Posted by pbaldwin on | Comments Off on Direct-to-Object Printing Equipment: It’s What We Do!
When I tell people that Engineered Printing Solutions builds printing equipment, I usually see a look cross their face as they picture huge offset printing presses with enormous rolls of paper flying through them, like those scenes out of a movie from the golden era of Hollywood that end with a spinning newspaper boldly trumpeting a sensational headline. When I explain that we make printers that print on everything BUT paper, people usually get a confused look on their face. Then I point out the speedometer dial in their car, the branding and instructions on the front panel of their washing machine, or the logo of their favorite football team on the glass they are drinking out of, and I explain that what we specialize in is building “direct-to-object” printing equipment.
Wait, What Is “Direct-to-Object” Printing?

Direct-to-object printing is just what the term implies: printing branding or other decoration directly on three-dimensional objects—everything from drinkware to disc brake rotors to packaging for Consumer Packaged Goods (CPG). More traditional methods of decorating usually focused on printing labels (or, more recently, heat-shrink sleeves in the case of many consumer packaged goods) which were then applied to the product.
Flat objects such as this cellphone cover present fewer challenges than more 3D shapes.
It should be noted that direct-to-object (DTO) printing is also sometimes referred to as “direct-to-shape” printing. Some people use the term “direct-to-shape” to refer specifically to objects or parts that must be rotated or moved in order to mark all sides of a 3D part, though most people use the terms “direct-to-object” and “direct-to-shape” interchangeably.
Benefits of Direct-to-Object Printing
Direct-to-object printing has several advantages over traditional methods of product-decoration. First and foremost is the elimination of the need to maintain a sufficient inventory of labels (usually printed by a third-party vendor) to prevent production bottlenecks. The addition of labelling machines and label inventories typically requires a greater factory-floor footprint than DTO methods of part-decoration.
By eliminating the dependency on a third-party label supplier, brand owners can rapidly prototype designs, resulting in faster time-to-market for products. Indeed, the rapid changeovers that direct-to-object industrial inkjet printers facilitate not only result in fast prototyping, but they also make extremely short runs economically viable. This opens up a world of possibilities for personalization of products, including versioning and customizing for seasonal and regional variation. Direct-to-object inkjet printers also allow manufacturers to maintain leaner inventories of their products themselves, as they can maintain inventories of semi-finished goods, marking and decorating them “just-in-time” in response to fluctuations in demand along regional or seasonal lines. Leaner inventories also mean less waste of scrap product and unsold inventory.
Finally, direct-to-object industrial inkjet printers such as the ones we build tend to be more environmentally friendly than other methods of product-decoration. Because our direct-to-object printers use
solvent-free UV inks and drop-on-demand technology, only enough ink is jetted to mark the part, resulting in very little wasted ink. UV-LED lamps instantly cure the ink to the part, providing durable decoration free from migration and resistant to scratching, peeling, or flaking. Further, the elimination of printing plates and extensive make-ready at the beginning of print runs also contributes to overall savings.
Challenges of Direct-To-Object Printing
Parts such as this hard hat present a greater challenge, but this helmet was printed on a single pass inkjet printer built by EPS. We have built several hard hat printing solutions over the years.
Direct-to-object printing is not without its challenges, particularly with single pass inkjet printers. Inherently, jetting all the ink necessary in a single pass—hence the name—to create complex designs with subtle gradients and photorealistic imagery on a three-dimensional object moving through space introduces unique challenges. These include, but are not limited to, wind turbulence generated by the movement of the part, the necessity for consistent transport and precise drop placement accuracy.
While the usual solution to this problem is to place the print heads as close to the part as possible (ideally no more than 10mm), most industrial parts have topographical relief in excess of that. At line speeds up to 50 inches per second and higher, ink chemistry and the physical properties of the ink, such as viscosity and shear, must be known and precisely calibrated. For proper adhesion to occur, the surface tension of the substrate must be less than the surface energy of the ink, and to achieve this inline plasma pretreatment is often necessary.
