Color Dropout

Color dropout is a scanning feature that, as

the name suggests, removes a specific

color from a scanned image. Color dropout

can be carried out either at the hardware

before data transmission or on the desktop

using software after data transmission. The

benefit of performing color dropout at the

device stage is that the bandwidth associated with the file

decreases dramatically due to the removal of much of the

image data. This bandwidth reduction puts less strain on

the network and can have a marked effect on the data

transmission speed and time to file availability.

Who Uses Color Dropout?

In short, anyone who processes forms will probably bene-

fit from color dropout technology: financial institutions

processing loan applications, insurance companies proc-

essing insurance claims, law firms removing highlighting

from discovery documents, government departments

processing tax rebates, immigration requests, grant sub-

missions, schools processing bubble sheet test sheets,

and others.

Forms often incorporate a background color within their

design to allow for easier navigation and improved com-

pletion accuracy. While the use of color makes

forms easier to read and complete, it adds an additional

burden when scanning the results into the business proc-

ess automation system used to analyze the completed

forms. The data found within the forms only needs to be

collected in black and white through processing by OCR

(optical character recognition) or ICR (intelligent charac-

ter recognition) software.

From that point on, the form is converted into binary data

and routed to a database or document management sys-

tem where it becomes part of the electronic workflow.

Rival MFPs can offer 2-bit or 8-bit monochrome scanning

which reduces the bandwidth associated with color scan-

ning, but the color data is still present in the document

just in monochrome format. This means that, at the least,

the file size is going to be greater, increasing transmis-

sion time and storage space. It can also mean that docu-

ments are more difficult to process, especially if the col-

ored area is actually written over.

Scan

Left: Original form with color background for easier navigation.

Middle: Form scanned in monochrome mode without color dropout is hard

to read and prone to image capture errors.

Right: Form scanned using Color Dropout mode is easy to read and deliv-

ers high image capture accuracy.

Left: Original document with highlighting

Middle: Original scanned in monochrome mode results in highlighted areas

being unreadable

Right: Original scanned with color dropout renders the document instantly

usable with no human intervention required.

Color Dropout Productivity

In theory, color dropout could have an impact in two areas

of scanning: the scanning speed and the overall time to get

the color removed before data transmission can begin.

BERTL tested this on the Savin C2525 by scanning 50

pages of a completed, standard tax form, running the same

job in both monochrome text mode and color dropout mode.

We were pleasantly surprised to find that there was no slow

down in the scanning speed when color dropout was ap-

plied. This means that the process will not be adding to the

cost burden of the company in terms of human intervention

time. We were even more pleasantly surprised to see that

the data transmission time dropped 30 percent when we

applied color dropout and resulted in a bandwidth reduction

of 42 percent.

While these figures will obviously change from form to form,

depending upon the level of color dropout out, these figures

are a guide to the potential time and bandwidth savings that

a company can realize.
