What is screen printing?
creen printing, also known as "silk screen printing" or "screen printing", is a very ancient and widely used printing technology. Its basic principle is similar to "template graffiti" - using a template with a pattern to block the areas that do not want to be colored, allowing the ink to pass through the holes in the template and transfer to the substrate.
A Detailed Explanation of the Screen Printing Process
Part 1: Platemaking
Platemaking is the process of creating the printing template. It is the soul of screen printing and determines the quality of the final printed image.
1. Design Preparation
• First, create a digital file of the design to be printed. The design must be a vector image or a high-resolution bitmap and processed in monochrome (usually black). In screen printing, a separate screen is produced for each color.
• The designed design is printed on film. The pattern on the film is opaque black, while the rest is transparent. Printing directly onto transparent film using an inkjet printer is also available.
2. Screen Preparation
• Screen Frame: Typically, aluminum or wooden frames are used. Aluminum frames are lighter, more stable, and suitable for precision printing.
• Screen: A layer of screen mesh is stretched tightly across the frame. Traditionally, silk was used, but polyester (polyester) or stainless steel mesh is now more commonly used. Silk screens come in different mesh counts (the number of openings per square inch). Higher mesh counts have finer openings, making them suitable for printing more detailed designs; lower mesh counts have larger openings, making them suitable for covering large areas and using thicker inks.
• Applying emulsion: In a darkroom (under yellow light), evenly apply emulsion to both sides of the screen. Once completed, place the screen in a light-proof drying oven to dry thoroughly.
3. Exposure
• Place the prepared film (film side down) firmly against the dry emulsion screen.
• Expose the screen using an exposure lamp (usually a strong UV light source).
• Principle: Emulsion hardens when exposed to UV light. The emulsion covered by the transparent portion of the film (i.e., the design) hardens during exposure. However, the emulsion covered by the black portion of the film, which is not exposed to light, does not harden and remains water-soluble.
4. Development
• After exposure, rinse both sides of the screen with a water jet (gentle water pressure).
• The unhardened emulsion (the patterned area) is washed away by the water, revealing the mesh openings. The hardened emulsion, however, adheres firmly to the screen, sealing the openings.
• After development, we have a "template": the patterned areas have transparent mesh openings, while the non-patterned areas have mesh openings sealed by the emulsion.
• Finally, dry the screen again to completely solidify it.
Part II: Printing
Printing is the process of transferring ink from the prepared screen to the substrate.
1. Securing the Screen and Substrate
• Secure the prepared screen to the hinges of the printing press.
• Place the substrate (e.g., T-shirt, paper, plastic, etc.) flatly on the printing platen, using a positioning device to ensure accurate placement every time.
2. Inking and Squeegeeing
• Pour the selected ink onto one end of the screen (the non-patterned area).
• Lower the screen, maintaining a slight distance from the substrate (called the "screen gap").
• Use a squeegee to evenly scrape across the entire screen at a specific angle (usually 45-75 degrees) and with pressure.
• Principle: Under the pressure of the squeegee, ink leaks through the mesh holes in the design area of the screen and onto the substrate below. However, ink cannot pass through the areas of the screen sealed by the photosensitive adhesive.
3. Collecting and Drying the Screen
• After the squeegee is completed, lift the squeegee and screen.
• Carefully remove the substrate and place it on a drying rack or conveyor to dry naturally or in a drying device (such as a drying tunnel) to cure.
• For multi-color printing, all the above steps must be repeated. Each color requires a separate plate and registration, and the next color is overprinted after the previous color has dried (or after rapid drying using a flash dryer). Color registration accuracy is a key measure of print quality.
4. Screen Cleaning
• After the printing job is completed, the ink on the screen must be thoroughly cleaned with a dedicated cleaning agent so that the screen can be recycled and used for the next plate making and printing.
