CMY Balance Tolerance: Used to set the value for the density balance. The value can range from 0.01 to
0.99.
Tone Value Formula: Used to set the tone value formula for dot calculation. The formulas are individually
configurable for C, M, Y, K and Spot Colors. Spot Color Tone Value (SCTV) provides tone values of colors
that correlate well with visual appearance. If a tone ramp is printed with visually equidistant steps the
corresponding SCTV values should have approximately equidistant percentages from 0 to 100%. For the
Murray-Davies formula, the degree of light optical absorption is predefined. For Yule-Nielsen formula, this
can be adapted for different conditions. When Yule-Nielsen formula is selected for the color, you set the
coefficient. Options are: Murray-Davies, Yule-Nielsen, or SCTV (ISO 20654).
Trapping Formula: Used to set the trapping formula for trapping. This function determines how well one
solid ink prints over another solid ink (overprinting). Better coverage ensures a better color gamut. Setting
the color response to Auto mode will operate Trapping with the process inks; use the Spot setting if using
spot colors instead. Options are: Preucil, Brunner, and Ritz.
Paper Indices Functions: Used to select the paper indices that appear after a measurement. Up to four
indices can be selected for the function. Refer below for available options.
Metamerism: Used to set the illuminant/observer combinations for metamerism function measurements. By
determining the metamerism index you define the mutual color modification of two colors when the illuminant
changes. You can set a maximum of three test illuminants.
Color Strength Calculation Method: Used to set the calculation method. Options are: Max. K/S and Mean
xyz. Max K/S is calculated at Point of minimum reflectance in the spectral curve.
Mean xyz calculates color strength by average mean xyz values across the visible spectrum.
Color Strength Colorant: Used to select the type of ink that is used to determine the color strength.
Options are: Transparent ink, Opaque ink or Textile dye.
Reflectance Graph Y Axis Scale: Used to set the Y-Axis scale for reflectance measurements.
Options are: 0..100% and 0..1.
TVI Table Spread: Used to set the TVI Table Spread setting. This is a job function that has a table to view
the TVI (Tone Value Increase, also called dot gain) results of the last tint measurements of a job at once.
Additionally, it shows spread values between the process inks (CMY).
Spread is calculated by subtracting the largest TVI value from the smallest TVI value across the Process
color Inks (CMY) at a given screen % (i.e., 50%). The smaller the spread, the better the gray balance. G7
and PSO differ slightly in how they calculate spread. Options are: Middle and All.
Job Template Settings
These are the settings that were selected for the current job. They are usually locked by the template and
cannot be changed. The parameters include:
Density White Base
Used to set a paper or absolute requirement for various density functions. If you select Minus Paper, as
white base, all subsequent measurements will refer exclusively to the printed ink layer, while the paper
color effect will not be included. If you select Absolute the measurement will also include the paper effect.
To select a paper measurement requirement for all densitometric functions, select Minus Paper. To select
no paper requirements, select Absolute. The functions include Density, All Densities, Density Trend,
Density & L*a*b*, Density & L*C*h°, Hue Error & Grayness, and BestMatch.
Density Status
Used to select the status for all densitometric functions. Options are: ISO Status A, E, I, T, and G.
Density Measurement Condition
Used to select the measurement condition for densitometric (e.g. Density, TVI, Trapping, etc.) functions.
Options are:
M0(No) – No Filter
M1(D50)
