Symptoms

Images created from a "Folder" Import Processor and converted to tiff using Ghostscript have poor image quality compared to using an "Email" Import Processor using Ghostscript from a script, even though Ghostscript setting is the same.  The images from the "Folder" Import Processor are failing to extract data in Oracle WebCenter Forms Recognition.

Email Import Process:
1) Conversion of pdf - > tiffgray using Ghostscript (-q -dNOPAUSE -dNumRenderingThreads=4 -r300 -sDEVICE=tiffgray -sCompression=lzw -sOutputFile=<Output File> <Input File> -c quit )
2) Conversion of tiffgray -> TIFF B/W (doc conversion)

In both processes, the JPEG quality is not used.
