I have micropgraphs (fotographs taken through a microscope) in high resolution (3000x2000), 24 bit per pixel color depth. TIFF format.
I insert them into my scribus document, into rather small image frames, i.e. I think the images are downscaled quite heavily (which is intended, I want to preserve as much info as possible).
The goal is to generate PDF.
When I generate the PDF, the micrographs look very "flat", as if they have lost a lot of color, and fine details are not discernible anymore.
I do *not* think this is a problem with the micrographs themselves because when I downscale them in IrfanView with lanczos filter they still look very good with all color and details, even if I do extreme downscaling.
I tried a few diffferent parameters during the PDF export in scribus (lossless compression instead of lossy etc) to no effect.
Is there any way how I can retain full image quality? It is important to me that all the small details and color changes are still discernale in the PDF. Again, I do not think it is the downscaling per se, but I believe it must be related to Scribus because downscaling in other programs still retains the crucial information. Thanks.
