Briefing the departure procedure the crew missed the non-standard climb gradient to the 16;000 FT crossing restriction at the departure fix. However; the crossing restriction itself was entered in the FMS. As a result; the crew should have notified ATC that it was unable to comply with the climb gradient since the requirement was 500 FPM and Econ Climb only yielded 493 FPM; or use max climb speed; which would have yielded a rate of climb in excess of that which was required. The crew departed and made the restriction; but by maintaining a slower than normal climb speed.Transitioning to the Commercial Chart Company's format seemed to be an issue in this case since the pages in normal mode are illegible; causing the crew to have to zoom in. The Commercial Chart only permits one level of zoom; so the page goes from too small to too big; causing the crew to have to hunt around the page for information. The other issue that must be accommodated with the Commercial Chart Company is that the pertinent information is so cluttered that it gets lost; versus the other Commercial Charts which presented only that information for departure from the particular operational runway. These are factors that the crew will have to deal with and adjust to over time with the use of Commercial Chart Company's EFB.
First Officer chronicles the difficulty deciphering EFB chart information and text in both normal and zoom mode.
