1 TRANSFER PRINTING TRANSFER OF DESIGN FROM ONE SUBSTRATE TO ANOTHER FIRST SUBSTRATEPAPER SECOND SUBSTRATEFABRIC

2 CONVENTIONAL PRINTING SEQUENCE PRINT> DRY > DYE FIXATION > WASH >DRY EQUIPMENTS PRINTING MACHINE HOT AIR DRYER/DRYING CYLINDER /STENTER DYE FIXATION: STEAMING/DRY HEAT STEAMER: ATMOSPHERIC, PRESSURE, HIGH TEMPERATURE DRY HEAT: STENTER WASHING: OPEN SOAPER, JIGGER, WINCH HIGH CAPITAL INVESTMET LARGE SPACE

3 TRANSFER PRINTING DEVELOPED IN 1968 FOR PRINTING POLYESTER SEQUENCE PAPER PRINTING > DRYING > TRANSFER OF DESIGN FROM PAPER TO FABRIC EQUIPMENTS PAPER PRINTING MACHINE TRANSFER PRINTING MACHINE LOW CAPITAL INVESTMENT SMALL SPACE REQUIREMENT

4 ADVANTAGES IDEAL FOR PRINTING GARMENTS NO SECONDS DUE TO PRINTING FAULTS NO WASHING AFTER TRANSFER LOW CAPITAL INVESTMENT LOW SPACE REQUIREMENT NO SPECIAL SKILL REQUIRED LOW ENERGY AND WATER CONSUMPTION FREE FROM POLLUTION PROBLEM

5 TRANSFER PRINTING METHODS SUBLIMATION TRANSFER MELT TRANSFER FILM RELEASE TRANSFER WET OR MIGRATION TRANSFER

6 SUBLIMATION TRANSFER DYEDISPERSE DYE FIBREPOLYESTER SELECTED DISPERSE DYES CAN BE USED FOR PRINTING NYLON AND ACRYLIC METHOD NOT SUITABLE FOR PRINTING COTTON, WOOL AND SILK WITHOUT CHEMICAL MODIFICATION OF FIBRE

7 DISPERSE DYE SUBLIMATION TEMPERATURE 180-200 0 C GOOD AFFINITY TO FABRIC TO BE PRINTED NO AFFINITY TO PAPER GOOD FASTNESS PROPERTIES SIMILAR RATE OF VAPORIZATION WHEN USED IN MIXTURE

8 PAPER BLEACHED CRAFT PAPER CLAY COATED WEIGHT45-70 gsm pH NEUTRAL NO METAL CONTAMINATION GOOD INITIAL STRENGTH GOOD STRENGTH RETENTION AFTER HEAT TREATMENT

9 PAPER PRINTING METHODS BATCH PRINTING SCREEN PRINTING LETTER PRESS PRINTING LITHO OR OFFSET PRINTING CONTINUOUS PRINTING GRAVURE PRINTING FLEXOGRAPHIC PRINTING ROTARY SCREEN PRINTING

10 PRINTING INK COMPOSITION DISPERSE DYE (PURE, COMMERCIAL) MEDIUM (WATER, SOLVENT) THICKENER (WATER SOLUBLE, SOLVENT SOLUBLE) THEMOPLASTIC ADHESIVE TO MAINTAIN FIRM CONTACT BETWEEN PAPER AND FABRIC DURING TRANSFER
