When developing a user interface, it’s important to consider what the user needs to see during an interaction. For certain applications, calling attention to an indicator or warning light while keeping others hidden can be crucial. For situations where eliminating distractions, keeping a clean aesthetic, and emphasizing certain switches or indicators is imperative, look no further than dead front printing.
What is dead front printing?
Dead front printing is the process of printing alternate colors behind the main color of a bezel or overlay. This allows indicator lights and switches to be effectively invisible unless actively being backlit. Backlighting can then be applied selectively, illuminating specific icons and indicators. Unused icons stay hidden in the background, calling attention solely to the indicator in use.
Printing methods and substrates for dead front overlays
There are two ways to illuminate a dead front overlay, each of which requires a different printing approach. The first method is to use LEDs directly behind each indicator or icon. This approach simplifies the printing process (since LEDs provide the colors, the printing generally employs a single color behind each button). Alternatively, different translucent colors can be printed selectively behind various indicators. With the use of translucent colors, almost any backlighting method can be used since it’s the ink behind the iconography that gives the indicator its hue.
Diffusers are often applied behind the lights to maintain consistency throughout an overlay. Particularly with LEDs, diffusers can help eliminate hotspots, where one part of the letter or icon appears much brighter than other parts. Once a part is ready, a standard is made, so any future overlays or alterations are readily available and can easily be matched to the standard.
While dead front printing is technically possible with almost any colored bezel or overlay, it’s generally seen on overlays and bezels printed with neutral colors. Typically printed on polycarbonate, polyester, or glass, colors such as white, black, or gray tend to hide unused indicators the most effectively.
Developing dead front overlays with GMN
When developing a new dead front overlay, experimentation is often necessary to get the perfect look. Given the breadth of possible lighting options, ink densities, color palates, and substrates, maintaining a consistent look across an overlay often requires several prototypes to be developed. At GMN, we have a state-of-the-art color lab, a light lab, and a full printing team that works in tandem to match and perfect colors. Within our color lab, spectrophotometers and spectroradiometers are frequently utilized to get specific color values necessary for matching. Our light lab will then work with the printing team to narrow down the exact mixture and density of ink necessary for the specific substrate and required look.
Dead front printing is an excellent option for a wide variety of applications such as automotive dashboards, aerospace indicators, and touch user interfaces.

In our previous blog, we talked about the different kinds of resistive touchscreens and how they compare. While resistive screens offer a high level of versatility, another one of the most widely used touchscreen varieties is the projected capacitive touchscreen. Below, we’ll be discussing the key features and advantages that make projected capacitive technology such a popular touchscreen option.
What are projected capacitive (PCAP) touchscreens?
In contrast to resistive touchscreens, projected capacitive touchscreens don’t require any physical pressure to activate. Rather, they rely on projecting a capacitive field through the display. This field is then disrupted by electrical impulses from the human body when the cover glass is touched. PCAP touchscreens have grown immensely in popularity over the last several years and are primarily used in smartphones, monitors, and any other device that requires both durability and precision.
Advantages of projected capacitive touchscreens:
Originally thought of as expensive and unreliable, the technology for these touchscreens has consistently improved. Over the years, the cost of manufacturing has come down significantly enough to rival that of many resistive options. The specificity to which the input sensitivity can be tuned has also become advanced enough to reject dust, oil, grease, gels, and other agents, while still effectively gauging user input. This makes them ideal for industries where high cleanability and input precision is required.
Since the input is simply a disruption to the capacitive field, PCAP screens allow for multi-touch functionality, such as zooming, rotating, and more. However, due to the reliance on electrical impulses for input, there are limits to what can be used to activate it. The sensitivity can be tuned to register styluses and gloves, but the item used has to be able to successfully disrupt the capacitive field. This may be less ideal than resistive touchscreens for certain applications, where it may be necessary to use other objects to input information.
Due to PCAP touchscreens not relying on separate panels making contact, damage to the cover glass or acrylic generally won’t affect user input, making them durable enough to handle nearly infinite activations. Because of their construction, PCAP touchscreens also display an extremely high-clarity image. Since the layers are bonded together with optically clear adhesive (as opposed to with an air gap between layers as with resistive touchscreens), the displayed image has a high level of light transmission and is very clear. Coupled with rarely losing calibration, they are durable and remain precise throughout their lifespan.
Ultimately, the decision to use either a resistive or projected capacitive touchscreen comes down to the application. Regardless of what type of user interface system you’re looking for, GMN’s experts can help you find the perfect touchscreen for your next product. Find out more about our display integration capabilities or set up a consultation with our experts.
