Jacquard Professional Screen Printing Inks have good body and screen beautifully with excellent resolution. With a slightly more noticeable, hand they are especially well suited to commercial applications. These inks were designed for all surfaces and are permanent on most. They will not wrinkle paper when screening art prints. Choose from a nice assortment of regular, metallic, opaque and "process" colors. Extended Open Time: These inks break new ground with a greatly extended open time unmatched by any other ink. This gives you the flexibility to work with more colors and do bigger runs without the ink drying in the screens. Permanence: Archival & lightfast these inks are permanent on most non-porous surfaces including: fabric, paper, plastic, vinyl, leather, metal, & more! Fabrics must be heatset for permanence and durability, or you can add Jacquard AirFix to the paint before screening and cure for a few days. Once set, the inks are fully washable and dry-cleanable on all natural & synthetic fabrics. Since these stick to almost anything, they are great for linoleum block printing as well. No need to rough up the linoleum. Washability: Fully washable and dry-cleanable on all natural & synthetic fabrics when properly heat fixed. Waterbased: No smelly solvents and cleanup is easy with just soap & water. Process colors: Jacquard has created these colors for those who screen print using what's known as "4 Color Process Screen Printing" or "CMYK Printing". Using this process the four colors (cyan, magenta, yellow and black) can reproduce most of the entire spectrum of colors. This particular style of printing takes special care and is much trickier than simple screen printing. The Process colors can be used in the the same ways as the others but were created specifically with CMYK printers in mind.
