UV printing is a high-tech plate free full-color digital printing technology. Special UV oily ink can be used to print non absorbent materials. UV ink can be solidified instantly without material limitation. It can be used for color photo printing on a variety of materials. No need to make a plate to finish printing at one time, beautiful and rich color, wear resistance, fast printing image speed, in line with industrial printing standards.

    Advantages: can produce color, gradient, good color restoration, high precision, low price, fast delivery speed (regular size 2 ~ 3 days delivery).

    Disadvantages: compared with the traditional etching process, the durability in harsh environment is still lacking (such as long-term exposure to the sun and rain, etc.).

    Service life: outdoor normal environment can be used for about 1 year, indoor use color 10 years.

    Suitable for customers: excellent use environment (indoor or outdoor sheltered), high color requirements.

    Corrosion process is a traditional metal production process, which needs plate making. After the material is treated, chemical solution is used to react with the metal plate to achieve the purpose of etching the content, and then the content part is manually painted and colored to display the content. The process is mature and has good durability, but it can not be used as gradient color, and the display effect of overlapping part will be hyphenated, The construction period is about 5-7 days after the final draft.

    Advantages: metal etching, clear handwriting, good durability, suitable for harsh environment.

    Disadvantages: can not do gradient, longer construction period, slightly higher price.

    Service life: it can be used for about 8 years in normal outdoor environment and 10 years in indoor environment.

    Suitable for customers: harsh environment (blister, sun exposure, low temperature and other environment), outdoor service life required.
