Nothing disappoints customers faster than a print that cracks, peels, or starts falling apart after a few washes. Most printers assume the ink is to blame, but in reality, cracking and peeling are usually caused by curing problems, poor adhesion, or using the wrong ink for the garment.

At One Stroke Inks, we help printers troubleshoot these issues every day. A few simple adjustments can make the difference between prints that fail and prints that last for years.

Why Prints Crack Or Peel

Several things can cause print failure:

In most cases, curing is the first place to investigate.

Under-Curing Is The Most Common Problem

Plastisol ink does not air dry. It must reach its proper cure temperature throughout the entire ink deposit.

A print may feel dry on the surface but still remain uncured underneath. After washing, the ink can crack, split, or peel away from the garment.

Always verify temperatures with an infrared thermometer and perform wash tests before running production.

Use The Right Ink For The Garment

Cotton garments are forgiving and work well with most standard plastisol inks.

Polyester and blended fabrics present additional challenges. Heat can cause dye migration, and some fabrics require low-cure or low-bleed formulations.

Products such as Poly Trans 25 Series, Underbase LC White, and Soft FX LC Series are designed to help reduce these problems.

White Ink Quality Matters

White ink is often applied heavier than other colors. Thick deposits require proper curing to maintain flexibility and durability.

Reliable white inks such as 2001 Dream White, Super Smooth White, and MIA White are formulated to provide excellent opacity and flexibility when cured properly.

Too Much Ink Can Create Problems

Many printers assume that thicker prints are stronger. In reality, excessive ink deposits can make prints stiff and more prone to cracking.

Multiple controlled layers often produce better durability than one extremely heavy deposit.

Proper mesh selection and squeegee pressure also help create smoother, more flexible prints.

Over-Curing Can Damage The Ink

Too much heat can be just as harmful as too little.

Excessive temperatures can make the ink brittle and increase the likelihood of cracking over time. Polyester garments are especially sensitive to overheating.

Following the manufacturer's cure recommendations helps maintain flexibility and wash durability.

Stretching Is Normal, Cracking Is Not

Good prints should flex with the fabric.

After curing, gently stretch a test print. Properly cured ink should remain smooth without visible cracks.

Minor texture changes are normal, but large cracks or separation indicate a curing issue.

Wash Testing Is Your Best Insurance

The easiest way to verify durability is with a wash test.

Print a sample garment, cure it properly, and wash it several times using normal laundry settings.

If the print remains smooth and vibrant, your process is working correctly.

Many professional printers perform wash tests whenever they change inks, garments, or curing equipment settings.

Specialty Inks Require Extra Attention

Puff, glitter, metallic, and other specialty inks often have different curing requirements.

Products such as 680 Puff Series, Glitter Series, and 180 Metallic Series should always be tested before large production runs.

Following recommended curing procedures helps maximize durability and appearance.

How To Get Prints That Last

Reliable prints begin with good habits:

Durability Starts With The Entire Process

There is no single ink that magically prevents cracking and peeling. Long-lasting prints come from combining quality inks with proper printing and curing techniques.

At One Stroke Inks, we formulate our products to provide excellent flexibility, opacity, and wash resistance. Matching the right ink to the garment and curing it correctly helps ensure that your customers enjoy prints that continue looking great long after they leave your shop.
