    2. 2. What is Amplify?Colour depth improver of various textilegoods especially dyed with black & darkdyed colours. Produces jet black effecton textile goods.Amplify-BL: for polyesterAmplify-JW & Amplify-ONE: forpolyester ,Cotton & their blendsAmplify-PA For Polyamide
    3. 3. Colour can be broadlydefined as the effect onthe brain of an observerwhen an object isviewed in presence of alight source.
    4. 4. How Is Colour Perceived ?A Light Source
    5. 5. Human Perceive 6 Basic Colours 2 Achromatic Colours WHITE BLACK
    6. 6. Human Perceive 6 Basic Colours 4 Chromatic ColoursBLUE GREEN YELLOW RED
    7. 7. Colours were described by their basic colour terms such asWHITE BLACK BLUE RED GREEN YELLOW
    8. 8. How we select colour deepening auxiliaries What is L*Value?Deep-dyeing auxiliaries should be selected for their L*-valueIn deep black dyeing of polyester, the use of a deep-dyeingagent that improves the L*-value does yield a deeper black,however, according to visual perception assessments fromapparel firms and consumers, the difference is unrecognizableto be casual observer. L*-values easily perceived as jet-black bythe human eye are in the 9.0s. Amplify Series maintains L*-values within that range, producing bluish black shades onpolyester.
    9. 9. Scientific approach towards Quantification of Colours
    10. 10. Simple colours are the proper colours of the elements i.e.Fire, Air, Water and EarthBlack mixed with sunlight and fire turns crimsonAristotle believed Yellow came out of lightness and Blueout of darknessColour Scale75% Light 25% Darkness = Yellow50% Light 50% Darkness = Red25% Light 75% Darkness = Blue
    11. 11. •Fig. 1 L*a* b* color space
    12. 12. •Numbers are more accurate than words atcolor communication•Example) Indication of the color of an apple innumerical figures: L*=42.83, a*=45.04,b*=9.52, Once you learn about hue, lightnessand saturation in color, you might wonder ifthere are more accurate ways of describingcolors other than using words. Quite so. Thesethree attributes of color can be transposed intofigures that indicate human perception. In thisway, anyone can communicate colors throughexpressions common to all. First, let’s look atFig. 1 in which L*, a* and b* coordinates areshown. When indicating a color by figures,lightness is represented by L*, andchromaticity (hue and saturation) by a* andb*. a* and b* each specifies the orientation ofcolor, in terms of Red/Green and Yellow/Bluebalances respectively.The following coordinates indicate the color ofan apple.
    13. 13. Fig 1Now, let us find out what color these coordinatesrepresent. Look at Fig. 2, where the chromaticity of theapple is indicated by point X, where a*(=45.04) andb*(=9.52) cross over. Equally, the tone of color can befound by assigning numerical values along the axes oflightness and saturation in Fig. 3. All of this can besummarized in words as a bright reddish shade.*Accurate figures for Saturation C* can be worked outusing the following formula.
    14. 14. Colour deepening auxiliaries should be selected for their L*-value. L*value represents brightness, and a* and b* value does chromaticity – theorientation of colour, in terms of Red/Green and Yellow/Blue balancesrespectively Fig 2:L*a*b* color space Chromaticity [hue & saturation] The warp axis represents lightness
    15. 15. •Fig. 3 Tone (lightness and saturation)Above Fig shows a cross section (from X) of the diagram in Fig. 2. The warp axis represents lightness.You may also refer to Fig. 1 for a better understanding.*Hue angle H° can be worked out using the following formula.H°=tan-1(b*/a*)
    16. 16. Jet black finish on polyesterL—value above 11 is not perceived as jet-black by the human eye.Good jet black agent should produce L*-value in 9 ~ 10Amplify-ONE/JW produces an astounding Jet black on polyester,L*-value in the 9.0’s Without Amplify With Amplify
    17. 17. Jet black finish on polyesterAmplify-JW & Amplify-ONE are suitable for allpolyester goods which need full blackChador, hijab and other black wearFor polyester, black color goodsProduces jet-black, elegant shadeAlso for deep colors [e.g. deep green, deep navy]
