  2. Types of Transfers: • Cold Peel • Hot Peel • Hot Split • Litho • CMYK • Puff • PVC free

  3. Cold Peel TransfersSimple and easy to produce • Supplies needed: • Direct printing inks (Excalibur 500, 550, 551 and all white plastisol series). • Coated release paper. (Artsan, T-75 or equivalent). • Stencil made with coarse mesh. (30-62T). • Adhesive system. • Hot melt Powder. (C-57 or H-10). • Printable adhesive. (846 or 842). • Heat press.

  4. Cold Peel TransfersStencil • Choose coarse mesh ranging from 30-62T depending on the image itself. Transfers require a large amount of ink deposit on the paper. This will ensure good opacity, durability and release. • Use a high solids content emulsion to build a “thick” deposit on the print side of the screen. This will help to minimize “saw tooth” edges in stencils on coarser mesh. • Mirror your artwork before outputting the film positives. The image is printed in reverse on the paper. This way when it is transferred onto the garment it is right reading. • Print order is opposite of what would be used in direct printing.

  5. Transfer paper is a moderately porous substrate. Line definition in the stencil must be sharp or the imprints will recreate the imperfections. Alternately, textile (cotton) is very porous which will absorb excess ink. Although line definition is important the textile will hide imperfections. Paper will not.

  6. Cold Peel TransfersHow to produce a one colour transfer • Hot melt powder adhesive: Screen print Excalibur direct print plastisol onto the paper. Apply powder adhesive then run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). • Printable adhesive: Screen print Excalibur direct print plastisol onto the paper. Run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). Bring the paper back to the press and print the printable adhesive. Run through a conveyor dryer to gel. note: the printable adhesive layer should trap the foreground colour completely.

  7. Cold Peel TransfersHow to produce a two colour transfer where the inks do not touch • Hot melt powder adhesive: Screen print Excalibur direct printing plastisol onto the paper. Apply powder adhesive and then run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). Bring the paper back to press and repeat with second colour. • Printable adhesive: Screen print Excalibur direct printing plastisol onto the paper. Run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). Bring the paper back to the press and print the second colour. Run through a conveyor dryer to gel. Bring the paper back to press and print the printable adhesive. Run through a conveyor dryer to gel. note: the printable adhesive layer should trap the foreground colours completely.

  8. Cold Peel TransfersHow to produce two colour transfer where the inks overlap • Hot melt powder adhesive: Screen print Excalibur direct printing plastisol onto the paper and run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). Bring the paper back to press and print the second colour. Apply powder adhesive and run through the conveyor dryer to gel. • Printable adhesive: Screen print Excalibur direct printing plastisol onto the paper. Run through a conveyor dryer to gel. The imprint should reach an internal temperature of 110C (230F). Bring the paper back to the press and print the second colour. Run through a conveyor dryer to gel. Bring the paper back to press and print the printable adhesive. Run through a conveyor dryer to gel. note: the printable adhesive layer should trap the foreground colour completely.

  9. Cold Peel TransfersApplication • Ensure that the imprints are not cured on the paper. The ink should only be brought to a gel state. Final curing happens when the imprint is transferred onto the garment. The heat and pressure generated by the press will cure and glue the imprint to the fabric. This ensures maximum washability, release from the paper and opacity. • Transfer at 176C (350F) for 12-15 seconds.

  10. Hot Peel TransfersDesigned to release completely from the paper without the aid of an adhesive system • Supplies needed: • Specific ink line made for hot peel transfers. (960 series). • Coated release paper. (Artsan, US-3000 or equivalent). • Stencil made with coarse mesh. (30-62T). • Heat Press.

  11. Hot Peel Transfers How to produce • Printing parameters are the same for hot peel as cold peel. The only difference is the omission of an adhesive system and the use of specialty inks. • Gelling temperatures must be maintained. If the ink cures on the paper there is no adhesive system to assist it in transferring and releasing. The ink must cure during the transfer process.

  12. Hot Peel Transfers • Application: • 190C (375F) - 204C (400F) for 6-8 seconds. • Peel paper away while the ink is still hot. • The ink will completely release from the paper and make an opaque imprint that sits inside the fabric.

  13. Hot Split TransfersDesigned to split at time of transfer. 75% of the imprint transfers to the textile, 25% stays on the paper • Supplies needed: • Specific ink line made for hot split transfers. (900/950 series). • Uncoated release paper. (Soft Trans-88). • Stencil made with coarse mesh. (30-62T) • heat press.

  14. Hot Split Transfers How to produce: • Printing parameters are the same for hot split as cold peel. The only difference is the omission of an adhesive system and the use of specialty inks. • Gelling temperatures must be maintained. If the ink cures on the paper it will not split evenly. Opacity, handle and washability will be compromised.

  15. Hot Split Transfers • Application: • 190C (375F) - 204C (400F) for 6-8 seconds. • Peel paper away while the ink is still hot. • 75% of the ink will completely release from the paper while 25% will stay behind. The finished imprint will have a very soft handle.

