Information about screen printing
is considered as the most versatile of all printing processes as it can be done on wide variety of substrates of any shape, thickness and size. The screen printing process is simple, and a wide variety of inks and dyes are available for use in screen printing than for use in any other printing process. You can easily find the basic principles, technologies and working methodology of screen printing in a number of websites.
Our Company is dedicated to the art and technology of screen printing. We concentrate on free instruction and information for novice and advanced screen printers, advanced training and workshops for screen printing and share information and techniques relating to screen printing that was not widely available on the internet.
Some specific 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, 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 suitable for use in creative fields. The recently developed rotary screen press allows for continuous operation of the press.
The Screen printing can be done manually or using manual or automatic screen press. All screen printing presses were manually operated till recently. Now, however, most commercial and industrial screen printing is done on single and multicolor automated presses.The rate of screen printing production depends on the drying rate of the screen print inks. Due to remarkable innovations, improved drying systems have developed to significantly improve production rate.
Screen printing has many benefits when compared to the other printing techniques. The following information gives the chief benefits of screen printing: Screen printing can be done on a very wide variety of materials such as paper, plastics, glass, paperboard, metals, cotton and nylon fabrics, ceramic tiles, and many other materials. Even if the material is smooth, porous, uneven, three-dimensional, or of any shape, thickness and size, screen printing is possible. A wide choice of inks, such as conventional solvent-based inks, water-based inks and UV inks can be used for printing. The screen printing plays an important role in the production of products such as posters, labels, decals, signage, and all types of textiles and electronic circuit boards. The thickness of the ink layer can be specified precisely. Hence, screen printing can be used for functional prints such as electrical resistors, rear windscreen heaters for vehicles, coatings, etc. Unlike other printing processes, the thickness of the ink layer can be increased by applying coatings up to 20 times. The ink layer is mainly depending on the mesh and coating thickness.
