Please also be aware of TCYB page length policy with a cap of 12 pages plus two additional pages with a charge of $175/page, for a regular paper, provided that you promise to pay the bill after the publication.

    "cap" is used here in the sense of "limit": an upper limit (as on expenditures): ceiling

To cap means to prevent from going higher than or to be unable to go higher than.

Thus, cap as a noun can mean an upper limit. It's often used to mean a "hard" or absolute upper limit. Usually anything "below" a "cap" will "pass through" OK.

When used in this context, to me it is implying they will process only the first 12 pages you submit, should you submit more than 12, without willing or being able to warn you.
