8.5 Inch Super Strips

Choose the width from the actual thickness of the assembled document rather than relying only on a sheet count. Covers, coated inserts, tabs, and heavier paper can increase spine thickness even when the number of sheets appears modest. Place the full document between its intended covers, compress it lightly, and measure the bound edge. Narrow strips suit thinner work, medium strips handle greater thickness, and wide strips are intended for the thickest compatible documents. Leave enough capacity for the sheets to sit squarely without forcing the strip around an oversized spine. When a job falls close to a width limit, make a sample using the final paper and covers. This reduces weak bonds, uneven spines, and unnecessary excess material along the bound edge.

The correct length is determined by the edge that will enter the Fastback machine. An 8.5-inch strip is suitable when the bound edge measures about 8.5 inches, such as a half-letter document bound on its long edge or a letter-size document bound in a horizontal orientation. Do not choose the strip simply because the paper includes an 8.5-inch dimension. First decide which edge will become the spine, then measure that edge after trimming. The broader range of Fastback Super Strips includes other lengths for documents bound along a longer edge. Matching the strip to the spine prevents exposed adhesive, incomplete coverage, and waste caused by trimming a strip that was not intended for the document format.

Yes. Ordinary uncoated copier paper generally behaves differently from glossy, coated, or difficult-to-bind stock. Super Strips are designed for compatible Fastback work using standard paper, but specialty sheets may require a strip made for harder surfaces. Coated stocks can resist adhesive penetration, so a strip intended for difficult paper may be more dependable than a standard option. Paper weight also affects the spine measurement and may move the document into another strip width. Assemble a complete sample with the final stock, printed coatings, inserts, and covers before producing a larger run. Avoid mixing paper types without testing because the bond can vary across the spine. The machine manual and strip packaging should identify the supported material and Fastback system.

Covers must fit the finished document, tolerate the binding process, and align evenly at the spine. Use the final front and back covers when measuring thickness because they contribute to the strip width. A clear front can show the title sheet, while a solid back adds support, but both should have clean square edges where the adhesive bonds. Fastback covers are made for related Fastback workflows and can simplify size matching. Avoid a cover that extends into the binding area unevenly or has a coating that is not suited to the chosen strip. Before a full run, bind one finished sample and inspect the spine, cover alignment, opening action, and bond along both ends.
