Hi Southern,
To convert from RGB to CMYK (CYK)is never an easy task. Here are some tips to help in the conversion process:
- In Photoshop 5.x and 6.01 you have an option of seeing what your file will look like before converting to CMYK. Go to VIEW> PREVIEW> CMYK. This will show you how your RGB file will look like once converted to CMYK without actually converting it ‘to’ CMYK.
Or, you can make a duplicate, convert the dupe to CMYK and with the RGB version along side it, you can use tools such as (avalible both in Photoshop 5.x and 6.01) Image> Adjust> Curves (tip: can mess around with the channels in the curves palett), Image> Adjust> Levels, Image> Adjust> Hue/Saturation and for precise control you can use the dodge or burn tools. There are other tools in Photoshop you can use for i.e. like adjustment layers etc, but these are some of the tools I use most of the time.
Another thing you can do to get better results from screen to print is calibrate your system. Here is a link at Apples site that gives the name of almost all the companies that make calibration software:
http://www.apple.com/colorsync/
Then go to COLOR PRODUCTS toward the bottom and click on ‘…PRODUCTS that support colorsync’.
Do not worry, these companies also make calibration software for Windows. I like to use MonacoEZcolor as the software is easy to setup and the manual explaines step by step on how to set it up. Again, this is what I use but I am sure any other software is just as good.
Also, here is a link on successful Soft Proofing by Don Hutcheson (even though it is written for those on the Mac, you can get the idea of calibration and it’s benefits): http://www.apple.com/colorsync/stories/hutcheson/
With a good calibrated system, you can do softproofs real well.
If you would like me to go more into detail about CMS (Color Management System), just let me know and I will. Almost all printers have links to ‘how to CMS’ at there sites. Check it out.
Again, hopes this helps.
Dragon.
