Hot stamping small fault original elimination method

　　Hot stamping process is an important part of binding processing, hot stamping processing is a more complex and technical is also very strong work, the hot stamping object is no less than a dozen kinds, different performance, hot stamping materials are very many, to make each variety, each batch of work material hot stamping effect is very ideal is difficult. Therefore, in addition to the selection of materials as required, attention should also be paid to the correct handling of processing in order to ensure the quality of hot stamping. Some hot stamping problems are analyzed and summarized, and the solutions are put forward.

　　1, hot flower or hot stamping is not strong:

　　a. Light pressure or low temperature. -- Increase the pressure or increase the temperature and time

　　b. The stamping material does not meet the ironing material - choose the appropriate stamping material

　　2, hot printing after the dull, paste version is not clear: hot printing temperature is too high, the pressure is too large - reduce the temperature, reduce the pressure

　　3, the same block of hot printing pressure is different: the size of the graphic area is large, the pressure is uneven - the large area of graphic pressure is increased, the paper can be corrected to adjust the size of the area of the pressure is equal

　　4, can not be ironed or ironing off:

　　a. The stamping material does not meet the ironing material - choose the appropriate stamping material

　　b. Hot stamping material adhesive layer quality is not good - temporarily change, check its quality

　　c. The temperature is too low, the pressure is too small - readjust the temperature and pressure

　　d. Helpless adhesive or excessive powder spraying during printing - use adhesive aid to clear the same material of printing powder, normal

　　5, hot stamping good and bad:

　　A. Unstable material quality -- a. Check material quality, temporarily change and record

　　b. Abnormal temperature or pressure - check the temperature, time, pressure, and adjust the hot stamping

　　6, fine lines are not clear:

　　a. The embossed material is too embossed - the embossed pattern fabric should not be embossed with fine line patterns

　　b. The pressure is too light - increase the pressure and temperature to compensate

　　7. Leakage after hot stamping:

　　a. The print is too deep - increase the pressure

　　b. Low pressure, low temperature - increase the temperature by 5℃

　　8, the edge of the handwriting is not obvious after hot printing: the edge of the ironing plate is not uneven or the edge of the handwriting of the ironing plate itself is not prominent

　　A. Before pressing the plate, check whether the pressing layout text is a note, and the unqualified ones should be repaired

　　b. Place a high concave shape on the next plate

　　9, hot plate after hot no convex impression: the bottom plate on the plate pad convex or convex pad is not suitable - the bottom plate hot mark cushion the same concave version of the convex surface, and should be smooth and properly produced

　　10, hot printing color sheet or metal foil does not bond or bond is not strong:

　　a. No auxiliary adhesive - the cover of the fabric should be supplemented with adhesive powder, and the smooth non-porous or less porous cover should be supplemented with viscous fluid

　　b. Inappropriate temperature or pressure - the printing temperature should be moderate
