The process of Printing is a fascinating one. How a spray of ink droplets turns into amazing prints. In case of printing WYSIWYG holds true. WYSIWYG is the acronym popularly used for “What You See Is What You Get”. In the case of printing techniques the output print is the same as displayed on the screen. Such is the power of modern day printing.
An Inkjet printer works simply by spraying droplets of ink on the print media. This is done using specially designed printheads. The printheads have Micro Drill Holes on the surface facing the print media and using piezoelectric or thermal Ink Dispersion Systems release droplets of ink from these micro drill holes.
HP inkjet designjet 500 make use of ink dispersion systems based on thermal techniques. HP 500 is one of the foremost wide format printers to be ever introduced in the market and produces high definition outputs at fascinating speed.
Ink used in the printing process plays an important role in determining the quality of the output as well as the application of the finished product in the real world scenario. A variety of inks are available and each of them has specific properties to make them adapt to the environment where the product would be used. For outdoor printing applications UV resistant, inks are used to prevent fading over time while for high gloss printing these are not preferable as they have a matt finish. The choice of ink also depends on the media being used for printing and the process involved in generating the print.
Inkjet printing is one of the most revolutionary techniques ever developed and used in mainstream printing. It is still undergoing iterations every now and then and getting better with time.
