Each ink type has its pros and cons and impacts the final print in different ways. Understanding how different ink types impact the final print will help you make an informed decision when selecting your printing machine.
Different types of screen printing machines
Manual screen printing machine: A manual screen printing machine is used for low-volume printing projects. It consists of a frame, a screen mesh, and a printing unit. The frame holds the mesh and provides support for the unit. The unit is typically a computerized device that contains a printer, ink jets, and other components needed to print.
Automatic screen printing machine: An automatic screen printing machine automates the printing process. It has a frame, a screen mesh, and a printing unit. The frame holds the mesh and provides support for the unit. The unit is typically a computerized device that contains a printer, ink jets, and other components needed to print
Flat bed screen printing machine: A flat bed screen printing machine is used for larger prints on flat materials such as fabric, metal, and paper. It has a frame, a screen mesh, and a printing unit. The frame holds the mesh and provides support for the unit. The unit is typically a computerized device that contains a printer, ink jets, and other components needed to print.
Rotary screen printing machine: A rotary screen printing machine is used for large area prints on cylindrical objects like mugs and bottles. It has a frame, a rotating drum with screens attached to it called an Ink Rotator,and printing units in each of its four corners .The unit connects to the printer via USB or serial cable
Factors to consider while selecting a screen printing machine
There are a number of factors to consider when selecting a screen printing machine, including the size of the graphics and the type of print desired. A good starting point is to assess the type of printing process used on the machine. (For example, hot-press or t-shirt printing.) Depending on the process, different machines offer varying levels of ease of use, accuracy and precision.
A machine's size and weight should also be taken into consideration. Some machines are compact and easy to move around, while others are large and heavy. A machine's operating speed and other settings, such as pressure and temperature, should also be considered. Look for a machine with easy-to-use controls, such as digital displays and intuitive navigation buttons. Finally, it is essential to check whether the machine is compatible with other equipment or software programs.
Commonly used materials in screen printing
Fabric: In screen printing, fabric is used to transfer ink onto the screen. Fabric used in a screen printing process can vary from natural fibers such as cotton and silk, to synthetic materials such as polyester and nylon. Natural fibers are preferable for their durability and strength. They are able to hold ink well and provide a good base for the ink to adhere to.
Ink: Different types of ink can be used for different effects. Ink can be water-based or solvent-based. Water-based ink is usually thinner, thus creating a watercolor-like effect on the screen. The solvent-based ink is thicker, creating a darker, more pronounced effect on the screen. Many fabrics can be used for screen printing with different impacts on the final product.
Screens: Screens are available in various sizes and mesh counts. Some fabrics cannot be printed on mesh screens due to their texture or nature of the fabric. Emulsions are popularly used in screen printing as they help transfer designs onto fabric easily without affecting its texture or quality.
Different techniques used in screen printing
- Manual screen printing: This is the oldest and most common form of screen printing. Unlike digital printing, the ink is applied by hand via a squeegee or blade. This method can be used for printing on items such as t-shirts, blankets, and posters.
Direct-to-garment (DTG) printing: This process uses inkjet printers to print designs directly onto fabric. It's an efficient way to create unique designs quickly and accurately.
Automatic screen printing: Automated machines are used for this process. They're designed for mass production, making it an ideal option for large-scale printing jobs. The machines use patented technology that ensures high-quality prints every time. Plus, they're capable of printing on various substrates, such as t-shirts and garments.
Heat transfer printing: In this method, hot plates are used to apply heat and pressure to the garment. This allows the design to be transferred onto it easily without damaging the garment or the design itself.
These techniques offer various benefits and each has its pros and cons. You should consider which one suits your needs best before deciding on a particular method for your next screen printing job.
