Best Practices PiezoDN Pro K5C K4W


#1

Just want to confirm best practices here for PiezoDN with Piezography Pro ink.

Am going to linearize for silver using a K5 Cool / K4 Warm setup. Would it be better to just use the K4 master curve, or to map the K4 warm ink curves from that (beta) master to the K5 (beta) master? Is the difference likely negligible and not worth the effort, or even counter-productive?

My first step after clarification on the above, was going to be to use the Limiter before the 129 Step chart.

Another question: it seems the Pro beta master curves are not using GCO, where the earlier PiezoDN curves used GO to make the negative more robust. Are the new inks more robust, or would one want to be more careful with these negatives?

Thanks,

Andrew

The difference between the K5 and K4 is negligible. I suggest going just with the K4 if you are down a channel.

Yes. It will most likely need to be limited w/ Silver. Also, you may find that you need to set your platen gap to Narrow and your paper feed speed to -10 to make sure the "grain" is minimized.

Another question: it seems the Pro beta master curves are not using GCO, where the earlier PiezoDN curves used GO to make the negative more robust. Are the new inks more robust, or would one want to be more careful with these negatives?

GCO is not needed with Pro ink, it is much more robust than older generation ink and we decided that addition of GCO only adds print cost and does nothing to increase durability.
