Traditional printing production

Prepress work: The prepress work for production of sublimation transfer papers is important because the dye-based inks used in the production of sublimation transfer papers differ greatly in color before and after transfer. The sublimation transfer ink looks like dark and dull CMYK four colors before transfer (sublimation transfer printing ink does not have white ink), it is rely on about 200 °C high temperature to restore the true color, so give us the production of transfer paper correction and printing tape Difficult to come. Suggestions: (1) First proofing; (2) Adjusting according to customer requirements; (3) Confirming mass production.

Printing equipment: Sublimation transfer paper is usually printed in large quantities using embossing (gravure printing) or lithographic (offset printing), and small batches of screen printing (manual, semi-automatic, fully automatic screen printing), using embossing For printing and screen printing, the amount of ink is large, and it is best to choose pure ink without a diffusion solvent. The lithographic printing ink layer is also thin after the corresponding transfer. Sublimation transfer paper base paper is generally selected 60g-100g offset paper.

Transfer equipment: generally divided into intermittent (flat and curved surface) and continuous (hot roll) two types of hot presses. Intermittent (flat type) for transfer of fabrics or flat ceramics, batch (curved) for transfer of profiled ceramics or shoes, caps, continuous (heat roller) for high volume, large area fabric transfers India.
