Calibration
Calibration is the
process of setting the scanner device so that it performs in accordance
with an established standard. Its like tuning your piano; making sure it
will output tunes in accordance with the whole orchestra.
A new wide format
scanner may come calibrated from the factory, but as time goes by,
components and lamps will change character and affect color output. With
a Calcomp scanner, your investment is fully protected and your scanner
never suffers degradation, as is the case with other scanner devices with
complicated or missing calibration support.
Calcomp color
scanners are the market's only wide format scanners that can be
user-calibrated to output color in accordance with international color
standards. The unique Precision Color system lets you calibrate in the
field at any time ensuring stabile and predictable color output. Calcomp
scanners are calibrated to both sRGB and NTSC color spaces using an ANSI
IT8 calibration target. |

Matching
High quality color
results in printed copies can only be obtained if the capture device
(scanner) and output device (printer) "see" colors in the same
way on a given media. You can spend a lot of money for raster-image
processor whose job is to ensure color matching and quality from scanner
to printer to media. Calcomp gives you the solution for free in our JETimage
BASE software that is included with every color scanner.
JETimage employs a procedure called "Closed Loop Calibration"
that uses the scanner to gather color information and ensure optimal
color consistency between the scanned original and the printed copy. The
process involves analyzing the correspondence between printed and
scanned values on a set of reference color patches printed on the actual
output media.
Results are stored
in units called "Media Profiles" and each refers to a type of
output media that you use. A number of standard color Media Profiles,
fit to popular printers and printing media are predefined, tested and
installed with the JETimage application. But you can also create your
own Media Profiles and thus add required media types to the list. Guided
by the application, you print the color patches on your printer and then
scan the printed output, automatically generating a Media Profile with
color consistency parameters for the media with the printer. From then
on you just select the profile you need for copying. |

Control
Wide
format color scanning requires high precision capture and full control
over color tones. With our color scanners you can set black-and-white
points and determine RGB tone transfer curves (gamma) to be downloaded
to the scanner. Other color controls include lightness, saturation, RGB
color balance and color blur filters.
Our color scanners
also support Color Management Systems (CMS) by the international
standard ICC profile (Kodak, Agfa, HP, Microsoft, Adobe, etc.) |

Capture
Calcomp Wide Format
Color Scanners incorporate all-digital cameras with advanced
point-of-origin color capture, ensuring low noise and extended dynamic
range. Color is captured at 36 bits for maximum color precision, passing
the best 24 bit of color data to the computer to enhance color fidelity.
Correct colors
depend on good lighting. Calcomp scanners use special color matched
fluorescent lamps - Color Rendering Index (CRI) > 95 for optimal
color fidelity. |
