Printer in Dubai - the Digital printing revolution

The Digital printing revolution arrives in Dubai

We all know how the computer revolution has changed the way we work and live  and of the subsequent effects it has had on our lives.   Similarly the same computers are radically changing the norms in the printing industry too and this revolution is called Digital printing.



In the early fifteenth century, the first printing press was developed by Gutenberg. During those early days it was a very slow and expensive process to print anything and the demand for a way to quickly print short run material in an inexpensive way was quite high. Before computers, it was next to impossible to print short run four color material, since the set up costs, not to mention the set up time that added to the material costs, was very high.

The marriage of the old technology i.e. the printing press and the new technology computers, created a new and exciting area of printing Digital printing technology.  This new technology with a paradigm shift in printing technology makes what was thought inconceivable, possible.  This merging of the old and new technologies, has forged together the exact solution that print customers world over needed, something that the industry cannot do without now.

To understand digital printing better, let us understand analogue printing first.  Conventional traditional printing is analog in nature, where analog is defined as a continuously varying event such as pressure, or sound, whereas a digital system relies on an on or an off signal, thus making it more predictable.  With traditional offset printing, images are reproduced by creating a copy technically referred to as a “analogous” image.

Offset printing or Lithography uses copies of images on a hard substance (mostly metal plates) to transfer ink to print substrates (mostly paper).  Similarly in screen printing, positive films and stencil negatives are used to resemble the original image to create prints.  Similarly processes like flexography, gravure, etching  and similar analog print methods use other forms of image transfer that is primarily analogous in nature.  All of these analogous methods, use a reproduced  image(s) from the primary image. 


So how does digital printing really work?  With digital printing each image to be reproduced is assembled from mathetical formulas and a complex set of numbers.  Thus the process of digitizing of images means capturing images using a matrix of dots commonly known as pixels.  The digitized images then forms the basis for a reproduction by a digitally controlled deposition of ink, toner or even exposure to electromagnetic energy such as light thus reproducing images. 


The numbers and mathematical formulae also allow the possibility of algorithms to compress the date which has made possible a method of calibration of images and color management systems which help keep the images looking same no matter where they are reproduced.  Adobe Inc. has also developed a common language for digital printing called PostScript.  To see what PostScript looks like, try to view a PDF or EPS file in a text editor.  Though the coding seems very complex and intricate, to a computer it is just a yes or no instruction.

Digital printing offers several great advantages including quicker response time and a multi color registration system that eliminates several of the set up processes, saving a huge amount of time. Another great advantage is the ability of Digital printing to handle variable data printing, meaning that each printed piece can have unique information, paving the way for personalized and customized printing that will just not be feasible with the conventional analog process of offset printing. 


Hence the main advantages of Digital printing are as follows :- 

  • Quick Turnaround
  • Shorter print runs
  • Variable data printing
