43 - BRIEF GUIDE TO SCANNING & REPRODUCTION & OPERATION OF CDS . APPENDIX (offre). 8
However for the longer palm-leaves (which are longer than the bed of the scanner) it was necessary to scan each side twice, first one end then the other, a total of four scans. Several leaves were placed on the scanner and the text on the left of the page was scanned first, i.e. the start of the A-side. Then all the palm-leaves were slide horizontally to scan the text on the left of the page, ie, the remaining part of the A-side. An overlapping area in the middle of each left was scanned twice to provide continuity of text (see Figure I overleaf). Next the leaves were all turned over and the process repeated to make two images of the B-side. A total of four images to scan all parts of the longer palm-leaves in one case it was necessary to take three images of each side).
Because of the possibility of confusion all the palm-leaves were renumbered before scanning to ensure that every scanned image contained page numbers and an indication of whether the images were of the A-side or B-side.
HARDWARE USED TO CREATE IMAGES
Processor Pentium P-II 266 MHz Physical memory 262 Mb Scanner Umax Mirage Ilse CD writer Yamaha CRW42601x Printer HP Laserjet 5000
(Any similar IBM compatible should also be able to access the CDs.)
SOFTWARE USED TO CREATE THE IMAGES
Operating system Windows 95 (version 4)
Windows 98 was also tested and worked well Scanner software Magic Scan 4.01 CD writer CeQuadrat WinOnCD 3.50.273(OEM) Image processing Adobe PhotoShop 4.0
There are a number of options in Adobe PhotoShop which allow the production of extremely high quality prints from the scanned images: Greyscale (to reduce the colour images to black and white), Brightness, Contrast, Blur, Noise, Sharpen, Texture etc. can optimize the image before attempting to print.
