What is the difference between black letters and black & white letters?
Black letters are intended for bumper stickers and adhesive decals for light colored cars. Black letters alone will not show up on a vehicle window. They disappear into the dark interior and are difficult to read. Therefore, we outline the black letters with white (static cling only). Black & white letters work very effectively when ordered with larger size letters. Bumper sticker vinyl is white and we print letters in black, red or blue. The red and blue letters are outlined with black. If you want to put adhesive letters on the body of your vehicle, make sure the letter color contrasts with the paint color. Please email us if you want another color for this purpose (adhesive only).
