Good Looks and Security, Too
Today, most organizations design and print themselves.
At the same time, there needs to be more concentration on the card and badge design. There are many elements involved.
ID CARD DESIGN TIPS
Consider the type of cards you’ll be printing on. You may need to design your card around an embedded security feature, smartcard contact chip, a magnetic stripe or barcode. If you’re using a reverse transfer printer, take advantage of its print quality by using colorful imagery.
How much printed information will your cards contain? Make a list of the data specifications your cards will need so you’re sure to include all necessary elements in your design. Consider printing information not necessary for visual ID on the back of the card. This will also keep the front of your card uncluttered, easier to read, and more professional looking.
ORIENTATION AND USE
Graphic design is important. A well-designed card will support and extend your brand, representing your brand not only to your cardholders, but also to visitors and anyone else who sees them. In addition, how many times have you seen people wearing ID cards while out to lunch or running errands?
Bright, saturated color looks best printed on PVC cards. Light colors tend to look faded or washed out. Also be careful of the amount of dark color used. Consider using a custom or stock image, illustration or other design or texture as a background -- make sure to use high resolution, print quality images (300 dpi). Stock imagery is easily available online at a reasonable price and can take cards from looking elementary to looking professional.
Print quality counts. Reverse-transfer printing technology provides the best print quality available in card printing. Reverse transfer printers provide photo-quality printing and, unlike printers using direct-to-card printing technology, they are capable of printing on the entire surface of cards. Direct-to-card printers aren’t capable of printing right up to the edges of cards. They can leave a small but noticeable unprinted border around the entire card. Reverse-transfer printers are even capable of high-quality printing on technology cards, like proximity cards with internal antennas that make the surface of the card uneven and difficult for direct-to-card printers to print on. They can also print right up to the edges of the exposed chip on a contact smart card.
Test the printing for quality. You’ll never know exactly what your cards will look like until you test print them on your card printer. Dye sub printing on PVC outputs color differently than printing on paper with an inkjet printer. Your printer drivers will allow you to make adjustments that will affect the print outcome—adjusting settings can change the intensity of color on your cards, for example.
UNDERSTAND PRINTER CHOICESBefore you purchase a printer, design a card and start production, there are a few things you should know about the printers. The type of printer you choose will depend largely on the type of card you plan to use, how many cards you plan to print, how often you need to print cards and what printing elements you need to incorporate into your card. There are five major factors to consider.
THE PHYSICAL PROPERTIES OF THE PRINTER
EASE OF USE
THE TYPE OF PRINTING
Thermal printing -- Like all other desktop printers in the office, today’s photo ID printers are digital. In the years since the first dot matrix printers arrived on the scene, we’ve become used to text and images composed of tiny dots - picture elements or pixels. Early results were not impressive, due to the print head’s then-limited resolution, measured in dots per inch or dpi. With today’s resolutions, the problem of jagged edges is largely a thing of the past.
Most photo IDs are printed by digital thermal transfer, a process by which color is transferred from a single-use ribbon to various kinds of receptor materials. There are two distinctly different thermal transfer technologies: dye sublimation, using the three process colors yellow/magenta/cyan for photo-realistic images, and mass transfer, for machine readable text and barcodes (usually in black). Both technologies use a stationary print head comprising a row of closely spaced resistive elements — tiny heaters, independently energized by the printer controller. Sandwiched by spring pressure between the print head and the receptor is the inking ribbon, which may be either a resin-coated film for mass transfer, or a series of process-color dye panels for dye sublimation.
The receptor card is driven through the print station, with the ribbon metered out at the same speed from the supply roll.
Dye sublimation printing – The variable size and density of each color dot is the secret to the photo-quality printing possible with dye sublimation – bright colors and no jagged edges. Dyes penetrate the receptor. Color migrates from the dye ribbon into the surface. The spread of the dye dot (its amount of diffusion) depends on the amount of heat applied by the printhead element. On reaching a dye panel boundary, the printhead is lifted to allow the card to back up. The head then lowers to print the next color.
Mass transfer printing -- With a mass transfer panel, the printer cannot control either the ink dot’s size or density. It’s either there or it isn’t, which is not good for continuous tone images such as photographs. To create the illusion of continuous tone from discrete dots of ink, printers use a process called dithering, exactly the same behind-the-scenes operation your computer performs anytime it sends a picture to the office laser printer.
A mass transfer ribbon is a layer of monochrome resin, usually black, on a thin backing film (also called black resin printing). When heated, the resin is stripped from the backing and deposited as a physical layer on the receptor. Mass transfer delivers sharp text and graphics plus infrared readable barcodes. Photo reproduction is adequate for many applications calling for high printing speed and low cost.
Understanding the basic elements of a high-quality ID card and the fundamentals of the printing process, security executives can better choose the right printer for the specific application.
