i have mako ctp with 150 output.
But all the job print out look too dark on mid too and shadow.

Before you consider choosing one ICC profile or another make sure you calibrated the laser output and linearized your percentage on plate. Best to talk to your local rep about the procedure to follow, nothing sophisticated anyway.

<<nothing sophisticated anyway>>... if they have a densitometer for Lithostar plates

Vlad, he didn't mention Lithostar.

Kenhew, a plate gauge / step wedge is a must depending on the plate type, Stouffer, UGRA 1982 or whatever his plate supplier says. Also a platereader to check dot percentage. The two things are mandatory for basic quality control.

Kenhew, you just need to use a curve at plating that opens up the mid-tones for jobs printed on uncoated. Not tough to do.
