Paper size
The paper size the plotter is designed to operate with. Most models use ISO 216 formats, identified by the letter A followed by a digit. These formats include the popular A4, but plotters usually work with larger paper:
- A0+. This marking means that the plotter is able to work with sheets larger than A0 (see below). The A0+ format itself provides a sheet width of 914 mm, however, in this case, support for wider media is usually provided — about 1100 mm (1050 – 1150 mm) in the most modest models of this format ( A0+ 44 ") and 1500 mm or more in the largest ( A0+ ≥ 60")
- A0. Paper of this format has a size of 1189x841 mm.
- A1. Paper size 841x594 mm — in other words, half of the A0 format.
- A2. A sheet of this format is approximately the size of a newspaper spread — 420x594 mm, half the size of A1. Considered relatively small by plotter standards.
- A3. The smallest format found in modern plotters: 297x420 mm, that is, only twice the standard A4 (in other words, with a magazine spread). Used in few desktop models (see Installation) — particularly, textile devices (see Product Type) for printing on T-shirts and other similarly sized clothes.
It is also worth noting that many models are able to work with other sizes. Moreover, we are talking not only about reduced, but also about la
...rger options: the maximum media width (see below) often exceeds the standard paper size.Scanner
The presence of a built-in
scanner in the plotter.
This function actually turns the plotter into an MFP (multifunctional device): the scanner allows you to digitize printed materials, as well as use the unit as a copier (however, this possibility should be specified separately). At the same time, built-in scanners, like the plotters themselves, are usually designed for large-format media. In addition, such equipment can be combined with various additional features — in particular, some devices with a scanner can not only send digitized materials to a PC, but also save them to a flash drive or memory card, and even send them to e-mail, network storage or an Internet resource.
Sheet printing time
Approximate time taken by the plotter to print one sheet.
This indicates for the paper size that the machine was originally designed for (see "Paper Size"). And it is approximate because it is usually given for optimal or almost optimal printing conditions: low quality and resolution, relatively simple images, etc. So the actual print time of the sheet may differ from the claimed one in one direction or another, depending on the operating parameters — starting from the mentioned quality and resolution to the type of media. However, according to the figures indicated in the specs, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed time, usually, will proportionally correspond to the difference in the actual printing speed.
It is also worth noting that this time is usually indicated by the duration of the printing process itself — from the capture of the sheet by the feeder to the output of the completed print from the device. Interruptions inevitably occur between printing individual sheets, so that the total printing time is longer than the printing time of a sheet multiplied by the number of sheets. For example, a device with a time consumption of 36 sec per sheet theoretically should print about 100 sheets per hour (1 h = 3600 s, 3600/36 = 100), but in fact such a plotter usually produces about 70 – 75 sheets in this time.
Media width (max)
The largest width of paper or other media that the plotter can handle. The larger this parameter, the larger the materials that can be printed on the device; however, the dimensions, weight and cost of the plotter also increase markedly due to this.
Number of rolls
The number of rolls that can be installed in a plotter that can print from such media at one time (see above).
Most often, such models are made for one carrier, however, there are also more advanced units — for
2 or more rolls(in some cases this number reaches 4). The meaning of this functionality is that you can simultaneously use media of different sizes (for example, A1 and A2) or/and types (for example, glossy and matte paper) while printing. Of course, you can only print on one material at a time; however, the presence of multiple rolls allows you to switch between them simply through the settings of the plotter, without fiddling with changing media.
Noise level
The maximum noise level produced by the plotter during operation. The lower this indicator, the less inconvenience to others the device will create. At the same time, in modern plotters, the noise level usually does not exceed 60 dB, which is comparable to a TV set at an average volume; and many of them do not "reach" even up to 50 dB, corresponding to a quiet conversation at a distance of 2-3 m. And if we also take into account the fact that plotters are usually used in industrial premises, then we can say that in most cases this indicator does not play a significant role.
Power consumption
Rated power consumption of the plotter. Usually specified by the maximum value — for the print mode, when the device requires the most power.
The heavier and more performant the device, the higher its power consumption in general. At the same time, models that are similar in performance may differ in this indicator. And here it is worth proceeding from the fact that a more energy-efficient unit usually costs more, but with intensive use, this difference can quickly pay off due to energy savings.
In addition, the power consumption may be necessary for special electrical calculations — for example, determining the necessary parameters of a voltage stabilizer, a backup generator, etc.
Dimensions with stand (WxDxH)
The overall dimensions of the floor plotter (see “Placement”), including the stand, in other words, the dimensions of the device in the operative condition (in addition to the stand itself, other equipment, such as trays for printed materials, is taken into account here). This indicator is worth evaluating how much space is needed to install such a plotter.
Weight
The total weight of the plotter is usually listed without ink and paper. You should pay attention to this parameter foremost when choosing desktop models (see "Placement"): modern plotters are quite massive, which puts forward corresponding requirements for stands for them.
