  1. Digital Printing: Mass Customization R.B.Chavan Department ofTextile Technology Indian Institute of Technology Hauz-Khas, New Delhi 110016

  2. Printing Methods • Block Printing • Roller Printing • Screen Printing • Manual • Automatic flat bed • Rotary • Transfer Printing • Inkjet Printing • Methods giving print like effects • Batik Indonesia • Tie-dye India • Spray printing Japan

  3. Approximate period of commercialization

  4. World Production share • Rotary Screen Printing 60% • Automatic Flat Bed 18% • Other methods 22%

  5. Heritage based Technologies • Block Printing • Tie-dye • Batik • Spray/Stencil • Human skill based • Nation’s pride • Non replaceable • Unlimited life

  6. Science based Technologies • Roller printing • Screen printing: Flat bed, Rotary • Transfer printing • Machine based • Replaceable • Limited life

  7. Textile printing methods yet to be commercialized • Inkjet printing • Xerox printing

  8. Present Trend • Demand Activated Manufacturing Architecht • Just in Time sales and marketing concepts • The textile printing must respond to the delivery of high quality fashion designs with wide range of colour combinations in extremely short time • The process must be eco-friendly

  9. Rotary screen printing status • Although Rotary screen printing machines are most suited for production runs they are not ideal to meet the requirements of Demand activated manufacturing architecht and just in time concepts

  10. Situation prior to 1980 Total Manual approach, Time scale 3-12 weeks

  11. Present Situation • Design input • Computer scanning • Computer aided colour separation • Computer aided choice of colour combination • Computer print out of design on paper • Customer approval • Laser engraving of screens • Samole printing • Production printing • Time scale 2-4 weeks

  12. Limitations of Rotary screen printing • Long process set up time for colour and pattern change • Screen production is slow and expensive • Screens require considerable storage space • Does not meet the requirement of Demand Activated Manufacturing Architect and Just in Time concepts

  13. Need for New Technology • New Technology for fabric printing is needed that will permit • Frequent design and colour changes with minimum down time • Computer storage of design information • Inkjet and xerography printing have potential of meeting these requirements

  14. Present Development

  15. Future Development • With the current speed of technology advancement the use of inkjet printing will not only be restricted to sample printing. Further into future lie the prospects of semi-bulk production and eventually full scale production and thus replacing Rotary screen printing technology

  16. Future Development • It is envisaged that a customer instead of purchasing a printed fabric available in the stores • View the design collections on computer • Select the design and colour combination OR • Create new design • Load the information to the printer • Get printed length of fabric with design of choice
