Choice of Writing Implements: We recommend a ball-point pen with waterproof ink for best results on any of the papers that we sell. Why buy waterproof paper and write with a standard ink? Medium-width pens generally work best. Fine and extra-fine points can cut into the paper under heavy pressure. Broad-point pens often deposit more ink than the paper can absorb and result in smearing. When writing on a paper that accepts pencil, we recommend hard, broad leads with blunt points. COLD AND HEAT: The paper that we sell that has been tested to perform under the widest temperature range is PuffinPaper. It remains pliable and writable at temperatures from -70°C / -94°F to 180°C / 356°F. The temperature at which your pen or your body can function will limit your work before the paper does. Other papers can have narrower ranges of temperature performance. They can become brittle in very cold weather. They might soften if you attach them to a hot billboard in direct sun. We don't recommend them for use in very hot or very cold situations.

Coronavirus update* Zecom® waterproof paper can be sanitised using alcohol wipes without losing any integrity. We recommend using it for all office or outdoor notices. If you need adhesive Zecom® please look at our Zecom-TAC. Make your own waterproof and hygienic signs.Use in inkjet, laser and copiers. Great pen performance but does not accept pencil. Gel pen inks will smudge. Puncture, tear and abrasion resistant. Not recommended for use in high temperature printers or copiers. Avoid smearing and excess ink: We recommend printing using the "light" or "draft" or "economy" settings of your printer. Printing in "high quality" or "dark" mode usually applies more ink than the paper can absorb. That will cause ink smearing or ink that does not dry. If the ink smears or does not dry in "normal or "standard" mode see if you can print with a "light" or "economy" mode. For best results use the lightest printer setting that produces readable print. Cutting: These papers can be cut with scissors and paper cutters. Their water-resistant qualities are not reduced. Waterproof & weatherproof paper - impervious to moisture, freshwater, saltwater, rain and even treated swimming pools! When printing 5Mil TerraSlate, use the regular paper or the glossy paper setting for the best results.

All four branches of the US Military including the US ARMY, NAVY, Marines, Air Force, and the US Coast Guard Tolerant to fluctuations in temperatures - once printed, can be used in temperatures ranging from -40°c to 120°c Writing Underwater: All of the papers that we sell work well for short-term underwater use. We placed a sheet of each of these papers underwater for one month, writing on them weekly with a waterproof ink pen. They retained their integrity, accepting and retaining the ink. For scuba diving we recommend writing with pencil on a DuraRite Notebook. Why? Pencils work best for underwater writing. Waterproof pen refills have a small amount of gas in the refill to control the flow of ink. If they are taken deep enough that the outside water pressure is higher than the inside gas pressure, water will flow into the refill and dilute the ink. The critical depth is variable - depending upon the amount of ink that has been depleted and the gas pressure in the refill. Always test before use in a critical project. Soluble inks can wash right off. Be sure to test your pen, printer and paper combination before going into the field or starting a project.
