putting some text in bold

Hi I would like to change some text to bold. Its part of another plugin that is showing on the cart page what the user has selected as a product. i would like to make it more clear so making the field output bold see here - http://www.tiikoni.com/tis/view/?id=9013f5f

so shows like this at present

Paper Size: A1 (841mm x 594mm) BW-or-Colour: Colour Finishing: Folded

and want it to look like this

Paper Size: A1 (841mm x 594mm) BW-or-Colour: Colour Finishing: Folded

as those fields would change e.g. "Folded" could also be "Rolled" etc

is there a way to do this?

To see page click on one of the products select an option from drop down then click "Add to cart & upload files" you will then see same page as me

Please dont post any brand related information/ screenshots or domain links as i have had issues with google caching this information and linking it to their google searches of my site ... very bad for brand... please use temporary image upload / tiny url / pastebin etc to mask this information.

Thanks
