  • 3. What is the meaning of Dead Fronting of Graphic Overlay Panel?

    Dead Front Printing is a printing method of Graphic Overlay Panel. The indicator light, logo and text are usually close to the background color and hidden when they are not illuminated by the light source. This method is conducive to the effective invisibility of the indicator light, logo and text. In order to let you know more about Dead Front

    What does the percentage of Dead Front Printing represent: In order to clarify this problem, Niceone-Keypad made a picture, hoping to help users and users

    A comprehensive introduction to Graphic Overlay Panel icon

    The printing method of Dead Front Printing:

    There are usually two ways to illuminate Dead Front Printing, and there are different printing methods for different illuminating methods. The first is Dead Front Printing’s icons, logos, text or places that need to be lit with different colors of LEDs to light up. Since the LEDs provide different colors of light, the first color is generally transparent and close to the background color. Color, the second and third channels will avoid icons, logos, text or places that need to be lit. LEDs provide different colors of light transmission.

    The second method is to selectively print different translucent colors behind various indicators. By using semi-transparent colors, almost any backlight method can be used, because the ink behind the image provides the hue for the indicator. Just use a white light source to illuminate the hidden colors of different colors. But this kind of printing method is more complicated than the first one, and the unit price will be more expensive.

  • 4. What are the Textures and Finishes of Graphic Overlay Panel?

    There are generally 4 finish options that come with the material of Graphic Overlay Panel: Gloss, Matte, fine, and Semi-Gloss.

    • Gloss in Finish:

    This kind of material has very high gloss, the material with the best transmittance and transparency, or the material can reflect more light like a mirror, has abrasion resistance and solvent resistance, the most common material is single-sided hardened transparent Polycarbonate And EBG materials in Polyester. If there are digital tubes or content that needs to be displayed behind the Graphic Overlay Panel, this type of material is a more prominent choice. However, glossy finishes have strong glare. Generally, it is necessary to print frosted ink except for windows to reduce glare hazards.

    • Matte or Fine in Finish:

    This kind of material has low gloss, and the matte surface does not provide any gloss. The matte surface with its own anti-glare effect is often used in areas with less dust and less mold. The main reason is that the Graphic Overlay Panel with matte surface is easy to absorb foreign matter and dust, and the color is easier to change over time. In order to solve this problem, Niceone-Keypad printed ink on the back of such products to avoid such problems. But this is also a problem Matte cannot avoid. But its anti-glare and soft image ability is excellent, so it still has a place in the market.

    • Semi-Gloss in Finish:

    Also called Satin finish, it is most commonly used in Graphic Overlay Panel. Since the beginning of 2015, we have recommended customers to use Semi-Gloss material as the Graphic Overlay Panel. Because Semi-Gloss Graphic Overlay has the advantages of both-anti-glare, and the matte surface is thinner and will not be too easy to cause the material over time Loss of activity, but the price is relatively expensive. Materials such as EBA.

    Advantages Disadvantages
    Gloss The best light transmittance

    Easy to clean

    Relatively long lifespan

    High glare

    Relatively high material prices

    Matte or Fine: No glare problem

    The silk-screened image is softer

    The price is relatively affordable

    The durability is not high

    Weakened color display

    Semi-Gloss Has the advantages of both The price is very high

    What does the Textures of Graphic Overlay Panel represent:

    Texture has the following materials in most cases. As Graphic Overlay Panel manufacture, most of the time we will print different colors on the back of these materials to complete the product design. However, the Graphic Overlay Panel effects brought by different Textures materials are not the same, and their representative materials are also different.

    What does the Textures of Graphic Overlay Panel represent


    The best light transmittance, no texture, glare. Common materials are EBG and high permeability Polycarbonate materials. This material is used in electronic equipment with horoscope lights, displays and other products, because the content of the window is displayed. At the same time, this type of material is generally scratch-resistant and comes with the characteristics of chemical resistance. Cleaning is also relatively convenient and almost non-abrasive. The only drawback is that the material is a glare type material. However, the problem of this type of product can be solved by printing matte ink on the front side except for the buttons and windows. Common thicknesses are: 0.13 0.18 0.25mm

    There is also a new type of Antiglare material-Kotutai’s EBA. Anti-glare and easy to clean.


    The light transmittance is between smooth and fine, and it also has the function of wear resistance. It is easy to clean and has no glare problems. Common materials are EBA or transparent polycarbonate. If there is a large area display under the panel, you can consider EBA. Because the use of Smooth material in a large area of the display window will cause glare problems, which will cause operational errors. Disadvantages: The ink adhesion is poor and the cost is relatively high. Common thicknesses are: 0.13 0.18 0.25mm.


    Common materials are translucent Polycarbonate and Autotype’s F series. The fine texture provides a certain degree of abrasion resistance and LED light diffusion, and they are still easy to clean. Because fine-textured pebbles are smaller and provide less protection than textures with larger pebbles, polycarbonate with fine texture has a shorter lifespan than polycarbonate with larger texture. When used repeatedly, they are more prone to wear and smooth. If the product needs a window to be printed, then a special window ink needs to be used for printing on the surface. The product has no glare problem. The market used is larger.

    Texture and Finish can be said to be the same thing, but in order to let users understand it more clearly, Niceone-Keypad hopes that this copy will give you a more detailed explanation. The following are its main advantages

    Time is money. Niceone-Keypad saves customers’ time. When Niceone-Keypad obtains detailed information, the fastest time for drawing out is within 12 hours. The usual time is 3 days. The sample is usually completed within 10-20 days after the customer confirms the drawing. So what information do we need to give customers drawings and samples as quickly as possible?

