1. 1 MD.AZMERI LATIF BEG MSc. in Textile Engineering 2. Textile printing is the process of applying color to fabric in definite patterns or designs. In properly printed fabrics the color is bonded with the fiber, so as to resist washing. Advanced Garment Printing Advancement in technology has paved the way for a much better garment printing. The art of direct printing on garment is simplified by the technology every day. You can already choose and create your own design for t-shirts and other garments regardless of how complex the design is. In this assignment I discuses some advanced garment printing given below. 2 3.

Foil printing, commonly called foil stamping. Foil stamping is a specially printing process that uses heat, pressure, metal dies and foil film Foil printing is to print some pattern with the foil on the fabric for shiny effect. Foil printing is a sublimation transfer printing process. Foil printing is done by the help of paper. Foil paper is solid color, which is made by buyer requirements. Printing is done in high temperature and high pressure. In this process manmade and natural both fabric types can be printed. 5 6. Foil is actually a heat press application, but can be applied on press for certain affects. Foil adheres to plastisol inks or a clear foil adhesive. Available in silver, gold, bronze, red, and blue. There are some awesome iridescent foils affects available too - just check with your sales rep.[1]To get the gold /silver stamp, a foil layer is affixed to a certain material by a heating process. It isnt too complicated of a process and getting the files ready are quite similar to uv-spot printing. See my guide on preparing files for print as a reference and talk with your printer about how to supply the files. Foil printing normally requires vector images and/or outlined fonts of what you want to have stamped. 6 7. In foil printing, the quality of the adhesive is very important. Generally it is made up of acrylic co-polymer with water as diluents. Cheaper qualities show very poor stretch, loss of softness and smoothness after five washes and look very unlike the original print. The foil should not stick to cured inks under pressure. Normally a matting agent is added to avoid sticking.[1] In the second method, printing is done on the foil paper first, and then foil is pressed on the fabric with hot steel roller or iron. Foil paper is called the stamping foil paper. Actually it is not the paper but the detachable foil film on the plastic base. Generally it is PET film of 15 micron thickness, available in widths of 640 or 1500mm 7 8. 8 9. 9 10. 10 11. To produce various attractive design. To produce a shiny and unique look. Long lasting design Directly attach on fabric 11 12. There are twos kind of foil printing method In the first method, the pattern is printed by a foil/transfer adhesive on the fabric, and then pressed with foil paper by hot steel roller. The pressure is generally 5-6 bar on printed portion and at 190 on fusing machine for 8-12 seconds. In foil printing, the quality of the adhesive is very important. Cheaper qualities show very poor stretch, loss of softness and smoothness after five washes and look very unlike the original print. In the second method, printing is done on the foil paper first, and then foil is pressed on the fabric with hot steel roller or iron. Foil paper is called the stamping foil paper. 12 13. Recipe: This is a simple recipe. This can be changed on the depth of the color and types of dyes use. Foil paste-----------90% Fixer --------------- 10% 13 14. 14 So, print your fabric by foil printing process and produce various attractive designs. 15. There are many types of foil colors. But some of them are most common in printing process. Common Foil color list in close-up detail are given below. 15 16. There are two primary types of foil stamping machines. The first type is manual and the second is pneumatic (air powered). Manual foil stampers are ideal for low to medium volume jobs and The pneumatic is ideal for medium to high- volume jobs. 16 17. There are various kinds of foil paper available for use in foil stamping. These are: 17 Metallic Foil Paper: Metallic foil paper has a metal like sheen and gives a shiny and shimmering look to the foil stamped design. Such foil paper is available in different metal shades such as gold, silver, bronze, and copper just to name a few. Gloss Pigment Foil Paper: This type of foil does not have a metallic look but has a very high glossy finish. Using this type of foil gives a painted look to the finished printing. Gloss foil is also available in many different colors 18. Matte Pigment Foil Paper: The same colors that are available in gloss foil paper are also available in a dull finish as opposed to a glossy finish, thus the name matte foil paper. A solid white foil paper also comes under the classification of matte foils. Holographic Foil Paper: A multidimensional image made photographically with the use of lasers and special optics is called a hologram. This kind of foil gives a very special, moving effect to the foil designs. 18 19. 1) Flat Foil Stamping The flat stamp technology is t most popular relatively simple and much more cost effective than the other types of foil stamping. 2) Sculpted Foil Stamping (Multi-Level Foil Stamping) This type of foil stamping gives excellent finished results but is far more costly than regular flat foil stamping. 19 20. 3) Vertical Foil Stamping This kind of foil stamping technology is best used for cylindrical parts, but only to a maximum of 90 degrees of the outer perimeter of such parts. 4) Peripheral Foil Stamping Peripheral foil stamping is the technique used to apply foil heat transfers onto the 360 outer perimeter of various materials. 20 21. Hot foil is economical but very slow. The types of graphics that can be applied are usually limited to text and bold images. Hot foil is not usable with heat-sensitive substrates such as polyethylene, vinyl, or shrink film. 21 22. 22 23. Cold foil ismore convenient and cost- effective than hot stamping. Cold foil printing needs smooth surface substrates for excellent image quality. Uses: household consumables, cigarette cartons, wine labels, and cosmetic packaging etc 23 24. 24 25. From the above discussion we know about the foil printing. Nowadays it is one of the most popular printing process. It gives good and unique design. Thats why its demand is increasing day by day. 25 26. 26
