The DCA does a good enough job - certainly as far as offset printers are concerned. On bigger jobs we always go down to see the first sheets off to make adjustments. It shouldn't happen, but unfortunately there are a few pairs of interfering eyeballs between you and the printed result. You can't be me, I'm taken
Of course, I have a real Broadcast-spec monitor for video editing but I don't even try to get the monitor to match it (I set my monitor for printing/Internet.) But even that doesn't get used much. If the footage was well-shot, there isn't much need to fix it in post. I work with one cameraman who would probably throw a fit if I messed with his color anyway.
Apple set the monitor at the factory so that pictures from a digital camera will look good--that use is the most demanding requirement of the iMac market. I don't know if they have an Apple store in Finland, but the one near here had the iMacs lined up with rotating full-screen photos selected by the VERY fussy Apple graphics department.
BTW, did you see that Apple announced the new iMacs TODAY. You may be in a position to bargain for an upgrade / price drop--just tell them you want to return the one you just got and see how they respond.
When I got mine, Apple had just released Leopard and like the trendy I am, I immediately upgraded. THAT was a mistake. I had software I could not get running right for three months. But some application programs had updates, Leopard itself has had two, and importantly, there was a recent firmware update so everything is now running full speed. I upgraded the memory to full capacity (4 gigs) before I ever plugged it in the first time.
My iMac is, by FAR the best computer I have ever had the pleasure to run. It is beautiful, quiet, and blazingly fast doing difficult things. I hope it lasts a LONG time. "Remember the I35W bridge--who needs terrorists when there are Republicans"
For video editing I use an ancient Sony pro monitor which I also take sometimes to the studio - I know the feel of the picture. It's like having a favourite vocal mike that you are used to (U87 - though there's an AKG I like with my own voice. I do a lot of voiceovers and I have persuaded some clients to let me record at home. This makes me feel better about not driving into town. You can't be me, I'm taken
