The whole process of printing has undergone a major transformation in a relatively short period of time. With the invention of digital presses, there is the option of using a computerized process instead of an industrial one. This has eliminated much wastage of resources, time and energy. Choosing to use digital printing that is eco friendly takes this a step further.

Chemicals are used to engrave plates with images and text for offset presses. Ink and water are applied to the plate which is mounted on a roller. The plate cylinder offsets the design onto a rubber blanket roller, which in turn transfers it onto the paper. The entire process involves much wastage of resources and hazardous solid and liquid waste and fumes are produced as a by product.

The new technology does not require plates, eliminating many problems. Chemical usage and hazardous waste are significantly reduced. More personalization is possible and turn around times are faster. The process is particularly suited for items like business cards, letterheads and promotional material requiring small runs. Some other advantages are that overprint is reduced and there are no storage costs.

The first digital presses made did not produce the same quality as offset presses but this is changing as technology improves. If you are looking for top quality, it is important to use a supplier with up-to-date equipment. This is often more expensive but the clarity produced is excellent and the colors vibrant.

Customers need to be discerning when looking for printers like this. Going green is so popular that many businesses use it as a catch phrase without much substance behind it. Some printers go the whole way, using only 100% recycled paper, vegetable inks and so on while others allow the client to choose the extent to which they want to go green.

With digital printing, the ink is sealed to the surface of the paper with oil or wax. Inks used vary from printer to printer. Some use dry toner and others more liquid inks. Some are also far less toxic than others. Petroleum oils are being replaced by less harmful vegetable oils and many suppliers recycle oils. As the demand for less harmful ingredients increases, so quality improves and costs decrease.

With regard to paper used, there are various categories identifying which products meet expectations with regard to environmental responsibility. The use of alternative energy, such as wind generated electricity is one of these. Another is whether the paper is free of processed chlorine. Some printers use only 100% recycled paper while others use a variety of different papers, leaving it up to the customer to choose. Other printers use only paper made with electricity that is wind generated. Most printers use recycled paper to some extent thus reducing the use of virgin wood fibers.

Opting to use digital printing that is eco friendly is just one of the ways in which one can show commitment to protecting the environment. This does not mean one has to settle for inferior quality in any way as great strides have been made with this technology. The best printers with the latest equipment offer quality just as good as offset printers if not better.
