Bulk (1,000 ml) Premium Black Oil-Based Refill Ink for Pre-Inked Stamps & Dot Matrix Printers

Say hello to the 1000 ml (1 L) Oil-Based Stamp Ink - the ideal option for those in need of refilling their pre-inked stamps, felt pads, and dot matrix printers. With its bulk packaging, it offers an economical solution for those seeking to save money on their purchases. This ink is identical to the 20 ml retail packaged ink (OS-STAMPINK-O-BK20), but with 50 times more volume. It's the perfect choice for industrial or corporate users.

This non-toxic oil-based ink is safe for both your skin and the environment, with low odor and waterproof after drying. Its outdoor-grade weatherproof and none-fading properties are thanks to its sturdy pigment polymer resin, which won't fade under direct sunlight. Application is simple - just add four to six drops of ink to a dried stamp pad. This ink is compatible with most stamps, including popular brands like Ideal, MaxStamp, Maxum, Plus 2000, ExcelMark, Cosco, and Trodat. If your stamp is labeled "non-refillable," check out the YouTube video for instructions. Refilling dot matrix printers is also possible with this ink - refer to Keith's blog for guidance.

This Oil-Based Stamp Ink is available in black and offers great value, as you can refill your stamps and felt pads for a fraction of the cost of buying new ones. Whether you're using it for stamp foam ink pads, felt pads, pre-inked stamps, or oil-based print ribbons for equipment like dot matrix printers, you can expect a high-quality, durable, and permanent result. Don't over-ink the pad to ensure the best results.

General Instruction

The oil-based ink will be absorbed into either rubber or sponges. The process is a lot slower than water-based ink. However, the ink is designed to last a long time in the open air, so be patient. You will either find an absorbent rubber or refill sponge in your equipment. If you work on a typewriter ribbon that doesn't have those, then the ink needs to be absorbed by the whole ribbon. If your stamp doesn't have a refill sponge, like in the video below, you can drill a hole and create a cavity to fill the ink and let the ink be absorbed over time.

Refill Instruction for Dot Matrix Printers

How to Refill a Star Micronics NX-1020 9-pin dot matrix printer - by Keith 

I ordered the ink and applied it to the dot matrix ink cartridge, and it worked great. It was less messy than expected, and while I used WAY TOO MUCH, and subsequently needed to cycle the whole cartridge a few times via some paper towels. There's a reinking wheel (which appears to be a spinning sponge, essentially), which wasn't immediately absorbing the ink. So I applied some directly to the ribbon itself. In retrospect, I did try applying through the top of the sponge instead of the side. The ink transfer to the ribbon appears to be done.

Please see the image.

The ideal approach seems to remove the reinking sponge (large black round center object), which is simply sitting there(it doesn't snap into place or anything), apply ink to THE SIDES of the sponge, and let that absorb as much as possible. Reinking the ribbon is also necessary, especially for older, more dried-out ribbons. Given the way it works, the reinking sponge appears to transfer to the small black gear. Then contacts the ribbon itself directly. I think this process is going to be slow and take a while to reink the ribbon. Therefore, also applying ink directly to the ribbon should speed the process. The ink should be applied sparingly and then using a paper towel (or other absorbent cloth) to contact the exposed ribbon. You should remove any excess ink by rotating (counter-clockwise) until a complete circle of ribbon has been cycled. Initial printouts were messy. After about a dozen pages, the quality improves dramatically. I hope this helps.
