Many people ask if
water-based ink can be used to print adhesive labels. Of course, it is possible. Water based ink can already be printed on paper and plastic film surfaces. Let's take a look at some of the advantages and disadvantages of using water-based ink to print adhesive labels.
advantageEnvironmental friendliness:
Water based ink uses water as a solvent and does not contain toxic volatile organic compounds (VOCs), which is environmentally friendly and meets modern environmental requirements.
Beneficial to human health, reducing harm to printing workers and the surrounding environment.
Water based ink is not easy to burn, reducing the risk of fire and improving production safety.
Printing effect:
With the development of technology, the performance of water-based inks in terms of glossiness, color vividness, and other aspects has been significantly improved, which can meet the printing needs of self-adhesive labels.
The printing effect of water-based ink on materials such as PET polyester film is excellent, achieving high reproducibility and stable and reliable print quality.
Economy:
Although the raw material price of water-based ink may be slightly higher than some solvent based inks, considering its environmental friendliness and low harm to human health, using water-based ink is more economical in the long run.
shortcomingDrying speed:
Compared to solvent based inks, water-based inks have a slower drying speed. This may lead to a decrease in production efficiency, especially in high humidity or low temperature environments.
Slow drying speed may also lead to problems such as adhesion and blurring during the printing process, affecting the printing quality.
Adhesion:
Water based ink requires high surface tension of the printing material. If the surface of the material is not properly treated, it may lead to poor ink adhesion and affect the printing effect.
For certain special materials (such as certain plastic films), the adhesion of water-based ink may not be as good as solvent based ink.
Equipment adaptability:
Water based ink may have poor compatibility with certain printing equipment, such as ink being prone to skin formation and clogging of filters in the ink tank.
This requires printing companies to make appropriate adjustments and maintenance to their equipment before using water-based ink.
Printing stability:
The pH value of water-based ink may be unstable and requires regular testing and the addition of stabilizers to maintain its stable performance.
This increases the operational complexity and cost during the printing process.
In summary, water-based ink has the advantages of environmental protection, safety, and good printing effect when printing adhesive labels, but it also has disadvantages such as drying speed, adhesion, equipment adaptability, and printing stability. Therefore, when choosing ink, it is necessary to consider comprehensively based on specific printing needs and conditions.