Where a white base layer is applied prior to other colors, UV-LED lamps must instantly “pin” the white ink so that the colors laid down on top do not blend with it. Finally, dedicated software must take into account the precise topography of the part to be printed in order to subtly alter the 2D image to conform to the 3D part and avoid distortion.

America has a throughput problem. How to stick over 600 million doses of COVID-19 vaccine into arms as quickly as possible?
We have written in the past about the logistical challenges of administering the COVID-19 vaccine to the US population—the challenges of manufacturing the vaccines and distributing them. This is a classic throughput problem, so let’s take the same approach to the problem as we do when trying to shave seconds off of a print cycle. (See “Seconds Matter.”) Simply put: find the bottleneck.
Production bottlenecks can have you singing the blues too.
On Friday, February 12, the US Food and Drug Administration (FDA) found and removed one such bottleneck in the supply-chain for the COVID-19 vaccine. In this instance, the bottleneck was quite literally the bottle, or rather, the number of doses per vial. The FDA granted approval for Moderna to package 14 doses of its COVID-19 vaccine into each vial instead of ten. Since Moderna supplies half of all vaccines in the US, this simple ruling increased the national vaccine supply by 20 percent, without requiring any changes at any stage of the supply chain. No new lines were added; no new tooling was required to accommodate larger vials.
The objective in bottleneck-hunting is increased efficiency, as one could easily double throughput by doubling inputs, from raw materials to labor and machinery. But this also doubles cost, and companies like the rest of us live in a world of constraints, whether they be financial or simply factory floor space. Finding and removing the bottleneck should initially result in increased output using the same level of inputs.
This is the goal of our Sales Engineers whenever a customer brings a direct-to-shape printing challenge to us and asks, “How can I do this faster?” Frequently, as we have seen, precious seconds can be found in upstream activities such as part-loading. (See one such solution here.) Alternatively, perhaps it is the pretreatment subroutine. Part-unloading activities may also be the bottleneck.
Have you got a throughput problem? Drop us a line today, and one of our Sales Engineers would be happy to discuss it with you. At Engineered Printing Solutions, we have helped companies in industries as diverse as automotive, medical device and drinkware find and create value and develop new products. Let us do the same for you.
Posted by pbaldwin on | Comments Off on How Do You Vaccinate 320 Million People Quickly? The XRV Rotary Syringe Printer Can Help.
After a terrible year in which so far over 260,000 Americans have succumbed to the novel coronavirus, and with millions more deaths worldwide, it appears as though there is light at the end of the tunnel. No fewer than three different vaccines are either in final stages of testing or are in the initial phases of being rolled out to patients.
It is estimated that “herd immunity” occurs when a minimum of 70 percent of the population is vaccinated, which will require two doses. But just how do you quickly vaccinate 320 million Americans—twice each—in a short period of time? Not only do vaccines take time to culture (you can’t cook a Three-Minute Egg in one minute simply by turning up the heat), but so too do all of the ancillary products take time to manufacture, products such as the syringes with which to administer the vaccine.
Six hundred and forty million doses means 640 million syringes. How do you scale up and manufacture nearly three-quarters of a billion syringes as quickly as possible? In a word, automation. As with so many manufacturing processes, the bottleneck activity in part-marking is usually the ancillary activities adjacent to the actual process of marking the part, with part loading and unloading being the frequent culprits. For this reason, we have designed the XRV Rotary Syringe Printer for high-speed syringe marking.
With the XRV, the operator loads bulk syringes into a waterfall feeder that cascades into a vibratory bowl feeder. As the parts revolve around the bowl feeder, the syringes fall into a track and become aggregated in proper alignment for marking. The track then loads a rotating table, which moves parts past a rotating drum that houses nine pads, each of which has picked up the image from the rotating cliché, in a manner similar to how offset presses transfer ink from one roller to another. The rotating table moves the freshly-printed parts past a Hot Wind device to quickly cure the ink. Once the part has cured, it is automatically offloaded for secondary activities such as filling, assembly, and packaging.
