A personal inkjet printer in the house was unthinkable 30 years ago for the average consumer. Back in the day, inkjet printers were too bulky and expensive to be something the average consumer would want in their home. However, in the intervening three decades, printers have become standard office equipment in virtually every private residence.
Is it true that you've ever pondered the inner workings of an inkjet printer and its ink? Changes in printer and ink technology over time are fascinating. You can avoid printer issues in the future by familiarizing yourself with the technology behind these devices.
Technologies for Inkjet Printing
Today's inkjet printers generally employ one of two inkjet printing techniques. The thermal inkjet process and the piezoelectric inkjet process are the two names for this technology. Canon and HP, for example, choose the thermal inkjet process, whereas Epson uses the piezoelectric inkjet method.
The printer uses heat to force ink from the cartridge's nozzles in a method known as thermal inkjet printing. When the printer ink is heated, tiny bubbles form inside of the cartridge and are expelled through the nozzles. When the bubbles pop, the ink makes contact with the printer. When a bubble bursts, it creates a vacuum that causes more ink to flow out of the cartridge, where it is heated and subjected to the same cycle.
The piezoelectric inkjet technique relies on the pressure provided by piezo crystals to force ink droplets out of the cartridge's nozzles. Ink is pushed out of the nozzles of the ink cartridge and more ink is drawn out of the cartridge to make the prints by the contraction and expansion of the piezo crystals when they are subjected to electric charges.
Performing Ink Processing
An printer processes its printer ink using a procedure called dithering. In dithering, a color pixel is split up into a succession of dots that can generate a spectrum of hues. The three primary colors used by inkjet printers are cyan, magenta, and yellow.
It takes a lot of precision to generate a dot when printing. The resolution of an inkjet printer is measured in dots per inch, and the number of layers of color graduations per dot is a measure of the print quality. Theoretically, the higher the resolution of the printer is and the bigger the number of graduations it can make, the better its print quality and better for photo booths.
Prints from an inkjet printer can have millions of colors, far more than the human eye is capable of seeing, because to the printer's resolution and color graduation. The range of colors that can be printed is variable from printer to printer. Photo-centric printers are focused on reproducing colors while inkjet printers for daily document printing emphasize printer resolution more than color graduation.
This is how an inkjet printer and printer ink works generally. Knowing the inner workings of your printer can allow you to utilize it more effectively and head off potential issues before they arise.
