There are many printing processes for customized canvas tote bag, so which kind of printing will be better? Let's analyze it together.
Our commonly used printing screen printing, digital printing, heat transfer printing, sublimation heat transfer printing, these four kinds of printing
Transfer processing transfers the exquisite patterns on the transfer film on the product surface through one-time processing (heating and pressurization) of the heat transfer machine. After forming, the ink layer is dissolved into one with the product surface, which is realistic and beautiful, and greatly improves the grade of the product. However, due to the high technical content of this process, many materials need to be imported.
Before printing to canvas tote bag, the pattern is pre printed on the surface of the film. The printed pattern has rich levels, bright colors, ever-changing, small color difference and good reproducibility. It can meet the required effect of the designer and is suitable for mass production.
The basic principle of screen printing is to use the basic principle that the mesh of the graphic part of the screen printing plate is ink permeable and the mesh of the non graphic part is ink impermeable. When printing, pour ink into one end of the screen printing plate, apply a certain pressure on the ink part of the screen printing plate with the scraping scraper, and move towards the other end of the screen printing plate at the same time. The ink is squeezed from the mesh of the graphic part to the substrate by the scraper during movement.
Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, the scraper is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the scraper. Because there is a certain gap between the screen printing plate and the substrate, the screen printing plate produces a reaction force on the scraper through its own tension, which is called rebound force.
Due to the action of resilience, the screen printing plate is only in mobile line contact with the substrate, while the screen printing plate is in a state of separation without fog and rain, which makes the ink and the screen break, ensuring the printing dimensional accuracy and avoiding rubbing gold and dirty the substrate. When the scraper scrapes the whole layout, it lifts up, and the screen printing plate also lifts up, and gently scrapes the ink back to the original position. This is a printing trip.
In this way, it can be printed on canvas tote bags.
Sublimation heat transfer printing refers to printing the heat sublimation transfer ink on the paper (or plastic film) through printing, and then overlapping the printed paper (or film) with the fabric, heating and pressurizing, and the dye on the paper (or film) sublimates and transfers to the CANVAS TOTE BAGS in a gaseous state.
What is a digital printing system? Digital printing system is a digital and networked technology in the whole process of printing, covering computer direct plate making, digital workflow, digital proofing, on-demand, rapid printing and other technologies. It is the necessity for the printing industry to adapt to the development of the information age and the working principle of digital printing. In today's society, the existence of digital printing began to replace the traditional printing. There are various ways and technologies of digital printing, and the printed products are more perfect.
Our digital printing canvas bag can do not fade, do not fade, and the color is beautiful.
