Most printers and copiers use one of two substances: toner, which is a dry powder, or ink, which is a liquid. However many people overlook the superior third option, Solid ink. Solid ink is the preferred medium for design professionals and I would argue that it is better for other businesses and household consumers as well. Here is why.
First off think about the reality of working with toner and ink. Anytime you change or refill a cartridge you are in danger of spilling some. Even if you are careful, cartridges often leak a little just from being handled. Toner is dry so it is not as likely to stain, but it is a fine powder so it gets everywhere. Ink is a liquid and when it gets on your hands (or shirt!) you will be seeing those marks for weeks. Not so with solid ink. Solid ink comes in solid sticks. These are heat-activated inside the printer, so unless they are heated up they do not stain. You can literally handle them with your bare hands and have no problems.
Second, think about cost. Early in their history solid ink was a specialty medium that was only used by large design firms. The result is that it has a reputation as being expensive. However, the price has come down and is now competitive with – sometimes much lower than – conventional ink and toner.
If I have a choice between something that is clean, professional and gives high quality results or something that is messy for the same price, I know which one I would choose. How about you?
