Linear Plate Curves

[Skinflint]

Does any one run linear plates at press or run with compensation?

We run linear plates at press but we print mostly text only.

Compensation, that way we can output standard dotgain.

Can I ask what you are getting across the steps for CMYK dot gain after compensation?

Just stick to the ISO curves, depending on the papertype
Consult ISO12647-2-2004 (+ Amm1 2007).
For PT1 (coated) curve A for CMY= 14% (50%) and B for K = 17%.

I advise to hire a certified color consultant for generating curves , as it involves much more then just measuring a few patches !

Depends on target...or not

Depends on target...or not

Linear or compensated plate curves depend on what, if anything, you're targeting. I'm in the "G7" camp which means using a compensation curve to target the G7 NPDC curve (Neutral Print Density Curve). Just did 3 presses last week where we were able to hit gray balance without needing to offset the CMY curves.....so one curve for CMY and another one for K. Doesn't always happen that way but in this case the ink/paper/press combination was able to achieve decent gray balance while still hitting our targets for primaries and secondaries. Nice when that happens!

Anyway, the question really comes down to if you intend to target a specified printing condition. I would suggest you should. WHAT that target should be depends on what region you're in and what sort of customers you're serving.

We run with compensation. The tone curves in our RIP look nearly linear for coated stock, though.
