What is Apparel Printing?
Apparel printing is the process of applying designs, patterns, or graphics onto various types of clothing and textiles. This can include T-shirts, hoodies, hats, pants, and other garments. The goal of apparel printing is to create customized and visually appealing clothing items.
Apparel Printing vs Textile Printing
|Application of designs onto finished clothing items
|Includes various fabrics for different purposes beyond just finished garments
|Customization and decoration of ready-made garments
|Encompasses a broader range, including household textiles, industrial fabrics, etc.
|Stage of Production
|After garments are constructed
|Can occur at various stages, including before fabric is cut and sewn into garments
|Specialized in decorating and customizing clothing items
|Similar techniques but applied to rolls or pieces of fabric before garment construction.
|Screen printing, digital printing, embroidery, etc., directly on the garment
|Similar techniques but applied to rolls or pieces of fabric before garment construction
Types of apparel printing:
- Block Printing: Block printing involves using carved wooden blocks to apply ink or dye to fabric. The block is pressed onto the fabric to create a repeated pattern.
- Roller Printing: Roller printing utilizes engraved rollers to apply colour or patterns onto fabric. As the fabric passes through the rollers, the design is transferred.
- Screen Printing: In screen printing, a stencil or screen is used to apply ink onto the fabric. Each colour in the design requires a separate screen, and the ink is pressed through the screen onto the fabric.
- Transfer Printing: Description: Transfer printing involves printing a design onto a special paper or film and then transferring it to the fabric using heat and pressure. This method is versatile and suitable for detailed designs.
- Stencil Printing: Stencil printing involves creating a stencil, which is a template with openings for the desired design. Ink or dye is then applied over the stencil onto the fabric to create the pattern.
- Digital Printing: Digital printing uses specialized inkjet printers to apply ink directly onto the fabric. It is suitable for complex and detailed designs, and each item can have a unique print.
- Batik: Batik is a traditional method where hot wax is applied to fabric in specific areas to resist dye. The fabric is then dyed, and the wax is removed, revealing a pattern.
- Tie and Dye: Tie and dye, also known as shibori, involves tying or binding sections of fabric before applying dye. The tied areas resist the dye, creating unique and often unpredictable patterns.

Difference between dyeing and Printing
|Dyeing in batch-wise continuous/discontinuous
|No difference in color between the face and back of fabric
|Dyeing in batch-wise continuous/discontinuous
|Difference of color between face and back of fabric
|Aqueous dyeing medium of low viscosity is maintained
|High viscous medium of print paste is maintained
|Printing is done in continuous open fabric surface rather than garment form.
|Printing is done in continuous open fabric surface rather than garment form
Print paste forming chemicals:
- Sequestering agent.
- Dispersing / suspension agent.
- Water retaining agent.
- Modifiers etc.
Transfer printing machine
Transfer printing is the term used to describe textile-related printing processes in which the design is first printed on to a flexible nontextile substrate and later transferred by a separate process to a textile.
- Paper selection
- Dye/ink selection
- Paper printing with selected dye
- Fabric preparation
- printing fabric from paper to fabric
The main parts of the printing machine:
- Transfer paper
- Heating element (drum/flatbed)
- Guide r/r
Digital printing machine:
The machine that produces digital images or physical surfaces is called a digital printer, and this process is known as digital printing. The physical surfaces can be in any form like a common paper, cloth, plastic, photographic paper, film, etc. Digital printers directly transfer print onto the fabric by ink. This is the latest development in textile orienting and is expanding very fast.
More recently, high-definition ink-jet printers, used in conjunction with computer-aided design (CAD) software, have become established for preparing pre-production sample prints on textiles. However, a number of wide-format, ink-jet printing m/c together with suitable inks are now being marketed, and these can yield prints of acceptable quality and fastness properties on most textile materials.
The main parts of digital printing machine are as follows:
- Print head
- Inkjet printer
- Control Panel
- Auto feeding
- Alloy gear
- Lead shine motor
- Drying system
General diagram of digital printer:
- Adhesion roller
- Head nozzles
- Belt cleaning device
Advantages of digital printing:
i) Very quick customer response for both strikes off and bulk prints.
ii) Wastage on re-production sampling is minimized.
iii) No capital tied up in the screens, with major savings on storage space.
iv) No. Of colour and sizes of patterns are virtually unlimited.
v) Instant pattern fitting at start-up, minimizing fabric and paste wastage.
vi) Minimal downtime
vii) Only the ink required for design is laid down
viii) The amount of ink pupped to the substrate is far less than that used in a screen printing process
Advantages of transfer printing:
1. Designs may be printed and stored on a relatively cheap and non-bulky substrate like paper
2. Production of short-run repeat orders is much easier
3. Design car can be applied to textiles with relatively low skill and low reject rates
4. Stock volume and storage costs are lower
5. Certain designs and effects can be produced only by use of transfer paper.
6. Enables inexpensive textile equipment with modest space requirements.
