Comparison Of Several Commonly Used Inks

What is the difference between water-based pigment ink, water-based dye ink and weak solvent ink? How should we make the right choice? Here the Resistant Sublimation Ink Supplier will come to share with you.


Characteristics of water-based pigment inks: Water-based inks are 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 large type of ink-water-based ink, and the paper materials printed with this ink must be special, coated, or printed. Can get rid of ink, or pile ink, or difficult to dry.


Pigment Ink is 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 colors, 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. The disadvantage is that most pigment inks leave color materials on the surface, so even if you print on flat paper such as glossy paper, you can't print glossy images. This is why pigment inks are usually used to print Nothing is shiny because of it. In addition, pigment inks are more expensive to manufacture, so they are more expensive than dye inks, with price differences as high as two to four times.

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


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 disadvantage is that it is not waterproof, and because the dye molecules decompose quickly under UV radiation, it will cause obvious discoloration within one month of outdoor UV. The advantage is that the color is bright, the layers are clear, and the price is lower than the pigment ink. Therefore, it is the first choice for printing pictures and making inkjet business cards.


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 greatest environmental friendliness, which is mainly reflected in the reduction of volatile VOCs and no longer using many toxic organic solvents. Ventilation is required. The odorless, environmentally friendly, weak solvent ink maintains the advantages of high precision of water-based ink production, while overcoming the disadvantages of water-based inks on the substrate and the production of images that cannot be applied outdoors. Therefore, weak solvent inks are between water-based and solvent-based inks, taking into account the advantages of both.
