Project Title: “Development of appropriate computer aided colour
matching data base and print design library for the use in
production of diversified Jute products”
(JTM R&D Project no. -8 )
Development computer aided colour matching database for
different dye classes to obtain computer assisted dyeing-recipe/
formulation for jute products.
Study of compatibility of mixture of dyes and effect of
different dye bath assistants / auxiliaries on consequent colour
strength and other colour interaction parameters for production
of wash-fast and light-fast dyed jute products.
Organising bulk trial seminars/ workshops / training programmes
at IJT or at factory site to disseminate about this computerised
facility for colour measuring and matching as well as production
of cost effective colour matching recipe for jute based
Development of computer aided print design system using new
generation software system and to utilize the same to develop
novel print designs library for production of attractive jute
based diversified products.
Development of a network between industry and IJT interaction
chain for utilizing the computer aided colour database and
print-design library in effective manner for the common users of
jute sector in association with AJHEEI and others.
Preparation of computer
aided colour matching (CACM) database for different dye
classes(Acid,Direct,Reactive and Vat) to generate computer
assisted dyeing-recipe/ formulation for jute products
Development of a print design library with variation of
design dimension colour combination and replication of print
designs on fabrics for cataloguing of newer jute products
Dissemination of lab. trial results through bulk trial(maximum-two)/
seminar & workshop / hands-on training of jute dyers/ personnel
of jute sector in association with AJHEEI.
Preparation of Shade cards and design portfolio/catalogue for
jute along with colourfastness test results and standardised
Preparation of shade card and Manual on Colour Matching &
3.0 Achievements so far :
Database file for reactive dyes manufactured by Huntsman
dyes of different colour x 9 different % of shades = 108
has been completed. The same for reactive dye manufactured by
International (of 14 colours X 9 depth of shade for each colour
i.e. 14 x 9= 126 shades) has been completed.
Preparation of database file for acid dyes [Dyechem
International] of 10 colours (9 depths of shades for each colour)
i.e. 10 x 9=90 shades has been completed. Acid dyes (Dyestar) of
10 colours (9 depth of shade for each colour) i.e. 10 x 9= 90
Preparation of database file Direct dyes [ATUL] of 17 colours (9
depth of shades for each colour) i.e. 17 x 9=153 shades has been
completed. Direct dyes (Huntsman) of 9 colours (9 depth of shade
for each colour) i.e. 9 x 9= 81 shades has been completed.
Preparation of database file Vat dyes [ATUL] of 7 colours (9
depth of shades for each colour) i.e. 7 x 9=63 shades has been
The Colour fastness (light/ wash/ rubbing) for reactive dyes ,
direct dyes and acid dyes are in progress.
Dyeing process variables study for reactive dyestuff (Dyechem
International), and acid dyestuff (Dyestar International) on
surface colour strength have been done and optimization of
process variables for different colours of reactive dyestuff
(Huntsman International) and acid dyes (Dye-star International)
and direct dyestuffs (Huntsman International and Atul Limited)
is under progress and is almost 85% completed.
About 100 designs have been developed under Photoshop and
50 designs have been developed in computer using Printex (Techman
) software and these designs can be modified /resized /
reduced/ enlarged at customer’s/buyer’s choice / requirements.
Preparation of design catalogue and computerized designs are in
bulk-scale demonstration trial was arranged at Ashim Kar &
Industries Pvt. Ltd. on 28 & 29 September 2010. For field trial
on print design part with our developed designs, we will
organize of the same preferably in September 2011 at the
printing factory of M/s Third Eye Printer at Raja K.L. Goswami
Street, Serampore, Hooghly, as they have agreed for the same and
the second mill trial on comuter aided colour matching system
will be organized at M/s Birla Corporation Ltd.
