New Dimensions in Digital Printing



Screen printers know the drill: Short runs are rarely profitable, given the amount of time and materials involved in setting up even the simplest job. And forget about one-offs and prototypes.

Screen printers know the drill: Short runs are rarely profitable, given the amount of time and materials involved in setting up even the simplest job. And forget about one-offs and prototypes. But just as wide-format inkjet printers have enabled screen shops to take on low-volume flat-graphics work economically and efficiently, the technology—albeit in a smaller size format—is now making it possible for them to diversify their product offerings, introduce an expanded range of services to their customers, lure in new business, and keep their screen presses focused on the profitable, high-quantity work.

Flatbed inkjet printers that are designed to print three-dimensional items offer an alternative to pad printing, which historically has been the imaging method of choice in many promotional-products applications. The machines can accommodate very thick products that can’t always be handled on other inkjet devices. Via standard or custom parts fixtures, they facilitate direct printing onto products ranging from smart-phone covers to golf balls. These machines typically use UV-curable (often UV-LED) inks and most offer high-speed output in at least four colors.
White and clear inks are becoming commonplace in digital printing, and this emerging category of three-dimensional printers is no exception. Many of these machines incorporate white and/or clear, allowing a greater range of materials to be decorated (including darkly colored and transparent substrates) and enabling effects such as highlights and blockouts to add “pop” to colors. Primers are making inroads as well, opening the door to typically challenging media, such as metal. Read on to find out about some of the systems that are on the market. (A number of vendors also offer higher-speed inkjet systems designed for in-line manufacturing, but in this article we’ll concentrate on machines that would typically appeal to commercial shops.)

Direct Color Systems

The Direct Jet 1024UVHS, the latest UV-LED printer from Direct Color Systems, incorporates several recent upgrades including greater flexibility when printing white and/or clear and print speeds up to 50% faster than earlier models in the line. The machine features eight print heads (CMYK plus two channels each of white and clear), allowing bi-directional printing of both white and clear through a feature the company calls inline printing. The 10 x 24-in. printer offers four production modes ranging from 1440 x 720 to 5760 x 1440 dpi (optimized resolution) and can print items up to 6 in. thick.

Also new to the 1024UVHS is the ability to achieve multilayered effects through the TEXTUR3D print mode. According to the company, users can produce ADA-compliant and Braille signage using the new feature.


The printer uses DCS Multisolve LED UV IR2 inks compatible with a variety of substrates including plastics, glass, wood, ceramics, and metal. Inks are available in 200- and 500-ml bottles for the refillable cartridges. The firm’s Advanced RIP 9 software drives the 1024UVHS and is compatible with popular design programs such as Adobe Photoshop, Adobe Illustrator, and CorelDRAW.

Other models available from Direct Color Systems include the 10 x 14-in. 1014UV, also a UV-LED machine, and a line of four solvent printers ranging in size from 13 x 9 to 13 x 24 in.

Gandy Digital

Billed as a “digital pad printer,” the Viper UV-LED printer has a 24 x 24-in. print area with interchangeable, custom-made jigs to accommodate a variety of materials and applications. The Viper can print products up to 12 in. high and uses Ricoh Gen 4 print heads that deliver 6-pl droplets. Five color configurations are offered: CMYK, CMYK+clear, CMYK+W+clear, CMYK+2xW, and CMYKcm.

A 2- or 3-droplet/pixel mode is available to produce higher ink densities when required for specific applications. Gandy says users can also choose to print four-color designs with two inline rows of white at the same time with no loss of production speed.

Automatic ink-level monitoring is displayed in real time on the specially designed GUI that is fully controlled from an Apple iPad (an industry first, according to the company). Laser-controlled head-height monitoring helps users eliminate the risk of head strikes, nozzle damage, and down time. The Viper also features an anti-static system designed to improve print resolution and clarity, and the LED curing technology eliminates heat-buildup problems on heat-sensitive materials.


Graphics One

Graphics One’s GO F-24 UV-LED flatbed inkjet printer can print objects as thick as 10 in. with a maximum print area of 18 x 24 in. According to the company, the six-color machine (CMYK+W+clear) can print at speeds over 100 sq ft/hr in CMYK mode at resolutions up to 1440 dpi. The system’s One Pass technology allows the user to print a white underbase with process colors in a single pass. Inks are available in 250-ml, 500-ml, and 1-l bottles.

The Go F-24 features a White Ink Ready function, combining an ink-circulation system and pressurized pumps to reduce print-head clogging when printing white. The printer also features InterWave Dot Technology, which is designed to reduce banding. The Laser Printhead Protection function uses light sensors to detect print-path obstructions, thereby reducing print-head strikes.

Promotional products made of acrylic, plastic, ceramic, wood, and other substrates are compatible with the printer. Graphic One’s F-24 RIP software is included.

Inkcups Now

The X2 UV-LED inkjet printer from Inkcups Now is a flatbed version of the firm’s larger XJet model, a unit designed for higher-volume industrial applications. Like the earlier model, the X2 can reportedly print a 20 x 24-in. area in 90 seconds. It accommodates parts up to 3 in. tall and offers imaging resolutions up to 1200 dpi.


The X2 comes with a six-color (CMYK+2xW) inkset. Dual UV-LED lamps and two staggered white print heads allow for uni- or bi-directional white printing. The machine incorporates VDS (Variable Droplet Size) technology, delivering three dot sizes (7, 14, and 21 pl) to print sharp images with smooth gradients. X Series UV inks are packaged in 1-l bulk-ink containers and the company says ink costs average $0.0015/sq in.

The X2 also allows printing onto metal substrates through the use of DigiBond primer, available separately. Users are advised to wipe the primer onto the metal parts and then flash cure it prior to printing.

Standard features include automatic negative-pressure ink maintenance and white-ink maintenance systems, as well as programmable platform-height adjustment for three-dimensional parts. Standard and custom parts fixtures are available through Inkcups Now. The system occupies a footprint of 66 x 61 x 54 in. and weighs in at 1300 lb.
