How Does Thermal Printer Color.

How Does Thermal Printer Color.
The greatest desire of all printer manufacturers would be a color printer is fast and affordable. Although the
color printers are becoming more agile, smaller and more affordable, the very nature of combining colors
on a single sheet of paper automatically makes this already complex process.
Whenever looking for a color page printed, you will be seeing a complicated arrangement of only four colors - cyan (blue), magenta (red), yellow and black. (Sometimes black is not included because the printer is capable of generating Black - not always fully satisfactory results - combining equal intensities of the other three colors.)

If you do a thorough examination on a small section of a printed color page you will see a series of colored dots.
As each printed color is composed of at least three separate colors, each page must actually be printed by
least three times. The time needed to perform all of these mechanical movements, still add up time
processing that the program requires to find the right mix of colors and send instructions to the printer,
resulting in a process invariably slow.
Some of the first color printers were based on variations of techniques used in traditional prints
black. The impact dot matrix printers use ribbons with three or four bands colored ink. Printers
inkjet printers use three or four print heads, each accompanied by a color ink cartridge. The
more recent development was the color laser printer that has separate cartridges for each color that goes to
paper.
The peripheral for color most used professionally today is the thermal printer in color. The
printing process creates bright colors because the paint used does not blur the other and neither is absorbed by papers
special textures. There were other advances in color printing, but for now, the pattern is still the thermal printing.
