Halftones are a percentage of a solid color. The napkin example below shows an image with a halftone paying homage to the television series Mad Men. Parts of the image are 100% black but certain parts are only a percentage of black. When a color is printed as a percentage (e.g., 20% or 40%, etc.), it will appear dottier. Sometimes this can work to great an effect as in the example below, but it is something to consider if you do not want this look. On certain products there is a minimum and maximum percentage we can print a color (e.g., min of 20% and max of 40%). This will depend on the item so please contact us if this is a concern with the item you are ordering. If you do not want the finished product to have this grainy appearance, the other option would be to print as a separate color and not as a percentage of black, or simply remove the halftone and leave the color of the item.
A gradient is when a color scales from dark to light or light to dark. Gradients can be very subtle or very dramatic. In most cases, we can only print gradients when printing digitally. Below is an example of a gradient.
