Letterpress ink8/6/2023 Soya bean oils have been used for some time as an alternative for linseed oil, as they share similar characteristics. With the advent of petroleum refining, mineral distillates have reduced the role of linseed oils in inks, but most conventional inks for letterpress use have at least some linseed or other vegetable oil in the vehicle component. Linseed oil, the expressed oil from the flax seed has had the longest history in this role. Traditionally vegetable oils have been used as the vehicle in inks. The vehicle of an ink is the component which allows the ink to flow, and allows ink to spread and transfer from roller to roller and from roller to plate (in the case of letterpress, whatever raised surface is used as an image carrier).

Keep in mind: don’t mix rubber-base inks together with oil based inks (note that metallics are always oil-based). Pros: strong general ink (it’s what we use in our shop!) matte finish slow drying so you can leave it on the press for several hours or overnight will not skin in the can ideal for matte papers colors are strong and vibrant.Ĭons: not ideal for metallic or coated papers (takes longer to dry) large solids with heavy ink coverage can take days or weeks to dry slow drying of inks when overprinting (layering multiple inks on top of each other) colors may not be as loud or bright as other oil-based inks. 20-30% vegetable oil (including soy and linseed).We need a three or four digit number for each ink color.īreak down of components (varies depending on color) It is best if you are looking at a Pantone Uncoated Formula Guide for the most accurate color chip.
