An export crate is a printed product that is also a shipping document. The marks on its face tell a handler where it goes, what is inside and how to lift it, and the crate is then dragged, stacked and stored in conditions that test every one of those marks.

This guide covers what governs a UV printing job on industrial crates and export packaging: why the crate is both packaging and label, which materials are used, what export handling does, how shipping marks are laid out, what weather does, how a stencil-style graphic is planned, what to test, and how a crate programme is controlled.

Why is a crate a marking and durability problem?

Because the crate is both packaging and label.

Its face carries the shipping marks, the handling symbols and the brand, and it is dragged, stacked and stored outdoors.

The published durability guidance for this range asks for the exposure to be described before the test is chosen, and a crate is an outdoor, mechanical and handling exposure at once. Rain, fork tines and straps all reach the same surface that carries the consignee name.

The commercial consequence is that a crate is judged by its readability. A faded handling symbol can cause a dropped crate, and a faded case number can delay a customs check. The print is not decoration; it is part of the logistics.

That changes the design brief. A crate mark is not a logo exercise; it is a set of instructions, and the hierarchy should put the destination and the handling symbols above the brand. The brand can be large, but it cannot push the marks into the corners.

Which crate materials are used?

Plywood, OSB, solid timber and composite board.

Each has a different face, porosity and coating, so the published material rule applies crate by crate rather than to export packaging as a category.

The published approach is consistent: record the material, the supplier and the batch, control the surface, and test a representative part. On a crate the face is often rough, which means the print is designed for a rough surface rather than against it.

Surface preparation is minimal by design. A crate is not sanded to a furniture finish, so the print has to work on the mill finish, and the sample is approved on that surface rather than on a planed offcut.

That also decides the type weight. A light face on a rough board fills in, so the mark is set in a heavier weight and checked at the real distance.

What does export handling do to the print?

It drags, stacks and abrades the crate.

A forklift, a container floor and a strap all contact the face, so the edge of the print and the corners fail first, and the marks are the first thing to become unreadable.

Three failure points matter. The corner, where the crate is dragged. The band or strap, where the print is compressed. And the face, where another crate is stacked against it. Each points to a different part of the process: the edge protection, the layout, or the varnish.

Corner protectors solve the first of those directly. A plastic or cardboard corner takes the wear instead of the print, and it is cheaper to replace than to reprint a crate face.

The published handling guidance treats the finished surface as the thing to protect. On a crate that means keeping the critical marks away from the corners and the strap lines, and using the stencil layout to place them where they survive.

How should shipping marks be laid out?

To the shipping standard and the crate drawing.

Consignee, destination, case number, weight and handling symbols have fixed positions, so the print reproduces an approved layout.

The published approach for regulatory markings is to keep the requirement with the product owner. On a crate the marking requirement comes from the shipping standard and the customer's instructions, so the printer reproduces an approved layout rather than inventing one.

The practical consequence is that the artwork is approved against the crate drawing. A mark that is correct in content but placed on a panel that will be hidden by a stack is a defect.

The customer usually supplies the mark content, so the print shop should confirm only the placement, the size and the contrast. Content errors belong to the consignor, and layout errors belong to the printer, which is a useful boundary to state in the order.

Position matters as much as content. The same case number is readable on the long face and invisible on the end that faces the container wall, so the layout has to say which face carries which mark.

What weather does a crate meet?

Rain, humidity and sunlight on the loading dock.

A crate is often stored outdoors or in a container, so moisture and ultraviolet light reach the print before the goods do.

Three exposures matter. Water, because a wet face can lift a film or swell the wood under it. Humidity, because a container can hold damp air for weeks. And sunlight, because a crate can sit on a dock in full sun.

The published material guidance asks for the exposure to be part of the approval. On a crate that means testing the print on a wet and dried face, not only on a dry sample.

How should a stencil-style graphic be planned?

For the rough face and the viewing distance.

A crate mark is read from a few metres, often in poor light, so bold shapes and strong contrast matter more than fine detail.

Three design rules follow. Use a type weight that survives the grain. Keep the mark clear of the strap and the corner. And allow for the fact that a stencil letter can fill in on a porous face, which is why the sample is checked at the real distance.

The published artwork guidance asks for the printable face and no-print zones to be defined before the file is approved. On a crate the no-print zones are the corners, the strap lines and the forklift pockets.

What should be tested before dispatch?

Adhesion, abrasion and the weather the crate will meet.

A crate is stored, loaded and shipped, so the tape method for adhesion, an abrasion check and the real exposure belong in the approval.

Two published methods cover the technical side. Adhesion is assessed with the cross-cut tape test under ASTM D3359 and wear under ASTM D4060. Where the crate will be stored outdoors, humidity exposure under ASTM D2247 is the relevant check.

The handling test is site-specific. Drag the crate, stack it, strap it and inspect the marks at the corner and the strap line. That sequence is closer to the shipping experience than any bench test.

Then leave the sample outside for a week. A crate that has been rained on and dried tells more about the print than a dry rub, because moisture is what lifts an edge that mechanical wear alone would leave alone.

How should a crate programme be controlled?

With a case, mark and panel matrix.

A programme combines many crates and destinations, so each mark has to connect to the right case and the right panel, and the set is only correct when every one does.

The published campaign guidance asks for a component identifier, a location code, a revision and a release status in the file name and job ticket. On a crate programme the location code is the case number and the destination, and it is what prevents a correct mark from reaching the wrong crate.

Two records make that work. The mark schedule, which lists every case and its content, and the approved sample for the board. The published approach is to keep the sample with the record so a later shipment is matched to the first.

Chemical and material obligations for the inks and boards follow the applicable regulations (REACH), occupational guidance for the workshop is published by the relevant authority (HSE printing), and process practice is published by the industry bodies in the field (PRINTING United Alliance). The packaging workflow is covered in the guide to short-run packaging, and the acceptance discipline in the article on inspection and acceptance records.

What the decision comes down to

A crate is a shipping document printed on a rough board. Identify the face, keep the marks away from the corners and straps, design for the reading distance, test water and abrasion, and keep the mark schedule with the approved sample.

The published packaging and platform guidance for this range sits with the cardboard and corrugated collection and the AJ3220EX page, the packaging workflow is set out in the guide to short-run packaging, and the acceptance discipline in the article on inspection and acceptance records.
