What is a key advantage of modern printing methods?

A significant advantage of modern printing methods is that printing inks are becoming 'greener.' This reflects the industry’s shift towards environmentally friendly practices. Many modern inks are made from sustainable resources, such as soy or vegetable oils, which not only reduce the reliance on petroleum-based components but also lower the environmental impact of printing processes.

The trend towards 'greener' inks aligns with a broader societal push for sustainability by minimizing harmful emissions and waste associated with traditional inks. As consumers and companies alike become more environmentally conscious, the availability and use of these eco-friendly inks can enhance the appeal of printed materials across various industries, thereby promoting responsible printing practices.

The other answer choices reflect negative aspects or misrepresentations that do not align with the positive evolution in the printing industry. For instance, non-recyclable inks contradict the movement towards sustainability, while accuracy in printing has improved significantly with modern technology, and the costs are often justifiable when weighed against the benefits of enhanced efficiency and quality.
