S I G N & D I G I T A L G R A P H I C S • July 2017 • 45 With direct printing, the printer deposits the dye-sub inks directly onto the fabric, which can then be run through a heat press—eliminating the need for a transfer process. Some direct- printing printers include a set of heated rollers (calender) that perform on-board sublimation. Dye sublimation produces an extremely permanent, high- resolution, full-color print. The prints will not crack, fade or peel under normal conditions. Plotters Plotters were the first type of printer that could print with color and render graphics and full-size engineering drawings. This technology is primarily used for producing CAD (computer aided design) and CAM (computer aided manufacturing) draw- ings. A plotter interprets data from a computer into line draw- ings on paper with one or more automated pens, (see Figure 7). The plotter can draw continuous point-to-point lines directly from a vector file. There are a number of different types of plotters the most common being: Drum Plotters—draw on paper wrapped around a revolving drum to create the vertical coordinates of the drawing. The pens move in a horizontal direction and draw on substrate. Flatbed Plotters—draw on paper placed on a flat surface with pens that move both horizontally and vertically. Electrostatic Plotters—draw on negatively charged paper with positively charged toner. Vinyl Cutters—though not actually a printer, a vinyl cut- ter uses plotter technology to accurately cut shapes from vinyl sheets. Printing There are many variables that need to be considered before you push the print button. Considering the amount of material that is consumed by large-format printing and the length of time it takes to print a large-format document, it is essential to get the print right the first time, otherwise a lot of time and money can be wasted. That about covers the types of large format printers and their characteristics and capabilities. There are many brands and sizes on the market and you should consider what system is best for your particular needs. In this article, I've presented the various types of hardware and media that prints large images. Next month's DigitalEye column will present important tips on how to configure and color manage your large-format printer and software to produce accurate, reliable color every time you print.
