Re: Scanner problems
I'm not sure what you've have or haven't tried, but here are a few suggestions that might help.
First of all, save your file in a 'TIFF' or 'RAW' format. Saving your files in JPEG format will be converted to 24-bit and you'll lose the 48-bit image quality you desire.
Second, make sure that your scanner is set for 48-bit and not 24-bit. Most scanners give you the option of 24 or 48 bit, so ensure yours is set for 48.
Third, the Epson software gives you the option of selecting either a 'Home' mode or a 'Professional' mode. 'Professional Mode' will give you a much larger set of options to configure your scanner to better compensate for your issues. In 'Professional Mode', you should be able to adjust things like Saturation levels, Color Balance, Auto Exposure, Tone Correction, and Color Palette.
And fourth, don't hesitate to do a print head nozzle check and a print head cleaning on occasion. These can make a big difference if either are dirty or plugged.
Hope this helps.
