Black Composition Strips

Strip width is chosen from the thickness of the assembled document, including covers and inserts. Narrow strips suit thinner documents, medium strips handle greater thickness, and wide strips are intended for the largest supported text blocks. A wider strip may sometimes be used on a thinner document when the machine permits it, but a strip that is too narrow should never be used on a thicker document. The spine must wrap and bond correctly across the full edge. Count and compress the final sheets before selecting the width, since heavy covers, tabs, and coated stock can increase thickness beyond the paper count alone. Following the machine’s strip-width guide helps prevent loose sheets, exposed adhesive, and an uneven spine.

Composition Strips can support hard-cover workflows when the machine, cover system, and strip type are designed to work together. The document block must be prepared to the correct thickness and aligned carefully before it is joined to the cover. Fastback Composition hard covers provide cover options intended for this type of binding workflow. Confirm the supported document size, spine capacity, and any required end sheets or preparation steps before ordering supplies. Hard covers add structure and presentation value, but they also add thickness and reduce tolerance for alignment errors. A test document is useful when a new cover size, paper stock, or strip width is introduced.

Composition Strips are intended for permanent binding, so they are not the best choice when sheets are likely to change after the bind is completed. They work well for finalized manuals, reports, books, and records that should remain intact. If revisions are expected, plan them before binding or use a supply type designed for limited editing on a compatible machine. Do not attempt to reopen a permanent bind using unapproved heat or force, since this can damage sheets, covers, and equipment. Keep the final document sequence controlled before the bind cycle, and inspect sheet order, orientation, and cover alignment first. A simple pre-bind checklist can prevent the need to remake the entire document after one missing or misplaced sheet is discovered.

LX Strips are the better choice when the document is being produced on a Fastback 9 and may need limited editing after the first bind. Composition Strips remain suitable when a permanent result is preferred or when another compatible Fastback model is being used. Black LX Strips are available in narrow and medium widths for the Fastback 9. Confirm both the machine model and document thickness before selecting either strip family. The decision should be made before production begins, since editability, width range, and machine compatibility differ. Keeping strip boxes labeled by machine and supply type helps prevent similar-looking products from being loaded into the wrong workflow.
