Customization of canvas bags generally uses screen printing, which is often referred to as “silk printing”. This is a more commonly used printing process, and it is also a printing process often recommended by factories for customers. However, as many customers continue to improve the exquisite printing of products and environmental protection requirements, they also constantly adjust the printing process of the printing workshop, and canvas bag manufacturers can adapt to the higher requirements of more customers for the printing process.

I. Watermark

It is named because of its use of water-based elastic glue as the printing medium. It is more common in textile printing and is also called printing. Blend the color paste and water-based elastic glue when printing. No chemical solvents are used when washing the printing plate, it can be washed directly with water. It is characterized by good tinting strength, strong covering and fastness, washing resistance, and basically no peculiar smell. This printing process is generally charged according to the number of colors and the size of the printing area, but basically because of its low production cost, the price will not be too high for canvas bag manufacturers. What’smore, it can use to polyester bag,  oxford bag, non woven bag, velvet bag, etc…

2.Gravure printing

The finished product processed in this way is usually called a laminated canvas bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print the image and text on the film, and then the film with the pattern is laminated on the canvas by the laminating process. Generally, canvas bags printed with large-area color patterns use this process. Its characteristic is that the printing is exquisite, the whole process is produced by machine, and the production cycle is short (but the plate-making time is longer). In addition, the product has excellent waterproof performance, and the durability of the finished product is better than canvas bags produced by other processes. The film is available in bright and matt, and matte has a matte effect! This kind of custom printing process for canvas bags is generally charged according to the printing color, and its production cost is higher than that of the watermark. At the same time, the plate-making cost of this printing process is also relatively high. Therefore, for some orders with a relatively small number, no It is recommended to use.

3.Thermal transfer

Thermal transfer is a special type of printing in the custom printing of canvas bags. This method requires an intermediate medium, that is, first print the graphic on the thermal transfer film or thermal transfer paper, and then transfer the pattern to the canvas by heating by the transfer equipment . The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich layers, comparable to photos. Suitable for small area color image printing. This kind of printing process charges according to the printing area, that is to say, the large printing area is more expensive than the small printing area. Therefore, for large-area printing patterns, it is not recommended to use this printing process for canvas bag manufacturers.
