This procedure is sometimes referred to as “Burn Out”. A cotton / polyester blended fabric can be printed with a print paste containing the burn out chemicals, and after fixation, the cotton portion is destroyed and only the polyester remains. Burn-out textiles is a technique used to develop raised designs on fabric surface. This is primarily being done in fabrics with at least 2 different fibre content i.e. Cotton-Polyester, Silk-Rayon etc.
Printing means localized application of dyes on the fabric according to design. For printing it is required to produce printing paste. Printing Paste is a viscous paste which is made from pigments, thickeners and many of chemical. A good printing paste is mainly responsible for good printing effect. So it is very important to make a printing paste. There are different types of ingredients are used to make printing paste
Generally following ingredients are used in printing paste:
Dyestuffs or pigment.
Wetting agents.
Thickener.
Solvents dispersing agents.
Defoaming agents.
Oxidizing and reducing agents.
Catalyst and oxygen carrier.
Acid and alkali.
Career and swelling agent.
Miscellaneous agent
Flocking is defined as the application of fine particles to adhesive coated surfaces. Nowadays, this is usually done by the application of a high-voltage electric field. In a flocking machine the "flock" is given a negative charge whilst the substrate is earthed. Flock material flies vertically onto the substrate attaching to previously applied glue.

The process of reproducing digital images on physical surfaces is called Digital Printing. The physical surfaces can be in any form like a common paper, cloth, plastic, a photographic paper, film, etc.
Transfer printing is the term used to describe textile and related printing processes in which the design is first printed on to a flexible non-textile substrate and later transferred by a separate process to a textile.
Sublimation method depends on the use of a volatile dye in the printed design. When the paper is heated the dye is preferentially adsorbed from the vapour phase by the textile material with which the heated paper is held in contact. This is commercially the most important of the transfer-printing methods. Dye sublimation allows photo lab quality picture printing. During the dye sublimation printing process, an image is digitally printed in reverse with dye sublimation toners or inks on to media.

In the apparel industry, besides the artwork to be printed, the most important thing is the printing technique. There are several printing techniques, and each of them is suitable for a certain business strategy. Printing can also be defined as localized dyeing. Defined as the application of dye or pigment in a different pattern on the fabric and by subsequent after treatment of fixing the dye or pigment to get a particular design. Being a designer you may have multiple options to decide which printing techniques is most suitable for a specific design on the garment.
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.Every make a Confusion about printing, i try to make it clear.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Advantages, Disadvantages and Limitations of Transfer Printing
4. Transfer printing is the term used to describe textile and related printing
processes in which the design is first printed on to a flexible non-textile
substrate and later transferred by a separate process to a textile. It may be
asked why this devious route should be chosen instead of directly printing
the fabric. The reasons are largely commercial but, on occasion, technical
as well and are based on the following considerations.
Designs may be printed and stored on a relatively cheap and non-bulky
substrate such as paper, and printed on to the more expensive textile
with rapid response to sales demand.
The production of short-run repeat orders is much easier by transfer
processes than it is by direct printing.
What is Transfer Printing?
5. The design may be applied to the textile with relatively low skill input
and low reject rates.
Stock volume and storage costs are lower when designs are held on
paper rather than on printed textiles.
Certain designs and effects can be produced only by the use of
transfers (particularly on garments or garment panels).
Many complex designs can be produced more easily and accurately on
paper than on textiles.
Most transfer-printing processes enable textile printing to be carried
out using simple, relatively inexpensive equipment with modest space
requirements, without effluent production or any need for washing-off.
6. A great many methods of producing textile transfer prints have been found.
Many of them exist only in patent specifications but several have been
developed to production potential. They may be summarized most
conveniently as below:
Sublimation transfer: This method depends on the use of a volatile
dye in the printed design.
Melt transfer: The design is printed on paper using a waxy ink and a
hot iron applied to its reverse face presses the paper against the fabric.
Film release: This method is similar to melt transfer with a little
difference.
Wet transfer: Dye transfers by diffusion through the aqueous
medium.
Types of Transfer Printing
8. Sublimation is the name for the chemical processes which is a solid
object is changed into gas without first becoming a liquid.
In recent years Sublimation Transfer Printing has become mostly used
and economic printing process. It depends on the usage of a volatile dye
in the printed design. When the paper is heated the dye is preferentially
absorbed from the vapour phase by the textile material with which the
heated paper is held in contact.
What is Sublimation ?
