Hi All!
I am Ali, anyone can tell me that how to check printing quality on paper/Card.
Please guide me properly.

What exactly are you printing and what press are you printing with?

If you could give a little more background on what equipment you're using and what result you need to achieve or what problems you are encountering I'm sure many here could give you some ideas.

Thanks for reply!
We have these machines in our Press:
1- Roland "25x36" (1-Color)
2- Pearl "19.5x29.5" (1-Color)
3- Solna 125 "18x25" (1-Color)
4- Solna 225 "18x25" (2-Color)
5- Rota
How can get maxium quality of printing from these machines or what should keep in my mind for checking quality.

I hope, you understand above lines beacuse English is not my mother language.

Thanks & regards
Ali

First you need a densitometer - to check solid ink density, dot gains for the halftones or dot area.

SWOP- specifications for web offset printing - the solid ink densities are specified by this org. that includes dot gain and its grey balance. This is the specifications followed by US printers.

ISO coated - this is more stricter than SWOP. But this one has deeper color or better color gamut in a sense.
