I couldn't find any recent posts regarding Chromira print quality vs. Lightjet prints.

One post suggested that the each printer produces slightly different color gamuts and the colors needed would determine the choice of printer?

There is also some debate as to the input resolution that is optimal for each printer.

Some say that 250ppi is sufficient for the Chromira rather that 300 ppi. Some people feel that 200ppi is enough for the Lightjets as opposed to 304.8ppi?

My idea is to have a number of archival size scans of 4x5 transparencies made to be able to produce high quality prints up to 32 x 40, so trying to determine the optimal printer input file size will help with scanning service choices.

All opinions are appreciated.
