I have searched the internet up and down before posting this, but I am still at a complete loss. Any help would be truly/greatly appreciated. I am using a macbook pro 4,1. (If that is significant to know) I have created a flyer in photoshop using RGB mode. But now it has to go to print, and the printer needs it in CMYK. I went to image>mode>cmyk and saved it as a jpeg and tiff format. I also adjust the selective color under the adjustments option However, when I see it previewed on the desktops screen, it has a "gray/washed out tint" to it. When I use leopards preview to view it, it appears the same way, washed out, as well as with safari browser. However, when I view the jpegs and tiff files in Adobe Photoshop or Illustrator, the colors appear to be normal. When I use the mail application to email it to another email address of mine, the colors appear to be normal on the same screen. Is there a problem with the application Preview which causes it to appear this way? Or do I need to start from scratch working in cmyk mode? When I do start a blank document, lets just say a black background, save it to my desktop and view it with the quick preview (pressing the spacebar) or through the preview application, the now black color appears a grayish. This leads me to believe its the preview app, but maybe I am wrong. I have no formal teaching with photoshop, but I have read a lot about cmyk and rgb, and I can not get a definitive answer to this problem. I am just afraid that when I do send it to the printer, and pay for it, that the results will come back with this gray overlay to it. thanks for any and all help.
