Such tools allow desired card and decal shapes to be cut out very precisely, and repeatably.Ī number of printer control languages were created to operate pen plotters, and transmit commands like "lift pen from paper", "place pen on paper", or "draw a line from here to here". In recent years the use of cutting plotters (generally called die-cut machines) has become popular with home enthusiasts of paper crafts such as cardmaking and scrapbooking.

Those computer software programs are responsible for sending the necessary cutting dimensions or designs in order to command the cutting knife to produce the correct project cutting needs. The cutting plotter is connected to a computer, which is equipped with cutting design or drawing computer software programs. Illustration of the layers of flex and flock foils (used in textile printing): carrier foil, colour coat & covering layer (including hot melt)Ĭutting plotters use knives to cut into a piece of material (such as paper, mylar film, or vinyl film) that is lying on the flat surface area of the plotter. Electrostatic plotters are very fast with plotting speed of 6 to 32 mm/s, depending on the plotter resolution. The resolutions available may be 100 to 508 dots per inch. This head traverses over the width of the paper as it rolls past the head to make a drawing. The plotter head consists of a large number of tiny styluses (as many as 21760) embedded in it. The electrostatic plotter uses the pixel as a drawing means, like a raster graphics display device. Electrostatic plotters were made in both flat-bed and drum types. The quality of image was often not as good as contemporary pen plotters. They were faster than pen plotters and were available in large formats, suitable for reproducing engineering drawings. Such devices may still understand vector languages originally designed for plotter use, because in many uses, they offer a more efficient alternative to raster data.Įlectrostatic plotters used a dry toner transfer process similar to that in many photocopiers. Pen plotters have essentially become obsolete, and have been replaced by large-format inkjet printers and LED toner-based printers. Plotters offered the fastest way to efficiently produce very large drawings or color high-resolution vector-based artwork when computer memory was very expensive and processor power was very limited, and other types of printers had limited graphic output capabilities. They are often incapable of efficiently creating a solid region of color, but can hatch an area by drawing a number of close, regular lines. Pen plotters can draw complex line art, including text, but do so slowly because of the mechanical movement of the pens. This means that plotters are vector graphics devices, rather than raster graphics as with other printers. Pen plotters print by moving a pen or other instrument across the surface of a piece of paper. Digitally controlled plotters evolved from earlier fully analog XY-writers used as output devices for measurement instruments and analog computers.
