Digital printing is a term that encompasses a lot of different equipment that produce different products and different levels of quality and expectations.
First let’s start with the term digital printing:
Digital printing’s definition is taking an electronic file and directly from that file creating your final output without going to plates or any other type of intermediary step or proof. It can be black or color.
The black is usually done by copiers on the low end and machines such as the Xerox Docutech or the Kodak Digimaster. These machines are capable of @ 100 copies a minute. Even these machines use toner although they are capable of higher resolutions than copiers. Although, higher quality than copiers the docutech & digimaster still don’t rival true offset quality of true offset presses.
The reasons these machines evolved and have become so popular is the ability to do low quantities at reasonable costs. They are limited as to the products and substrates that customers will use these machines for.The evolution of doing this same thing to color was a natural evolution. The higher the quality the better it could replace offset on the low end of the quantity spectrum.
Also as color digital printing machines improved customers deemed quality acceptable for more and more products and uses. Color copiers came first and use toner in the four base colors of CMYK to reproduce color photographs and images. The quality is on the low end for color and is susceptible to scratches and rubbing more than liquid ink. Then there is the classification of digital presses. There are toner and two types of liquid ink presses.
All of these color machines have strengths and weaknesses like any other kind of manufacturing process. Toner based machines are the IGen3 and the Nexpress. The quality is much better than color copiers but can still have toner look to them and sometimes don’t print smooth screenes. The only true offset entries are either Heidelberg or Ryobi machines. These actually produce temporary plates to produce the print job that is on press at that time.
This is true offset printing but has some limitations because the vast % of machines are small format and don’t have the ink carrying capacity that larger presses do. These machines also can’t print variable data printing where the image or text can be changed from sheet to sheet. The other liquid ink machine is the HP Indigo family. The Indigo 3050 can print variable data while rivaling offset quality.
The Indigo digital press family is the only machine that can print variable data as well as being capable of printing PMS spot colors as well. Customers will use this machine to print postcards, brochures, posters, sales sheets, flyers and any other printed product. These are your choices in digital printing. As final users have continued decreasing quantities of their orders and use more and more of customized marketing digital printing’s market share has increased. It is a powerful option to promote your business from small startups to large corporations.
