CCK fields

I read a couple of other similar requests, but none of them got an answer.
How do I enable the translation of fields in specific content types pages created with CCK, such as 'field_[cck-created-content-type]_[cck-field]'? Is it possible?
Example: I created content type: "shop". The name of this content type (label) is "shop", and I hope it can be translated (in italian, "negozio"). I think this feature is optional, not essential.
But the labels of the fields of this content type have titles (example: "informations about the shop") that are displayed in the page, so that they should be translated when presenting the page in a language.
Of course I can easily translate the CONTENT of the fields, but I guess I must add some parameters in the settings.php file to do what I want. Is this correct? Whate are the variables that I need to add?
Because it seems not to work the way I tried...
