Frequently Asked Questions About Binding and Finishing
Why does it matter whether finishing is done in-house or by an outside vendor?
Because every handoff to an outside vendor introduces a new queue, a new schedule, and a new opportunity for delays and errors. When finishing is in-house, your job moves from press to bindery without changing hands. Quality stays under one roof, and if something needs to be addressed, there’s one phone call to make. At Hartley, every finishing process happens in-house in Jacksonville, which means your deadline doesn’t depend on someone else’s production schedule.
What is the difference between saddle stitching and perfect binding?
Saddle stitching uses wire staples through the spine and works well for publications up to roughly 64 pages. It’s fast, cost-effective, and the standard method for magazines, booklets, and catalogs at moderate page counts. Perfect binding uses adhesive to attach a flat spine, producing a book-like finish suited to thicker publications. If your page count is higher, or if the piece needs a spine for shelf storage or a more substantial feel, perfect binding is typically the right choice.
What is PUR glue and why does it matter?
PUR (polyurethane reactive) glue produces a stronger, more flexible bond than standard EVA hot-melt adhesive, which is what most perfect-bound publications use. For publications that get heavy use, ship in variable temperatures, or need to lay flat when open, this is a game-changer. If you’ve had perfect-bound pieces fall apart in the field, the adhesive is often the reason. Hartley’s Muller-Martini Perfect Binder runs PUR glue as standard.
When should I use wire binding instead of perfect binding or saddle stitching?
When the document needs to stay open hands-free. Training manuals, reference guides, workbooks, and presentation materials all benefit from wire binding because the pages lie flat without being held. Saddle stitching and perfect binding both resist lying flat, which makes them a poor fit for documents that need to stay open on a desk or workstation during use.
What finishing options are available for direct mail pieces?
Quite a few. Hartley’s saddle stitchers include inline inkjetting, which means addressing can happen as part of the binding process. Our folders run remoistenable gluing for self-mailers that need a sealed edge to meet postal requirements. We also handle tabbing, polybagging, and shrink wrapping in-house. For most direct mail finishing needs, everything happens under one roof without an additional vendor in the chain.
What is die cutting and when does a project need it?
Die cutting uses a custom-shaped cutting tool to trim a printed piece into a shape other than a standard rectangle. It’s used for presentation folders with custom pocket shapes, packaging with specific structural requirements, direct mail pieces designed to stand out in the mailstream, and any application where the shape of the piece is part of its impact. Hartley makes all die cutting dies in-house. This means we control both the accuracy of the die and the turnaround time, without waiting on an outside tool maker.
What is the difference between foil stamping and embossing?
Foil stamping applies a metallic or pigmented foil to a specific area of the printed piece using heat and pressure, adding a reflective or color accent that ink alone can’t achieve. Embossing raises a design element above the surface of the paper, creating a tactile dimension. The two are often combined on high-end pieces like annual reports, invitations, and premium packaging. Both are available in-house at Hartley on the same equipment, which simplifies production for jobs that require both effects.
Can you handle folding cartons and packaging finishing?
Yes. Hartley runs a Brausse Folder-Gluer with auto bottom gluing specifically suited to folding carton production. For packaging work, the consistency of the bottom fold matters because it affects both the structural integrity of the carton and its appearance at retail. Doing that work in-house gives us direct control over the quality of the finished piece.
How do I know which binding method is right for my project?
You don’t have to figure that out on your own. Page count, end use, budget, and how the piece will be distributed all factor into the decision, and the right answer isn’t always obvious. Bring us your project details and we’ll recommend the binding method that makes the most sense for your specific job.
Do specialty finishes like foil stamping and die cutting affect my production timeline?
They can add time, but because Hartley handles these processes in-house, including making our own dies, the impact is far more predictable than it would be with an outside vendor. We build finishing into the production schedule from the start rather than treating it as an afterthought. This means the timeline you’re given accounts for the full scope of the job.
