Die cutting is a manufacturing process built around a die. A die is simply a metal object with sharp cutting edges. It is customized through cutting, forming, or shearing to produce a desired shape, design, or pattern. In printing and packaging, the die-cut process means cutting out shapes with machinery calibrated to exact measurements. Moreover, those measurements are specified in advance on a dieline. Die-cut printing applies the same process to packaging. Hence, boxes can be cut, printed, and shipped to precise specifications every single time.
That repeatability is exactly why die cutting matters in product packaging design. The machine cuts to the same dimensions on every run. So the outcome stays consistent and professional across an entire production run. Additionally, die cutting is used in both digital and offset printing. It works on manual and digital machines alike. Along with this, it covers process types including blanking, drawing, forming, coining, and broaching.
What Is a Die?
A die is a metal object with sharp areas that cut material. Think of it as a cookie cutter. Whatever shape the metal object is formed into is the shape cut into the material. Furthermore, dies come in several kinds, each with its own strengths. Steel-rule dies are very sharp, so they are protected with plastic or foam for safety. These dies are made to cut thicker packaging materials. They can also cut a stack of thinner packaging in a single pass.
Thinner metal dies are less sharp by comparison. As a result, they cannot cut very thick material. Moreover, thinner dies are lighter and easier to store. They also carry no foam or plastic guarding. Well, that adaptability is part of what makes die cutting so favorable for custom packaging.
Manual and Digital Die Cutting Machines
Manual die cutting machines use a crank that the operator turns to cut the material. The metal die passes through the machine’s rollers. Roller pressure then cuts the shape out of the paper, following the shape of the die. Additionally, some manual machines include motors that help apply this pressure.
Digital die-cutting machines take a more cutting-edge approach. They are generally controlled by software and do not require steel dies. Instead, a blade inside the machine performs the cut. The operator simply selects the shape in software. Moreover, that software can run on a computer, phone, or tablet. It may also come from a specialized cartridge that the machine reads.
Die Cut History: Why Is It Called Die Cutting?
The term “die cutting” traces back to the 1300s. It comes from the Middle English word “de.” That word is believed to derive from the Latin “datum,” meaning “given,” as well as put or placed. Hence, the root meaning of “die” is to place or cast. In the 1300s, dies were used primarily to cast or stamp metal coins.
Mass production of items in matching sizes and shapes took off in the 1800s. So the older term “die” was applied to signify that an item was created by machines. “Cut” refers to creating a custom shape. Together, die cutting means the casting and cutting of shapes. Moreover, the phrase was not in common use until the 1800s.
At that point, die cutting served as a method for producing more precise and accurate shoe sizes. Shoes were made of leather, and the soles had to be cut by hand. Well, that was a tedious process. It often produced errors and ill-fitting shoes. The invention of the die cutting machine finally made standard shoe sizes possible.
The Role of a Dieline in the Custom Die Cut Process
A dieline is the outline of what needs to be cut. It is prepared before any die cut is made on printed material. Dielines are a core part of die cut printing. Moreover, they specify the shape and packaging box size before cutting begins.
Given the range of shapes possible in packaging, the options feel almost limitless. A custom packaging manufacturer can generally turn a concept into a cuttable shape. Do you still need to create one? Read our guide on what a dieline is and how to make one for a packaging and printing project. Furthermore, a dieline must exist before finishing treatments can be applied. These include matte and gloss lamination, embossing and debossing, or UV coating.
Types of Die Cutting Processes
The die cutting process used on a project depends on the specific requirements. It also depends on the intended product. Common methods are outlined below.
Blanking: Blanking takes flat material and slices it by clipping it from the outside edge. As a result, the material looks even flatter.
Drawing: Drawing pulls material through the machine to a specific length. It is typically used for products that are thin, long, or both.
Forming: Forming shapes raw material on a curved surface. Moreover, it is generally used together with drawing. This combination creates cylindrical parts of custom packaging.
Coining: Coining applies pressurized force to create circular holes in the material. Hence, it produces an intricate look in packaging.
Broaching: Broaching uses multiple rows of “teeth” to cut material. It handles stock that a steel die cannot otherwise cut.
Other die cutting types exist in both digital and offset printing. Still, the five above are the ones most often used in packaging.
Die Cutting Services: Flatbed, Rotary, and Digital
Beyond process type, die cutting services also differ by equipment. Flatbed die cutting is also known as steel rule die cutting. It uses a flatbed die cutting press and custom dies to produce distinctive shapes. Moreover, flatbed die cutting suits thicker material and larger packaging components. It is also well matched to short production runs.
Rotary die cutting uses cylinder-shaped dies instead. These convert flexible material into custom boxes or packaging. Additionally, this method suits high-volume production runs. It also serves designs that require exact accuracy.
Digital die cutting uses no dies at all. Instead, it relies on lasers, blades, and tool bits to score, crease, and cut the material. So it is best suited to applications that need fast lead times. Even then, high precision is fully maintained.
Where Die Cutting Fits into Custom Packaging?
Understanding what die cutting is, matters because the choice of process, tooling, and machinery shapes everything about a custom box. It will dictate how precisely that box is formed, how cleanly it will fold, how much it will cost, and how fast it can be produced.
Die cutting uses a custom steel blade, CNC knife, or laser to cut, crease, and score sheet stock into repeatable box shapes. Every layout relies on a dieline—a 2D blueprint defining the cut and score lines before converting, printing, or finishing (like lamination and embossing) begins.
Processes fall into three main categories:
- Steel-Rule Dies: Heavy-duty dies set into wood to cut thick corrugated board and stacked sheets.
- Rotary & Flatbed Cutting: Flatbeds handle intricate, short-run designs; rotary presses drive high-volume, high-speed runs.
- Digital Cutting: Dieless laser or blade systems for fast turnaround and prototyping without upfront tooling costs.

Frequently Asked Questions:
Can I Make My Own Metal Dies?
You can technically make your own metal dies by welding pieces together. Still, doing so is not recommended. Die cutting is best left to printing and packaging specialists. The same is true of the shaping and forming of dies. Moreover, an unusual custom packaging shape calls for expert handling. Having us create the metal die ensures it will work with our specialized machines.
What Are Cutting Pads or Plates?
Cutting plates are also called cutting pads. They create a “die cut sandwich” of the components and materials needed for a packaging design. The sandwich comprises the packaging type and the design. It also includes the other elements that make the end result match the intended design. The process parallels pressing a cookie cutter through dough. You then decorate the shape that comes out. Moreover, cutting pads and plates wear down over time. Hence, they need replacement.
How do tooling fees and order volume determine cost between digital dieless cutting and steel-rule die cutting?
Digital dieless cutting requires zero upfront tooling fees, making it the most cost-effective method for custom box prototypes and short runs despite higher individual unit costs. In contrast, steel-rule die cutting requires a one-time physical tooling charge typically $150 to $500 depending on box dimensions and complexity but drastically reduces unit pricing through high-speed production runs. For custom box buyers, total cost parity generally occurs between 250 and 500 units, where bulk unit savings fully absorb the initial die investment.
