Notes On Printing Handbags

As a common way of promoting and protecting products, handbags not only provide convenience for shoppers, but also serve as an opportunity to promote products or brands again. Although there are many types of it, most of them are rectangular and have relatively standardized shapes. Generally, offset printing technology is used to complete the printing. Below, we will introduce the precautions for printing:
1. During the printing process, due to the volatilization of water, the viscosity of ink can increase and the pH value can decrease. The pH value should generally be controlled between 8.5 and 9.5, and pH stabilizers can be used to adjust it to maintain the stability of viscosity and pH.
2. When using ink for printing handbags, use a stirring rod to stir the ink evenly in the bucket, measure its viscosity, and pour it into the ink tank. If the viscosity is too high or too low, diluents or thickeners can be added for adjustment.
3. Due to the fact that ink is a pure water-based system, it is advisable to avoid mixing ink with alcohol based ink and solvent based ink or adding solvents to ink during printing to avoid printing quality issues.
4. The ink for printing should be stored indoors, with a room temperature generally between 5 ° C and 50 ° C.
5. The printing suitability of ink is influenced by objective conditions such as printing conditions, surface characteristics of the substrate, environmental temperature and humidity, and the length of ink storage time. Therefore, when using ink for printing, it is necessary to use some additives to make slight adjustments to the ink to achieve better printing results.
The use of ink is very important in the printing process of handbags, and everyone must pay attention when using it.
