Deciding On Offset Printing Is Still An Environmentally Friendly Alternative

These days digital printing presses are getting the lion’s share of attention in the print world, offset printing is still extremely common because there still remains a lot of benefits to be acquired from the offset presses that digital printing presses cannot provide.

Offset printing is a style of printing where ink is deposited from a photo-imaged plate to a rubber blanket and then onto the substrate being printed. Offset printing presses hail from as far back as the 1870s in England, while a different version was developed in the United States in the early 1900s.

Compared to other techniques of printing, offset printing happens to be very well suited for creating large quantities of high quality print in a cost-effective way, and with very little in the way of maintenance or oversight. Some of the most commonly off-set printed products include: newspapers, brochures and books.

The standard for new offset printing presses utilize CTP (Computer-To-Plate) imaging technology which provides higher quality results than the older systems that use film to image the printing plates. CTP (Computer-To-Plate) allows for the imaging of the printing plates without the need for film, which then eliminates stripping, compositing and other traditional plate-making procedures. CTP (Computer-To-Plate) has been a revolution in the printing industry which has led, in turn, to faster prepress time, reduced labor costs, and higher quality of print.

Some of the advantages to offset-printing include:

-    Consistently high quality reproductions.
-    Printing plates are made quickly and easily, and the plates are more durable.
-    Cost-effective: off-set printing provides the most cost-effective print when large quantities are required.

On the negative side to offset printing is the amount of materials and the time needed to prepare for each print job, which is commonly referred to as ‘make ready’. As a result of this, smaller print jobs are being done on digital printing presses.

There are a number of different ways which offset printing presses can be categorized – one of which is how the paper stock is fed into the machine – either Sheet Fed or Web Fed.

-    The term sheet fed describes each individual sheet of paper or paperboard being fed into the printing press one at a time. Typical products that would be produced using this method are smaller run magazines, brochures and general commercial printing.
-    The term web fed describes to the use of paper roll stock that gets fed into the printing press. Common examples of web fed printed products are newspapers, magazines, catalogues and books that exceed 10 to 20 thousand impressions. Web fed presses are well known for their production speed, with some capable of running three thousand feet per minute or faster.

A very good example of a more modern offset printing press is the KBA 74 Karat 29 inch waterless offset press that is digitally integrated, which is considered to be one of the most eco-friendly printing presses in the world while delivering high print quality.

For a 29 inch printing press of this calibre, the KBA 74 Karat has a very compact footprint (12 foot 9” long, x 7 foot 3” wide, x 7 feet tall) and all aspects of the press are designed for operator ease and maximum efficiency. For example, the machine holds two cassettes of CTP plates (which is enough to produce ten orders) which get imaged and are automatically changed within the machine.

A complete job change with automated plate change, imaging and inking takes a surprisingly small amount of time (approx. 15 minutes), with no more than approx. 10 make-ready sheets. With a production speed as high as ten thousand sheets each hour, the waterless offset printing plates can produce projects of up to 100 thousand copies before a plate change is needed.

This press eliminates paper waste, ink sludge, toxic cleaners and chemical developers that are commonly required with offset printing. Through its use of soy based inks, totally waterless printing technology, and inline aqueous based coating, the KBA 74 Karat delivers the top quality eco-friendly print solutions you’ll find anywhere without having to sacrifice print quality in the least!
