What Products Require Processing Before Printing and Ink Curing After Printing?

Various products may require processing before printing and ink curing after printing to ensure optimal results. The specific pre-processing and post-processing steps can vary depending on the type of material, printing method, and ink used. Here are some common examples:

Products Requiring Pre-Processing Before Printing:

1. Textiles and Apparel:

• Pre-treatment: In textile printing, especially with direct-to-garment (DTG) printing, pre-treatment of the fabric may be necessary to improve ink adhesion and color vibrancy. This can involve applying a pre-treatment solution and curing it before the actual printing process.

1. Metal Substrates:

• Surface Preparation: Metal substrates may require pre-processing such as cleaning or applying a primer to ensure proper ink adhesion.

1. Plastics:

• Surface Treatment: Some plastics may need pre-treatment methods like corona treatment or flame treatment to enhance surface energy and improve ink adhesion.

1. Glass:

• Cleaning and Primer Application: Glass surfaces may need to be thoroughly cleaned and, in some cases, a primer may be applied to promote better ink adhesion.

1. Wood:

• Surface Sanding or Sealing: Wooden surfaces may require pre-processing steps like sanding to create a smoother surface or applying a sealer to prevent ink absorption into the wood.

Products Requiring Ink Curing After Printing:

1. Textiles and Apparel:

• Heat Setting or Curing: After printing on fabrics, especially in screen printing and DTG, the printed garment often needs to go through a heat-setting or curing process to ensure the ink bonds properly with the fabric fibers.

1. Plastics:

• Heat Curing or UV Curing: Inks printed on plastic substrates may require heat curing or UV curing processes to set the ink and achieve proper adhesion.

1. Metal Substrates:

• Heat Curing: Metal substrates often undergo a heat-curing process to ensure the ink adheres securely to the surface.

1. Glass:

• Heat Curing: Similar to metal, glass printing may involve a heat-curing process to set the ink.

1. Ceramics:

• Heat Curing: Printing on ceramics, such as tiles or mugs, may involve a heat-curing process to make the ink durable and resistant to wear.

1. Paper and Cardboard:

• Air or Heat Drying: For traditional printing on paper or cardboard, inks may require air or heat drying to set properly.

1. 3D Printed Objects:

• UV Curing: In 3D printing applications, especially with resin-based printers, UV curing is often necessary to solidify the printed material.

It’s essential to follow the specific recommendations provided by the ink and printing equipment manufacturers for each type of material. Proper pre-processing and post-processing steps contribute to the durability, adhesion, and overall quality of the printed products.
