We offer only inks that have been specially formulated for specific printer types for good colour matching. We do not supply an inferior generic or so called " universal " product. Tried cheap and nasty inks in the past??... Try Jettmanx!

Our support for users of inkjet printers refilling their own cartridges now extends to more than 80 premium inks formulated for use specifically in a single type of inkjet printer cartridge or close compatible. These are available in quantities of 60ml, 250ml, 500ml and 1ltr sizes. For the low volume user, or simply to get started, we offer more than 40 starter kits with full step by step instructions for successful refilling, again with dedicated products for specific printer types. Click on these links to see examples of our instructions for refilling.

Premium inks v "universal" inks

We do not offer so-called "universal" inks for the simple reason that there is no such thing. These generic inks are marketed as being suitable for any printer, promising outstanding results and often claiming to be the best refills available. They are far from that and in fact, they put more users off refilling than anything else. There are a variety of reasons why a universal ink is just not possible. Major differences exist between inks for various printers even within the ranges of individual manufacturers. Variables include composition, viscosity, surface tension, conductivity, drying time and absorbency. Importantly, the refill ink must be chemically compatible with the original ink, and since all oem inks vary widely, it is impractical to produce a truly universal inkjet ink. The empty cartridge into which you refill will contain traces of the original ink as will the printhead. Incompatibility between the original ink and the refill can under certain conditions cause crystallisation when the two come into contact, leading to interruption in the flow of ink or blockages. Moreover, different printer manufacturers produce machines which operate to completely different principles. The main two genres are thermal as used by Canon and Hewlett Packard (where a minute bubble of ink is heated by electrical resistance and then fired through the jets) and Epson’s piezoelectric (where an inorganic crystal changes structure and volume thereby activating the ink). Unfortunately for "universal" inks, no single formula can accommodate features for long-term, troublefree operation of the various types. Other factors have to be considered. Inks must be compatible physically and chemically with the sponges or other containment systems used by the cartridge manufacturers. If this is not taken into account, plastics and sponges may be attacked by the ink. Nozzle dimensions of the printheads of various printers also vary widely requiring the appropriate surface tension and viscosity to obtain the correct dot size. Last but not least, printer models work at different speeds requiring just the right drying time in each case. Too slow, the next sheet will fall on the previous sheet whilst the ink is still wet. Too fast and it will dry on the print head and never get as far as the paper.

We hope that the foregoing will give an appreciation of why our range consists of so many bespoke inks and why "universal" inks however cheap and seemingly uncomplicated, are not an option.
