※Tolerance formula : The color tolerance is relatively close to 

    the sample and the known standard color measurement

◆ CIE LAB : Color space is based on a color can not be both

   green and red, nor can both be blue and yellow; this theory

   and established.

※ CIE LAB The tolerance formula is centered on the standard,

    and then gives the individual

      L * a * b * value, plus or minus (+/-) of the error range.

This formula can simply display the color error directly

 △ L*  = L* sample - L * standard (Brightness Difference)

 △ a* = a* sample - a* standard (Red / green difference)

 △ b* = b* sample - b* standard (Yellow / blue difference)

※ CIE LCH:  The tolerance formula is centered on the standard,

    and then gives the individual

    LCH values, plus or minus (+/-) the error range.

◆ CIE LCH : The color model uses the same color space as

   L * a * b * but it uses L: indicates the brightness value

 C : Indicates the saturation value

 H : A columnar coordinate representing the hue angle value.

This formula can clearly analyze the color saturation and

hue error reasons

 △ L *  = L* sample - L* standard (Brightness difference)

 △ C* = C* sample - C* standard (Saturation difference)

 △ H* = 〔(△Eab)  -(△L *)2  -(△C*) 2 〕12  (Hue difference)

※ CMC  The tolerance formula uses the ellipse as the visual

    range of the chromatic aberration,and the result is closer to

    the human eye;Thus many CMC represent the representation

    of the chromatic aberration more accurately than the CIE LAB

    representation.

△ Ecmc  =〔(△L*/ ιSL)²+△Cab */ cSc)²+(△Hab*/ SH)²〕1²

  Use the △ Ecmc formula, according to the type of product,

   set the formula inside the ι and c constant if set ι:

   c = 2: 1 the △ Ecmc error range will be more: ≈:

   c = 1.4: 1 loose when the decision ι and C constant,

   the use of cf value can control the entire range of color

   tolerance, if the larger cf represents the larger tolerance,

   the opposite is smaller on behalf of the tolerance range

   is more stringent.

△ Eab  The tolerance formula is centered on the standard,

   and then draws a sphere tolerance range, the value

   represents the total color difference

△ Eab  = 〔(△L*) +(△a *)2(△b*)2〕12

△ Eab The smaller the value, the smaller the color difference;

   on the contrary, the larger the

△ Eab value represents the larger the chromatic aberration

△ Eab Is also more people use the tolerance formula

Instrument design concept

☆Lightweight, durable, portable spectrophotometer

☆diffusion / 80 (D / 80) Integral optical geometric design

☆Large LCD menu (Menu) mode of operation display to

   facilitate the clear read the results

☆At the same time, the color difference data including

   the mirror and the excluded mirror surface are measured

☆Rugged body design, rechargeable design for easy on-site use

Instrument features

☆Integral ball : Diffuse integral ball with a very stable.

   Durable and highly reflective material(SPECTRALON)

   manufacturing, can withstand the harsh conditions of

   the production environment, to prevent the aging of the

   integral ball wall off and lead to the instrument recession.

☆Any model provides specular exclusion and mirror containing

  analysis function; analysis of color deviation more accurate.

☆SP 64 built-in convertible 4/8 mm measurement target window,

   the user due to measuring the size of the workpiece area, any

   rotation required to measure the aperture, the use of this

   program more efficient and convenient than ever.

☆Through the "project" function to help a number of standard

    colors collected in the same project to do the color standard

     program.

☆Store 1024 standard allowable settings, easy OK / NG

   measurement, red / green LED display and NG sound.

☆Fast color match : Convenient. Time-saving color control data

   measurement, no need to establish tolerance or store data.

☆Can measure the opacity and three colors (apparent. Chroma.

   Three stimulus); more with a dedicated textile 555 color

   classification function, contribute to the plastic. Paint or textile

   ... and other products color quality control.

☆ Poor between instruments : To provide a very consistent

    between the instruments and meters,for the importance

    of more than one instrument color control items.

☆The data can be entered into the X-Rite window color check

    and color matching software.
