{"product_id":"sea-white-block-printing-ink","title":"Seawhite Block Printing Ink — 300ml","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSeawhite's own block printing ink — made by a company that has been supplying the UK art education and printmaking market for over fifty years, and knows exactly what a good relief printing ink needs to do. Viscous, slow-drying, and generously sized at 300ml, it is a practical, reliable ink for lino, wood, and foam block printing at any level from introductory classroom work through to more considered studio printmaking.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe viscosity is the defining quality. A good relief printing ink needs to be thick enough to sit on the surface of the block without flooding into the cut recesses, thin enough to roll out evenly on a glass or acrylic inking slab, and sticky enough to transfer cleanly from block to paper under pressure. Seawhite's formulation hits that balance well — it rolls out smoothly, covers the block evenly, and transfers with a clean, consistent impression. The extended working time is a significant practical advantage, particularly in teaching environments where ink on a slab needs to remain workable across a full session without drying out prematurely.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe ink is water-based and non-toxic, making it safe and practical for use in schools, studios, and home printmaking. Equipment cleans up easily with water. All nine colours are fully intermixable, giving the freedom to mix custom shades on the slab from a small selection of tubes. Drying time is approximately 30 minutes to the touch under normal conditions, though this varies with temperature, humidity, and the thickness of the ink layer applied.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWe stock nine colours: Black, White, Brilliant Red, Orange, Brilliant Yellow, Brilliant Green, Brilliant Blue, Purple, and Burnt Sienna — a well-considered palette covering the primary and secondary colours, a warm earth tone, and both black and white for tinting, shading, and overprinting.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat surfaces can Seawhite Block Printing Ink be used on?\u003c\/strong\u003e It is designed for lino, wood, and foam cut relief printing blocks. It is suitable for printing onto paper and card. For printing onto fabric, a dedicated fabric printing ink is more appropriate as standard block printing inks are not formulated to withstand washing.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow is it applied to the block?\u003c\/strong\u003e Squeeze a small amount of ink onto a flat inking slab — glass or acrylic works well — and roll out evenly using a rubber brayer until the ink covers the roller in a thin, even layer. Roll the ink onto the block surface in multiple directions to ensure even coverage, then press the block firmly and evenly onto the paper or pull the paper over the block and apply pressure by hand or with a baren.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow long does it take to dry?\u003c\/strong\u003e Approximately 30 minutes to the touch under normal conditions. Drying time varies with temperature, humidity, and the thickness of the ink layer — cooler, more humid conditions will slow drying, warmer conditions will speed it up.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCan the colours be mixed together?\u003c\/strong\u003e Yes — all nine colours are fully intermixable. Mix directly on the inking slab to create custom shades before rolling out and applying to the block.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow do you clean up?\u003c\/strong\u003e All equipment — roller, slab, block, and hands — cleans up easily with water. Clean promptly after use before the ink has had time to dry on equipment.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eIs it suitable for use with children?\u003c\/strong\u003e Yes — the ink is non-toxic and water-based, making it suitable for supervised use with children in classroom and workshop settings.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Seawhite","offers":[{"title":"Black 20217","offer_id":31734994337844,"sku":"PTPIB","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"White 20217","offer_id":31734994370612,"sku":"PTPIW","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"brilliant Red","offer_id":31734994403380,"sku":"PTPIBR","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Orange 191125","offer_id":31734994436148,"sku":"PTPIO","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Brilliant Yellow 191125","offer_id":31734994468916,"sku":"PTPIBY","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Brilliant Green 20219","offer_id":31734994501684,"sku":"PTPIBG","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Brilliant Blue 20217","offer_id":31734994534452,"sku":"PTPIBB","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Purple 20217","offer_id":31734994567220,"sku":"PTPIP","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Burnt Sienna 20218","offer_id":31734994599988,"sku":"PTPIBS","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"SILVER","offer_id":57502858674551,"sku":"PTPIS","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"GOLD","offer_id":57502882070903,"sku":"PTPIG","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Magenta PTPIM","offer_id":57504294437239,"sku":"PTPIM","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Prussian Blue","offer_id":57504295485815,"sku":"PTPIPB","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"Lemon","offer_id":57504313213303,"sku":"PTPIL","price":6.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0076\/2288\/5428\/products\/6c4ce893-c038-40a3-8db0-a9d100ca4574_1000x1000_0485d5f3-2e47-45cc-9641-4c2f82495303.jpg?v=1769676775","url":"https:\/\/craftandcanvas.live\/products\/sea-white-block-printing-ink","provider":"Craft and Canvas","version":"1.0","type":"link"}
