Some Introductions about Screen Printing
Some specific innovations in the screen printing industry have resulted in increasing the production rate and the screen press popularity. Some of the recent technology developments of this industry are development and improvement of U.V. curable ink technologies, development of the rotary screen press which allows continuous operation of the press, development of automatic presses, and improved drying systems.
Screen printing inks are moderately viscous inks which exhibit different properties when compared to other printing inks. There are five different types of screen printing ink which includes solvent, water, and solvent plastisol, water plastisol, and UV curable inks. Improved U.V. curable ink has improved drying rate, thus resulting in increasing the production rate. With such improved ink special effects such as fluorescent color effect can be obtained.
The main types of screen printing presses are the most widely used flat-bed screen press, cylinder screen press, and rotary screen press. Some regular inkjet printers can handle thick, rigid, and flat material and can print on cardboard, poster board, art board, foam core, and can print with pigmented inks. UV curable ink flatbed printers are the printers suitable for use in creative fields. The recently developed rotary screen press allows for continuous operation of the press.