With fully-automated load and unload and continuous ink-loading capabilities, the XRV rotary syringe printer is ideal for long production runs—the kind of runs necessary to produce billions of doses of a vaccine. If you are looking for ways to speed up your throughput or to dramatically scale up production, give us a call. We manufacture product-marking machinery with custom automation for companies in every industry. Let us help you Change The Way YOU PRINT.
Posted by pbaldwin on | Comments Off on EPS Announces BottleJet 2.1 Cylindrical Inkjet Printer
New servo motor replaces step motor for increased repeatability and reliability.
Engineered Printing Solutions is pleased to announce a new version of its celebrated BottleJet Cylindrical Inkjet Printer—the BottleJet 2.1. Highlights include an improved lead screw motion motor, which is now servo-electric instead of a “step” motor for increased repeatability and reliability. Other improvements include an improved bottle fixture, with additional guide rollers that can be installed and removed easily thanks to a quick-release latch. We’ve also added a second mandrel with a shorter stem to accommodate larger bottles.
The UV sensor will prevent accidental curing of print heads.
Perhaps the single-biggest change over the previous model is the addition of a UV light sensor to prevent accidental damage to the print heads. If the sensor detects the presence of UV light, the machine cancels the print job and returns to its home position. In addition, there is a new lamp curtain window, which allows the operator to close off unused sections of the lamp that are not required for the curing process. In previous designs you had to remove the second lamp when not in use and tape over any sections that were not being used in the remaining lamp. A new angle-adjustment knob allows speedy adjustments of the curing lamp, where previously it was necessary to loosen a bolt to make adjustments. This time-saving feature will be much-appreciated by operators. Finally, the curing lamp can now be adjusted to have a negative angle, which means that the BottleJet can now print cylindrical objects with the print heads moving from the top of the part to the bottom without the need for reverse-tooling.
The BottleJet 2.1 has other upgrades as well. A new red laser guide on the head carriage enables the operator to easily set the print origin on the part. An improved method for stirring white inks even when the machine is off reduces startup time. Even the firmware has been upgraded to power the new features of the BottleJet 2.1.

Enhance the safety of your employees while promoting brand awareness. Putting your logo on your company’s hard hats isn’t just good marketing; it could also make your employees safer. And Engineered Printing Solutions currently has a unique opportunity for a turnkey hard hat pad printing system.
The coronavirus pandemic has wreaked havoc on long-term plans for many businesses. Unforeseen shifts in supply and demand have upset traditional industries (who knew that the moribund retail grocery industry would have such a banner year?) and made instant superstars out of startups (hello Zoom). Other companies have rejiggered capital investment plans, some speeding up projects to take advantage of historically cheap money while others are cancelling projects that no longer make sound business sense.
In May of this year, one company that falls into the latter category took delivery of a hard hat pad printing system designed and built by Engineered Printing Solutions. Due to the rapidly-changing business climate in the age of Covid-19, the project for which the system was purchased was cancelled before our customer even had time to uncrate the machine, and EPS agreed to find a buyer for this never-used equipment. This represents an incredible opportunity for someone looking for a turnkey hard hat printing solution, as the system is crated and ready for delivery, with zero lead time, as all of the development of the system such as finding the right pretreatment method and part transport system has already occurred.
At the heart of the machine is a KP08 3 Color Extended Neck pad printer, with three 110mm circular ceramic-ring style sealed ink cups and three pads. Integrated twin plasma pretreatment nozzles ensure perfect adhesion. A heavy-duty five-station linear servo shuttle transports the part for printing, and a servo-controlled rotational fixture rotates the part for printing on all sides. An automatic programmable pad cleaner cleans the pad at operator-specified intervals, or at preprogrammed setpoints, for perfect image quality every time.
With three pads, the machine can be programmed for a variety of print modes:
3 single images at three discreet locations, with up to three colors each
One single color image at one location
One 2-color image at one location and a single-color image at another location
