Premiere 400 Strathmore Series is a bristol paper preprinted with a non-photo blue border that is the trademark of all Blue Line Pro boards. This allows the artist to draw comics the actual size that professionals do. Professionals draw their illustrations larger then they appear in the finished product. This helps minimize mistakes. The main advantage of Strathmore is its 100% acid free feature. This prevents the signs of aging such as yellowing. Premiere 400 Series Comic Book Boards have an extensive history as the leading paper used by the professional community. The smooth surface offers the artist a chance for detailed ink work and is suited for pencil and marker. The 2-ply thickness gives the paper extra durability.
