Comparison of Water-based Pigment Ink, Water-based Dye Ink and Weak Solvent Ink

Mar 31 , 2020

What is the difference between water-based pigment ink, water-based dye ink and weak solvent ink? How should we make the right choice? Water Based Eco Solvent Ink Manufacturer is detailed here.


Characteristics of water-based pigment ink: Water-based ink is 100% soluble in water and can be diluted by purified water. At present, desktop inkjet printers and indoor photo printers on the market use this type of ink-water-based ink, and the paper materials printed with this ink must be special and coated, otherwise they will be printed out.


Water-based pigment ink is water based on nano-pigment particles as its color base. Its ultra-fine pigment particles are suspended in an aqueous solution and formulated with a professional formula. The image point is powdery ink. Of course, this is just an image and it is not accurate enough. To be more precise, it grinds the solid pigment into very fine particles and dissolves it in a special water solvent. It is a suspension solution or semi-solution, which has the same properties as the pigments of our printing and dyeing clothes. Water-based pigment ink is characterized by strong color saturation. Because the resin is coated with pigment particles, it is waterproof and scratch-resistant. The best feature is strong color fastness and extremely difficult to fade. It can be said that it will never fade for 100 years. Used for artwork reproduction. The quick-drying, scratch resistance, and light resistance of general water-based pigment inks are difficult to meet standards.


Contrary to the principle of dye ink penetrating into the medium to form color, it develops color by attaching color materials to the surface of the medium (such as copy paper or printing paper). Therefore, it has the advantage of printing with pigment ink, even if it is printed on ordinary paper, it will not bleed, and because the pigment itself is waterproof, it is not easy to be decomposed by ultraviolet rays, so it has strong water resistance, light resistance, and printed things. Maintains no visible signs of discoloration for more than a year even when used outdoors.


Next, introduce the water-based dye inks and understand the characteristics of water-based dye inks:

Dye ink is a molecular-level fully-dissolved ink. This ink is a complete compound solution, and the probability of clogging the ink head is very small. It is easy to be absorbed by the material after printing, and has bright colors and low cost. The advantage is that the color is bright, the layers are clear, and the price is lower than the pigment-based ink, so it is the first choice for printing pictures and making inkjet business cards. Water Based Dye Ink For Epson is a dye ink close to the market.

Finally, talk about Mild Solvent Ink and learn about the characteristics of weak solvent inks. Compared with ordinary solvent-based inks, the weakest solvent inks have the biggest environmental friendliness, which is mainly reflected in the reduction of volatile VOCs and no longer using many toxic organic solvents. They are no longer used in the production workshop of weak solvent inkjet printers. Ventilation is required. Odorless, environmentally friendly, weak solvent inks, while maintaining the advantages of high-precision screens made by water-based inks, also overcome the disadvantages of water-based inks that are harsh on the substrate and the screens cannot be applied outdoors. Therefore, weak solvent inks are between water-based and solvent-based inks, taking into account the advantages of both.
