Water-based inks dry and evaporate naturally, requiring no extra energy to do so.
Water-based Ink definition
Inks are used during the printing process to transfer your image onto the material using flexographic, lithographic, offset or digital methods.
All printing inks contain a pigment of colour, a binder (also called the base) which sticks the pigment to the surface, and a solvent to spread the ink over the desired area evenly. Additives are sometimes added to increase the ink’s durability.
Water-based inks have binder and solvents that are water-based.
Why you should use water-based inks
Water-based inks are used when printing directly onto the cardboard surface, rather than a separate piece of material that’s then laminated onto the cardboard. Water-based inks are transparent in touch - that is to say, the ink film cannot be felt, but rather deeply into the cardboard underneath.
Water-based inks emit no volatile organic compounds  (VOC’s) during the printing or drying process and therefore are safe to both workers and the surrounding atmosphere.
As there are no chemical additives, water-based inks are cheap and easy to produce. Water-based inks don’t require a heater to set, cure and dry, as they to do so at room temperature (approximately 18 degrees C  /64.6F).
Wastage is nothing more than dirty (non-contaminated) water that is fit to be released into the sewer for standard water-treatment processing. Some printing facilities also have in-house water treatment facilities to clear and reuse the water used in water-based inks.
Why shouldn’t use water-based inks
While water-based inks do cure naturally, they take longer to do so. This increases the turn-around time for an order, and depending on the facility, also holds up other orders.
While water-based inks do create water waste that can be treaded in council facilities, they do create wastewater, and a significant amount more than petroleum and solvent-based inks.
Packhelp and water-based inks
Packhelp’s products use water-based inks everywhere possible. Alternatives are used only when water-based inks cannot be used.
Water-based inks are used whenever the flexographic printing method is used.
All Packhelp’s water-based inks adhere to ISO 16758  .
