Best Practices for Using
CSI Color Standards
The physical standard CSI
ships are specified to be [within 0.5 DE
CMC (2:1]) of CSI’s Master Electronic Standard,
based on a color difference calculated [using
10 degree observer and the prescribed illuminant]. CSI’s Instruments
have been certified by the manufacturers to be within the close tolerance
specification of their master Instruments, or are profiled using proprietary
software. CSI verifies on a weekly basis the performance of its Instruments to
be within that tolerance level by measurement of a characterized BCRA tile set
or through profiling. CSI stores the
Master Physical Standard flat inside a BHT free plastic bag in a dark area when
not in use.
When color standards are
ordered from Color Solutions International, we recommend that the master .qtx file of the color standard is requested during the
ordering process. Upon payment/completion of the order, the master .qtx file is delivered immediately per e-mail. We recommend
that textile mills/vendors upload this .qtx file in
their color matching software and begin the process of lab-dipping. This
methodology will speed the process of lab-dipping. Once the physical standards
arrive in the mail, the textile mill should visibly check the generated lab dips
from the master .qtx file against the received color
standards. The combination of electronic data and visible evaluation should be
used to determine if a lab-dip is suitable to submit to a Retailer or Brand for
approval.
We do not recommend
that the textile mill/vendor measure the color standards in their color
matching system and compare them to the master .qtx
file. CSI expects that their will be variation between a textile mill/vendor
measured color standard and the master .qtx file in comparision to the readings obtained by Color Solutions
International. From our experience, we have found the following reasons as the
most common for potential deviations.
• The color difference
equation, illuminant or observer selected in the software
• The temperature or
relative humidity of the fabric at the time of measurement
• The way the fabric is
presented to the spectrophotometer
• Condition of the physical
standard (should be stored flat inside a BHT free plastic bag in a dark area
when not in use).
• A Datacolor
SF 600 CT or SF 600X machine or GretagMacbeth
Color-Eye 7000A machine is not used or is not correctly maintained and
functioning to the same certified levels
• The same DataColor ColorTools software or GretagMacbeth Colori QC software is not
used or is not correctly maintained and functioning to the same certified
levels
CSI WARRANTS THAT AT THE TIME CSI SENDS A PHYSICAL STANDARD IT WILL MEET THE MASTER ELECTRONIC STANDARD ESTABLISHED BY CSI UNDER CSI’S PROCEDURES DESCRIBED ABOVE.
