When an adhesive or colorant goes through and becomes visible and/or tacky on the reverse surface of the paper or substrate to which it was applied. It is difficult to test for this characteristic because the results are dependent on such variables as thickness of the paper or substrate and the amount adhesive or colorant applied.
Bleeding – A reaction in the stain or dye that causes the colour to wick into subsequent coating applications.
Bleed-through occurs when an underlying color shows through a subsequent layer of paint. It happens most commonly when the model is made of a strong color such as red or yellow and is painted without use of primer. It can also occur when the first layer of paint has not cured sufficiently prior to the application of another coat.
When printing on one side of a sheet of paper shows through to the other side.
A production difficulty where the previous design used on a structure can be seen through the current message. Can occur because of the kind of paper used, a chemical reaction of certain pigments, or because of excessive wetting from heavy rain.
