Litho lamination is a two stage way of printing a corrugated box. First a top sheet of paper is printed on an offset (lithographic) press, exactly as a magazine cover would be. Then that printed sheet is laminated onto a corrugated substrate, and only then is the board die cut and folded into a box. The image is never printed onto the fluted board itself.
Why the extra step exists
Corrugated board is not a flat printing surface. Underneath the liner is a wave of paper, and printing directly onto that surface can show the wave through the image, an effect the trade calls washboarding. Fine type, gradients, photographic images and large solid areas are where it shows worst. Printing the image on a flat sheet sidesteps the problem entirely, because the sheet is smooth when the ink goes down and the fluted board is only introduced afterwards.
How it compares to the alternatives
| Method | How the image is applied | Best for |
|---|---|---|
| Litho lamination | Offset printed sheet laminated to corrugated | Retail display corrugated, photographic images, large solids |
| Direct flexo print | Ink printed straight onto the corrugated liner | Shippers, line art, one to three colours, high volume |
| Digital print | Printed straight to the board, no plates | Short runs, versioning, fast turnaround |
| Digital litho label | Digitally printed sheet laminated to board | Short run work that still needs photographic quality |
What it does to the box, not just the print
Laminating a printed sheet to corrugated adds a layer of paper and adhesive across the whole panel. That does two useful things beyond appearance: it stiffens the panel slightly, and it gives you a coatable surface for gloss, matte or soft touch lamination. It also means the outer surface is paper, so scuffing behaves like paper rather than like a printed liner.
When it is worth the extra step
Specify litho lamination when the box is doing retail work: a shelf ready display, a product box a customer sees on a shelf, a subscription box where the unboxing is part of the product. Do not specify it for a plain outer shipper that will be opened once and recycled. A common and sensible structure is litho laminated retail packaging inside a directly printed corrugated shipper, which puts the print quality where a customer sees it and the cost nowhere else.
What we need to quote it
The box style and internal dimensions, the artwork or at least the image type, the board or flute you want under the sheet, and your quantity. Flute choice still matters under a laminated sheet, and E flute is the usual pick for retail work because its shallow profile gives the flattest surface. See our flute guide for the profiles, and corrugated boxes for the formats we run.
Ordering and turnaround
Minimum order is 100 boxes, from about $0.48 per unit at bulk volumes, confirmed on your written quote. The die, the plates, design support, US shipping and a digital proof before anything prints are included. We produce in West Chicago in the US and in Guangzhou in China. Three lanes are quoted per product: rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days in production plus 2 to 5 days for delivery, and laminated work sits toward the longer end of any lane because of the extra process step.
Send your artwork and your box dimensions and we will quote litho laminated against direct print so you can see both. Request a quote to compare them.
