Ink eradicators

USE In cleansing compds, oil-well drilling, water treatment, cheese emulsification, as general sequestering agent, to remove rust stains, as ingredient of one-fluid ink eradicators, in electrodeposition ol metals. 

Ferric tannate is the major ingredient of black ink, and acid destroys it. That s how old-fashioned ink eradicators worked — you sprinkled a little acid on your error and hoped it would destroy the ink before it destroyed the paper. Careful blotting was clearly necessary. 

The chemistry of ink eradicators, discussed in the answer to the previous question, comes into play here as well. Acids — such... 

Safety inks Printing inks which will change color or bleed when ink eradicator or water is applied to prints. Also inks which will erase easily. Usually, mixtures of a drying-oil ink with an aqueous solution of a water-soluble color. 

The development of xerography has led to new technologies that some predict will eventually eradicate traditional offset printing machines. These new machines, which print in full CMYK color (printing terminology for cyan, magenta, yellow, and black), such as Xeikon, use xerography but provide nearly the quality of traditional ink prints. 

Eradication of the need to pretreat before ink jet printing. This research is principally focused around those pigment dyestuffs that aheady skip the pretreatment stage and is related to research for a universal ink that can be used on aU liber types. A universally appUcable ink jet print process could not only offer savings for both business enterprise and the environment, but present game-changing conditions to the established textile print industry. 

Water based flexographic inks usually contain between 5-20% of organic solvents. Although they are harmful, they cannot easily be eradicated because they help to reduce the drying time of the ink once it is applied on a surface (paper, cardboard, plastic, etc.).
