Edge painting

Edge painting is a specialized finishing process where the exposed edges of a printed card are dyed to display a solid color. This technique transforms the raw, white paper edge into a defined visual border, often matching the card’s primary design color or using a contrasting hue for emphasis. It is typically applied to thick stock, such as 300–400 GSM cardstock, where the substantial profile makes the edge visible.

The process involves clamping the stacked cards and applying dye to the sides, which penetrates the paper fibers. An edge painted business card thus presents a three-dimensional appearance, distinguishing it from standard cards with white edges. This finish requires precise alignment to ensure the dye does not bleed onto the front or back surfaces, adding a layer of tactile and visual sophistication to the final product.
