Pigment Based Ink
Pigment-based inks contain organic molecules encapsulated in a synthetic resin before being placed in suspension in a liquid. Pigment inks molecules are more abundant and better resist external forces like light and ozone moisture compared to dye inks. They are made up of tiny, encapsulated particles that sit on top of the substrate. Pigment is naturally resistant to water.
When printing with dye ink, the molecules distribute uniformly on the label. Dyes are sensitive to light and moisture, and so dye-based inks should sometimes be avoided based on the job. The durability of these prints can be reduced in more rugged usage. Dye inks are water-soluble, meaning that they dissolve easily in water. This means that in the event you have an image printed with dye ink and it becomes wet than the ink will begin to dissolve, and the print will be ruined.
Which is best for me?
Pigment ink is found in top-end label printers, capable of high-quality output onto a variety of media. It is also durable since pigment inks do not smudge and are excellent for labels that will be on display.
Dye inks are more economical to produce than pigment ink, so you will find that they are the most common inks used. You’re going to get great color vibrancy as dye inks tend to provide brighter and more vivid colors than pigment inks — especially effective for vibrant portraiture or landscape pictures. Dye also works with a range of papers with the very best results coming on glossy labels.
Ultimately, your choice of which print technology is determined by both budget and intended use.
