Flatbed scanner for tabloid

The person who must deal with a variety of media techniques accurate equipment is a must. Media would usually include film and photos. An essential piece of technology is the scanner. It must be as versatile as possible. The ability to scan a variety of thicknesses and sizes is a timesaver. The best scanners are used for the tiniest objects the size of stamps all the way through to huge blueprints and plans. There are a variety of flatbed scanners for tabloid purposes. The first considerations should be those of color pass and bit depth.

The scanners of the past were limited in that they only confined three passes. Older models were very slow in capturing colors from an image. The only color range then was red, blue and green or RGB. There were 24 bit and 36 bit scanners. These were capable of giving 68.7 billions in color. These have been overtaken by the 48 bit scanner. This scanner is regarded as producing colors that are the most lifelike. This piece of technology is so efficient it captures 250 trillion colors if necessary. Even the human eye is incapable of picking up so many.

There are two kinds of image sensors in flatbed scanners for tabloid. These are the CCD or the CIS. CCD stands for charge-coupled device. It makes use of lenses and mirrors. Reflected light is redirected from a document to the CCD. Because of this sensitive and complicated technology a CCD flatbed scanner is the most expensive. It must be noted that this scanner is also larger and heavier. However, for the purposes of tabloid this scanner is capable of producing superior quality. This scanner is highly suitable for desktop or any other specialized publishing purposes.

A CIS or contact image sensor scanner may be the answer for smaller businesses. In this scanner the sensor captures directly reflected light. This is the reason for it being placed just beneath the scanner bed. This flatbed scanner for tabloid is a lot cheaper. There are portable models because they are so compact and lightweight. Flatbed scanners are able to deliver the following features:

* Flexibility
* Usability
* Quality

A flatbed scanner requires the image to be placed face down on the glass pane. There is a cover that can be lowered to protect it from ambient light. The sensor moves across the glass pane to read the image. Special accessories are needed to scan transparent images. A flatbed is regarded as a cost effective means of getting good quality images.

  1. Thanks for some great info. After years of service, my Linotype Hell Jade 2 has given up the ghost; and I’m in the market for an affordable (300 US, 200 Euro) flatbed scanner that can accommodate 11 x 17 originals. I’ve read so many reviews — and been flabbergasted by some prices — that I now have no idea what to buy. On top of that I use a Mac (OSX), which apparently is a bigger issue than I thought. Do you have any recommendations?

    Thanks for any insights.
