Frequently Asked Questions
We asked Photoshop guru Mark Galer www.markgaler.com the following question.
A lot of our clients are buying iMacs and are unable to bring the screen to the 120 to 140 cd/m2 we recommend. We normally recommend Charcoal Design SHADES to fix the issue. This article recommends some other software as well.
Do you have a preferred method to get an iMac profiled to the 120 to 140 cd/m2 we recommend?
That’s an interesting topic you raise about the iMac screens. Because these screens are only 8 bits there is a school of thought that they are not really suitable for calibrating down to 120-140 from their native luminance anyway – due to the banding this may cause. The Shades App does warn that this may not be suitable for colour critical work as it can upset monitor profiling and Apple’s latest Mountain Lion operating system will prevent users installing any app that is not downloaded through the Mac App store (Shades is not currently available).
My own thoughts would be to not recommend an iMac screen for ‘soft proofing’ in a ‘side-by-side’ setup (screen and print viewed at the same time). Most users who purchase a daylight viewing cabinet or set up optimum daylight viewing conditions for viewing prints will probably also be using a better quality monitor as well.
If the screen image and the print are viewed separately (one at a time) most users will not have a problem with Luminance values set higher than 140.
Finally X-Rite has provided an upgrade path to permit i1Display2 users to run their instruments with Mac OS LION.
It is available at http://tinyurl.com/7gsxcrs
X-Rite must have been pretty surprised by the reaction of both end-users and resellers who complained about the situation.
X-Rite, probably had no idea that Apple were going to drop Rosetta from Mac OS LION, although you could argue that X-Rite should have upgraded their software to run natively on Intel-based Mac’s as Rosetta was ultimately going to disappear from the Mac at some point.
It seems X-Rite have listened and acted. Any customer who purchased and registered their i1 Display 2 or i1 Display LT from Jan 1st 2011 will be eligible for a free upgrade.
Customers who purchased the i1 Display 2 or i1 Display LT prior to 2011 will be able to get the upgrade for a small fee (to be announced).
