Heat Transfer Printing Process On Curtain Or Other Fabric Materials With Consideration Of Quality, Cost And Speed Of The Production


CHAPTER ONE
            1.0     INTRODUCTION
Heat transfer is a process or method of attaching a design made on one surface onto another surface with the aid of heat produced by hot object (pressing iron, hot metal, heat press). It is a process that involves the use of computer and printer to make or create a good design. In other words, heat transfer is a printing process which involves the transferring of image on to substrate with the use of transfer paper already printed on and heat source.
Heat transfer process is a very easy way to print images in multi-colours. The achievement of a good final product in heat transfer are based on choice of substrate (curtain) and the materials involved in the process like;
i.  Software
ii. Computer
iii. Printer
iv. Transfer paper
v.  Iron or flat heat press
vi. Cardboard
 
To achieve heat transfer using home electric iron, we need first to make the design of the image to be printed using a right software today, there are available software for designing of the images, the design will be mirrored (i.e. the image will be reverse) so that it appears correctly on the curtain (substrate). A Formica board is used to transfer the image with the source of electric heat press, the heat press tends to disperse the heat, and the transfer paper needs the heat to hot and work properly.

The curtain is placed on the surface of the Formica board and the area to be printed on facing up the transfer paper is placed on the curtain and a cardboard is placed on it, this board is placed as an intermediary between the transfer paper and the heat press.

1.1 Background of the Study      
A Physist named Leo Greatz invented heat transfer printing in Breslaw in Germany in the year (1856). He started his process with foil printing (hot stamping) using metallic film in a specially printing process that produces shining design on paper, vinyl, textiles, wood, hard plastic, book cover and many other materials. Heat transfer is ideal for small-scale productions when compared to other printing process such as screen printing, lithographic and others.  

1.2 Aims and Objectives of the Study
This study is for the purpose of obtaining an appropriates choice making during   heat transfer printing process on curtain or other fabric materials with consideration of quality, cost and speed of the production.

1.3  Scope of the Study 
This project intends to practically produce print on fabric material (curtain) with heat transfer method of printing.

1.4 Definition of Terms

i. Heat Transfer Printing: This is the process of applying heat-applied materials to various items (i.e. substrates) with a heat press. Heat-applied materials contain a heat sensitive adhesive on one side; when heat is applied by a heat press to the material, the material adheres to the substrate to which it is being applied.

ii. Heat Transfer Paper: This is a specially designed paper that can be digitally printed using inkjet or laser printers and be transferred to a variety of garments, fabrics and other hard surfaces by the use of heat and pressure.

iii.   Heat Press: This is a machine engineered to imprint a design or graphic on a substrate, such as curtain, T-shirt with the application of heat and pressure for a present period of time.

iv.  Iron Transfer: This is the home used electric iron that are used for image transfer.

v.     Software: This is the programme used to direct the operation of a computer as well as documentation giving instructions on how to use them.
