Abstract: An original design image is processed to create a modified design image for blending with an image of a product to create a combined image representing the result of printing the design image onto the product. To create a modified design image, both the alpha value and color of pixels in the original design image are modified. The modified alpha value and the modified color of a pixel are determined as a function of the amount of gray in the original color of the pixel. The modified pixel color is calculated by subtracting the level of gray in the original pixel color from each of the three original component color values and increasing any remaining color component values as a function of the modified alpha value of the pixel.
