White grain covers can support foil stamping, offset printing, embossing, and other customization methods when the artwork, equipment, and material are suited to one another. The textured surface affects fine lines and small type, so artwork that looks sharp on a smooth sheet may need heavier strokes or more open spacing on an embossed cover. White stock gives printed colors a neutral base, but the finish can still alter how solid areas appear. Ask for a production sample when the job includes a logo, tight registration, or a large quantity. The sample should use the actual cover, artwork, foil or ink, and finishing settings. This is more reliable than approving the design from a screen image alone.
