Are offset lithographs worth anything?
An offset lithograph may not be worth as much as a hand lithograph because it is usually a copy of an original. The hand lithograph is either done directly by the artist or it is done while being supervised by the artist. The artist will decide only to produce 150 prints for instance.
What is the difference between offset and litho printing?
An offset print is any type of lithograph that is created using an offset press. Offset lithography uses a similar tactic as original hand lithography based on oil-and-water repulsion; however, with an offset press, the ink is transferred first to a rubber blanket and then directly applied to either stone or paper.
How does offset ink dry?
Offset inks use both methods of drying, but dry predominantly by one method or the other. Van Son Rubber Base Plus inks dry 100% by absorption, making it suitable for all uncoated stocks. Van Son Quickson offset offset inks dry 50% by absorption and 50% by oxidation. It can be used on coated and uncoated stocks.

Why does an offset printer Print on a flat surface?
That means the surface from which you print is completely flat. This is feasible because of a very useful chemical principle: offset printing ink is an oily substance, which means it repels water. If you can create a surface on which some parts contain a thin layer of water, those areas will repel ink.

Offset printing is based on the idea that the image area to be printed should be transferred from a “plate” to a rubber blanket, and then to the sheet of paper. Offset printing is “wet” in that it uses a wet ink, usually either based on rubber or oil. At The Print Authority, we use oil based inks.
Is there advance proof for full color offset printing?
For full color offset printing, there is no advance proof which will produce exactly the same colors as the final printed piece. For color critical projects, you can do a press check. In a press check, the client sees the first sheet off of the press. Once approved, we print the remainder of the project.
