Number of colors
The color palette that the printer can print.
A large number of colors is required for high-quality photo printing and obtaining color prints with many shades. The standard is
4 colors.
Ink type
— Pigment. Ink based on pigments — solid dyes, which are diluted in the form of microparticles in a liquid filler to a state of suspension. Compared to more popular water-based inks, these formulations are noticeably more expensive, and the finished image may turn out to be somewhat less bright (compared to printing with water-based dye on the same printer). On the other hand, pigment ink gives higher detail, which is especially important for photo printing. In addition, finished images resist moisture better and do not fade as quickly in bright light — this resistance is not enough for outdoor use, but indoors such prints can be stored for a very long time.
- Water soluble. Inks based on water-soluble dyes allow achieving high realism of color reproduction in color printing, they are well absorbed into the deep layers of paper and are cheaper than pigment ink. Also, water-soluble ink does not dry as quickly in the cartridge or print head of the printer. They are recommended for use with inkjet paper - ordinary thin paper strongly absorbs dropsy, which can cause ink to show through on the back of the sheet. At the same time, water-soluble inks are afraid of moisture and direct exposure to ultraviolet rays - when water gets in, the paint “floats” on paper, and it fades under sunlight.
– Pigmented / water soluble. Some printers have a print head that allows you to print with two types of ink at once. A common case is when their black cartridge is filled wi...th pigment ink, and the color one is filled with water-soluble ink.
Cartridges
The number of ink cartridges required for the full operation of the printer. In black and white devices, usually, one cartridge is installed. For colour printing, at least 4 colours are required (CMYK colour scheme), however, cartridges in such devices can be installed as 4 (one for each colour), or only 2 — black and "colour". The latter is essentially three multi-coloured cartridges in one case; This design somewhat reduces the cost, but creates certain inconveniences: when the supply of ink of one colour is exhausted, the entire colour cartridge becomes inoperative. However, this disadvantage is not critical if the possibility of refueling is provided.
Printers designed for more than 4 cartridges are also available. This design means that this model uses one of the extended colour schemes; this, on the one hand, contributes to high-quality colour reproduction, on the other hand, it significantly affects the price. In the most advanced photo printers, the number of cartridges can reach 9.
Cartridge model
The types of cartridges (both black and white and colour) used in the printer. Some printer models are able to work with "non-native" cartridges, but this feature usually refers to undocumented features, and the manufacturer's warranty covers only specific types of cartridges. So use "non-native" models with caution.
