ERGONOMIC DESIGN BETA EYE SCAN COLOR BARS
The BETA EYE SCAN CUSTOM GRAY BALANCE COLOR
BAR SYSTEM is designed for faster make ready, precise press
monitoring and quicker turn around using a densitometer for
objective measurements and optical tools for subjective
evaluation. This SEE IT and MEASURE IT system is a precise, cost
effective control system guaranteed to produce the highest quality
printing. The heart of the system is a customized color bar
designed to match the size of your press and numbered ink keys in
exact alignment to the ink keys of the press thereby making faster
and more accurate corrections.
Targets of solid yellow, magenta, cyan, black, and gray balance
appear in every ink zone for ultimate control across the full
width of the sheet. Trapping, dot gain, and resolution targets
are centered for smaller sheets.
CMYK and Gray Balance appear in every ink
zone. 50% and Gray Balance appear every 4th zone
RESOLUTION TARGETS WITH
MICRO DOTS of 1%, 2%, 3%, and
5% minimum printable dot targets
detect press slur and doubling.
Maximum printable dot targets of
95%, 97%, 98% and 99% indicate
press slur, print contrast problems
and/or plate production errors.

The PRESTO SPECTRO is designed to automatically ZERO
to paper and measure DENSITY and DOT GAIN without
changing programs.
The LED will flash when the measurements are GREEN
within TOLERANCE thereby increasing speed and accuracy
of measurements. TOLERANCES can be changed
according to the quality control requirements.
The LED cautions the operator to look at the display RED
and make corrections accordingly.
Color matching with CMYK is simply done in AUTO DENSITY
mode using the MCM (Magic Color Match) feature or in the
new exclusive with Lab COLOR REFERENCE LIBRARY
Delta E that stores up to 32 colors in 4 separate channels
for fast, accurate AUTO color matching. Ideal for Flexo.
To start, open the AUTO MODE screen and Zero to paper.
Measure DENSITY, DOT GAIN and DOT AREA.

DOT GAIN MEASUREMENTS
Dot gain is inherent in the printing process.
It is composed of two components;
MECHANICAL DOT GAIN is the actual physical growth
of the dot on the substrate and varies according to paper
type, slurring, pressure, ink/water balance, etc.
OPTICAL DOT GAIN is the scattering of light within the
substrate which results in a higher than expected dot gain
when measured with a densitometer using the
Murray/Davies equation.
Slur, Doubling or Ink Water Imbalance result in
unexpected DOT GAIN

Note: When measuring DENSITY targets, the measurement
may occasionally show a false Dot Gain in the display. This
is caused by an abnormally low DENSITY target
erroneously interpreted as a high Dot Gain target.
If this occurs, Zero to paper and measure any questionable
DENSITY target again.

OPTIONAL COLOR LIBRARY SOFTWARE
PrestoConnect
Color Library Management Software
The optional
PrestoConnect
Windows software
allows the user to
create, collect, and
manage an unlimited
number of colors in
conjunction with the
new Beta Presto
Spectro portable
spectrodensitometer.
The database organizes the work by Color, Customer, and Job
making it easy for production personnel to use and understand the
system.
Physical samples are measured with the instrument and automatically
written to the database with Lab and Density values, a user-entered color
name, and delta E and density tolerances. A representation of the color is
generated on-screen for confirmation to the operator. Once the sample is
measured the operator has the option to accept the entry, as shown here.
Once the color sample is named and accepted it becomes part of the List
of Colors as shown.

Gray Balance Targets are composed of Yellow, Magenta and
Cyan tints balanced to produce a neutral gray when all the
pre-press conditions are in control.
Making press corrections for slurring, doubling, ink water
imbalance, etc. are fast and easy with ink key adjustments
without stopping the press or wasted paper or downtime.

Trapping is the result of solid yellow, magenta, and cyan
inks printed in two color combinations to produce red,
green and blue solids.
Trapping efficiency is the ability of the second color to be
accepted or trapped by the first color.

Magenta and Yellow)
