If you convert, there is no need for testing. This is correct. I assumed you were starting a new line of products or restarting an old line akin to the work of Mirko and M&P. Of course, I cannot comment on their schedules or work as I know nothing about it except what is posted.
It seems to me that many of the so-called new products marketed by Roelli/Maco are in fact existing emulsions currently made by AgfaGevaert or FilmoTec, just converted and packaged in consumer sizes. This method of bringing products to market would still require $, as there would be minimum orders to meet, I'm sure.
