Pk 10 EXTRA SUBLIMATION DISCS FOR Snowflakes (approx 41mm) or use them for practising.... £2.00 Quantity: at £2.00 each Add To Basket You may already know how to sublimate onto metal but if you don't this is one way. Times & Temps may vary according to your heatpress. Remember to remove the clear film before printing!! Print your designs with a 2mm bleed so you get no white edges on the finished key. Lay your sublimation paper with the design facing up and place your discs over the designs and secure with heat resistant tape. Set your heat press for 190 degrees Place your sublimation paper & discs onto the heatpress and cover with blow out paper. The discs should be on top of the paper still. This is fine as metal is a good conductor of heat. Press for 60 seconds. BEWARE!! The metal will be VERY HOT! Remove discs from the paper and using the double sided adhesive tabs provided, stick to your key.
