To meet the demands of any specialized print job, we offer a premier line of custom finishing tools. Streamline your workflow directly on the press with our Custom PPP (Perf-Print-Plus) Dies for perforating and scoring, or handle complex shapes with a Custom IOC (In-Line Offset Cutting) Die. For projects requiring unparalleled detail, our Custom Chemically Etched Dies deliver intricate results for cutting, embossing, or foil stamping. To ensure perfect results with your in-line system, we also provide the essential IOC Packing Set. Because each of these solutions is manufactured to your unique specifications, they are priced upon request to ensure you get exactly what your job requires.
A Custom Chemically Etched Die is a high-precision tool machined from a solid plate of metal (typically magnesium, copper, or brass) used for die-cutting, embossing, debossing, or foil stamping. Unlike traditional steel rule dies that are constructed from bent steel, the chemical etching process allows for the creation of dies with exceptionally fine lines, intricate details, and complex patterns directly from your custom artwork.
This process makes it possible to reproduce detailed logos, delicate typography, and complex shapes that are impossible to achieve with conventional die-making methods.
The manufacturing process begins with your digital design file. A photo-sensitive coating (a resist) is applied to a metal plate, which is then exposed to UV light through a film negative of your artwork. The plate is then washed in a chemical solution (an acid bath) that etches away the unprotected metal, leaving your design as a raised, durable, and precise image ready for the press.
A single die can be used for multiple applications, including:
Machined from solid metal, these dies are extremely rigid and durable, making them ideal for long and repeatable production runs.
A Custom IOC (In-Line Offset Cutting) Die is an advanced, high-precision cutting tool specifically engineered to be used directly within an offset printing press. Unlike traditional die-cutting, which is a separate, offline process performed after printing, IOC dies allow for printing and die-cutting (or perforating, scoring, and kiss-cutting) to occur in a single, continuous operation.
These dies are typically thin, flexible, chemically-etched steel plates. They are designed to be mounted onto a magnetic cylinder that is integrated as a station in the printing press, usually after the final printing unit.
The primary advantage is speed. By combining printing and finishing into one pass, it dramatically reduces production time, eliminates the need to move materials to a separate machine, and allows for much faster project turnarounds.
Since the die-cutting happens on the same machine as the printing, the alignment (registration) between the printed image and the cut is exceptionally precise and consistent.
The "custom" aspect means each die is chemically etched directly from a client's digital artwork or CAD file. This allows for the creation of extremely intricate and detailed shapes that are perfectly matched to the printed design.
Automating the finishing process in-line significantly reduces the manual labor and setup time associated with a separate die-cutting stage.
Custom IOC dies are ideal for high-volume production of items that require precise cutting and fast turnaround, such as:
An IOC Packing Set is a calibrated collection of durable, precision-thickness sheets used to regulate the cutting pressure and depth within an In-Line Offset Cutting (IOC) system on a printing press. The primary purpose of this packing is to ensure a clean, consistent cut without damaging the flexible die or the press itself.
In an IOC system, a flexible, chemically-etched die is mounted on a magnetic cylinder, which then presses against a hard anvil cylinder to cut the paper or substrate. The distance between the cutting edge of the die and the surface of the anvil cylinder is critical.
A packing set is used to adjust the effective diameter of the anvil cylinder. By adding or removing these thin packing sheets, a press operator can precisely control the cutting pressure to:
A typical packing set consists of multiple sheets made from calibrated paper, polyester, or other composite materials. Each sheet has a precisely known thickness (often measured in thousandths of an inch or microns). The set includes a range of these thicknesses, allowing the operator to combine sheets to build up the exact amount of packing required for a specific job.
Precision Control: Allows for micro-adjustments to achieve the perfect cut depth.
A Custom PPP (Perf-Print-Plus) Die is a specialized on-press finishing tool manufactured to a client's specific requirements for perforating, scoring, or slitting paper directly on an offset printing press.
The standard Perf-Print-Plus system consists of thin, self-adhesive steel rules that are applied to the impression or transfer cylinder of a press. A "custom" PPP die refers to a configuration that goes beyond the standard, off-the-shelf product.
Ordering a custom PPP die means the tool is created to the exact specifications of a particular print job. This can include:
Precision Control: Allows for micro-adjustments to achieve the perfect cut depth.
A custom PPP die helps businesses create professional marketing materials and operational documents that are more interactive, functional, and effective.
Schools can use custom PPP dies to streamline communication, organize events, and enhance fundraising efforts with materials that are easy for students, parents, and staff to use.
For personal projects and events, a custom PPP die allows for a level of polish and interactivity typically seen in commercial products, making your creations more memorable and functional.