In today’s world, touchscreens are omnipresent and expected by users on almost any interface system. Widely used in a variety of industries, there are many different types of touchscreen constructions available. Once you have decided to use a touchscreen, there are important design considerations to take into account. How should the touchscreen function when interacted with? Does it need to be durable enough for heavy usage and millions of actuations? Should it be incredibly precise and not require any calibration? Whether your biggest concern is cost, durability, or functionality, there are many different options.
The most commonly used touchscreens broadly fall into two categories: resistive and capacitive. In this blog, we will be focusing solely on the different types of resistive screens and their core advantages.
What are resistive touchscreens?
Resistive screens are made up of two conductive and transparent layers: a flexible top panel (typically made out of polyester or PET) and a rigid bottom panel. An adhesive spacer lies between the two layers. When pressure is applied to the top panel, it makes contact with the panel below. This contact interrupts a continuous current flowing between the panels, where a grid of horizontal and vertical lines allows a controller chip to know what was touched and gauge input accordingly. Since the input is calculated through physical pressure causing the two layers to make contact, resistive touchscreens work well for any gloved or stylus usage.
Types of resistive touchscreens:
- 4-wire resistive touchscreen: The least expensive of all of the touchscreen options, 4-wire touchscreens are typically found in games, toys, and other inexpensive touchscreen applications. Since the accuracy is based on the top panel interacting with the bottom panel, any damage to the top panel will cause the accuracy to degrade. This generally makes them less reliable after heavy usage or many actuations. 4-wire touchscreens also have to be calibrated frequently as they get used to ensure that they register the correct input.
- 8-wire resistive touchscreen: Very similar to 4-wire in durability and usage, the only difference with an 8-wire screen is additional wiring. This additional wiring keeps the screen more precisely calibrated and allows it to auto-calibrate, meaning that it requires less maintenance to maintain accuracy than its 4-wire counterpart.
- 5-wire resistive touchscreen: Despite the similar name, 5-wire touchscreens are significantly different from the 4-wire and 8-wire variations. 5-wire screens measure input from the bottom panel only, not in tandem with the top panel. This means that regardless of any damage to the top layer, the usage of the touchscreen and accuracy of input won’t degrade. This makes them more durable and they generally last through many more actuations than other resistive options.
- Resistive multi-touch screen (RMTS): Resistive multi-touch screens (RMTS) are the only type of resistive screens that allow for multiple-touch functionality, such as pinching, zooming, or rotating. Similar to 5-wire screens, the bottom layer is the only layer that measures input, meaning that they’re more durable and well-suited for a rugged environment. EMI mesh can also be applied to the front surface, protecting internal components from outside electrical activity. This, in combination with the durability, makes them favorable for military and industrial applications.
Resistive touchscreens are a great option for a wide variety of applications and industries. To learn more about which touchscreen option is right for your next product, take a look at our website.

Are you in need of a highly durable and high-end looking nameplate? Then look no further than Metalphoto. This incredibly dependable and innovative material is gaining popularity in highly regulated industries such as defense, transportation, industrial and aerospace.
What is Metalphoto?
Metalphoto is a specific type of anodized aluminum used to make nameplates, labels, control panels, serial plates, placards and asset tags. Originally developed for the US Navy in the 1950's and specified by most major OEMs, it is one of the most durable identification materials available today. Our latest video demonstrates the step-by-step process in which Metalphoto components are fabricated.
To begin the Metalphoto process, all that is needed is a digital art file. This art file is transferred via laser onto a pure 1100 alloy aluminum sheet, which can range in thickness between 0.003” to 0.125”. The sheet is then put through a processor that develops the artwork on the photosensitive aluminum. Although Metalphoto images and text are primarily black, additional colors can be screen-printed at this time.
The graphics are exposed and developed like a photograph inside of the anodized aluminum, which causes it to become a part of the nameplate. This unique production method provides the unparalleled durability that Metalphoto is known for. Finally, the parts are placed in a nickel sulfite tank to seal the sliver-based graphics underneath the sapphire-hard anodic layer. All graphics and text on a Metalphoto component are sealed inside of the anodic layer, making it ideal for any identification material where maintaining legibility is crucial. Metalphoto comes in four different finishes: matte, satin, gloss and a #4 brushed finish that resembles stainless steel.
The benefits of Metalphoto
Metalphoto has several advantages over alternatives such as engraved or printed steel. It can sustain an outdoor life of 20+ years, can withstand temperatures in excess of 750°F and is specifically designed to be salt spray and chemical resistant. It is also is resistant to over 7,000 cycles of abrasion.
