Unfortunately, the 'best' way to solve this problem is use a MAC. Monitors will always differ on the windows platform, some will be darker then others and 'will' print out slightly lighter or darker then what you see on screen. There are several programs out there that try to help with this problem, adobe gamma, 3deep, etc..

have you set up Adobe Gamma? try that first. if you need more help email me.

also, are you printing this or just veiwing on a screen? try these settings by CTL+SHIFT+K....this will give you a dialog box for your Photoshop color settings (changes will only affect PHOTOSHOP)

i use US Preepress Default when at work (print shop) but when doing things digitally, use the Adobe PHOTOSHOP 4 default.

Images that you view on screen will shift in color when changing settings, but if you sample a pixel, you will see that the color values do not. you can get a more accurate setting of onscreen images (web graphics, digital paintings, ect.) by using the PS4 setting I mentioned above.

....but remember that you must have Adobe Gamma set first, otherwise you will have a very hard time tuning everything in.

Hey Odin - I think your problem lies in PS6's internal color setup. It's right under the 'prefs' menu. You probably have 'monitor compensation' turned on and a wrong profile selected.
I usually turn all that stuff off, since, in order for it to work right, it takes a lot of effort to set up.
Additionally, the monitor compensation is basically a color-correction that's being done before the image is sent to the monitor.
Problem with that:

Photoshop is working in 8-bit space, meaning you get 256 values in each channel (RGB) - even though that makes over 16 Million colors when combined, it's very is to get banding (noticable color steps) - especially when working with similar values.

So, when the compensation is turned on, you get additional banding from that internal color correction - therefore it's hard to spot and correct the real banding.

Turn it off!!!

Hope that helped

You should try to work in CMYK instead of RVB and verify the quantity of black that you have in your colors.
As example, one the publishers I work with warned me that the black ink must be composed of : 50 to 60 % of Cyan, 50 to 60 % of Magenta, 50 to 60 % of Yellow and 100 % of Black.
When you open Photoshop go to Edit Menu and then Colors. You'll find a "Load" button that allows you to choose a Standard Profile.
Adobe Gamma Loader is installed by default with Photoshop. You will find the soft in your Programm Files directory.

For my personnal setting, I sent my stuff to my publisher who printed a professionnal plate. It helped to calibrate my screen.

What you could do is to buy a magazine (artistic specialized is better to be understood) with photos and ask the publisher if he could send you by email one one the pics in its original resolution and size, without any compression.
You load the pic in Photoshop and, then launch the Adobe Gamma loader with the pic in background. Adjust the settings, comparing the magazine and your screen.

A bit off topic. but...

Do not include either Cyan, Magenta, or Yellow as a component of your blacks.. it will yield far from black results. If you do so, then your blacks wont appear as black as they could be and will take on a browny or green tinge (thats why 3 colour bubblejets produce dodgy looking blacks). When working in CMYK it is important that when you want pure black that it is actually pure 100% K (black) without any other colour in it. You can do this within Photoshop's colour picking window.

Besides all that having CMY in your K areas will just confuse someone who is looking at plates, and trying to set trapping etc..

That what I thought before the publisher asked me to do so...
