What is Digital Duplicating?
Ten years ago digital duplicating equipment was not available in the United States. Five years ago, use of the technology was spreading rapidly, but mostly in a few small vertical market niches. Today, it's grown beyond those limited uses to general acceptance in many industries and organizations. Yet, it's still not as widely known or used as photocopying. The technology provides copies just like xerographic copiers do, with tremendous advantages in cost, speed and reliability. So why doesn't everyone have one? Is it a technology that could benefit your organization? To answer those questions effectively, you need to know a little about the technology.
In simple terms, the digital duplicator looks and operates like your everyday office copier, but inside, the technology works more like an offset press. Digital duplicating blends three very reliable, high-quality printing technologies into one easy-to-use, compact system:
The blend of these three technologies provides a system, which prints high-quality documents like those done on a press, at the touch of a button, and for a fraction of the cost of copying.
- Digital Signal Processing
- Push-Button Electronics
- Ink-On-Paper Imaging
Inside the equipment, the process is clean, quiet and simple. The digital duplicator captures an image digitally and then automatically creates a master, which is like a plate on the offset press. Next, ink is applied to make a copy. The diagram shows how this works in more detail. The result is a system with higher reliability and lower costs than other technologies. So why doesn't everyone use digital duplicating instead of copying? Well, there is one catch. The cost of the master, usually around thirty cents, makes the digital duplicator impractical for less than 20 copies of a page. The majority of copy jobs (memos, letters, reports, faxes, spreadsheets, etc.) made in a typical office are between one to three copies per page.
Digital duplicating equipment is best used for mid to high volume office copying jobs. And, it can reduce the amount of printing done on offset presses, either through an in-plant print shop or on jobs sent to outside vendors. The advent of desktop publishing and "On Demand Digital Printing" has also created opportunities for the growing use of digital duplicating. As its name implies, digital duplicating technology is digital, and as a result, is connectable to PCs and networks. It also offers the advantage of printing in spot color - that is two or more separate colors per page (as opposed to full process color used for magazines or brochures).
Common applications for digital duplicators include newsletters, forms, memos, fund-raising or marketing solicitation materials, training materials and manuals, flyers and many others. The main requirement for economic use of the technology is that run-lengths (copies per page) are twenty or more. The longer the run-length, the greater are the cost savings versus photocopying. As you can see from the cost per copy chart, the savings grow with each copy made on a digital duplicator, compared to the typical copier. The duplicator can also save money compared to an offset press, which requires much longer run-lengths to be practical economically. Per copy costs on the duplicator can drop well below a penny per copy with long enough runs.
Choosing the Right Digital Duplicator
There are a few key specs that you want to pay attention to when purchasing a digital duplicator. The following is list of recommended specifications. Obviously there will be special requirements based on your needs but this will be a good basis for comparison to a standard digital duplicator.
Time to First Copy:
This is the amount of time it takes the machine to make the first copy. After that, every other duplicate comes out faster. Better machines perform at no more than 26 seconds for the first copy.
Variable from 60 to 120 copies per minute
Scanner Resolution (dpi):
Resolution is measured in dots per inch. It is not wise to have less than 300 dpi if you want to have high quality duplications
It is best to have a flatbed, glass platen to easily copy loose papers or pages from a book
Copy Paper Size Minimum
It is standard to handle 3.6" x 5.9" paper
Copy Paper Size Maximum
It is standard to handle 11 x 17" paper
Paper Weight Minimum
It is standard to accept 13 lb paper stocks
Paper Weight Maximum
It is standard to accept 110 lb paper stocks
Paper Feed Capacity
This is the amount of paper the machine can hold without reloading. Less than 1000 sheets @ 17.6lb. Bond paper will require more maintenance especially with large runs (the way digital duplicators are meant to be used)
Image Area Maximum
Not less than 9.8" x 13.7"
Should hold at least 600cc to avoid constant maintenance
This is the number of colors and combinations your duplicator has the ability to print. It is not wise to have less than sixteen for nice sharp colors
