Ok, Ok, Ok,

Lete me think this through.

1. plate copper polymer
2. image film positive both
3. rosin copper
3. stochastic screen polymer
4. rosin exposure copper screen exposure polymer
5. image exposure onto tissue copper image exposure on to polymer plate
6. etch the plate copper washout the plate polymer
7. prep the plater same/same
8. ink the plate same/same
9. print the plate same/same
10. clean up I hate cleanup polymer use baby oil
11. store lite coat of baby oil light coat

What am I missing Names copper gravure polymer gravure

Time longer time to failure with copper shorter time to failure

Press run ? more prints with copper Less prints with polymer

Ending thoughts like Darryl said we are spliting some fine hairs

thanks for your time and this space
