MEK-free ink (alcohol-based ink)

It does not make sense to cite a Japanese ordinance on the US inkjet site. Not necessary to remove but something to consider in the future.

The demand for ethanol ink has quadrupled over the past three years

  • Customer needs for alcohol-based ink has been on the increase as a solution to meet the requirements of the new Ordinance.
    At the same time, conventional alcohol-based inks have had issues with respect to their printing performance.

  • The demand for ethanol ink has quadrupled over the past three years

Problems with conventional alcohol-based ink

While alcohol-based inks feature easy handling and little or no odor, they also have issues with drying speed and maintenance.

    • Slow drying makes the ink unsuitable for high-speed production lines and use with plastic bottles and PP/PE films.
    • Low volatility makes the ink prone to thinning, which results in unstable text.

Advantages of the new ink MK-14

Conventional ethanol-based ink contains 80% to 90% ethanol. Ethanol has the previously mentioned issues due to its lower volatility compared to MEK. MK-14 is only 50% to 60% ethanol blended with a volatile glycolic solvent, which gives an enhanced quick-drying effect to the ink.
