CHOOSING THE RIGHT BLANK T-SHIRT FOR SCREEN PRINTING: AVOIDING SHRINKAGE AFTER WASHING

Introduction

When it comes to creating high-quality custom t-shirts through screen printing, one of the biggest concerns for businesses and organizations is ensuring the finished product maintains its size and shape after washing. Shrinkage can distort designs and frustrate customers or teams. At Underground Printing, we understand how important it is to pick the right blank t-shirt that’s screen-print-ready and resistant to washing shrinkage. This guide will help you select the right blank t-shirt that minimizes fabric shrinkage and keeps your custom apparel looking sharp.

Why Does T-Shirt Shrinkage Happen?

T-shirt shrinkage typically occurs due to the fabric content and manufacturing processes. The most common causes include:

• Material Type: Natural fibers like cotton tend to shrink more than synthetic ones.
• Fabric Pre-Shrinking: Some shirts are pre-shrunk, which helps reduce further shrinkage.
• Washing & Drying: High heat in washing machines and dryers causes fibers to contract.
• Garment-Dyeing Processes: Certain dyeing methods, like garment-dyeing, can cause additional shrinkage.

Understanding these factors helps when choosing blanks that provide longevity for your screen printing projects.

Fabric Content and Its Impact on Shrinkage

Blank t-shirts are available in various fabric compositions. Here's how common fibers affect shrinkage:

• 100% Cotton: Classic and popular for screen printing due to its softness and ink absorption, but it’s prone to shrinkage unless pre-shrunk.
• Ring-Spun Cotton: A softer and more durable cotton variant that often resists shrinkage better than standard cotton.
• Blends (Cotton/Polyester): These offer reduced shrinkage due to polyester's stability and moisture-wicking features, though the feel differs slightly from pure cotton.
• 100% Polyester: Minimal shrinkage, but can be less comfortable and less ideal for certain screen printing inks.

For most businesses looking for a balance of comfort, print quality, and shrink resistance, cotton/polyester blends are excellent choices.

Choose Pre-Shrunk or Preshrunk Shirts

Look specifically for blank t-shirts labeled as pre-shrunk or preshrunk. This means the garment has been treated to shrink before sale, greatly reducing the risk of surprising size changes after printing and washing. Many popular blanks from brands like Gildan, Bella+Canvas, and Next Level offer pre-shrunk options.

When customizing apparel at Underground Printing, you can select quality pre-shrunk shirts to ensure your order is consistent and long-lasting.

Weight & Fabric Quality Matter

Heavier weight fabrics (measured in ounces per square yard) tend to shrink less and offer more durable screen printing surfaces. A 5.5 oz or 6 oz shirt generally shrinks less than a lightweight 4.3 oz tee.

Also consider fabric quality: higher quality yarns and knitting techniques minimize distortions and shrinkage.

Type of T-Shirt Style and Fabric Finishing

Some blank t-shirts feature garment-dyeing or special finishing that can cause varying shrinkage. For example, Comfort Colors shirts, known for their pigment dyeing, have a vintage feel but may experience up to 5% shrinkage due to the finishing.

If shrinkage is a top concern, avoid garment-dyed shirts or account for slight size variations.

Washing and Care Instructions to Minimize Shrinkage

Even with the right blanks, proper care extends your apparel's life:

• Wash in cold water
• Use gentle cycles
• Avoid high heat drying; air dry or tumble dry low
• Turn shirts inside out before washing to protect print
• Follow any care tags or recommendations from your custom apparel provider

Proper care can reduce shrinkage and preserve screen print quality longer.

FAQ

Q: Do all cotton shirts shrink after washing?

A: Most cotton shirts shrink to some extent, especially if not pre-shrunk. Pre-shrunk or blended shirts minimize this effect.

Q: Can blending cotton with polyester stop shrinkage completely?

A: It reduces shrinkage significantly but does not always stop it entirely. Proper washing care is still important.

Q: What fabric weight is best for screen printing to avoid shrinkage?

A: Medium to heavyweight shirts (5.5–6 oz) typically experience less shrinkage and provide a good canvas for printing.

Q: Does fabric shrinkage affect screen printing ink?

A: Excessive shrinkage can crack or distort prints. Selecting the right fabric helps maintain print quality.

Q: How can I order blanks that are guaranteed not to shrink?

A: While no fabric is completely shrink-proof, choosing pre-shrunk blends, heavier weights, and following care instructions greatly reduces shrinkage risk. At Underground Printing, we help you select these options.
