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.

Quality checking 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.
