Screen Printing
What is Screen Printing?
Screen printing, also known as silk screening or serigraphy, is a printing technique that involves transferring ink onto a surface through a mesh screen and a stencil. A squeegee (a rubber blade) is used to press the ink through the open areas of the stencil, imprinting the desired design onto the material below.
This method is highly versatile and can be used on a variety of surfaces, including fabric, paper, plastic, wood, metal, and even glass or ceramics. Although commonly used for textiles and posters, it’s also widely employed in packaging, signage, labels, electronic circuits, and three-dimensional objects.
To create the stencil, printers may:
Block areas of the mesh using tape or glue,
Paint directly onto the screen with screen blockers,
Or use a light-sensitive emulsion that hardens when exposed to light, a method similar to photo development.
Designs can be printed in single or multiple colors, but each color requires a separate screen and stencil.
One of the biggest advantages of screen printing is the broad range of ink types and colors it supports, including solvent-based, plastisol, and UV-curable inks, making it ideal for both porous and non-porous surfaces.

How does it work?
Screen printing can be done manually or with machines, but the core process remains the same. The main variations come from the type of ink, the surface being printed, and the visual effect desired. Here's a simplified step-by-step overview:
Step 1: Create the Design
Start by printing your design onto a transparent acetate film, which will later be used to create the stencil.
Step 2: Prepare the Screen
Choose a mesh screen based on the detail of your design:
High mesh count = finer details, thinner ink layer
Low mesh count = more ink flow, less detail.
The screen is then coated with a light-sensitive emulsion, of which there are three types:
Diazo: Inexpensive, slower to cure, not ideal for fine details
SBQ: Fast-curing, great for details, but costly
Dual-cure: A balanced mix, moderate cost and cure time
Step 3: Expose the Screen
Place the acetate film over the coated screen and expose it to bright light. The light hardens the emulsion where it’s not blocked by the design, creating the stencil. For multi-color designs, each color requires a separate screen.
Step 4: Stencil Creation
The screen is exposed to light, hardening the emulsion in uncovered areas. The remaining emulsion is rinsed off, leaving a clear stencil of the design. After drying, any needed touch-ups are made.
Step 5: Setting Up for Printing
The material is placed on the printing board, and the screen is aligned on top in the correct position.
Step 6: Printing the Design
Ink is added to the screen and spread with a squeegee. It passes through the open stencil areas, transferring the design onto the material. After printing, the emulsion is removed so the screen can be reused.
Step 7: Heat Curing
The printed item is heat-cured to set the ink and ensure durability, preventing the design from fading or washing out.
Benefits Of Screen Printing
When considering screen printing, it’s important to recognize its many advantages:
Versatile: Screen printing works on a wide range of materials, fabric, plastic, wood, glass, and metal, with the freedom to use multiple colors and complex designs.
Durable: It applies thick ink layers that resist fading, UV exposure, scratches, and moisture, ideal for outdoor or heavy-use items.
Vibrant Colors: Produces bold, vivid colors that are hard to match with other printing methods. Separate layers help maintain color brightness in multi-color designs.
Cost-Effective for High Volumes:While setup takes time, the cost per item drops significantly with large runs, making it ideal for bulk orders.
Fast and Efficient: Once the screen is ready, printing is quick and repeatable, perfect for mass production of the same design.
Simple Process: Whether manual or automated, the process is straightforward, and the tools are easy and affordable to maintain or replace.
What is Traditional Screen Printing Best For?
Bulk orders
Simple, bold, and solid-color designs
Designs requiring vibrant, high-opacity orders
Orders with a focus on durability
Orders with specialty ink effects
DTF
What is Direct-to-Film?
Direct-to-Film (DTF) printing is a versatile and high-quality method that involves printing a design onto a coated PET film using water-based inks and a special adhesive powder. The printed film is then heat-transferred onto fabric using a heat press, resulting in vibrant, detailed, and durable designs.
Unlike Direct-to-Garment (DTG) printing, which is limited to cotton fabrics, Direct-to-Film works effectively on a wide range of materials, including cotton, polyester, and blends. This flexibility makes it ideal for decorating traditionally challenging substrates.
Direct-to-Film printing offers several advantages for businesses:
Compatibility with various fabrics and materials
Ability to handle high-volume orders with consistent quality
Long-lasting, wash-resistant prints
Excellent color vibrancy and fine detail reproduction
Whether you're producing short runs or large batches, premium DTF printing delivers professional results that stand up to wear and washing.
What is a DTF Printer?
As the name implies, a Direct-to-Film (DTF) printer enables you to print designs directly onto a special film, which can then be transferred to various surfaces, most commonly fabric.
What sets DTF printing apart is its versatility. This technology allows you to print on a wide range of materials, including cotton, polyester, synthetic fabrics, and even silk. It works seamlessly on both light and dark fabrics, without the need for costly A&B transfer paper, making it an efficient and cost-effective solution for high-quality textile printing.
How does it work?
DTF printing offers a relatively fast turnaround compared to other methods, making it an excellent choice for producing detailed designs, even on heavy-duty, outdoor apparel.
Most DTF printers are equipped with multiple ink tanks, typically using CMYK configurations. These specialized inks are formulated specifically for the DTF process, ensuring vibrant, long-lasting results.
Additionally, modern DTF printers are designed without rollers, which eliminates the slippage issues that often caused unwanted lines or streaks in earlier models. This innovation results in smoother, cleaner white layers and more accurate final prints.
If you're seeking a cost-effective, reliable, and high-quality printing solution that delivers flawless results on a wide range of fabrics, DTF printing is a smart and scalable choice.
Step 1: Preparing the Film
The design is first printed in color onto a PET film using a Direct-to-Film printer. A solid white layer is then printed on top to fully cover the design. While the ink is still wet, an adhesive powder is applied evenly, and any excess is removed. Finally, the film is heated, using a curing oven or heat press, to set the adhesive for transfer.
Step 2: Heat Pressing the Fabric
The fabric is pre-pressed to remove moisture and flatten it. Then, the printed PET film is placed on the fabric and heat-pressed at around 165°C for 15–20 seconds to transfer the design.
Step 3: Peeling & Finishing
While still hot, the film is peeled off to reveal the transferred design. The fabric is then heat-pressed again to set the print and enhance durability. After this, the garment is ready for packaging.
Regarding DTF printing, the transferred design has a more uniform feel that doesn’t become thicker no matter how many colors or design elements are added.
What is Direct-to-Film Printing best for?
Cost effective for small-to-medium quantity orders
Orders with multiple fabrics
Vibrant colors and sharp details
Good for intricate, multi-colored designs
