Novel styles in Printing




To “Decorate” means

•Put ornaments on, make(more)

beautiful by placing ornaments on or

in


“Decorative printing”

To give a mark of distinction to

fabric

Non conventional printing material

Novel ways of application and

fixation

White Printing ( Khadi )

• Typical Recipe –

• TiO2 35 %

• Stock paste 10-12 %

• Fixer 3-1 %

• Note – percentage of TiO2 as per desired results


Coloured Khadi printing

after dissolving in water) • Fixer to be added at time of printing

Cracking Khadi print


Titanium dioxide or Khadi, plain or with colour. The key factor in this is proper selection of binder. The binder film should have proper adhesion to the substrate and at the same time the film should crack uniformly on drying.


Eco Brosso Printing • Burn Out: Usually on

PES/Cotton/viscose blend. A strongly acidic paste Sulphuric acid, Al-sulphate mixtures are used. Dry at 100 C ,cure 120 C and wash – peroxide. The strong acid burns away the cellulose to leave a transparent polyester skeleton

Brosso like Printing (eco brosso)

• Ready to print paste Pidicron Transprint K

• Mixture of specialty polymers imparting semitransparent effect

• Print - Dry -Cure


Flock Printing • Flock Types: Viscose, Nylon ,

Acrylic

• Printing method: All in one Print , spray Flock/ electrostatic m/c, Coat , Flock

• Substrates – PE, Cotton , PV , Nylon , Acrylic

• Wide variety of flock binders for all combinations of substrates and flocking material

• Properties of Flock Binder –

Heavy Tack, Pliability of film, Feel of film


Zari / Glitter Printing

• Uses a coarse reflective glitter to give sparkle effect (Fine powders of Polyester films)

• Printing - Binder 80 % + Zari 20 %

Coat/ print Binder , spray and press Zari

• Print – Dry – Cure


Metal Powder Printing • Similar to pigment but uses

metallic powders

• Commercial Grades available – Mixtures of metallic powders

• Mesh size – 20- 120 ( Suitable for tex printing>60 )

• Critical parameters –

Fastness/ Choking/ Blackening of prints

• Gold Binder 80 %

+ Metal powder 20 %+ Fixer 3 %

• Print – Dry – Cure

• Smooth in texture compared to glitter


Mica ( Pearl ) Printing

• Titanium coated with mica

• Print Paste Recipe –

Pearl Powder 20 %

Binder KPL 60 %

Emulsifier 2 %

Stir mildly , add

Kerosene 18 % under stirrer

Fixer - 3 % at the time of printing.Print – Dry – Cure

• Pigment dispersion may be added to above to get coloured Pearl


Foam, Puff , Printing

• Foam/ raise – Based on “Expand / blow “ chemicals

• Each commercial grade specify “ Blow temp “ which is normally between 100-140 C. This temp is critical for the effect

• Ready to use products

• Popular In-house recipe used by Mumbai printers –

Binder 9400 60 %

Foam Powder 15 %

PVAc emulsion 25 %

Dilution to desired levels possible with water based paste or with white khadi


Plastisol Printing

• Bright, soft, stretchable prints on dark dyed fabrics

• Typical Composition

TiO2 or similar Opaque material

High performance Binder

Elasticized homo-polymer of PVAC or PVC

Additives for Gloss/Matt/raise/shine /softness

• Aqueous - Print -Dry-Cure

Binder + Pigment emulsion

• Oil Based - Each colour needs intermediate flash curing


Foil Printing • Adhesive printed on to the fabric, then

silver/gold coated polyester foil is pressed against the adhesives

• Thickness - 15 microns, width 60-1500mm

• Print with Binder . Dry. Foil (Printed cloth and foil passed through hot rolls). Cure(fusing 190 deg C 8-12 sec

• Binder- Excellent adhesion bonding fabric and foil, Regenerates tack when passed through hot rolls. Very soft handle despite high tack. High coverage , “ No Blind spots “

Types of foil

• Metallic Foil Paper: Metallic foil paper has a metal like sheen and gives ashiny 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. In addition to metallic colors, metallic foil paper is also available in other colors such as green, blue, red, orange, yellow, and pink.

• Gloss Pigment Foil Paper: This type of foil does not have a metallic look but has a very high glossy finish. Gives a painted look.foil is also available in many different colors.

• 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

• • Holographic Foil Paper: A multidimensional image made photographically with the use of lasers and special optics is called a hologram. Such hologram images are transferred on unique foil paper, which is then known as holographic foil paper. Foil design gives very special, moving effect to the foil designs.



Bead Printing • Type of Beads –

Plastic chips,Glass beads / balls,Metallic beads/ balls (golden, silver,copper),Mirrors, Natural objects like coir balls

Bead Binder - Suitable for fixation of most of beads

• Application - Print Binder ,Pour Beads ,Press , Cure


Dew Drop or Shabnam Printing • “ Three dimensional transparent droplets ” on fabric

• Application – Screens 200 microns thick

“ Deep Engraved rolls ”

“ Droplet injecting m/c ”

• Resin should be, fast drying, Non spreading

Non brittle & elastic

Suede Print

• Milky “suede additive”

• Normally 50% additive to plastisol paste. colour could be additional

• “Leathery print” feel


Silicone Print • The new inks enable screen printers to

produce durable, high-quality screen printing that looks great, feels soft, and is wash resistant. The ink has high elongation (good stretch and recovery properties), so it is well suited for use on fabric with 15-20 percent spandex content.

• Traditional inks can require 12-15 layers to achieve optimal coverage. Screen printers can achieve the same effect with only three layers of the new silicone inks. The result is a less bulky finish, lower material usage, faster production cycles, and labor cost savings.


Gel-High density


• Unique thick prints on substrate, resulting in a raised 3D effect • effect of screen preparation, mesh, thickness, number of coats and special ink • small portion of total print design

Cmyk photographic print


• Four colour

printing of small

dots side by side

• Special screens

Smog Printing


In this Smog Transfer process, the

adhesive is applied on the fabric by means

of engraved design roll. In this process, the

foil gets transferred on the fabric through

thermal pressure.

This particular process is used for textiles

as in sarees, dress materials, garments

etc. In addition it can be used for

enhancing purses, presentation paper,

jewellery cases, book covers, paper

folders, decorative materials and pandal

decoration.

Sticker Print


• Ready to transfer print

• Printed design on

paper transferred by

fusing

• Except fusing machine

nothing else required


Combo styles

• Foam + Pearl+ glitter

• Foam + foil

• Dew drop + Foil

• Dew drop + Pearl

• Dew drop + gold

• Gold+ Foam+ foil

• High desity

• Smog

• Flock with + digital

• etc


Novel printing -Future trends

• Fabric to fabric adhesion • PVC printed sheets fused to fabrics •Transfer of labels from paper to cloth • Heat embossing • Photo & Thermo sensitive prints • Lazer cut /prints

• Your Imagination
