Benefits Of Digital Printing That Is Eco Friendly

By Michelle Hall


Consumer patterns are shaped by many things that range from the quality of a product to the price to the values of the manufacturer and so on. Recent times have seen increased demand for products manufactured in a manner which conserves the environment and a drop for those which do not. The digital printing industry is among those greatly affected. Digital printing that is eco friendly can be achieved in a number of ways.

Ink is among the most important inputs of this process. The type of ink used has traditionally been derived from fossil fuels meaning it has possessed a potential harmful effect to the environment. When the ink is broken down in the environment, it results in the production of volatile organic compounds, VOCs, which in turn react with environmental gases to form a low lying ozone layer. The ozone is harmful because it contributes to smog formation.

Printing paper is another important input in the process. Continued use of paper has put trees and by extension, important ecosystems, at risk. The two options are virgin and recycled paper. Whereas the former is obtained directly from trees, recycled paper makes use of paper used previously. There is no doubt that an environmental conscious business will opt for the recycled paper option. Apart from conservation, recycled paper is also cheaper to process.

The other raw materials can similarly be recycled. Ink, water and aluminum plates are among the most commonly reused materials. Water, in particular is quite easy to re-use. If the firm is operating efficiently, it is estimated that up to 60% of the water utilized in the first cycle can easily be reused in subsequent cycles. This goes a long way into not only conserving the environment but also cutting down on the associated costs.

Make an effort to reduce on your energy consumption. This may require you to conduct regular evaluation to determine whether your printers are functioning optimally. The printers should give you the highest output possible for a single kilowatt of electricity consumed. Another measure which needs to be undertaken is a shift from total reliance on fossil based fuels. Both solar and wind energy are now being considered effective alternatives.

Similar measures that are meant to enhance sustainability are also being considered when it comes to the printing of fabrics. One of the biggest changes taking place is the elimination of urea based methods in the pre-treatment. Urea releases carbon dioxide as a byproduct and this pollutes the environment directly. There is a special foam that can be easily impregnated into a fabric and achieve the desired results.

Digital engraving is another useful development which is helping achieve sustainability as relates to fabric printing. It is an option that is being adopted in place of traditional techniques that use wax or ink. The older alternatives not only require a lot of water during processing but also take quite long. Digital engraving uses laser to create prints on fabrics.

Every business has a responsibility towards the environment. Processes used should promote environmental sustainability and the same should be applied to the entire supply chain. Sustainable solutions are not only beneficial to the environment but also helps the business by reducing the operating costs in the long term. The consumer may also benefit through fair priced products.
