Re: Using a polarizing filter to suppress glare and lighting reflections?

I typed up a response comprising multiple pages explaining the formulas and examples of how to use them to calculate light and camera distances based on page sizes and platen angles and when I clicked on 'Preview' to check the formatting this POS website took me to the login page and lost all of my...

Re: Flattening a wrinkled page

Nuance Omnipage enhancement tools include a 3D Deskew function which uses a grid that can be adjusted to provide some degree of correction, but at a quick look isn't sophisticated enough to provide full correction. Possibly there are more powerful tools available. Combined with a certain amount of s...

Re: Scan Tailor Advanced

You are asking for PDF input and output functions to be added to ScanTailor, fair enough, but meanwhile there is freeware software that can create a PDF file from a folder of images, and also extract images from a PDF file... Examples are IrfanView (Windows) and XnView MP (cross-platform): both can ...

Re: Fast, Automated and Simple scan routine for single sheets of papers

What you need is a document scanner. This is the fastest way to scan large amounts of loose paper. A good quality scanner with a sheet feeder? That would be fast, and scanning would involve simply pushing a button, or possibly even inserting a sheet into the feeder. The scan files could be set up t...

Re: WTB: Pre-assembled scanner for comic covers

Of the two, the flatbed would probably yield better quality and more even light. While the copy stand would be able to scan more quickly because there is no cover and you don't have to wait for the scanner bar to move back and forth. You are talking very large numbers of magazines now, so that coul...

Re: WTB: Pre-assembled scanner for comic covers

Scanning just the covers would be well suited to a flatbed scanner: while the typical home scanner would be much too slow, a good office multifunction copier-scanner would be very quick and produce quality as high (or low) as you need... And as you are open to paying for the time and labor, in the a...

Re: What is the best free OCR software?

Backstory: I am planning on taking my scanner to the Tulsa Maker Faire in late August. Here at home I use my desk top computer with ABBYY Fine Reader to convert my scans to text. However, I will be taking my lap top to the Faire, and I don't want to buy Fine Reader for the small amount of time I wi...

Re: Scanning larger numbers of 1980's Magazines help

@Steverd Regarding the gutter: Is there actually content you need on the missing edge of the pages? If not, couldn't you resize the page images using software to add [white] canvas so as to match the appearance of the pages? Regarding scanning magazines in general: Are the magazine pages stapled tog...

Re: Two very similar pages, two very different results

Unfortunately I can't upload images to this forum. Why not? You should be able to attach files, and quite large file sizes relative to some forums, using the 'Attachments' tab below, and then optionally display images 'inline' in your posts. However, only certain file formats can be uploaded direct...
