Characteristic of offset printing unlike many other printing techniques is the ability to print on different types of print media. This characteristic of offset printing is possible due to the rubber sleeve on the portable cylinder that perfectly adapts to different weights, roughness and qualities of print media. Quality of offset printing changes depending on what printing substrate we are printing. Not all printing substrate can achieve the same quality. On some surfaces can not be achieved quality as good as soft proof laser printer. One of the key features is the ability to accept printing ink to the printing surface. This ability is reflected in the printing options with a higher or lower density inks, and the greatest impact on the quality of a printing have substrate that is directly related to the drying inks. When the printing surface is smaller quality, the ink which is applied to the surface need to be smaller. In these cases, we use the UCR or GCR method while we screening in prepress or the possibility of changing the density tints during printing. Each printing substrate has specific characteristics that affect the acceptance of color and reflection from the surface which has an impact on the final experience of printing quality.
