Digital printing has a higher cost per page than more traditional offset printing methods, but this price is usually offset by avoiding the cost of all the technical steps required to make printing plates. It also allows for on-demand printing, short turnaround time, and even a modification of the image (variable data) used for each impression. [2]
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.
Prepress is the term used in the printing and publishing industries for the processes and procedures that occur between the creation of a print layout and the final printing. The prepress process includes the preparation of artwork for press, media selection, proofing, quality control checks and the production of printing plates if required.
To understand how the pages are related to each other, an imposition dummy may be used. This is made by folding several sheets of paper in the way the press will print and fold the product. A little copy is then created, and this can help paginate the product. [1] In the example above, a 16-page book is prepared for printing.
Print on demand with digital technology is a way to print items for a fixed cost per copy, regardless of the size of the order. While the unit price of each physical copy is greater than with offset printing, the average cost is lower for very small print jobs, because setup costs are much greater for offset printing.
This printing plate is mounted onto the plate cylinder within the printing unit which again is part of the printing tower. Modern presses can print full color on every page. Four color printing units are used for printing on one side of the paper web and another four printing units apply the backside print onto the paper web.
In printing, trap expresses the degree to which ink already printed on a substrate accepts another layer printed on top of it compared to how well the substrate (e.g., paper) accepts that ink. However, in the era of prepress software, the term came to refer to compensation for misregistration (when two layers of ink are not perfectly aligned ...
The 910-ton printing presses at the Las Vegas Review-Journal were the largest in the world when installed in 2000. Offset printing is a widely used modern printing process. This technology is best described as when a positive (right-reading) image on a printing plate is inked and transferred (or "offset") from the plate to a rubber blanket.
