HONGSAM released revolutionary PET film transfer printing solution without powder for cotton and other printing media


Sublimation digital printing solution has promoted the popularization of digital printing on polyester fabrics and provided a ubiquitous short-process digital printing method for various industries. However, the short-process digital printing technology of cotton and blended fabrics is a pain point in the industry. In 2020,“PET film transfer printing solution with powder”pioneered by the Chinese came out, ushering in a development climax in the popularization of digital transfer printing of various fabrics. Chinese original digital printing solution goes globally, bringing the gospel of short-process and water-free digital printing to various industries.


Everything has its strengths and weaknesses, the advantages and disadvantages of any solution must coexist. This depends not only on the diversity of printing media, process requirements, functional requirements. Moreover, this is a complex and beautiful world, consumers are qualified to have more needs.


Sublimation printing is for polyester, “PET film transfer printing solution with powder” gives a solution for cotton and other printing media. Due to the inevitable problems in the process of shaking powder film transfer printing, such as the requirements of fine pattern transfer, hand feeling and air permeability, there may be problems as low yield of finished products and difficult maintenance of equipment and process. In view of the inevitable defects in the film transfer printing and based on 15 years of experience in the development of pigment inks, hongsam digital released revolutionary PET film transfer printing solution without powder for cotton and other printing media. Its revolution lies in that this solution solves the natural defects of “PET film transfer printing solution with powder”, it becomes a very good complementary solution in the field of digital printing, adds a more down-to-earth solution to prosper the digital printing.

The printing process of this solution is shorter, and the whole process has only three steps: 

printing-drying-transfer. This is similar to sublimation transfer on polyester, except that the PET film is instead of the sublimation paper, and there is no "powder shaking" process, which reduces the probability of defective products and avoids many problems with the powder shaking solution.


Comparison of the cost: almost same with “PET film transfer printing solution with powder” solution.

Its main characteristics are simple operation, multi-application, no hand feeling, good fastness and high yield.


Some netizens exclaimed: This is simply we can transfer print where we want, mom no longer has to worry about my digital printing!

Based on the existing data and industry knowledge, we compared this solution with sublimation transfer, PET film transfer printing solution with powder, DTG pigment printing, and eco-solvent printing as follows. Only represents a part of the views, may not be comprehensive and scientific, just to set the ball rolling.

First of all, let’s see the difference between “PET film transfer printing solution” with “PET film transfer printing solution without powder”:
