Eco-solvent printing VS Solvent printing for Advertising

One question that most of my customers grapple with, is whether to go for a solvent or eco solvent print. To be able to make this choice, you first need to understand the difference between the two.
Eco-solvent printing
Eco solvent printing
Eco solvent inks have the colors suspended in a mild bio-degradable solvent. These inks have little or no odor. The machines using these inks typically print at very high resolutions. The ink heads have nozzles which can spray ink drops of size 10 picoliters or less. Obviously, with a smaller drop size one can achieve higher quality prints with very fine resolutions. Eco-solvent machines typically need specially coated media for printing upon.
The specialized ink chemistry and coated media does contribute to higher print costs. But this technology delivers beautiful photo realistic images and stunning print quality. Eco solvent prints would typically be used for indoor applications.

Solvent inks are much more aggressive and typically non bio degradable. These inks have a pungent odor and prolonged exposure to them can be harmful to humans. The stronger inks and more complex chemistry allows us to print on uncoated media or media with less coating. Also these inks are generally more resistant to water and sunlight. Solvent flex printing machines have a comparatively large drop size. The print heads on solvent machines spray ink drops of size 40 – 60 picoliters. While the larger drop size does result in slightly grainy image reproduction, it does not really matter. Because solvent prints are typically used for outdoor applications. If you are going to view a hoarding which is 40 feet distant from your car, waiting at the traffic signal, you won’t even notice the low resolution.
