How to print text or pictures on glass cups?
Print text or pictures on the glass, you can use thermal transfer technology or screen printing technology.
Thermal transfer printing is an emerging printing process, which has been introduced from abroad for more than 10 years. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing adopts dot printing (resolution up to 300dpi), the pattern is pre-printed on the surface of the film, the printed pattern is rich in layers, bright in color, ever-changing, small in color difference, good in reproducibility, can meet the requirements of the designer, and is suitable for mass production; One-time processing (heating and pressure) of the printing machine transfers the exquisite pattern on the transfer film to the surface of the product. After forming, the ink layer and the surface of the product are melted into one, which is realistic and beautiful, and greatly improves the grade of the product.
