printers and reference was made to an Adobe Technical Note essentially telling people to update their printer drivers. Evidence of this began to surface on June 26 th in the Adobe Forum with a complaint about wrong colours printing from the current version of Lightroom. This happens periodically, and we are now experiencing one of these episodes at a very fundamental level: Adobe has broken the accuracy of the printing workflow in both the latest versions of Lightroom CC and Photoshop CC for Mac OSX. As consumers of these products we have come to take the current state of progress for granted and we become justifiably irritated when “things fall apart”. When you think of it, this is a remarkable achievement given the large number of components that need to cohere and work properly, and the fact that there is no one company in charge of all these inputs. Over the past 25 years the photographic industry as a whole and Adobe in particular have invested a fortune of time, resources and money to perfecting the digital imaging workflow, to the extent that we can now reproduce image files on inkjet printers with a very high degree of fidelity between the colour values in the image file and the rendition of those values from the printer.
