With the improvement of environmental awareness and the strengthening of environmental regulations, the application of water-based ink in the printing industry is becoming more and more widespread. Water-based ink is an ink system formed by using water or a mixture of water and a small amount of organic solvents as a carrier, dissolving water-soluble dyes or dispersing organic pigments uniformly in it, which has ultra-low VOCs (Volatile Organic Compounds) emission, no solvent residue, and meets the requirements of modern environmental protection, and is a kind of environmentally friendly ink. In this, water-based ink can be divided into pigment ink and dye ink, which are widely used in packaging printing, advertising printing, book publishing, commercial printing and many other fields.
In reality, with regard to pigment ink and dye ink, friends who do not understand the difference between the two often wonder, can pigment ink and dye ink be mixed? Mostly considering the cost factor, because dye ink is much cheaper than pigment ink, the price difference is usually up to two or even three or four times. For example, if you have half a bottle of pigment ink left, and you don't want to spend too much to buy another bottle, then why don't you buy the cheaper dye ink to mix it?？
Here, I recommend not mixing these two inks.
Dye ink is a molecular-level fully dissolved ink, through the penetration of paper fibers and stain them to achieve the effect of writing or printing, but the printed prints are not waterproof. Pigment ink is a solid pigment ground into micron or nanometer particles, relying on the pigment particles on the surface of the paper attached to the text or image, without the need to go deep into the fibers, and has a waterproof and water-resistant, sunlight-resistant and scratch-resistant and other characteristics.
The physical properties of the two are different, the effect of the print is different, can be regarded as two different inks, not recommended for mixed use.
Mixing may lead to problems, such as color instability, chemical reactions may occur, which may lead to changes in color and instability of the problem. If the line of demarcation between different colors is more obvious when dye ink and pigment ink are mixed, then this is an indication that the two inks are less compatible. There is also a risk of plugging, which is easily caused by mixing. Given the differences in the physical properties and printing and coloring methods of the two, mixing is more likely to trigger the risk of plugging.
In addition, pigment ink is usually used in the commercial field of packaging printing, advertising printing, such as product packaging, gift boxes, color cartons, digital printing applications, such as digital Water based polymer carbon pigment ink. Given the application scenarios have been cost considerations, individuals actually rarely used. If mixed use, resulting in unclear prints, not waterproof, printhead equipment loss, so that the product can not be delivered, affecting production, the loss is not worth it. Of course, people engaged in the printing industry know that the two are never mixed.
Different brands of ink formulations are different, it is also recommended not to mix, because the formula of the color paste, concentration, composition ratio are not the same, mixing is also likely to lead to not with its effect. Therefore, it is recommended not to easily mix different brands of the same ink, if you want to replace the brand, it is recommended that the cartridge nozzle clean, and then replaced.
