Williams & Heintz Map Corporation Print on Demand (POD) nautical charts are produced under the authority of the National Ocean Service, National Oceanic and Atmospheric Administration (NOAA). NOAA is the national hydrographic office for the United States of America. The data from which these POD chart are produced is certified by NOAA for navigation use. POD charts meet the requirements for the mandatory carriage of nautical charts established by the U.S. Coast Guard and published in Titles 33 and 46, Code of Federal Regulations, including the requirements for updating.
Williams & Heintz Map offers the POD Charts on two durable kinds of paper — 24 lb. JCP E-20 High Wet Strength Map Paper, a white paper with a lithographic finish that is made to be used out in the elements. This economical paper is fully functional even when wet. 36 lb. JCP E-50 Chart Paper, genuine 50% cotton nautical chart paper, the same kind of paper as the lithographically printed charts that mariners are accustomed to. While not water resistant, this special surface can be drawn on and erased again and again.
NOAA has authorized Williams & Heintz Map Corporation to sell NOAA’s paper nautical charts that are printed when the customer orders them, or “on demand.” The information on the charts is still maintained by NOAA, and the charts are corrected with Notices to Mariners up to the week of purchase. We print the charts at Super Fine – 1440 x 720 DPI, up to 64 inches wide, on a G7 calibrated wide-format printer. Williams & Heintz uses no toxic solvent inks or dangerous UV processes.
