Half-toning is a print technique that breaks up an image into a series of dots with various sizes and spacing to reproduce a full tone range in artwork without using a gradient. Our Econoflex box designer automatically converts your artwork into a single-color half-tone, so you don't have to worry about figuring it out yourself! 100% black elements will print solid black, while any gray or lower opacity elements will be converted into half-tone dots. You'll immediately see the half-tone result in the 3D preview, and you'll have another chance to review and approve your design during proofing. For best results with half-tone printing, please see our Guidelines here. In the up-close photo below, you can see the varying shades of black/gray that make up the image of the dog and bone are created using variably sized and spaced dots of ink (this is half-tone). Solid design elements, like the 100% black text, are printed as solid shapes for a crisp, high-quality print.
