20pt Chipboard Covers

Start with the finished document, not only the inside sheet size. A standard letter size report usually takes a standard letter size cover, but the choice changes if the document includes tabs, index allowance, oversize sheets, or anything that extends beyond the page edge. Buyers often order by loose paper size and then find the finished book looks too tight or leaves dividers exposed. A simple sample build helps avoid that mistake. Gather the inside sheets, any dividers, and the binding style you expect to use, then measure the finished piece as it will actually sit in use. Cover size should support the complete document, not just the stack before assembly. That extra check matters more with rigid boards because there is less room to hide a sizing miss once the book is finished.

The main question is whether the binding method is already settled. Pre punched covers save time when the hole pattern is fixed and you know the document will be finished in the same way every time. Unpunched covers make more sense when you still need flexibility or when different jobs may use different punch patterns. That choice matters because chipboard is less forgiving than ordinary cover stock once the holes are already in place. A wrong pattern can turn a useful cover into dead stock. Buyers also need to think about whether the machine handles rigid boards well enough to punch it cleanly in house. If size is still being decided first, chipboard covers by size can help narrow the choice before you commit to punch details or finishing steps.

It can, but the real issue is whether the punch and finishing setup handle rigid cover stock cleanly and consistently. Many machines can manage board if the cover is punched separately from the inside sheets, but lighter duty equipment may struggle with clean holes or consistent alignment. Buyers should think about the binding style as well, because comb, coil, and wire all depend on different hole patterns and different tolerances at the edge. Trouble often shows up as rough holes, cracking near the binding edge, or poor registration once the book is assembled. A sample punch is a smart step before buying in volume, especially when the machine is older or lightly built. The board thickness alone is not the problem. The fit between the board and the finishing setup is what matters most.

Most buyers use chipboard most often on the back because that adds support where the document needs it most during reading, handling, and stacking. A front chipboard cover can work well when the piece needs a fully rigid look, but many people still prefer a clear or decorative front with a sturdier board on the back. The best setup depends on the purpose of the document and the impression it should leave. A training manual, workbook, or office report may only need the added support of a firm back cover. A presentation book may look more balanced with a matched front and back board. For jobs that need a similar look with a little less stiffness, 18pt chipboard covers are often worth considering before you place a larger order.
