Go Beyond What's Enough

When it comes to effective ID card design, Joseph Wright of Fargo Electronics, Minneapolis, Minn., has some sage advice. These days, he says, a color photo on a white card just isn't enough. There is a good reason for that - it is just too easy to duplicate. Proper card design can help reduce this vulnerability. Incorporating security elements that are difficult to forge, yet easy to authenticate should be the first consideration in a secure card design. The most basic element of a secure card is a color photograph. Beyond photos, employee numbers, barcodes, or other identifiers printed on the card, there is a huge range of visual elements that add security.
Holography is the most prominent visual security technology used in today's ID card applications. Today, holograms used on ID cards can be loaded with high-tech, layered security features. Complex nanotext and fine-line, microscopic printing, as well as optical variable devices like morphed and animated images are extremely difficult for counterfeiters to reproduce, according to Wright.
Holograms are most commonly seen in overlaminates, a clear film applied to a printed card's surface. Overlaminates can contain an off-the-shelf holographic design, or a custom design for even greater security.
Smart cards with exposed microprocessor chips need a design that accounts for that structural difference in the card surface. Since most traditional direct-to-card printers don't print tightly around a smart chip, build an unprinted area into your design to accommodate the space the smart chip will inhabit. Cards with internal electronics, like contactless cards or "clamshell" proximity cards may pose difficulties for traditional card printers. Test your card design with the printer you'll be using to ensure that the surface irregularities of the card don't present any surprises during card production, suggests the Fargo executive.
Alternatively, consider reverse image printing technology. In reverse image technology, the printer first prints images onto a special film that is then fused into the surface of a blank card through heat and pressure. Because the printhead in a reverse image printer prints only on to the flexible film and not the card surface itself, these cards do not suffer image quality problems due to surface irregularities.
Once the visual security and functionality layers have been determined, designing the card graphics comes next.
To begin the graphic design process, some find it helpful to divide the card into a grid, placing the fixed elements (i.e., smart chips, visual security elements or logos), into position first. Determining whether the card orientation will be horizontal or vertical is important, as is determining the size and relationship of the identifying elements such as photo, ID number and signature. One factor companies often overlook is whether or not there will be a hole punched in the top of the card to accommodate the badge clip. If so, it is important to allow for it in your design.
Don't be afraid to use color, but avoid very dark colors because they affect readability. Likewise, pastel backgrounds can look washed out. Bright, primary colors work best. Consider using a textured background rather than a solid color to minimize surface flaws.
For most ID cards, the photo is the primary feature. That's why it is important to use high-resolution images (at least 300 dpi) and to make the photo as large as possible.
