CIS vs CCD scanner

CIS : Contact Image Sensor Method
CCD : Magnification Optical Method

All Graphtec scanners currently use the CIS sensor system, ensuring sharp, crisp and clear image reproduction. This technical advantage is further reinforced by a very accurate paper feed and hold technology. Even deep wrinkles on paper can be smoothed to provide optimal image reproduction. Graphtec scanners provide stunning high-resolution images compared to other products in the market. Graphtec scanners (CS610/510/CSX300) achieve a wider color gamut using the CIS method instead of the older CCD method. (CS610/510/CSX300) can produce high levels of precision and accuracy, as well as a high Optical Resolution of 600dpi. These are truly state-of-the-art scanners that not only meet the needs of industries requiring precise images such as civil engineering drawings, city planning drawings and apparel paper patterns, but also satisfy the needs of the graphic arts and printing industries.

What is the CIS (Contact Image Sensor) method used in the image scanner?

Image scanners can use one of two methods to scan documents—CIS or CCD.
Graphtec employs the leading-edge CIS method for optical systems in its scanners.
Enabling extremely high-resolution and high-accuracy input with large-format scanners, the CIS (Contact Image Sensor) method is a state-of-the-art scanning technology that uses contact image sensors developed solely by Graphtec.

CCD method (optical reduction method) Light from the light source is reflected by the document’s surface. This reflected light is reflected further by a mirror, directed through a lens, and received by the CCD. Since the CCD reads light reduced by the lens, this method is called the “optical reduction method”.

CIS method (contact image sensor method) The light from the three RGB color LEDs used as light source are reflected by the document. This reflected light is received in turn by the CIS sensor, which performs the actual scanning. The LEDs, lens, and sensor are integrated into a single module. Since these components are all rods of the same length in close contact, this method is called the “contact image sensor” method. This is the method used by Graphtec. This method is ideal for markets that require precision for applications such as civil engineering survey drawings, urban planning drawings, and apparel patterns.

Features of CIS method

Sharp image scanning

All models provide 600dpi optical resolution and 9600 dpi interpolated resolution allowing high-resolution and high-quality scanning.
Further high-resolution and high-quality scanning is enhanced by Graphtec technology that improve contact between document and sensor.

No Warm-up time

The scanner is ready for scanning 10 seconds after power on *1, thus saving energy.

Power save

This feature meets several environmental standards.
P　ower consumption is 5w or less when it is in power save mode.*2

Compact Design

Compact design saves space, operability and resource.

High-speed scan

High-speed is provided with our long-established document feeding technology.

Versatile “Scanning Master 21+” driver software enables a range of scanner and data operations

The Scanning Master 21+ software for scanners provides a wide range of features, including a powerful backup solution for those using scanners. This software converts scanned data into digital data and offers simple data editing and correction functions. Specify scan settings for specific needs.

Simple copy function

Automatic deskewing

Automatic despeckling function

Automatically removes speckles as the document is scanned.
Any speckles below the specified pixel level are removed for monochrome data. For grayscale and color data, the software applies an averaging function to match surrounding colors.

Entire drawing/Detailed drawing function

Entire drawing Displays the entire image in a separate window. This function lets you confirm which part of the image to display.

Detailed drawing Displays a detailed drawing of the image displayed at the current cursor position in a separate window.

Lets you make scan settings/documentspecific scan settings

You can set scanning conditions suitable for different document types (e.g., maps, drawings, or blueprints) in advance to enable easy selection of the most appropriate scanning environment.
Moreover, these conditions can be edited and new scanning conditions added and stored.

Suppressing the background color

To enable scanning, you can adjust White point, Crease reduction threshold level, and Crease reduction intensity values to turn the background of the tracing paper or mylar film white.

Continuous scanning function

Press the scanner Scan key on the main body to enable continuous scanning. File names are automatically numbered and saved sequentially.

Saving scanned data as PDF files

Select the appropriate command from the File menu to save scanned data in PDF file format. This feature enables various data management and application methods.