    A comprehensive introduction to Graphic Overlay Panel-8 A comprehensive introduction to Graphic Overlay Panel-9 A comprehensive introduction to Graphic Overlay Panel-10

    In terms of drawings: First of all, Niceone-Keypad needs to know the purpose of the product, the specific color number, and editable documents, etc.

    • The purpose of the product includes:use and medical, industrial, military, marine, fitness and agricultural equipment, etc. The choice of materials is different. If you can inform in advance, then there will be a preliminary plan for the choice of materials. The medical industry pays attention to the stability and durability of the products, so Adhesive usually chooses 3M or Nitto, and the panel material often chooses AM series or antibacterial Silicone Rubber material. And marine equipment should consider waterproof and resistance more often. Ultraviolet rays. Waterproof structure is required for waterproofing, and UV-resistant materials such as XE series or HP92W should be considered for UV resistance. This information can confirm most material choices.
    • Specific color number: Different color numbers are different. If there is no specific color number, the overlay cannot be completely designed unless the customer informs that the color can be customized. The commonly used color number is Pantone or RAL. If it is a special color, the customer can also send the color patch to let Niceone-Keypad match it.
    • Editable document: including size, color number, circuit principle, vector graphics is the best project document.
    • Master samples:If the customer cannot provide any documents, Master samples are also possible.

    A good drawing requires the cooperation of customers and suppliers. Niceone-Keypad hopes to save users’ time and cost after providing Proof as soon as possible. This also requires the cooperation of customers.

    If the customer feels that it takes too long to manufacture samples, Niceone-Keypad has the following suggestions:

      • The material is best to choose more conventional
      • If the sample is particularly urgent, you can consider using laser cutting
      • Printing uses the printing method.
      • If the product has Embossing, you can consider CNC etching abrasive tools. In this way, the sample can be completed in about 5 days.
  • 7. What are the common problems of Graphic Overlay Panel?

    The panel window is scratched: If the panel window is found to be scratched before using the Graphic Overlay Panel, it may be caused by the following situations.

      • Reason 1: There is no protective film attached to the Overlay window of the Graphic Overlay Panel.
      • Reason 2: The panel window is scratched during the mounting process.

    If it is caused by scratches on the panel window during use, the main reason is: no hardening material is used.

    Solution: If the Graphic Overlay Panel comes with a window, a protective film should be attached before use. The QC department should check the panel window during the placement process. At the same time, the Graphic Overlay Panel with window is best to use hardened and scratch-resistant materials such as EBG, single-sided hardened PC, hardened glass, etc.

    Embossing deviation: Customers sometimes find that the Embossing of the Graphic Overlay Panel is a deviation

      • Reason 1:Embossing mold is not calibrated.
      • Reason 2:The silk-screen panel is not calibrated.

    Solution: QC and engineering need to check molds and silk screen panels. This can solve this problem to a large extent.

    Resin Dome is dirty: The raw material of Resin Dome is glue A and B. The situation of dirt and water streaks mainly depends on the environment and the way of standing.

    Solution: It needs to be deployed and glued in a dust-free workshop. At the same time, use the grid board to stand the Resin Dome and make it solidify.

    The ink adhesion is very poor: The ink peeled off during use of the Graphic Overlay Panel, or the ink peeled off during transportation.

      • Reason 1: The ink is not compatible with the material, and it is necessary to select a suitable ink to print.
      • Reason 2: The 100 grid test was not performed.
      • Reason 3: The printing method and heating time are insufficient.

    Solution: It is necessary to choose the ink with good compatibility with the material. For example, the adhesion of PET ink will be better if PET is used. But this requires the experience of the manufacturer. If the 100 grid test fails, you need to consider re-creating the Graphic Overlay Panel, and the 100 grid test needs to be performed before and after printing. Choose the appropriate printing method, and the heating time is selected according to the characteristics of the ink.

  • 8. How to print Graphic Overlay Panel?

    There are two common printing methods for Graphic Overlay Panel: Screen printing or Digital Printing. Both of them are excellent printing methods, but both have their own advantages. These processes provide visual elements for graphical overlays and improve usability by creating visual cues and labels for different functions on the user interface.

    Screen Printing: It is often used for polycarbonate (LEXAN) or Polyester materials. When the quantity is less than 500pcs, the cost of Screen printing is more affordable than that of Digital Printing. The color of Screen Printing is mainly based on RAL or Pantone color number. At the same time, the color error of Screen Printing is small and easy to proofread. Screen Printing also acts on the use of conductive inks. Silk screen creates more durable and longer lasting products. In screen printing, the ink is applied in heavier and thicker layers to obtain more vivid and vivid colors. The cover layer is usually “back-printed” or “printed on the secondary surface” to increase durability.

    Digital Printing: mainly uses the color collision of CMYK to form a complete color system, suitable for gradual effects, Graphic Overlay Panel that requires a large number of colors to be displayed, or Graphic Overlay Panel for mass production. However, Digital Printing is printed on Polycarbonate or Graphic Overlay from Polyester. Panels are usually lighter or translucent in color, and white ink needs to be printed on the back of the material to make the color thicker. At the same time, the price of Digital Printing will be more affordable when users need large quantities of Graphic Overlay panels.
