Problem solved. The fault was mine, not surprisingly. For those who may make the same mistake, here's what I lerarned. In i-1 Match when you press the print button to print a profile, the normal Epson print driver window comes up. It is necessary to bring down the menu for Color Matching and check the radio button for Epson Color Controls, NOT the button for Color Sync. That does it. After posting my question here yesterday, I emailed X-Rite support with my problem and also checked their FAQs. That turned up a document titled "Prints look too dark using printer driver with Leopard." X-Rite Support responded today with a link to the same document. I should have done this leg work before I posted my question. Thanks to pherold for his post above suggesting fix.