In addition, the graphics on Metalphoto are significantly higher in resolution than those on etched steel. The method of using a projected image makes any letters, numbers, symbols and pictures extremely legible and appear as crisp and clean as a photograph. Metalphoto is also less expensive than stainless steel in lower quantities, especially for variable data runs. Unlike steel nameplates, it does not require individual engraving, punching or laser marking for variability in images or information. Using the computerized imaging process also makes Metalphoto perfect for serialization, as it does not affect the process or price to customize each Metalphoto plate.
GMN has been a certified converter of Metalphoto for over 40 years and has been provided Metalphoto solutions to several companies including Boeing, Starbucks, Inovus Solar, Lockheed Martin Corporation and more. To see the Metalphoto production process in action, watch our video below.
From luggage bin markers to seat row coupons, the interior of any aircraft comprises of several molded plastic parts. Primarily, there are three ways of printing graphics and texts on molded components namely screen printing, pad printing, and dye sublimation. However, each technique presents its own set of challenges and restrictions. For instance, screen and pad printing are not only time-consuming but also require a high set up cost. As you need different screens (or cliché plates) for even the smallest variation in artwork and color, the market for customization is highly prohibitive. On the other hand, dye sublimation makes it difficult to control color in the artwork and requires special equipment to process plastic. In addition to increased development costs, it doesn’t leave much room for customization either.
To overcome all the above limitations, GMN Aerospace has developed a proprietary technology that allows us to print on slightly contoured or curved surfaces. It also enables us to efficiently customize graphics without increasing tooling costs or processing time. The printed graphics in any aircraft are routinely subjected to harsh cleaning agents. The in-house technology utilizes Original Equipment Manufacturer (OEM) approved inks, thereby preventing the graphics from fading or scratching over time. Supporting the OEM qualification approval process, it also meets the flammability testing and requirements that ensure protection for compartment interiors.
In a nutshell, the proprietary printing process provides our customers with the following benefits –
- Ability to print on slightly contoured surfaces
- Flexibility to customize graphics in a cost-effective manner
- Accommodate low to high volume projects
- Improve durability with abrasion and chemical resistant graphics
GMN Aerospace has always been in the vanguard of embracing new technologies and employing efficient processes. After years of research and development, GMN Aerospace has given flight to this proprietary technology to meet the sophisticated needs of the aerospace industry. By reducing lead time and controlling development costs, the in-house technology is a step ahead in providing more value to our customers.
While the process is currently reserved for decorating plastic molded components within the cabin, GMN Aerospace looks forward to taking this technology to the exterior of the aircraft in the days to come. Envisioning the process to print raised and embossed graphics in the future, the technical experts at GMN see it gaining popularity over the existing techniques such as screen printing and in-mold decoration.

GM Nameplate (GMN) recently added design and development authority to its AS9100D certification. Overall, the AS9100D certification is a Quality Management System (QMS) standard that is specific to meeting the rigorous needs and requirements of the aerospace industry. GMN has been certified under the AS9100 QMS standard since 2007, but the addition of the design and development authority included within our certification as well is a newer development.
So, what does this design and development certification mean to our customers? It means that we are not only in compliance with the latest set of stringent aerospace quality standards, but we are also now certified to take on design ownership of your graphic and functional products.
This certification ensures that we have a robust quality system in place to manage your new project from the quoting process, to design, manufacturing, final testing, inspection, and delivery. Before receiving this design authority, GMN was still qualified to handle all aspects of customer’s projects throughout the entire manufacturing process, however, we were limited to only providing design support and guidance. Customers would come to us with a pre-determined design or concept and we would offer direction on how to manufacture the product. Now, GMN is certified to offer full-scale design and product development services to our customers. Customers can come to us with a rough napkin sketch or basic performance specifications and we can partner with them to design and develop their desired product from scratch. With the high stakes that come with aerospace manufacturing, GMN has the experience, knowledge, and capabilities to aid our customers in designing high-quality products and is confident in our ability to drive and take ownership of that process from conception through final production.
To quickly summarize how this process unfolds, we start with our quoting process, gathering customer input to perform an in-depth design review. We then decide on what processes and materials will be needed, followed by verification and validation of the final design. Once our engineering team has verified that we’ve met all the customer’s requirements, a manufacturing package is assembled and forwarded to the customer service team for entry into our production process for manufacturing. The product is then built, tested, inspected, and delivered!
For any aerospace product, the design phase is undoubtedly the most crucial phase of the manufacturing process because that’s where instrumental specifications for quality, safety, design, and functionality are determined. If the proper quality planning and control systems are not established during this stage, it can have adverse effects on the rest of the manufacturing process. With this new design and development certification, GMN has proven that we have the necessary quality system and design procedures in operation to effectively and repeatedly meet the strict standards expected within the aerospace industry.
If you have an upcoming project that you’d like to explore with GMN, contact us today to meet with our in-house experts.
