Printing International provides pad printing ink that is specially designed for the pad printing process. We have a pad printing ink suitable for all kinds of applications, such as medical, cosmetic, automotive, promotional, apparel, and electronic objects, as well as appliances, sports equipment and toys. Solvent ink is largely used as a common pad printing ink.
Printing International has built a large library of existing colours, which stores existing matches and ink formulations for all of our pad printing ink ranges. If the colour requested is not an existing colour, our ink technicians will use highly accurate calibrated measurement tools and experience to define the colour and match the target. Multiple technologies from human eye to spectrophotometers will be used to match pad printing inks to nearly any shade on any printable substrate.
There are different types of ink for pad printing. Standard solvent-based inks are the most common and come in two variants; one and two component ink. Then there is also the UV, glass and ceramic inks.
We offer inks for all kinds of industries, but mainly focus on inks for:
Our inks conform to the most common guidelines worldwide such as: EuPIA, GADSL, RoHS, EN 71/3, REACH, USP CLASS VI, cGMP, GAMP5, FDA.
There is a technical data sheet for each ink, stating what it is suitable for. This sheet also states whether or not pre-treatment or post-treatment is necessary. It can also be deduced from this that several inks are suitable for some products.
The most important selection criteria for an ink are the following:
These inks consist of the following components: resins, pigments and thinners. The resin, also called binder, is the most important component, together with the special additives, the binder is responsible for the mechanical properties of the ink film (adhesion, abrasion resistance, scratch resistance and drying). The pigments are the dyes that are mixed in the resin. The thinner (see additives) ensures that the viscosity of the resins and pigments is adjusted to the desired printing properties of the pad printing ink. After printing and curing, only a very thin ink film remains on the product.
