Mr. Tobie,

Thank you very much for your advice.

Yesterday, I purchased a desktop 5000k lamp. Hopefully this lamp should provide me with a good light to review my soft proofing. 

I'm not sure what do you mean to calibrate my "display to a defined brightness, not to native brightness"?  Also, shall I have the my 5000k lamp on when I calibrate my monitor and when I read the 225 patch High Quality Target with the spectro?

Thanks,
 
Regards from Sacramento,

Jorge

>>That said, I need to ask you a question, since I softproof and and printed the test image. In two different type of papers the test image came out somewhat dark. Should the print look alike the softproof test image I see in the screen?

The match between an image in a universal workingspace (say AdobeRGB) on screen, and in print will have a certain relationship to one another, but will seldom be 'a match' since there are media and ink specific factors in the print, as well as there being an unknown level of light on the print. But assuming a good lightsource, and a reasonable degree of light (say a desktop 5000k proofing lamp), then the match should be quite good for glossy media on a good inkjet printer. 

Using soft proofing should automatically increase that match, especially on matte media. But there are still outside factors. A dim proofing light will make your print look dimmer, and the shadows more clogged, while a too-bright monitor will make your prints seem dark, by making your on-screen image too bright. So make sure you are calibrating the display to a defined brightness, not to native brightness, for proofing uses, and that you are using an appropriate proofing light, in addition to using softproof mode.
