Excalibur’s Lithographic Transfer System consists of four lithographic ink colours (996PF) that can be printed on lithographic presses allowing printers the ability to produce high-speed and finely detailed designs on lithographic presses. After the litho inks have been printed they must be backed with the appropriate Litho Back-up Plastisol to be transferred to the garment. 554PF Clear is utilized on white fabrics where opacity or bleed-resistance is not an issue. Transfers for garments of any colour made of 100% cotton can be backed with 555PF White to ensure opacity. 556PF Low-Bleed White backs up the ink and provides opacity as well as fighting bleed resistance on poly/cotton/blends.
FEATURES AND BENEFITS
- Lithographic inks prints easily on sheet fed presses and dampening systems offering high-production and fine detailed transfers.
- Three choices of back-up plastisols giving printers a choice of colours as well as blends for finished garments.
- Prints easily on G-97 Glitter Transfer Paper to produce brilliant, sparkle special-effects prints.
- Completely phthalate-free and lead-free formulation complies with all standards of Consumer Product Safety Improvement Act (CPSIA) banning phthalates and heavy metals in textile-printing inks.
Printing Procedures for 996PF Litho Inks
Standard lithographic printing procedures utilizing conventional sheet-fed presses or dampening systems should be utilized. The designer has the latitude of choosing single colour, two colour, three colour or four-colour process for the design. In the case of four colour process printing best results are achieved by printing black first, red or blue either second or third and yellow last. Inks allowed to set overnight may show signs of picking and poor trapping when subsequent litho ink colours are printed on top.
Transfer Paper—Best results are achieved by using Transfert 75 release paper or an equivalent. If Excalibur’s 900 Series Glitter Inks are to be incorporated into the design, G-97 Glitter Transfer Paper must be used to obtain proper release of glitter inks from paper.
Printing Procedures for 554PF, 555PF and 556PF Litho Transfer Back-up Plastisols
After the 996PF Litho Transfer Inks have been printed on the release paper the Litho Transfer Back-up Plastisols must be printed within 72 hours.
Mesh: 554PF Clear Back-up Plastisol 110/inch (43Tcm), 555PF White Back-up Plastisol 110/inch (43Tc/m), 556PF Low-Bleed White Back-up Plastisol 80-110/inch (32T-43T c/m). For glitter inks (particle size .008”x.008”) mesh sizes of 24-30/inch (10T-12T) produces the most sparkling effects.
Stencil: Any stencil compatible with plastisol inks may be used.
Modification: Because plastisol inks are thixotropic and can body up during storage always stir ink thoroughly prior to print or adding reducers. If necessary 501PF Curable Reducer may be added increase printability of ink and to help clean from the screen. CAUTION: Adding too much 501PF Curable Reducer will reduce opacity and bleed-resistance.
Squeegee: 70 durometer or 90/70/90 triple durometer blades are recommended.
Gel Temperature: 554PF, 555PF and 556PF gel when the entire ink film reaches 240° F/120° C. Do not over gel back-up plastisols as this will result in poor release of ink from paper and adhesion to garment.
Testing for Proper Gel—After plastisols has completely cooled, peel the plastisols backing from the release paper and stretch. If the plastisols back barely stretches and then breaks it is gelled correctly. If the ink easily stretches and does not break it is probably over-gelled and will not transfer and wash well.
Transferring to Garments—Transfer using standard heat press at 350°-375° F (177°-191° C) for 10-15 seconds at medium pressure.
Clean-up: Use Enviro Series 2000 Green or Enviro Series TR Blend.
Colours: Process Yellow, Process Blue, Process Red, Process Black, Litho Back-up Clear, Litho Back-up White, Litho Back-up Low-Bleed White.
Always test finished prints for gel, curing, adhesion and desired look prior to beginning full production runs. Lancer Group International cannot guarantee the results or back claims that this mixed ink will test phthalate-free if any additive other than an additive manufactured by Lancer Group International is used to modify this ink. Test results by a third-party laboratory verifying all components used to produce this ink are phthalate-free and lead-free are available upon request.
