When it comes to lithography, there are two types of presses that can handle the printing: web presses and sheetfed presses. Each has advantages and is better suited for certain projects.
Definition
A web press is one that images onto continuous rolls of paper at very high speeds. A sheetfed press, on the other hand, prints onto cut-size sheets of paper.
Colors
Both web and sheetfed presses are manufactured with varying numbers of inking towers. The number of towers dictates the number of ink colors that can be applied during a pass. Sheetfed presses offer the flexibility of imaging sheets a second time to add even more colors.
Run Length
Web presses are more cost-effective for long press runs (20,000 impressions or more) because of their speed. Conversely, sheetfed presses are the better choice for short runs and small projects such as stationery and business cards.
Stock Choices
Sheetfed presses can print a wider variety of stocks including heavier weights and broader color selections. Continuous rolls of paper for web presses are not manufactured in thicker weights or in as many colors. Web presses work better for printing on very lightweight papers.
Quality
Both web and sheetfed presses are capable of producing very high quality images. Lack of color registration can affect both and is controlled by the press operator.
Finishing
Web presses can also fold and finish many print projects such as newspapers. When using a sheetfed press, folding and other finishing operations must be done offline as additional steps.
