A water-resistant prints refers to output that is not substantially altered after exposure to moisture; even if the color appears to darken, it returns to normal when dried. Scratch resistant means the printed image adheres well enough that light abrasive action with dull objects or fingernails does not significantly damage image without unusually vigorous effort. Tear resistant media is not easily ripped without assistance of a sharp object such as a knife or scissors. Fade-resistant posters include UV inhibitors to slow color fading and shifting. Duration depends upon amount of exposure to the sun.
Whatever-resistant differs from whatever-proof in that the latter means even after exposure to respective tests, the original appears undamaged. Though the term is relative, many interpret the word "proof" in this context to mean indestructible, which of course is not possible when describing paper or similarly thin material. Lamination, when appropriate, improves surface durability.
