Digital Printing ppt by Sukhvir Sabharwal
Digital printing is a relatively new technology that uses inkjet printing to apply colorants directly onto fabric. It allows any design to be printed on fabrics like cotton, polyester, and silk. Before digital printing, fabrics must be pre-treated with chemicals to prepare them. During the process, fabric is fed through the printer and ink is applied in tiny droplets. It is then cured through heat and the printed fabric is washed and dried. Digital printing enables continuous-tone images and printing to edges but has higher costs for sampling and shorter runs due to the slow printing speed.
Burn-out printing
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.
Transfer Printing
A brief discussion on transfer printing in textile industry with its different types of application method.
Raising Finishing
Raising is a mechanical process that uses revolving cylinders covered with metal points or abrasives to stand up the surface fibers of a fabric, creating a lofty texture. It is done on wet wool or dry cotton fabrics. Raising is used to create effects such as pile, fleece, peach skin, and a warmer, softer hand. There are two main types of raising machines - teasel raising machines and card wire raising machines. The two primary types of raising are napping, which uses metal wires to dig out fibers and create higher pile, and sueding, which uses abrasives like sandpaper for a lower, suede-like pile typically on silk fabrics.
Printing
This document provides information about various printing methods and processes. It begins by describing direct printing, resist printing, and discharge printing methods. It then discusses different types of printing methods known, including screen printing, and provides steps for processes like design to screen and after production primary printing inspection. The document also includes descriptions of specific printing techniques like roller printing, block printing, dye sublimation printing, and heat transfer printing. It concludes by comparing automatic print versus hand print.
Dyeing machineries
The document discusses various dyeing machineries used for different textile materials. It describes batchwise and continuous dyeing processes and the advantages and disadvantages of each. It provides details on loose stock, yarn, fabric and garment dyeing machines including jigger, winch, jet, padding mangle, and beam dyeing machines. Beam dyeing machines allow for high temperature, high pressure dyeing with short dyeing times and high dye exhaustion while delicate fabrics are better suited for beam dyeing machines with lower production rates.
Digital printing
Digital inkjet printing allows designs to be printed directly onto fabrics from a computer without additional efforts like traditional printing. It has emerged as a flexible printing technique since the 1990s. Key benefits include quick design changes and mass customization capabilities. Various digital printing technologies exist, like DOD inkjet which only deposits ink where needed, and piezoelectric inkjet which uses electrostatic forces to spray micro ink droplets. Software programs help manage color and translate designs for printing. Digital printing is growing and offers opportunities in new applications and markets due to advantages in speed, cost, design flexibility and environmental friendliness over traditional textile printing.
Comparing rolar and rotary printing
Rotary and roller printing are two methods of textile printing. Roller printing involves engraving designs onto copper rollers and printing one color at a time onto fabric using pressure. Rotary printing uses perforated cylinders or screens to print designs continuously onto fabric using paste that passes through the perforations. Rotary printing allows for larger designs, more colors, and fresher designs compared to roller printing. Both methods have advantages like production levels but rotary printing provides higher quality and larger scale printing capabilities.