Sublimation Transfer Printing :
9. Dye sublimation is relatively easy way to print design onto garments,
compared to other methods like screen printing, embroidery etc. All
that’s needed is :
1) A dye sublimation printer
2) Sublimation paper
3) Photo processing software
4) A heat transfer press
5) A digital camera or scanner to transfer design
Equipment needed for Sublimation Transfer Printing :
10. 1. Dye sublimation is done using a digital image, a dye sublimation
printer and dye.
2. The image is transferred to dye sublimation paper and the ink is
transferred to the fabric.
3. The image retain the digital quality & is permanently embedded
into the fabric.
4. Then the fabric is washed, dryed and
worn over and over.
How it is done?
11. 1) Work shirts and jackets.
2) Promotional Items.
3) Merchandised for valued customer.
4) T-shirts and hats.
5) Uniform for EMTs, Firefighters, Police and municipalities.
Application :
13. This method has been used since the 19th century to transfer embroidery
designs to fabric. The design is printed on paper using a waxy ink, and a hot iron
applied to its reverse face presses the paper against the fabric.
The ink melts on to the fabric in contact with it. This was the basis of the first
commercially successful transfer process, known as Star printing, developed in
Italy in the late 1940s. It is used in the so-called ‘hot-split’ transfer papers
extensively used today in garment decoration.
What is Melt Transfer Printing?
Melt Transfer Printing
15. The ink layer of the transfer is based on dyes and waxes. The ink layer is
embedded in the fabric by melt and pressure, and part of the ink is
transferred to the fibers and then post-treated according to the
properties of the dye.
When the melting method is employed, a large
pressure is required and the transfer rat of
the dye increases as the pressure is increases.
Melt Transfer Printing Process
17. As the name implies, film release deposits the printed image as a virtually
coherent film on the textile material. Such systems have been used for several
years with great success worldwide for the decoration of garments; their use for
printing continuous web fabrics, which have to meet different criteria, has not
so far proved commercially viable, although the technical problems presented
are well understood.
What is Film Release Printing?
18. This process is similar to melt transfer with the difference that the design is held
in an ink layer which is transferred completely to the textile from a release
paper using heat and pressure. Adhesion forces are developed between the film
and the textile which are stronger than those between the film and the paper.
The process has been developed for the printing of both continuous web and
garment panel units, but is used almost exclusively for the latter purpose. In
commercial importance it is comparable with sublimation transfer printing.
Film Release Printing Working Process
20. Two main methods are used for the production of transfers. One method is to
print on to a release paper, usually one that is coated with a Werner complex,
using a semidrying lithographic ink system and then to blotch screen print over
the image using a white or grey plastisol backing coat. Alternatively the image
can be directly printed using fine screens and plastisol process inks. The image
layer is thin and does not have high covering power, so an additional plastisol
backing layer is normally required. Both methods enable images of high
photographic quality to be produced.
Film Release Printing Methods:
22. Water-soluble dyes are incorporated
into a printing ink which is used to
produce a design on paper.
The design is transferred to a
moistened textile using carefully
regulated contact pressure.
The dye transfers by diffusion
through the aqueous medium.
What is Wet Transfer Printing?
24. Steps of Wet Transfer Printing Process
A wet transfer printing process for fabrics is known which comprises the
following three stages.
1st: The pattern / design is printed on a special grade paper by paper
printing or modified textile printing machine
2nd : The fabric is impregnated with a mixture containing water, dye carrier,
dye fixation, catalyst etc. at the boiling temperature of the bath.
3rd: The transfer of printed design/ pattern from the paper to textile
substrate is effected by forming a sandwich of printed paper and
impregnated wet fabric followed by application of required pressure and
temperature for a fixed time of contact in suitable Machine Specially
developed for this purpose.
26. The capital cost of the equipment is low.
Space required is also small.
A skill printer is not required through careful control of temperature and
pressure.
A clear and sharp definition of all objects is possible.
The proportion of sub-standard quantity is as low as 20%
Since the printed fabric does not required any after treatment, it does not
contribute to water pollution problem.
Advantages of Transfer Printing
27. It gives good prints on well prepared knitted goods.
No adverse effect on fabric’s feel and luster.
It allows excellent dye penetration into the fiber ( because transfer takes
place at very high temperature).
Steaming, Washing, drying etc are not necessary.
Quicker reaction to changes in fashions.
Advantages of Transfer Printing
28. There is some restriction of the production of deep shade
High temp and pressure is required
Once printed cannot be corrected
Only limited dyestuff can be used for transfer printing
Lower production speed due to existing transfer calendars
Storage of large quantities of paper over prolonged period of time is a risk.
Disadvantages of Transfer Printing
29. Not applicable to all fiber specially which cannot stand under
required temperature and pressure.
The print paper is not available.
Limitations of Transfer Printing
