Aztek 8000 Premier, orange/yellow cast near image edge + scan lines

Outside the box I would check the illuminator and the lamp alignments.

Thanks – that's what Evan from Azrek also suggested. I will try this next time I drive out to where the scanner is.

Is this THE aztek Premier aka top of the line 8000 DPI?! I've read that this machine suffers from underpowered light source, people have gone as far as to modify the source with higher powered LEDs for scanning 8000 and smallest aperture.

This is like opposite, too much light or too much in uncontrolled way (re possible fibre alignment issue or other). I think obvious question here is what aperture is OP using?

Perhaps the engineers had this in mind when designing machine, trying to optimise it for use with 8000 DPI and smaller apertures yet still had problems and compromises? Design is about compromise after all..

19

19

19, as in smallest or largest? Sorry not that familiar with DPL or howtek/aztek in general. Unless you are talking about 19microns...

Aperture isn’t the same than sampling. Scanning with a 19 microns aperture limits the optical resolution to around 1333 dpi. You can save a file at 4000 dpi but still the resolving power will be limited to 1333 dpi.

Hi mate, sorry not sure where you draw that from my post. I know aperture more or less directly correlates to resolving power among other things. I said 8000DPI @ smallest aperture aka 3microns which in theory should be maximum resolving/sampling rate of machine which I respect is way above any normal film.

My comments re aperture purely relate to light throughput, sorry for the confusion. If the scans were made at the largest aperture, I suspect issues would be much worse then if done at smallest aperture. I do hope OP gets to bottom of issue (I was looking at an aztek) just curious if it is in line my current conspiracy theory

I was referring to the OP mentioning the scan been done 4000 dpi.

Ahh, apologies for the confusion all good. Just re-read the OPs post for clarities sake too...
Well, do you know what the OP means by "19" since you have some experience with the machine and DPL itself? Would really like to know
