Our Classmates Block Printing Ink is a high-quality water-based, non-permanent lino printing ink. This ink has been formulated using high quality specialist raw materials to give enhanced tack and transfer for superior printability and performance. The Ink's drying speed has also been optimised to give a good balance of 'on tray working time' and drying time at typical ambient conditions. Classmates Block Printing Inks are all intermixable and quicker drying than oil-based inks. Even when dry they are water re-soluble, making them very easy to use and equipment simple to clean with soap and water. Non-permanent. Water-based. Equipment can be very easily cleaned. Packaged in transparent tubes with flow control caps, making them very convenient to use. Wheat and gluten free. Available in Metallics, Fluorescent or Pearlescent Colour packs.
