State of Art (1)• Worldwide Print Production
Source: Stork Textile Printing Group, Developments in the Textile Printing Industry , 2002.
20+ Million linear meters per year
State of Art (2)• ITMA 2003 - Introductions of Production Inkjet Printers• Dupont, Konica / Minolta, Kornit, Osiris, Mimaki, Mutoh,
Reggiani, Robustelli, Shima-seiki, etc.
State of Art (3)
• Globalization1. Global Outsourcing - smaller community2. Global Information Access - high speed internet / search engine
Design Development, Workflow, Supply Chaining, as well asScience and Engineering.
3. Global Skills - development of PC and graphic softwareWindows 95, PowerMac, Photoshop 3.5, ICC, Apple ColorSync after 1995.
Adobe Photoshop, Illustrator - pen and pencil in design.
Competitive Key Factorsof
Innovative Product Development
1. Cost reductions2. Rapid market responsiveness3. Capacity for design creativity
1. Cost Reduction
• Short to medium run with Digital Textile Printing• Sustainability
Lack of excess inventory (screens and colorations)Less effluents
• Engineering after ITMA 2003Refinement of digital printing technologyAssurance of printingUpgrading printing speed
• Demand - Supply principalMore demand of technology - reduced the cost of technology
2. Rapid Market Responsiveness
• Traditional manufacturingDigital strike-off workflowDigital production workflow
• Alternative manufacturingMass CustomizationPersonalization
Market TrendsSKUs changes more rapidly over shorter seasons.Much shorter product lifetime.
Digital Strike-off / Production Workflow
• Most popular use of digital printing technology today.• Market testing - Engraving - Conventional production printing.• Market testing - Digital production printing.• Reduce S/O (sampling) time and engraving cost.• Quick response to the market.• Simulation of conventional printing looks ---- digital S/O
(color separations, penetration, hands, etc.)• Precise color matching.• Digital S/O is a part of design development processes. (designers responsibility)
Most designs are still done by hands-on.Requires color separation to retain good image quality.

Color separation
• Bit map based rastercolor separation.
• Similar to conventionalengraving separation.
Alternative ManufacturingMass Customization with digital printing
• To provide maximum desired choices of the products• To create seamless digital automation (order-to-delivery)• To establish seamless digital supply chains
3. Capacity for design creativityImportant niche factor for the success after ITMA2003
Reasons1. Aesthetic Movement (US)2. Design Products in Global Market
Critical issue:Global information access / skills - presentable designs.
New Styles of Designfor
New Digital Printing Technology
Elevation of Aesthetic Consciousness• Apple: Reinvention of computer: gray-box - - iMac -- iPod
• Home improvement shows - UK, US.(Trading space, Changing rooms, Crib crashers, etc.)
• Designers Products for middle end (to lower) to the market.Martha Stewart - Kmart, Michael Graves, Issac Mizrahi - Target,WalMart in Vogue.
Global Culture / Market / Design ??• A majority of design products are regional to their cultures.
Success of the printed design products =Aesthetic design variables + External factors + Functionality factors
Success of the printed design products: sales - publicity
Aesthetic design variables: theme, scale of motifs, color, coverage, tactile, rendering, etc
External factors: culture, price, branding, economy, demographics, marketing, etc.
Functionality factors: printing speed, functional colorants, finishing, materials, etc.
• Conceptual design process is the last element to be out sourced.Innovative Designs require cultural maturity.
New Design Stylesas a competitive edge
• Photographic• Diminutive• Unlimited use of color• Simulation• Digital effect• Engineered
No screen - No repeatProcess (hifi) color printing
Into the future
• Neo Cottage Industry• Textile Printing - Surface Printing• Research - Design and Engineering
Neo Cottage Industry
• Paradigm shift of product development
Analog designer - Service Provider - Manufacture - Creative Manufacturee.g. fine art print maker, photographer, etc.
• Increasing numbers of small short to medium run print manufactures.
Textile Printing - Surface Printing
• Printing - Colorants and Substrates(old term: textile printing - localized dyeing)
Universal inkUV curable inkNon-Woven is most growing textile sector (US)
• A key factor for Innovative Product DevelopmentIntegration of Design and Engineering (including Workflow)
• Future Development -more innovative productsUniversal ColorationUniversal Design (algorithm)Specialty Textile Printing (discharge, devore, plisse, etc.)3D Textile PrintingFunctionality of Printing - pre treatment ( with functionalcolorants, anti-UV, anti-microbial, electroconductive-)Integration of Non Woven industry

It is my prediction that digital textileprinting will become a daily commodityafter 5 years just like the development ofthe internet and textile CAD software.All of us involved in this technology willtarget the next engineering challenges.However, until then, we still have muchhome work to do.
