A wire watermark is typically tin line art or type, and the mark is lighter than the paper. The wire mark appears more translucent than the surrounding paper when held to the light. It appears darker than the rest of the paper when placed on a flat surface. Wire marks are an excellent choice for designs with fine intricate details.
A shaded watermark allows for larger areas to be utilized. The shaded mark looks more opaque or darker than the surrounding paper when held to the light and lighter than the paper surrounding it when placed on a flat surface. Shaded designs are ideal for artwork with block lettering or solid images.
A combination private watermark is one that includes both wire and shaded elements, giving the mark more depth and flexibility of design.
