The development history of ink:

The earliest inks date back to China about 4,500 years ago. The inks used in ancient China were mainly made from a mixture of boiled vegetable dyes (such as Garcinia cambogia, etc.) and gums (such as animal bone glue). This ink has a thick black color and a long drying time.

In medieval Europe, the recipe for ink was improved. The ink began to use rubber resin as a binder to make it easier to adsorb to paper and dry faster. These inks are usually made from a mixture of rubber resin, metal salts, and alcohol.

At the beginning of the 20th century, more advanced ink formulations were invented. Water-soluble dyes are introduced into the ink, eliminating the need for volatile solvents such as alcohol. These inks have gradually replaced traditional inks, and with the advancement of digital technology, the emergence of digital printers and inkjet printers has brought about the demand for new inks.

Digital inks are used for high-quality color printing by dissolving fine particles or dyes in water or organic solvents. This ink is fast-drying, lightfast, water-resistant, and long-lasting.

The washing method of the ink is:

1. Cleansing oil + detergent: Slowly apply cleansing oil to your hands, rub for 2 minutes, then rub with detergent for 2 minutes, rinse with water, test the ink blot is slightly reduced, and it can be repeated many times to gradually fade.

3. Gasoline + shampoo:Pour gasoline on the palms of your hands, then squeeze some shampoo, rub them for 2 minutes at the same time, then wash, after testing, the ink has been reduced by 80%, but there is still an ink shadow, which can be repeated 2 times again to eliminate the ink stains.

4. Banana water + laundry detergent: Rub with banana water, add laundry detergent and rinse with water After testing, the ink is already very light, and then wash again, and the ink stain will gradually fade.

5. Rice soup + hand sanitizer: Apply ink stains with boiled rice soup, then wash with hand sanitizer, rinse with water, repeat 2-3 times, and the ink stains disappear after testing.

6. Wind oil essence + wet wipes: Apply the wind oil essence to the ink stain and scrub it for 2 minutes, wipe it off with a wet wipe, the ink stain will fade by half, and the ink stain will disappear completely after repeated scrubbing for 3-5 sides. Successful washing does not hurt hands.

7. Laundry detergent + toothpaste:If you are stained with ink, you can first use toothpaste to apply it to the ink-stained area, then scrub it with water (you don't need to rinse off the toothpaste, you only need to add some water to make it easier to scrub), then add laundry detergent and scrub again, and finally rinse it with water again.

8. Soap + milk: When the milk is warm, soak the ink-stained area in warm milk for 10 minutes and scrub it with your hands. If you can't scrub it off, consider applying soap and scrubbing it again to remove the ink.

9. Soap + alcohol:If you accidentally get ink on your hands, you can use alcohol and soap to clean it. Pour some medicinal alcohol on your hands, rub it in ink, scrub it with soap, and rinse it off with water.

The washing method of the ink can be selected according to the type of ink and the degree of stain, usually using soapy water or bleach.

Rinse the ink stain immediately with clean water for fresh ink stains to prevent them from penetrating deeper. Mix a small amount of neutral soap or detergent with warm water, gently apply to the ink stain, and rinse with clean water.

Soak the contaminated garment or cloth in milk for dry ink stains, then scrub gently and rinse with clean water. Carefully use a small amount of alcohol or light bleach (diluted bleach can be used) to gently wipe the ink stain and rinse with clean water.

Either method used, care should be taken to avoid further damage to clothing or surfaces. Additionally, it is best to test on an inconspicuous area before attempting any washing method to ensure that there is no irreversible damage to the material. If the ink stain is very stubborn or unmanageable, it is best to take the garment to a professional dry cleaner or consult a professional cleaning service.
