Scanned Material

Brian

Brian

An Old Geezer
Okay, finally looking to start scanning material in my library. Document scanner is the Brother DCP 7020 that can go to 1200x1200 and do color scans with Paperprt 10 document manager. I have the folowing question:

1) File format. Am planning on .pdf; is there something better?
2) Scan: As the documents are a combination of text and graphics, assume I should use the "picture" option for scanning.
3) For servioce manuals, I will use the maximum resolution of 1200x1200 and greyscale to try to get the most detail. Is this the better setup? If I change to "text" I can increase the scan resolution up to 9600x9600. What is the preference?
4) For catalogs, etc is the biggest question. I just tested in "picture' scann at 1200x1200 in 24bit color and the size for the front cover of the Sherwood catalog was 370 megs. I can reduce this significantly by doing 1 or more of several things: 1) go to 256 color or greysacale or 2) reduce the scan from 1200x1200 to 600x600 or event 300x300. If I change to "text" scan I can increase the scan all the way to 9600x9066 for 24bit color but the result is 23gigs for the front page. What combination of scan and color as well as whether it is better to scan in text or picture for brochures is better?

I use the package for office document management so when it comes to these decisions, I'm on thin ice and would like some help from those with experince and those who have used the service manuals from downloads.

Also, once done, where is the better place on the web to upload the files for access?

Yes, for all those who have asked for the Philips Lab Series manuals, I am finally gertting the project started. Sorry for the delay but unavoidable.

Hi Brian

1) PDF is good, it's the standard.

2) Yes picture or graphic

3) 1200dpi might be a little high, 600 for schematics and 300 for everything else.

4) for catalogs/brochures scan at 150dpi 24bit.

File size is very important for the web try to keep them as small as possible, 10 megs is a good general max with approx 30 megs being the biggest most people can download.

I could host those files if it would help.

Have you ever scanned a full page at 9600 x 9600 (!!) and attempted to work with it? :scratch2:

Methinks not, or else you wouldn't even consider it.

Are we talking about making manuals for vintage gear avilable for free download? There are issues here with preservation of the vintage electronics hobby and the availabilty of service manuals that no one seems to consider when putting up bunches of manuals for free download. I've been putting off a lengthy post about it till we moved to the new server...now that that is done I need to do so...shortly.
 
EchoWars firstly, what are you doing up at 4 in the morning? Second, I am looking forward to your take on this long standing issue.

EW, you need more RAM, and few extra hundred gigabytes of drive... :D

Actually the best way to get tiny .pdf files is to set the type, and not just crunch down a scan. Lots more work, but your files will be cleaner, clearer, and smaller - it also lets you bump up the image quality quite a bit for the things that are graphics, without ballooning the file to unmanageable size. A good OCR system is a big help, and something besides MS Office for document layout.
 
If you are going to archive your scans, keep them in an uncompressed format: .tiff or .bmp, etc. They will take up a huge amount of space though. Otherwise .jpg or PDF will suffice knowing that you will have some detail loss.
 
hi brian,

finally gettting around to it huh?that's great.offtopic but when you do get it done and find a place to upload them to online let me know and ill dig out my scanner and do the 3841 and 3881 integrateds for you to add to the site.goodluck:thmbsp:
 
Thanks for the suggestions. I'll try over the next week or so some of the suggestions and variations and see what the results are. Marek, thank you for the offer. Is it best to send you a dvd with the files and have you transfer rather than e-mailing?

Does anyone know of someone who is collecting for public access the original manuals, brochures, etc.? I am thinking that once completed, if I do not have the unit or when something happens to me, I'd like to see the small collection that I still have go somewhere other than the trash bin. Maybe an AK library for posterity or something.

EW, yes, I am looking at the free public access options. I know and appreciate that some are in the business of searching, buying, storing, etc. these and can not reconcile the conflict created between the models other than say that public libraries and book stores have co-existed for many years.
