Derivan Screen Ink

is a totally water-based silk screen printing ink. It has been formulated as a safe, non-toxic ink for fabric, and can be used in the classroom or at home safely without the worry of being exposed to harmful solvents such as white spirits, turps or thinners. Derivan Screen Ink washes up in water (before it is heat set) but has excellent rub resistance and lightfastness once heat set.

Derivan Block Ink

has the perfect consistency for lino or wood block printing and transfers and will allow sharp, accurate prints onto paper. It is non-toxic and easy to clean up while still giving the feel of a profes-sional grade oil-based printing ink. Derivan Block Ink

has been formulated for lino and wood block printing on paper. Derivan Block Ink will remain open on the block for some time but once printed will dry quickly. If a longer open time is required, mix Derivan Drying Retarder to slow the drying time