Textile printing
Direct printing is the most common method of applying color patterns to fabric. It involves applying dye directly to the fabric in paste form using block printing, screen printing, or roller printing. Discharge printing applies color to the entire fabric first and then removes color in certain areas to create a pattern. Resist printing involves applying a paste that resists dye to the fabric before dyeing it, so the pattern areas are not colored.
Styles of printing
1. Textile printing involves applying colored patterns and designs to fabric using thickened print pastes containing dyes or pigments.
2. There are several styles of printing including direct, discharge, and resist printing. Direct printing applies color directly to fabric while discharge and resist involve removing or preventing color fixation in certain areas.
3. The printing process typically involves color paste preparation, printing the fabric, fixation with steam or heat, and after-treatment including washing. Alternative techniques to printing include embroidery, knitting with colored yarns, and applique.
Digital Textile printing
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.
Beam dyeing machine
Beam dyeing is simply a much larger version of package dyeing.
This method is similar to package dyeing but is more economical.Yarn is wound on to a perforated warp beam or perforated cylinders
Scouring
Scouring is the process of removing natural and added impurities from textiles using alkali solutions. It makes fabrics hydrophilic and absorbent. There are two main methods - batch/discontinuous scouring using kier boilers, and continuous scouring using J-boxes. Key steps involve saponification of oils and emulsification of waxes. Souring neutralizes residual alkali on scoured fabrics using acids.
Burn-out printing
I will introduce yours with a rare, critical and costly print. The name of this print is “Burnout print”. This is a rare quality print. Burnout print is also very expensive too. It's a very nice quality print.
Printing
Printing techniques were summarized including:
1. Printing involves applying dyes or pigments locally to fabrics to create designs through techniques like screen printing and block printing.
2. Screen printing uses a mesh screen to block ink from transferring in some areas to create sharp-edged images, while block printing carves designs into wooden blocks.
3. Other techniques include discharge printing which dyes the whole fabric and then removes dye in a pattern, and resist printing which applies a dye-repelling substance before dyeing.
Roller printing.
Roller printing is a textile printing technique invented in 1783 that uses engraved copper rollers instead of hand-carved blocks. The design is engraved onto the copper roller, which is then electroplated with chrome for durability. Multiple rollers can be used to print one repeat of a design onto fabric passing over a central cylinder. Defects can occur due to scratches, loose threads, or uneven pressure, but roller printing allows for higher production compared to earlier techniques.

Textile wet processing
Textile wet processing is the process that use in any finishing treatment. Where, this process is applied on textile in form of liquid with involves some for chemical action on the textile.
Examples: bleaching, printing, dyeing and printing.
Introduction to Dyeing and Printing
Color is one of the most significant factors in the appeal and marketability of textile products.
Color can be added to textile objects by either dyes or pigments.
Most colored textiles is achieved by dye or pigment mixtures rather than a single dye or pigment.
Dyeing is a method which imparts beauty to the fabric by applying various colors and their shades.
Dyeing operations are used at various stages of production to add color and intricacy to textiles and increase product value.
It chemically changes a substance so that the reflecting light appears coloured .
The property of color fastness depends upon two factors- selection of proper dye and selection of the method for dyeing the fiber, yarn or fabric.
Dyes are used for coloring the fabrics.
Dyes are molecules which absorb and reflect light at specific wavelengths to give human eyes the sense of color.
There are two major types of dyes - natural and synthetic dyes.
The natural dyes are extracted from natural substances such as plants, animals, or minerals.
Synthetic dyes are made in a laboratory. Chemicals are synthesized for making synthetic dyes. Some of the synthetic dyes contain metals too.
Dyeing processes may take place at any of several stages of the manufacturing process (fibers, yarn, piece-dyeing). Stock dyeing is used to dye fibers.
Top dyeing is used to dye combed wool sliver.
Batik
resist dyeing process- designs - made with wax on a fabric which is subsequently immersed in a dye to absorb the colour on the un-waxed portions - batik dyeing.
done notably in India, Japan and Indonesia.
patterns - geometric, moral, bird or animal motifs.
melted wax mixed with resin - traced on the areas not to dyed with a tjanting- small instrument - short, straight reed handle -attached a small, funnel shaped copper cub with one or more spouts.
After application of wax, the fabric is dipped into dye - particular colour desired.
After dye - fixed - material dried- cloth is boiled and rinsed - remove the wax.
Any traces of wax remaining - scraped off.
primary colours used -red, yellow, blue /blacks and white.
light and dark shades - brown, green, violet, orange and pink - also used.
method light colours - applied first followed by the wax; the deeper shades are then built in.

