BASIC NOTES FOR HEAT TRANSFER PRINTING

 

 

Heat Transfer/Hot Stamping processing is a special kind of printing process, although its working principle is simple, the pressure using silicon roller will spend on the membranes of the graphic by heating transfer to the substrate. However, in the concrete practice of production, to improve the quality of the products and efficiency, needs to note the followings:

BASIC NOTES : Keep the substrates dry, clean, grease-free and, transfer the artworks under the condition of

    • Temperature : 150~200 ° C
    • Speed : 0.4~1.0sec/pcs
    • Pressure: 20~30kg/cm²

** Basic conditions are adjustable according to the materials of the substrates

  1. Clean working environment is required for high quality production.

(1) Make sure the operating machines are clean, not stained with dust, debris, oil or dirt;

(2) To keep clean to spend the heat transfer printing films, should not be infected with smeary, fingerprints, dust, etc.;

(3) To keep the glue head clean, should not have dirt, glue adhesive on it;

(4) The operator’s hand to be kept clean, should not have the sweat, smeary stick to spent membrane or be hot;

(5) To keep stay printed items clean, should not have dust, fingerprints, grease, etc.;

  1. Heat Transfer/Hot Stamping temperature:

Heat Transfer/Hot Stamping temperature according to the hot stamping equipment, hot printing film, hot stamping, and hot stamping area temperatures of different and different, do not blindly pursue the higher the temperature of the hot stamping or (the lower the better), should be in after the stamping as a benchmark to determine the effect of hot stamping temperature, general stamping temperature between 170 ℃ to 240 ℃.

  1. Heat Transfer/Hot Stamping pressure:

Hot stamping pressure to adjust to the most appropriate, if the pressure is too big to hurt gum head and hot product, is too small will affect the hot stamping effect. To adjust to the best stamping pressure should be after adjust the lock, to avoid change in mass production.

  1. Heat Transfer/Hot Stamping time (speed) :

Hot stamping time (speed) should be based on specific stamping content to determine, in ensuring the faster the hot stamping effect under the condition of the higher production efficiency, but some of the products due to the limitation of certain conditions must use slow hot stamping.
