Koh-I-Noor produces three distinct formulations, each engineered for specific conditions.\u003c\/p\u003e\n\u003cp\u003eUniversal Drawing inks handle the broadest range of applications, technical pens, refillable plotting points, brush work on paper and film. Black and white deliver opaque coverage; all other colors remain transparent. Waterproof formula resists smudging once dry, essential for layered technical drawings where you'll overlay additional linework or annotation.\u003c\/p\u003e\n\u003cp\u003eRapidraw targets film work specifically. Fast-drying waterproof formula sets quickly to prevent smearing on non-absorbent surfaces, while remaining erasable on film for corrections. Short open pen time means you'll need to work steadily and clean nibs promptly, this ink suits experienced users who maintain consistent workflow and proper pen maintenance habits.\u003c\/p\u003e\n\u003cp\u003eUltradraw takes the opposite approach for paper applications. Slow-drying formula extends open pen time significantly, reducing clogs during pauses and making it forgiving for users still developing their technical pen technique. The longer working window accommodates interruptions without requiring immediate cleaning.\u003c\/p\u003e\n\u003cp\u003eAll three formulations come in 3\/4-ounce bottles with easy-fill spouts that simplify reservoir loading without mess. Choose based on your primary surface and how you work rather than defaulting to whatever's available.\u003c\/p\u003e","brand":"Koh-I-Noor","offers":[{"title":"universal drawing ink \/ green \/ 3\/4 oz.","offer_id":47976860385509,"sku":"33141","price":6.08,"currency_code":"USD","in_stock":false},{"title":"universal drawing ink \/ violet \/ 3\/4 oz.","offer_id":47976860418277,"sku":"35706","price":6.38,"currency_code":"USD","in_stock":false},{"title":"universal drawing ink \/ black \/ 8 oz.","offer_id":47976860451045,"sku":"39784","price":34.09,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ black \/ 3\/4 oz.","offer_id":47976860483813,"sku":"47656","price":6.91,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ red \/ 3\/4 oz.","offer_id":47976860516581,"sku":"51110","price":6.38,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ white \/ 3\/4 oz.","offer_id":47976860549349,"sku":"63044","price":7.1,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ yellow \/ 3\/4 oz.","offer_id":47976860582117,"sku":"65472","price":6.38,"currency_code":"USD","in_stock":true},{"title":"ultradraw ink \/ black \/ 3\/4 oz.","offer_id":47976860614885,"sku":"69515","price":7.28,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ brown \/ 3\/4 oz.","offer_id":47976860647653,"sku":"70351","price":6.38,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ carmine \/ 3\/4 oz.","offer_id":47976860680421,"sku":"78181","price":6.08,"currency_code":"USD","in_stock":false},{"title":"rapidraw ink \/ black \/ 3\/4 oz.","offer_id":47976860713189,"sku":"79544","price":7.28,"currency_code":"USD","in_stock":true},{"title":"universal drawing ink \/ blue \/ 3\/4 oz.","offer_id":47976860745957,"sku":"79742","price":6.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s35706.jpg?v=1770317769"},{"product_id":"higgins-black-magic-waterproof-ink","title":"Black Magic Waterproof Ink","description":"\u003cp\u003eDrafting film demands different properties than paper, and standard inks fail the test. Black Magic grips polyester surfaces without peeling or flaking, maintaining crisp edges through repeated handling and reproduction. The intense black formula delivers consistent line density whether you're working on vellum, prepared acetate, or automatic drafting equipment, ensuring clean copies with strong contrast every time.\u003c\/p\u003e\n\u003cp\u003eWaterproof formulation sets permanently once dry, resisting smudging during revisions or when overlaying additional sheets. Lines stay sharp without the chipping that compromises technical drawings, while the ink's chemistry bonds reliably to non-porous surfaces that reject ordinary formulas. Architects and technical illustrators working across multiple substrate types keep this ink on hand because it eliminates the guesswork, one bottle handles everything from traditional paper to modern drafting film with the same dependable performance. Pour it into technical pens or use it straight from the bottle for ruling and lettering work that needs to survive the rigors of professional reproduction.\u003c\/p\u003e","brand":"Higgins","offers":[{"title":"1 oz.","offer_id":48102359433445,"sku":"28193","price":5.93,"currency_code":"USD","in_stock":true}]}],"url":"https:\/\/www.texasart.com\/collections\/drawing-and-illustration-ink-technical-inks.oembed","provider":"Texas Art Supply","version":"1.0","type":"link"}
