150 line screen

[mknjr11]

Hello everyone,
I am new to this forum so I am hoping this is the place to post this question.
My company is using the conventional plate making system and we are currently running 150 line screen. We would like to go up to 175 or even 200, is this possible, and what kind of settings do we need to use in our prepress department and plate making to achieve these results. Thanks for any help that you can provide.

I am in a shop that did that two years ago we went conv. 133 to digital 200lpi
however we went back to 175 max because our press men could keep it consitant ie. water ink balance ,slur, impresion they never looked at the dot just the den. "which was always off" now running ECRM Mako4 CTP and Fuji Brillia plates and Couldn't be happier 3-97% dot very const. 2-98% @150lpi

when we were running 200 lpi (because the prod. mang. thought it was better) whe had elipitcal dots @ nominal +7.5 angle looks good when ran right however in my opinion most of our cust never saw a difference mabey if they looked under a lupe they would but not as a printed peice

I'd stay between 150 and 175 lpi with round dot and nominal angle to help the pressmen (unless you have qualified press operators who look at what they print)

just my two cents I may be wong

You want to go 200 line with FLEXO??
Conventional plates???
Digital maybe.
Most of our flexo clients can barely print 120 lines from conventional plates. The better ones can handle 150-175 from digital plates.
We're talking 4/c (at least) process work?

Yes 4 color. We are trying to get the best quality we can without going the expensive route of Digital at the moment. If 175 is the best, than that's what we will do. We just want to make sure all our settings are correct (curve etc.) for optimum quality.
