This is the first in a 2-part series in which I will be explaining the basics of digitisation. I am assuming no previous experience with any of the hardware of software that will be mentioned.
A Word about Copyright
What you will need
PC / Laptop: In order to run the above software you will need a PC or Laptop running MS Windows XP or newer operating system. Adobe Acrobat is the most demanding piece of software, so you should check the minimum requirements of both the version of Acrobat Writer you purchase and that of the scanner to ensure that your machine is powerful enough to run them.
Scanner: You will require a professional quality flat-bed scanner such as the Canon CanoScan 9000F Color Image Scanner. It is possible to scan material using cheaper scanners, but they are generally much slower and their lamps are not as bright. Using an inferior scanner will increase the length of time spent scanning and result in poorer quality results, especially if the material does not lie completely flat on the scanner platen as in the case of tightly bound journal articles and books. Investing in a good quality scanner will be worth the extra initial cost.
The Scanning Process
1) Running Advanced Tiff Editor
Start the program (with the scanner connected and turned on) and click on the “Acquire” button (it has a picture of a scan on it). This brings up the scanner preview and settings screen. Place the material to be scanned on the platen and click on the “preview” button.
2) Setting scan resolution and colour
Scanning at 300 dpi gives the best balance between image quality and file size. Scan in Black & White unless the bending of the pages means that the text becomes unreadable. In this case Greyscale should be selected, which gives you extra options to improve the image. The increased file size can be reduced using Adobe Acrobat later (see Part 3).
Once you are happy with the settings click the “Scan” button and see what the scan looks like. If it is OK then continue to the next page and repeat until the document is complete.
4) Saving the images
Save the file using a web-safe file name (one that does not have illegal characters like spaces or capital letters). It will save time if you use the same file-name throughout the process, although the extension will change from .tif to .pdf.
In Part 2 I will explain how the scanned image is processed prior to conversion to a PDF file.
