Narrative:
Understanding of the ACARS clearance was incorrect. ACARS read 'wevic 1 ksino GRNPA1.' filed route said wevic 1.ksino. GRNPA1. What ATC meant was the entire wevic 1 SID to the ksino transition then pick up grnpa at ksino. The ksino transition is way at the bottom of the chart; and easy to miss. The route in the box and clearance was confirmed by both captain and first officer and we thought we understood it; but were wrong. ATC corrected us on the SID and we continued uneventfully. ATC commented that several company crews have done the same thing and asked we bring it to company's attention. Each station ACARS clearance has a slightly different format. A no kidding standard from the FAA would be a great thing to prevent confusion. The important point is that neither pilot thought he was confused. We both thought we understood it fully. After the error was pointed out; we still studied the paperwork for several minutes to see what the error had been. Just my thoughts. Supplemental information from acn 825832: the combination of the first officer just getting on in the middle of the sequence and feeling a little rushed to get ready; then both of us not spending sufficient time reviewing the legs page more thoroughly; caused us both to misinterpret the clearance. Needed to just slow things down and make sure we were completely familiar with the departure.
