Screen Printing Shirts Techniques for High-Quality Custom Apparel

Screen printing shirts is a popular method for creating customised apparel with sharp designs and vibrant colours. It involves pushing ink through a stencil on a mesh screen to transfer the image onto fabric, allowing for durable and high-quality prints. Screen printing London is widely used for both small personal projects and large-scale commercial production, and Screen 27 is a leading provider in the field.

Choosing the right design and materials plays a crucial role in the finished product’s appearance and longevity. The process is versatile, supporting various colours and effects that other printing methods might struggle to achieve. Understanding how screen printing London works helps in making informed decisions about design complexity and fabric selection.

Screen Printing Shirt Basics

Understanding the process behind transferring designs onto fabric is essential for producing quality prints. The materials involved and the method's specific steps influence the final product's durability and appearance.

What Is Screen Printing?

Screen printing London is a printing technique where ink is pushed through a mesh stencil onto fabric. This method allows for vibrant, long-lasting designs, especially on textiles like shirts.

A screen, typically made of polyester mesh, holds the stencil of the design. When ink is applied and forced through the screen, it only passes through the open areas of the stencil. This creates a precise image on the shirt.

The process is ideal for both simple and complex designs, accommodating multiple colours while maintaining sharp detail. Screen 27 uses this method for custom apparel production due to its efficiency and quality results.

How Screen Printing Works

Screen printing London involves several clear steps. First, a design is created and converted into a stencil on a mesh screen. Each colour in the design requires a separate screen.

During printing, the shirt is placed under the screen. Ink is then spread across the mesh with a squeegee, pressing ink through the stencil onto the fabric.

After printing, the shirt must be dried or cured using heat to fix the ink permanently. Proper alignment, known as registration, is critical for multi-colour designs to match accurately.

Types of Shirts Suitable for Screen Printing

Cotton shirts are the most common choice for screen printing London due to their absorbency and smooth surface, which holds the ink well. Ringspun cotton offers a softer feel and better print quality than regular cotton.

Blends such as cotton/polyester can also work but may require special inks or processes to ensure the print adheres properly. Synthetic fabrics often pose challenges due to their texture and ink absorption.

Fabric weight affects print quality too. Medium to heavyweight fabrics prevent ink bleed-through and provide a crisp print.

Design Considerations for Screen Printing Shirts

Effective screen printing London requires careful choices in artwork, colour selection, and print placement. These factors influence the final appearance, durability, and cost of the printed shirts.

Selecting Artwork and Colour Palettes

Artwork for screen printing London should be clear with bold outlines to maintain sharpness after printing. Simple designs with limited fine details work best since complex patterns can lose definition during the printing process.

Colour choices must consider the shirt fabric colour and ink opacity. Use spot colours instead of gradients, as the latter are challenging to reproduce with screens. Typically, up to four colours are economical; more colours increase setup costs and complexity.

Pantone Matching System (PMS) colours are preferred for consistency. Bright or neon inks may require special handling but can enhance visual impact on darker fabrics.

Preparing Designs for Printing

Design files should be created or converted into vector formats such as .AI or .EPS for scalability without loss of quality. Raster images need to be high resolution (minimum 300 dpi) but vector graphics are ideal for crisp lines.

Separate each colour into individual layers, clearly defined for screen preparation. Use solid colours rather than gradients or halftones unless specialised techniques like simulated process printing are applied.

Ensure all fonts are converted to outlines to prevent issues with missing fonts during printing.

Optimising Print Placement on Shirts

Print placement impacts comfort, visibility, and aesthetic appeal. Common areas include the centre chest, upper back, sleeves, or haem (bottom edge). Centre chest is most popular for logos and simple designs.

Proper alignment and sizing depend on shirt size and intended audience. Smaller prints can look lost on larger shirts, while oversized prints may buckle on smaller sizes.

Consider the shirt seams, collars, and possible folds that may distort the image. Test prints or mock-ups help confirm the best positioning and scale before mass production.

Screen Printing Process and Techniques

Screen printing London involves several precise steps, specific ink types, and curing methods to ensure durability and quality. Understanding each component helps achieve accurate, long-lasting prints on shirts.

Step-by-Step Printing Method

The process begins with creating a stencil or screen, usually from a fine mesh stretched over a frame. A design is transferred onto this screen by blocking out areas where ink should not pass.

Ink is then applied to the screen's surface and pushed through the open mesh using a squeegee, pressing the ink onto the shirt beneath. This process is repeated for each colour in the design, with separate screens used.

After printing, the shirts are carefully aligned to maintain the design’s consistency.

Popular Ink Types and Their Benefits

Plastisol ink is the most common, prized for its durability and vibrant colours. It sits on top of fabric fibres, creating a slightly raised print that resists fading. Plastisol requires heat curing to set properly.

Water-based ink penetrates the fabric, resulting in softer prints with a more natural feel. It is eco-friendly but can be less vibrant on dark garments and requires more care during curing.

Discharge ink removes the shirt’s dye and replaces it with pigment, producing bright, soft prints on dark fabrics.

Curing and Finishing Methods

Proper curing fixes the ink to the fabric and ensures wash resistance. This generally involves heating the printed shirt to approximately 160°C (320°F) using a conveyor dryer or heat press.

Insufficient curing causes ink to wash out or crack over time. Over-curing can lead to scorch marks or fabric damage, so temperature and timing must be carefully controlled.

Finishing may include post-print treatments like softeners for water-based inks. Quality control ensures prints are properly cured, aligned, and free of smudges.

Care, Maintenance, and Longevity

Proper care of screen printed shirts extends their lifespan and keeps the design intact. Attention to washing and storage conditions plays a crucial role in maintaining the print’s appearance and fabric quality.

Best Practices for Washing Screen Printed Shirts

Screen printed shirts should be washed inside out to protect the ink from friction and abrasion during the wash cycle. Using cold water is essential, as hot water can cause the print to crack or fade over time.

It is best to use a gentle cycle with mild detergent, avoiding bleach or fabric softeners that break down the print and fabric fibres. Air drying is recommended over machine drying since high heat can warp or peel the ink.

If using a dryer, choose the lowest heat setting. Ironing directly on the print should be avoided; instead, the shirt can be ironed inside out or using a protective cloth over the design.

Preserving Print Quality Over Time

Long-term preservation of screen printed shirts depends largely on storage and handling. Keeping shirts folded or hung in a cool, dry place prevents moisture damage and ink degradation.

Exposure to direct sunlight should be minimised, as UV rays can cause fading of both fabric and print. Commercial screen printing London inks are durable but can become brittle if repeatedly stressed by harsh cleaning or rough wear.

Screen 27 recommends regular inspection for minor cracks or peeling to allow early intervention. Proper care in use and maintenance ensures your screen printing London shirts maintain their original appearance.