  16. Cold Peel Transfers Hot Peel Transfer Hot Split Transfers Considerations: • Printable adhesive systems are necessary for Cold Peel Transfers. They are also compatible with Hot Peel and Hot Split Transfers. The adhesives will provide a stronger bond to the fabric and better washability. • Hot Split inks can be used on coated paper. The result will be a full release similar to Hot Peel transfers. • Hot Peel and direct printing inks can not be used on uncoated paper. They will not properly release even when using an adhesive system. • Printable adhesive systems can be mixed into direct printing inks to make cold peel transfer inks. Ratio ranges from 25-50% by weight. This method will compromise opacity.

  17. Lithographic TransfersHigh Speed Production • System whereby high speed lithographic presses print high resolution CMYK images onto coated paper. After printing, a plastisol backing is screen printed and an adhesive system is applied to enable the high quality image to be transferred onto textile. • Magazine type resolution dependant images can be produced for textiles. • Extremely fast production times can be achieved. • Special effects like puff and glitter can be incorporated.

  18. Lithographic Transfers High Speed Production • Supplies needed: • Litho transfer inks (Excalibur 996). • Plastisol backing white or clear (Excalibur 554 clear, 555 white or 556 white for polyester). • Coated release paper. (Artsan, T-75 or equivalent). • Lithographic printing press. • Adhesive system. • Hot melt Powder. (C-57 or H-10). • Printable adhesive. (846 or 842). • Heat press.

  19. Lithographic Transfers How to produce: • Design is printed using standard litho practices. The image should be mirrored to be right reading after application. • 996 inks are printed in the following sequence. Black, Cyan, Magenta and yellow. • Plastisol backing is screen printed over top of the litho ink and gelled through a conveyor dryer. Gelling temperature is 110C (230F). The backing must be applied within 24-72 hours. • Hot melt adhesive powder is applied to wet plastisol before it is gelled or a printable adhesive is screen printed overtop of the backing plastisol and gelled through a conveyor dryer. • To add a puff effect, print 878 puff ink after the plastisol backing but before a printable adhesive. This will give the transfer a raised appearance once applied to textile. • To add a metallic or glitter effect, print 700 series ink after applying the plastisol backing. Leave a “knock out” in the white to create space for the glitter.

  20. CMYK Transfers Screen printed resolution dependant images • Supplies needed: • High pigment load CMYK inks. (Excalibur 600SS series). • First down clear plastisol. (Excalibur 905 or 908). • Coated release paper. (Artsan, T-75 or equivalent). • White or clear printable adhesive. (Excalibur 888 Stretch Back or 846). • Stencils made with fine mesh for CMYK colours. (132-142) • Stencils made with coarse mesh for clear and adhesive. (42-62) • Heat press.

  21. CMYK Transfers Screen printed resolution dependant images • Film output: • 45 to 65 lpi. • Standard offset angles. • Printing: • Gelling between each layer. • First down clear. • Black - Cyan - Magenta - Yellow. • 888 Stretch Back (dark coloured garments) or 846 printable adhesive (white coloured garments)

  22. CMYK TransfersScreen printed resolution dependant images. • Application: • 190C (375F) - 204C (400F) for 6-8 seconds. • Peel paper away while the ink is still hot. • 100% of the ink will release from the paper and transfer to the fabric.

  23. Puff TransfersSpecial effect • Single step process that will allow printers to add a raised effect to certain parts of the design. • Can be added to Screen printed spot colour, CMYK or Litho transfers.

  24. Puff TransfersHow to produce • Print foreground colours with 960 hot peel, 600SS CMYK or 996 litho inks. Gel through conveyor dryer. Print Puff 878 base or white in areas where a raised effect is desired. Gel through a conveyor dryer. application: • 190C (375F) - 204C (400F) for 6-8 seconds. • Peel paper away while the ink is still hot.

  25. PVC Free Transfers A new standard for safety • Reasons for PVC free: • Major sportswear brands have specified that any imprints that have “next to skin” contact must not contain any PVC • Tag-less labels have become the standard for athletic wear. • Often contain very small fonts and details which are difficult to print and repeat with PVC free water based products. • Evolution Series II NX system offers an alternative to water based inks.

  26. PVC Free TransfersA new standard for safety • Reasons for PVC free: • Some major sportswear brands have banned the use of PVC in all of their imprints regardless of placement. • Evolution NX Athletic transfer system is a good option for 100% polyester athletic uniforms.

  27. PVC Free Transfers A new standard for safety • Supplies needed: • Evolution Series II NX System inks. • Coated release paper. (Artsan, T-75 or equivalent). • Stencil made with coarse mesh. (30-62T). Finer meshes can be used for fine detailed images. • Hot melt powder adhesive. (H-1). For extremely fine detailed tag less labels H-10 Superfine powder may be required. • Heat press.

  28. PVC Free TransfersA new standard for safety • How to produce: • Printing parameters are the same as plastisol cold peel transfers. There are only 2 differences. • Only H-1 hot melt powder adhesive may be used. There is no printable adhesive available. It is still in development. • Evolution ink must be cured on the paper in between printing colours. The type of plastic used will not remelt in the same way as PVC. In order to achieve maximum wash fastness and opacity the imprints must be cured on the paper. • Application: • 126C (260F) - 137C (280F) for 10-15 seconds. • Peel paper away once the ink has fully cooled. • 100% of the ink will release from the paper and transfer to the fabric.
