Hi!
In hopes of stimulating more conversations around banknotes collecting and trying to help others im writing this article. I hope you find it helpfull.
I thought I would share not only my process but also the optimization of the actually scanner settings I use so you can get the most out of you're scanner when scanning you're banknotes. Allot of you guys or gals will know this but im really hoping to help those that are new to scanning banknotes or just need some help on the subject. Ive seen some really old threads on the topic but most dont go into this kind of detail.
If you currently dont own a scanner they can be bought through Amazon for under $100 tax and shipping included. They are a really nice addition to the tools we use. Its nice to have a digital catalogue of you're personal collection. If you optimize you're scanner the right way you can also enjoy the finer details of you're banknotes without straining you're eyes. I would also suggest google photo as a means for storing and accessing you're library. Its private nobody can see you're collection but it can be accessed while you are on vacation on the road, at work or virtually anywhere on the planet with an internet connection and its free! Now onto the good stuff!
This is quite straightforward, but often when scanning banknotes people sometimes settle for the factory settings and sometimes you get good results and most of the times you dont! But if you dig a little deeper there are settings that you can choose to get those nice rich and detailed banknotes to sparkle when viewing them digitally. I have seen some pretty horrendous scan's over the years lets see if we can help fix that.
First things first. Make Sure you're banknote holder (if they are graded notes) are clean from dirt and dust. Secondly the glass surface of you're scanner should be clean and streak free. Use eye glass cleaner or windex with a dust free type cloth. Ive noticed especially on my scanner that over the years the glass on the inside of the scanner has become dirty. You can open you're scanner and clean this also. It will make a huge difference and there are tutorials online. I recently cleaned my scanner inside and out and all it took was a screw driver, windex a cloth and about 10 minutes.
The settings
There are really only a few settings that you should be considering when trying to get the most out of you're scanner.
1. DPI or Dots Per Inch. Generally speaking 300dpi is the main setting on almost all scanners. This is the first setting I would change. I would scan at 600dpi minimum. This will make you're files a little larger but you will get more details in the long run. So when you zoom in to see the finer details you will be able to see them allot better. This is one of the biggest changes I would make.
2. If you have a Tone Correction adjustment setting. Set it to high contrast. This creates an S curve. It sounds complicated but its not. If you cant find the setting in you're supplied scanning software just contact me and I will try and help you out. Again this really makes the bill look a little richer without actually changing it all that much.
3. Dust Removal Setting should be set to high. It will vary from scanner to scanner but this makes a huge difference in the long run. Nobody wants to see dust when looking at their Banknotes.
4. *Important* When scanning you're banknotes make sure you do it in a medium to dark lit room with you're flatbed lid open not closed! The black background that this creates really makes you're banknotes stand out even more.
5. Crop you're images nicely. I usually crop to the edges of the holder. Export as JPG format.
Once you have everything setup and ready to go you can usually save you're settings so you dont have to configure it every time. I would suggest experimenting to see what works best for you. But overall the settings I have mentioned above are a really good starting point to work from. What im writing is a product of hours and hours of testing to see what works best.
If you have any questions at all feel free to contact me and I will try and help you out as best I can. Im going to now show you two scans of the same banknote, one on the factory settings one on my optimized settings. Some may say they dont see the difference but the devil is in the details!
The first image is with factory settings and the second image is optimized with my settings.
Hope this helps. Cheers!
