Canvas bag printing generally uses the following materials:

Water-based pigment: Water-based pigment is an environmentally friendly printing material suitable for use on fabrics. It has good adhesion and durability, contains no harmful substances and is environmentally friendly.

Rubber ink: Rubber ink is a common printing material, characterized by full color and good stability. It can be applied to canvas bags via a printing press or by hand brushing, producing a clear, long-lasting print.

Thermal transfer printing: Thermal transfer printing is a printing technology that transfers patterns to canvas bags through heat pressing. It uses thermal ink, which is transferred to fabric through high temperature and pressure. Thermal transfer printing can achieve high-resolution pattern printing and is suitable for complex patterns and multi-color designs.

Digital printing: Digital printing is an advanced printing technology that directly prints patterns on canvas bags through a digital inkjet machine. It can achieve high-precision, colorful printing effects, and is suitable for personalized customization and small batch production.

During the printing process of these materials, appropriate colors, patterns and printing methods can be selected according to specific needs. The choice of print quality depends on design requirements, cost and expected effects.
