Control keys
The number of control keys provided in the design of the tablet.
Each of these keys is responsible for a specific function, while the set of these functions can be configured: in some models they can be selected manually, in others the functionality of the keys changes automatically, depending on the currently active application. Anyway, additional keys allow the user to perform various actions without looking up from the tablet — this can be very convenient in the midst of the work process, when you don’t want to change the pen to the mouse again or reach for the keyboard. And the more control keys — so, respectively, more additional actions can be performed using the tablet. On the other hand, with relatively simple tasks, the abundance of additional buttons can hinder and confuse the user rather than help.
The most modest modern tablets provide
up to 5 control keys ; the most popular option is
from 6 to 10 keys, and in advanced models this number can reach
15 or even
more.
Touch strip
A touch-sensitive surface, usually located along one of the edges of the front panel of the tablet case.
The touch strip provides additional controls such as scrolling, zooming, canvas rotation, and other gestures that can be customized to perform different tasks. Thus, the strip can often be reprogrammed for certain actions, be it quickly switching between tools in a graphic editor or changing brush parameters.
Brightness
The maximum brightness in cd/m² that the device screen produces.
High brightness displays remain highly readable under intense ambient light, such as when the workplace is exposed to sunlight. A dull image on a graphics tablet screen can be “blown out” by such lighting. Note that a large margin for this parameter affects the cost and power consumption of the display.
Colour gamut (NTSC)
The range of colors that can be displayed on a graphics tablet screen. The parameter is indicated as a percentage relative to the coverage of the NTSC color space. The larger the color gamut, the wider the capabilities of the screen and the better the quality of its color rendition, which is extremely important when working with graphic materials.
NTSC is one of the first color models, launched in 1953 for color television. And it is still used to describe and compare matrices. The NTSC model covers a larger range of colors than the standard sRGB used in computer technology, so even a relatively small number of percentages corresponds to a fairly wide coverage. For example, a value of 72% or more according to NTSC is considered a decent indicator for use in design and graphics.
Colour space (Rec. 709 / sRGB)
The range of colors that can be displayed on a graphics tablet screen. The parameter is indicated as a percentage relative to the coverage of the Rec.709 or sRGB color space. The larger the color gamut, the wider the capabilities of the screen and the better the quality of its color rendition, which is extremely important when working with graphic materials.
Rec.709 and sRGB are the most popular modern color models: they have the same range and differ only in the area of application. So, sRGB is used in computers, and Rec. 709 - in HD television. In terms of the range of colors, these spaces are identical and the percentage of coverage for them is the same. In the screens of graphics tablets, the color gamut for the specified models can reach and even exceed 100% - these are the values that are considered necessary for correct work with graphic materials.
Colour gamut (Adobe RGB)
The range of colors that can be displayed on a graphics tablet screen. The parameter is indicated as a percentage relative to the coverage of the Adobe RGB color space. The larger the color gamut, the wider the capabilities of the screen and the better the quality of its color rendition, which is extremely important when working with graphic materials.
Adobe RGB was originally developed for use in printing and printing. Accordingly, support for this model and its wide color gamut are important in cases where a graphics tablet is used in the design and layout of high-quality printed products. It is important to take into account that Adobe RGB is wider than the popular sRGB model, and its percentage figures are smaller: for example, 99% of sRGB coverage is usually about 87% of Adobe RGB.
Pen model
The model of the pen that comes with the device. Allows you to understand which one is used and learn more fully its full characteristics. In this case, in the case of a replacement, you will already be aware of which accessory is needed for the purchase. However, nothing prevents you from replacing the existing one with a more advanced one, of course, if the graphics tablet itself allows you to work with a different pen model.
Max. reading height
The height within which pen movements above the working surface are recorded by the tablet electronics even in the absence of direct contact.
Many tablets allow you to work in a "non-contact" way — without directly touching the stylus to the work surface. Thanks to this, it is possible, for example, with a raised pen to bring the cursor in the graphics editor to the desired point and turn on the drawing mode by touching the tablet with the stylus. And the greater the maximum reading height, the more convenient it is to use this mode, the less demanding the tablet is for the accuracy of movements. In many modern models, this parameter exceeds 10 mm.
Pen angle
The maximum angle of the pen (relative to vertical) at which the tablet continues to perceive it as a working tool and respond to its movements. The larger this angle, the greater the allowable deviation of the pen from the perpendicular position and the higher the degree of freedom when working with the tablet.
