incorporates the Hue Saturation Value (HSV), also sometimes
known as HLS, colour model and uses three separate colour bars
to visually control the relative amounts of each. The HSV system is
simple to use and it is easy to understand the effect the a change
in any one component will have on the overall colour. In addition
to this, a colour circle is also used to help locate and adjust
a particular shade.
colour coordinates are displayed in both HSV and RGB
colour models (conversion between RGB and HSV is performed automatically).
printer colour match system is also provided using a "colour
library" book printed on your own printer. Each colour
on a library page has a unique Page, Column, and Row number
giving rise to the "PCR" notation used for printer
colours. There is some correlation between PCR and HSV so that a
degree of automatic conversion between the two systems is possible,
although manual fine-tuning of colours may be required.
A separate software
is also available for entering measured CIE colour data from
a spectrophotometer into ScotWeave. This system automatically derives
the screen and printer colours and ensures colour accuracy via a
system of colour calibration for screen and printer.
A ScotWeave Yarn File is a collection of yarn colours that share
the same yarn count value, and may use any of the common count
systems listed below:
Gala, Worsted, Yorkshire Skene, Cotton,
DeciTex, Denier, Wool Run, Linen Lea
Select a count
system to create a yarn file, and then proceed to add yarn shades
to the file using either the HSV or PCR colour systems.
