Built-in CISS
The availability of a
built-in CISS in the design of a device — a continuous ink supply system. Instead of cartridges, such plotters use external ink tanks, where the ink is pumped to the print heads. This allows you to reduce the cost of consumables: one refill of CISS is much cheaper than several replacement cartridges for the same print volumes. And you have to refill such systems less often than changing the cartridge.
Number of cartridges
The number of individual cartridges the plotter needs to operate.
Each cartridge is responsible for its base colour used in printing. Monochrome plotters (see "Output Type"), by definition, use only one cartridge, for black colour and for such devices this parameter is usually not specified at all. But in colour printing, where all available shades are obtained by mixing basic colours, the number of such colours (and, accordingly, cartridges) can be different.
The most modest of modern colour plotters are designed to work with
4 or 5 cartridges. The first option corresponds to the CMYK colour scheme with 4 basic colours — this is the minimum required for full colour printing. In turn, 5 cartridges usually mean a CMYK colour scheme, supplemented by a separate supply of black ink for monochrome images — this allows you not to waste consumables for such images that may be needed for colour prints, and also to print monochrome even with empty colour cartridges, and vice versa.
In general, these sets of basic colours are inexpensive, while they are able to provide fairly good quality prints; so plotters for 4 – 5 cartridges are very popular nowadays. However, the use of additional basic colours can significantly increase the quality of the image, primarily the reliability of colour reproduction. Thereby, advanced plotters can provide a larger number of cartridges —
6 – 10, and s
...ometimes more. Such devices are quite expensive and difficult to maintain, but they are indispensable for printing materials with high requirements of colour quality.Cartridge model

Main unit dimensions (WxDxH)
Dimensions of the main unit of the device. For desktop models (see "Placement") this is the total size of the entire plotter, it is a spec you need to focus on while choosing a model and evaluating a place for installation. For floor-standing devices, the dimensions are indicated here without taking into account the stand, so this parameter plays a minor role and can be useful mainly for storing or transporting the device in disassembled form.
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.
