Bottle, Black is the ultimate Black India ink. Extremely versatile waterproof drawing ink. Ultra-fast drying time. Use on paper, vellum, tracing paper and drafting film. Made in USA. Review: Dense, deep black lines, but needs drying time - I use Koh-i-noor rapidographs for technical drawing and lettering, but only occasionally. Many years ago, only the original rapidograph ink was available and while it made the best deep black lines, the ink dried quickly. If you did not use the pen for a week, there was a 50/50 chance it would be clogged by then. The Ultradraw is just as dark and free flowing as the rapidraw ink, but it takes a lot longer to dry. And this is likely why it does not clog as quickly. To me it is worth the tradeoff. Just be sure not to touch the wet ink for 30 seconds and you will be fine. But if you have to use a T-square and templates, this might delay completion of your project since ink might smear. You need to factor drying time. One last thing, this ink does not draw well on plasticized surfaces. The rapidraw is much better for that. Review: Photo does not match description! - Be very careful--the photo listed as of 8/24/20 does not match the description. The photo is Rapidraw but the description is for Ultradraw. I have also received Universal when ordering Ultradraw. They are three very different products. This review is for Ultradraw, which is a pigment-based ink specifically designed for technical pens. It is waterproof, lightfast and archival quality. The Universal ink, which comes in an almost identical container, is dye-based and not lightfast. I use Ultradraw in most of my technical pens including Koh-I-Noor Rapidographs, K&E Leroy, Alvin Reform, and Faber-Castell. It works very well in each of these brands when used on good quality paper. I do most of my work with the smaller nib sizes--.13mm up to .35mm--and this ink flows very consistently.. I have also had good success using Ultradraw in Rotring Isograph pens as well as Staedtler Mars 700 and Marsmatic pens. The only reason I don't currently use Ultradraw in these pens is because I have a good supply of both Rotring and Staedtler ink. When this supply is exhausted II'll switch these pens over to Ultradraw as well. I don't necessarily prefer the Ultradraw to Rotring Isograph Ink or Staedtler Marsmatic 745R ink, but I have found it to be just as good and less expensive--especially when purchasing the much larger 250 ml/8 oz bottles. I frequently put down watercolor washes over the top of drawings and have never had this ink run or bleed as long as it's given time to dry. I'm not sure what the manufacturer recommends but I frequently put down a wash within 30 minutes of having finished a drawing. However if it's a drawing I've invested a lot of time in I'll let the ink dry overnight. Clogging has not been a problem as long as I use good paper and properly maintain my pens. Although waterproof when dry, this ink cleans up easily with water. I typically partially disassemble and rinse the nib each time I refill the cartridge unless I will be using the pen heavily for several days in which case I'll clean the nib less frequently. Be very careful not to overfill the ink cartridge. If it's too full--depending on the brand of pen--when you reattach the cartridge to the base of the nib assembly it will force ink up through the base into the breather gap cut into the nib threads. You'll know if you've done this because ink will be forced out of the threads at the tip of the pen and you'll likely have it all over your fingers and possibly all over anything else you've touched. Blocking the breather gap prevents ink from flowing properly--regardless of the brand of ink. To fix the problem remove the ink cartridge, partially disassemble the nib assembly (but not the nib itself) and rinse and dry the nib threads as well as the matching threads in the base. Reassemble and make sure you only fill the cartridge to within 3/8" of the top. When not in use I store my pens nib-up. I've found that even so the pens almost always start immediately when I use them next. If they do hesitate I use a Koh-I-Noor bulb syringe to draw a tiny bit of ink out of the nib, which I've found works much better than tapping or shaking. Koh-I-Noor Ultradraw is my go-to ink for pen & ink drawings and for use under watercolors. While I can't say it's better than Rotring or Staedtler technical pen ink I've found it to be just as good and usually less expensive. I also highly recommend this Koh-I-Noor Ultradraw over Koh-I-Noor Universal ink. The Ultradraw is archival and very opaque, while the Universal is dye-based, less opaque, and not lightfast. ## Features - The ultimate Black India ink - Extremely versatile waterproof drawing ink - Slow drying ink for long open pen time. - Use on paper - Made in USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0026HZ3DO | | Best Sellers Rank | #51,680 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #77 in Drawing Inks | | Brand | Koh-I-Noor | | Brand Name | Koh-I-Noor | | Container Type | Bottle | | Customer Reviews | 4.6 out of 5 stars 552 Reviews | | Global Trade Identification Number | 00014173276353 | | Included Components | Bottle of Ink | | Ink Color | Black | | Item Type Name | Ink | | Item Volume | 21 ml | | Item Weight | 22.68 g | | Manufacturer | Chartpak Inc. | | Manufacturer Part Number | 3085 | | Model Number | 3085.BLA | | Number of Items | 1 | | Package Information | Bottle | | Paint Type | Pigment | | UPC | 014173276353 | | Unit Count | 1 Count | | Volume | 21 ml | | Warranty Description | No Warranty | ## Product Details - **Brand:** Koh-I-Noor - **Global Trade Identification Number:** 00014173276353 - **Item Volume:** 21 Milliliters - **Package Information:** Bottle - **Paint Type:** Pigment ## Images ![Koh-I-Noor Ultradraw Pigment-Based Ink, 0.75 Ounce Bottle, Black (3085F.BLA) - Image 1](https://m.media-amazon.com/images/I/71686XeOS4S.jpg) ![Koh-I-Noor Ultradraw Pigment-Based Ink, 0.75 Ounce Bottle, Black (3085F.BLA) - Image 2](https://m.media-amazon.com/images/I/71UGhfuT-7L.jpg) ![Koh-I-Noor Ultradraw Pigment-Based Ink, 0.75 Ounce Bottle, Black (3085F.BLA) - Image 3](https://m.media-amazon.com/images/I/71u5XgghkpL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Has anyone had any experience using this ink in a fountain pen** A: I am using this ink in a calligraphic fountain pen. When pen is not in use, I put the cap on. I clean the pen throughly every week when in use. When i am not going to use, i clean it and keep it empty. **Q: Does this work with Alcohol Markers?** A: No **Q: The photo of the product shows rapidraw ink #3084-f while the description says ultradraw ink #3085-f. will i receive #3085-f (ultradraw) if i order?** A: The title says Ultradraw #3085. The picture shows Rapidraw #3084. I was sent Universal #3080. I think they are just cleaning out the shelf stock and if it is black looking in a bottle they shipit. I will not order from this vendor in the future. **Q: Hi! can this be used in a Staedtler marsmatic? thanks** A: Yes this ink is made specifically for technical pens. like the Staedtler Mars Matic 700 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dense, deep black lines, but needs drying time *by J***L on April 17, 2025* I use Koh-i-noor rapidographs for technical drawing and lettering, but only occasionally.
