9 reasons to use a Colortrac scanner instead of a digital camera
If you have been browsing our selection of Colortrac large format scanners, you may have wondered why you necessarily need to invest in such a scanner at all. After all, a digital camera is similarly capable of producing image files from two-dimensional originals for subsequent viewing on a computer or printing.
With cameras also being a lot cheaper than large format scanners, it may seem a foregone conclusion that they are the superior option. However, there are also a number of key differences between the two to take into account.
A large format scanner can produce perfectly contrasted images without the need for special lighting conditions or to be set up in a particular way. When you use a scanner, the image is lit very close to the original for perfectly exposed results and minimal image disturbance from folds or creases. For this reason, far superior image results can be achieved when compared to using a digital camera.
A large format scanner is capable of processing a single A0 document every 12 seconds at 600dpi, compared to the many minutes of preparation that digital cameras typically require.
Using a digital camera to capture a two-dimensional original requires you to lay the original flat or hang it on the wall when compared to feeding through a scanner once only.
The calibration of a large format scanner to provide length accuracy to within 0.1% and line quality to within a pixel enables large format scans to be used for direct estimation work, using the original drawing’s scale. Images that need to be produced to scale cannot be photographed using a digital camera.
Another great benefit of using a large format scanner is its ability to easily process opaque, high gloss and transparent originals – even those mounted on card or board up to 15mm thick using the Colortrac SG scanner. Photographing images using a digital camera that have a gloss finish or are behind glass creates issues with reflective light.
While even the images from high-quality digital cameras can have a resolution as low as 150dpi or less when used for an A0 original, a large format scanner is capable of producing crystal sharp images at up to 600dpi.
You don’t have to worry about your images suffering from lens barrel distortion and warping when they are produced by a large format scanner, whereas camera lens distortion often has to be corrected by those with Photoshop software and expertise in how to use it.
With a large format scanner, 1:1 viewing of your scanned images is possible seconds after the document has been scanned. You can opt for lossless or lossy compression through the scanning software. It takes time to download images taken using a digital camera to view on a computer.
Depending on your specific requirements, you can use a large format scanner to produce colour images in sRGB, Adobe RGB or machine colour spaces. Such colour management benefits can extend to your colour printer if you use the scanner to copy or produce physical hard copies.
