Default Kitty Kat Gotchas or How Snow Leopard may pounce

Quote:
kt: Any other gotchas? (Still sitting here with the Snow Leopard DVD safely in its little box.)
Probably would not affect you but there is a significant problem with SL and color management as implemented (broken) by Apple. One work around has been suggested and apparently does work and when one is trying to print paper targets which would then be used to create a custom paper profile the suggestion is to print via Apple's Preview...

It appears that Apple, much touted for its support of the graphics world, has turned its back on that market much to the dismay (and anger) of all those mac afficionados out there...

Thanks — I heard about that one, too.

Apple has always had a love-hate relationship with its most loyal user base. Never could figure out why. Those glossy displays are another case in point.

The suggestions I've seen are that it's an Epson driver problem. Have you seen different?

Not really but then I'm an Epson girl ('-}}) so I frequent the Epson lists...

Having said that, I'm not sure it's only an Epson problem because as I understand it--particularly from that Luminous Landscape link --is that the problem lies in the Apple API used in CS4 ("The reason you don’t see these issues when printing from Photoshop versions CS2 and CS3 is because they use the older Apple print APIs, which are now deprecated in Leopard and Snow Leopard.").

What I don't know is who wrote the API code--Apple or Adobe?

Also, this appears to affect only some of the Epson printers--from what I've read, I think it's the large format printers starting with the 4000 series and I think the 3800 works ok with CS4 and L/SL but I may not be remembering correctly...

Given that the printing APIs were changed in Leopard, which was released quite a while ago, and that Adobe has been using the new APIs since CS4, I'd be looking at the thing that's changed with Snow Leopard: the print drivers.

it's not necessarily that simple -- there have been further API changes in Snow Leopard -- but I think it's a bit of a long shot to point to it as a sign that Apple "has turned its back" on the graphics world.

What's really happened is that something that involves software from three companies works differently from how it did before -- that sort of thing happens all the time, it seems to me.

Sounds like Epson need to update their drivers.

I have to say that I've never seen the point of colour management. It always just seems to change the colour of things to something you don't want.
I just use CMYK and strip out any of that nonsense. Never had a problem.

I've been running Snow Leopard very happily - many improvements and faster than Leopard.

Perhaps but the way I understand the article is that it's the OS handoff that is the source of the problem ("...the OS appears to be applying a color transformation (via ColorSync) to the profile target image data before handing it off to the printer driver...")--note! this problem rears its head when trying to turn off color management so that paper profiling targets can be printed so that a custom paper profile can be created and if one is using printer maker supplied profiles, I don't believe this is an issue.


>>I have to say that I've never seen the point of colour management. It always just seems to change the colour of things to something you don't want.

Depends on how/what you are printing. I rarely print to Epson papers on my Epson 4000 because I prefer Hawk Mountain Art Papers paper and so I need a custom paper profile to print on this paper successfully. To do that, I need to use color management so that all the parts--OS (WinXP)/video, Photoshop and printer--can "speak the same language"...

As I'm pc based and therefore real-world-mac-clueless, I only know what I read on the ColorSync Users list and lots and lots of the members are quite unhappy at what they see as the direction Apple is taking...

I don't disbelieve you; I just don't see how a simple bug can be held up as proof of a conspiracy when there are much simpler explanations.
