Color difference at a seam is defined as a Sidematch; the seam is darker on
one side- lighter on the other..
In
manufacturing sidematch problems can occur in tufting, shearing or during
the dyeing process; causing texture, pile height difference or color
variations from side to side in the roll.
Installation Causes:
Reversing the nap of an adjoining breadth, improper pattern match, improper
roll sequence, seam peaking, gaps or overlapped backing at the seam.
Seam
placement is a vital concern when trying to eliminate the potential for
sidematch complaints. Whenever possible seams should be placed where
indirect light does not strike across the seam; seam should run into the
light when possible.
Resolution:
True
color sidematch is often repaired by dyeing (feather blending) the lighter
side of the seam.
Textural difference is often corrected with steaming with vapor steam; not
to be confused with carpet steam cleaning.
Feather blending is typically performed with an air brush or other spray
type equipment. The dye is mixed to match the darker side of the carpet and
sprayed a few feet into the lighter panel. Feather blending permanently
removes the appearance of the dark/light sides, and the visibility of the
seam.
Feather blending and steaming are viable solutions to color and textural
differences at carpet seams.
