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.Print speed
The print speed provided by the plotter.
Such devices are intended for large-format material, so this parameter is usually indicated as m² per hour. Keep in mind that the spec usually give the maximum print speed, which is achieved at a reduced resolution and overall quality; in standard mode, the plotter may work noticeably slower. So when choosing for this parameter, it is worth taking a certain margin. On the other hand, according to the values indicated in the specs, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed performance, usually, will proportionally correspond to the difference in the actual speed of work.
As for specific values, speed
up to 20 m²/h for modern plotters is considered low,
21 – 50 m²/h — medium, and in the most powerful and performant equipment this value can
exceed 50 m²/h.
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.
Max. roll diameter
The largest roll diameter that can be installed in a plotter with roll printing (see above). This parameter is useful primarily for the selection of media: the material of the same width can be produced in rolls of different diameters.
Paper grammage (max)
The highest paper grammage that the plotter can handle normally. For details about grammage, see "Paper grammage (Min)"; and you should pay attention to its maximum value if you plan to use thick materials. Do not try to print on more dense media than it is specified in the specs of the device: even if the plotter can handle such paper normally, it can cause serious damage.
Cartridge model
Models of cartridges used in the plotter. With this info, you can easily find original consumables for the device.
Built-in memory
The amount of built-in memory provided in the design of the plotter.
Such memory is used to store various service data: print tasks, settings profiles, etc. Due to this, the plotter becomes more "independent": for example, many models allow you to continue printing even when the master PC is turned off.
We emphasize that in this case we are talking about solid-state flash memory, which is used mainly for "operational" service information. The capacity of such memory is relatively low, it is measured in megabytes; but in addition to it, the design may include a larger storage capacity — usually a traditional hard drive. For more information about it, see "Drive Capacity".
Storage capacity
The capacity of
the built-in storage installed in the plotter.
First of all, we note that this drive should not be confused with the built-in memory (see above): in this case, we are talking about a storage designed for long-term storage of large amounts of data. Accordingly, such a storage differs from the mentioned memory in a larger capacity — its volume is already calculated in gigabytes. In addition, the built-in drive is usually a hard drive — this type of storage is better suited for the application described. Such a disk is intended mainly for storing various graphic files — footage, layouts for printing, data from a scanner (if available — see above), etc. The larger its volume, the more files can be simultaneously stored in the plotter's memory.
It is often more convenient to upload files into the device's memory in advance and send them to print directly from the control panel than to turn on the master PC every time — especially if you have to print often and a lot, and PCs are sometimes unavailable (for example, due to mismatched work schedules from printers and designers). On the other hand, such functionality is relevant mainly for powerful performant plotters, and the availability of a built-in drive significantly affects the cost. Therefore, this feature is found mainly in fairly advanced models.
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.