Core Features of Screen Printing
• Advantages:
o Extremely versatile: Prints can be made on almost any surface shape and material (flat and curved surfaces, fabric, glass, metal, plastic, etc.).
o Thick ink layer and vibrant colors: Printed products have a strong three-dimensional effect and covering power, and are particularly suitable for printing highly saturated colors and special effect inks (such as luminous, reflective, and raised).
o Low printing pressure: Friendly to fragile items.
o Relatively low cost: Especially suitable for medium to large-scale production.
• Disadvantages:
o Not suitable for small batches: Plate making costs and time are relatively fixed.
o Poor color gradation reproduction: It is difficult to perfectly reproduce continuous tonal gradations like in photographs.
o Relatively slow printing speed: Especially for multi-color overprinting.
Common Applications
• Textiles: T-shirts, hats, canvas bags. • Advertising products: posters, stickers, flags.
• Electronic products: printed circuit boards (PCBs), instrument panels.
• Glass and ceramics: bottles, cups.
• Plastic products: packaging containers, toys.
What is DTG printing?
DTG printing, the full name is Direct to Garment. You can think of it as a large, high-precision inkjet printer specifically designed for textiles, especially cotton garments.
The DTG process can be summarized into three core stages: "Pre-processing" -> "Printing" -> "Post-processing."
Part 1: Pre-processing
This is a crucial step in DTG printing, directly determining the quality and durability of the final print.
1. Design Preparation
o Create or edit the design you want to print using graphics software (such as Adobe Illustrator or Photoshop) on a computer. DTG offers virtually no design restrictions and can easily handle full-color, high-resolution images with gradients and rich details.
o Files are typically saved in high-resolution PDF, PNG, or TIFF formats.
2. Garment Preparation
o Select a garment suitable for DTG printing. 100% cotton or a high-cotton content garment works best, as cotton fibers absorb water-based inks well.
o Secure the garment flatly on the platen of the print platform. This step is crucial; ensure the garment's surface is absolutely flat and wrinkle-free, otherwise the print head might scratch the fabric.
3. Applying Pre-Treatment
This is a unique and critical step for DTG.
Use a specialized spray gun or applicator to evenly apply a layer of white pre-treat to the area to be printed.
Purpose:
Color Fixation: Provides an ideal base for subsequent colored inks to adhere to, preventing them from seeping into the fabric and causing dullness or smearing.
Color Development: Especially on dark-colored garments (such as black or dark blue T-shirts), the pre-treat forms a white base, allowing subsequent colored inks to appear vibrant (similar to applying a white base before painting on a dark canvas). Pre-treat is equally important for light-colored garments, ensuring vibrant and durable colors.
After application, a heat press is used to briefly heat and cure the garment (approximately 10-20 seconds) to dry the pre-treat and fix it to the fabric.
Part 2: Printing
1. File Submission and Registration
Send the design file to the DTG printer. o In the printing software, precisely locate the print position on the garment.
2. Inkjet Printing
o The print platform, with the garment secured, moves under the print head.
o The printer begins operating like a regular inkjet printer, but its printhead system is more complex and specialized.
o The print head moves very precisely over the garment, spraying tiny ink droplets onto the pre-treated fabric surface.
3. Printing Process:
On light-colored garments: Four CMYK (cyan, magenta, yellow, and black) inks are typically mixed directly to create all the desired colors.
On dark-colored garments: The printing process is divided into two steps:
First White Print: The printer first applies a layer of white ink as a base color over the entire design area.
Second Color Print: CMYK color inks are then applied over this wet white ink layer to create the final color pattern.
Part 3: Post-Processing
After printing, garments cannot be worn directly; they must undergo post-processing to ensure the durability and soft feel of the design.
1. Curing
o Remove the printed garment from the platen and place it in a tunnel dryer or heat press for curing.
o Temperature and Time: Typically, the curing temperature is around 160°C for approximately 2-3 minutes.
o Purpose:Evaporates the water in the ink.Allows the pigments and binders in the ink to heat-set and permanently bond with the fabric fibers. This step ensures the design is washable and wear-resistant.
2. Finishing
o After curing, remove the garment and allow it to cool.
o Perform a final quality check before packaging or direct delivery to the customer.
