CIS VS. CCD SCANNING TECHNOLOGY

Over the last decade, scanning a wide format document has become extremely important as companies are looking to eliminate their flat files and also quickly share plans with a customer or a vendor.  The first consideration is which scanning technology would be best?  There are two different types of scanners – the first is CIS (Contact Imaging Sensor) – this technology features a series of Red, Green and Blue lights that illuminate to capture image data related to each color. The second is CCD (Charged Coupled Device) – this technology utilizes a camera-based form of scanner using a multitude of independent imaging cameras.  Let’s take a look at some of the benefits & differences between these two types of scanning technologies.

  • Cost – CIS scanners have traditionally been less expensive than CCD scanners
  • Quality – CCD scanners are camera-based and tend to generate a higher quality scan, especially for photos & posters
  • Productivity – CCD scanners are usually faster than CIS scanners thus allowing a customer to input more documents per hour than a CIS scanner
  • Reliability – CIS scanners tend to be more reliable than CCD scanners as there is no need for stitching (re-stitching of cameras) which is typically required on CCD scanners when moved

In conclusion, I would recommend a CIS scanner for your everyday CAD/GIS drawings and a CCD scanner for your higher-end color photos, posters & banners.  If you would like more information, do not hesitate to contact Clifford-Wald @ 800-575-1545 or sales@clifford-wald.com.
