A Kaleidoscope of Crisp Cuts
Finish Substrates with One Device
By Melissa Donovan
Digital finishing is a broad term. Plotters, print-to-cut machines, laser cutting systems, routers, and even semi-automatic devices fall under this category. For many print service providers (PSPs), the best fit is based on commonly used substrates, efficiency, and footprint.
Versatility is a big draw in digital finishing. “Many printers need a wider range of routing tools for maximum application coverage,” admits Steve Urmano, marketing manager, Mimaki USA, Inc. Additional knifes allow for easier maneuverability depending on the material being cut.
Defining a Broad SegmentDepending on the type of application, the definition of digital finishing can vary. Royce Owen, director of marketing, Summa, Inc. explains it in a broad sense, “digital finishing is converting a printed image into a ready-to-sell format.”
Routers, cutters, and even plotters are generally defined based on the type of knife used. Swivel knives are traditional cutting tools that handle less-robust workloads. Tangential knives are used for heavier, thicker media. Rotary knives, also most often used for heavier materials, spin like a pizza cutter. They are programmed to speed up or slow down when not in immediate contact with the material being cut, which allows the knife to execute specific cut lengths. Oscillating knives are handy for thin, light materials such as foamcore or corrugated board, the head of the knife moves up and down at a high rate of speed, which helps prevent fraying.
Laser cutting devices are a bit different, in that the laser, unlike a knife, does not come into contact with the media being cut. “Digital finishing in laser technology refers to processing materials by cutting, engraving, or marking with a non-contact CO2 laser to produce contoured shapes, precision details, and intricate designs in short run or production environments,” says Cherie White, marketing manager, Universal Laser Systems, Inc. (ULS).
Routers, cutters, and laser cutting devices finish a variety of substrates—ranging from wood, aluminum, plastic, foam, paper, cardboard, and more. It depends on the knife blade used or the wattage of the laser. Vinyl cutters or plotters are solely used for vinyl. Some print-to-cut machines also handle paper, textiles, or films—subject to maximum thickness.
Finishing in High Demand“Finishing has evolved into a variety of operations. A PSP may need to cut 50 banners one morning and then deal with producing 100 standees on foamcore in the afternoon. Finishing may include knife-cutting stickers for another client and then producing mock ups of a package. Today, finishing is processing a variety of materials that the print customer can utilize in their printing world,” says David Tebon, sales manager, Zund America, Inc.
With a peak in interest over flatbed printing, routing is a must have feature for many PSPs. According to David J. Cich, VP of sales and marketing, CET Color, as more shops invest in flatbed technology and print directly to rigid substrates, they encounter applications that are unable to be hand trimmed and require non-square finishing. With heavy-duty materials such as wood or even glass, a router with a powerful knife is ideal to achieve the cleanest cut.
Contour cutting, which follows the shape of a graphic, is also in demand. Finishing devices that cut crisply, without fraying or creating jagged edges, around the most curvy graphics push PSPs to up the ante by offering challenging applications to their customers.
“Contour cutting of rigid substrates is particularly popular,” shares Randy Paar, display graphics product manager, Oce North America. “Typical uses are point of purchase (POP) displays, exhibit displays, and booth furniture.”
“This type of application can be found in a wide range of projects, from large wall graphics to table displays. These are often customized for local markets—for example, images of local athletes in which graphics are registered and precisely cut to irregular image outlines,” agrees Don Skenderian, VP market development, EskoArtwork.
Devices with the ability to contour cut precisely for long-length tracking are a necessity, according to Hiro Futsukaichi, marketing director, Mutoh America, Inc.
Automation NationA versatile device—saving time, money, and footprint—is ideal in almost every segment of the graphic arts, and finishing is no exception. In many cases, a digital device means automation, which is arguably one of the biggest time savers, in regards to added versatility and less hands-on time.
“Users always look for a multiple function machine to satisfy customers’ applications. For example, a cutter that cuts vinyl and thicker material like sandblast or thinner material like window film,” shares Sandy Shih, product manager, GCC.
“Versatility is the name of the game in this new economy. Specialization always has a place in the industry, but as more businesses consolidate, the need to diversify is paramount if a company wishes to survive. As the nature of consumer purchase tendencies migrate toward one-stop shopping, PSPs need to capture that business by having as diverse an offering as possible,” explains Dana Curtis, product manager, Roland DGA Corporation.
White agrees, with the current economy, PSPs must do more with less—fewer employees and/or a limited budget. The ability to work with a finishing system that processes various applications allows PSPs to extend their business into new markets or to new customers.
“This ability expands their capabilities, therefore allowing the company to offer other services not previously available to them before,” adds Roy Valentine, sales manager, Techno Inc.
Semi-automatic finishing devices should not be overlooked, they also offer versatility. The Fletcher-Terry Company offers hardware that falls under both semi-automatic and manual categories. “Our cutting equipment utilizes a design philosophy based on interchangeable cutting heads. This gives the user the greatest level of versatility and longevity in their investment,” explains James McNickle, marketing director, Fletcher-Terry.