3D Fabric
3D fabric is fabric constructed with three-dimensional structures rather than flat or two-dimensional fabrics. Special looms are needed to weave 3D fabrics with warp threads at 60 degree angles, but 3Dm fabrics can also be woven on ordinary looms using multiple layers of warp and weft threads. 3Dm fabrics have a minimum of four layers of warp and weft threads stacked on top of each other to provide thickness. The warp threads pass through the layers either straight or at angles to connect the layers and give the fabric three-dimensional qualities rather than being flat.

It explains the purpose and functioning of each machine and shows their effects on fabric properties before and after processing. In the end, the document briefly discusses softening and resin finishing.
Anti shrink finish
Cotton fabric shrinks due to the swelling of cotton fibers in water and the release of mechanical stresses from spinning and weaving. The anti-shrink finishing process uses a sanforizing machine to pre-shrink cotton fabric in a controlled way. The machine places the moistened fabric onto the concave surface of a stretched rubber blanket. As the blanket contracts, the fabric is forced to shrink with it, preventing excessive shrinkage during washing. Key parts of the machine include feed rollers, sprayers, a steaming unit, and a rubber blanket wrapped around a heated cylinder. The amount of shrinkage can be controlled by adjusting the tension on the blanket and its thickness.
Printing Ingredients
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.

Digital fabric printing is a relatively new inkjet printing technology that can print any design on fabrics like cotton, silk, and polyester. The process involves pre-treating the fabric, feeding it through a printer that applies tiny ink droplets to form the design, and then curing the ink using steam or heat. Digital fabric printing allows for photographic quality images and unlimited colors to be printed across the entire fabric surface with advantages like lower setup costs for short runs and variable data capability. However, it also has disadvantages like higher costs for larger productions and slower printing speeds compared to traditional fabric printing methods.
Lecture 8 digital printing of textiles (condensed)
Digital printing of textiles allows for mass customization by printing designs directly from digital files without screens or plates. It provides benefits like quick design changes and short runs but adoption has been slow due to limitations in printing speed. Improvements in inkjet printing technology aim to increase speeds to compete with conventional rotary screen printing for bulk production. While digital printing is established for sampling, the future vision is for it to also enable small batch production directly from computer designs.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes.

Digital printing
- 1. Md. Ahad khan 143-32-266
- 3. It is the technology that consists of printing your designs on fabric, directly from your computer, with no other additional step. This means that after you are finished creating your designs, and once you have them in repeat, you can print on fabric just like you print on paper or other medias using a RIP software. Some ink types may require a post treatment such as steaming or heat setting the print.
- 4. Digital can print any design on all kind of fabric, like cotton, poly or silk etc.
- 5. The only requirement is that the fabrics to use have to be pre-treated to hold the ink better, and achieve a wider color gamut and quality output.
- 6. The Dyes which are commonly used for digital textile inks are as follows: Acid dye Inks, Reactive dye Inks and Disperse dye Inks. Name of Digital Printing Inks Types of fibers used Acid inks Silks & Nylons Disperse inks Polyester Dye based inks Not used for any fabrics, used for photography only. Reactive inks All cellulose based fibers: Cotton, Linen & Rayon
- 7. Pre-setting Process : Using 'pre-setting' system / Coating machine / Padding mangle, appropriate treatment should be done for the fabric before printing. DTP System : Print it via Digital Textile Printer after modifying colors & Designs with help of Design & RIP Software. Finishing Process : Printed result has to undergo the finishing process, such as steaming, washing etc.
- 9. The image can be printed all over the entire item, with no difficulty. Colors can be extraordinarily brilliant due to the bonding of the dye to the transparent fibers of the synthetic fabric. Truly continuous tones can be achieved. Time saving for sampling only. 9sukhvir.sabharwal.tit07@gmail.com
- 10. Back side of fabric always be white. Sampling and production cost is high. Cost and lead time will be high for bigger run. Speed of digital printing is very slow. 10sukhvir.sabharwal.tit07@gmail.com
- 11. The concept of digital printing on fabrics has opened new opportunities for designers, merchandisers, production and art departments, sales persons, etc.
