I would like to get his done by RT - but i am newbee and i will go further to get results …
Second step is to reach the width of file which i want to get for proper printing (5000 px). For this i use an old programm with name smilla enlarger, which does a good job, but perhaps this job could also be done by RT?
I found out that using the Black-slider in the exposure tab gives best results with ~ 20.000.
But i must confess that the results are somehow away from the original.
Some pp3 files were given from very generous members of the forum and i tried them all.
I hope to combine the steps of dxo and smilla. Perhaps RT can do that?
Thanks for your time!

Here is the full page result I get from my test G’MIC filter using the exact same settings as before. Of course, the parameters can be tweaked to make it look better. It performs best when it has been cropped beforehand.
I tried myself using Gimp and the plug-in.
Two filters are great:
Sharpen (Octave Sharping) and
Iain’s Noise Sharping
With those two i try some files now.
Btw. the original scans from the library have only poor resolution. What do you think is better:
First increasing resolution and than processing?
or
First processing and after that increasing resolution?
I keep in mind that every step will create false data. This data will be increased also. But what is your opinion about that?
Can you please explain how you make two different filters on one scan? Do you write it to a new file, leaving G’MIC open and then for the second instance you start with this new photo on the second filter? Or do you write the results to different levels and combine them later?
I have a bunch of scans here and i want to make it more easier with shortcuts. Batch is not possible, because i have to look after every scan individually.
Maybe I’m more clumsy. I push the OK-button after a filter. Then I view the result in GIMP, because the end result is sometimes different from the preview. In this case I continue with the last result and restart G’MIC for the next filter.
1. I have changed the category to Processing and added the tags gmic, rawtherapee, scanner. I think we have room to discuss how to make better scans.
2. iarga is correct. Clean Text is available as a GIMP-G’MIC plugin filter and also as a CLI command (afre_cleantext). Unfortunately, I am having trouble retrieving it from the servers. I don’t know if you have the same issue ATM when you try updating the filters. Do the following:
For GUI plugin
Then search for Clean Text.
For CLI
gmic update
gmic sample tiger afre_cleantext
3. You can totally do batch work using the GUI or CLI. Try the filter on the two most different scans and find a happy medium.
Then in GIMP, Open as layers..., in the plugin, set Input layers as All, and then you could apply the filter to all of the pages.
Or in CLI, you could copy all of the scans to a single new folder and do
Hint: replace the comma with your parameters. The comma by itself means that it will use the default values I have set.
PS If you found my filter and instructions helpful, perhaps we could as a community write a tutorial together, with instructions on how to digitize a book. I don’t have the time for that currently but what do you think @patdavid@paperdigits?
Yesterday I had a few times the same error. This doesn’t help you, but now you know that you are not doing anything wrong. Maybe this has something to do with the G’MIC server?
