Offset Specification and Logical Page Size Explained

The two sets of numerical values that make up the Offset Specification and the Logical Page Size are dependent on two variables:

1.The DPI (dots per inch) selected in the imposition file, which can be either:

300x300 DPI or;

600x600 DPI

2.The width of the logical page (image area) being printed.

Note

In the following paragraph, it mentions that a logical page size of 5.6 in (142 mm) by 12 in (305 mm) is used. This is because 5.6 in (142 mm) by 12 in (305 mm) is the size of the test pattern printed to perform color calibration using the Xerox 490/980 Color Continuous Feed Printing System SIR.

Later in this chapter, there is a Table of Offset Specification and Logical Page Size Values. This table shows the numerical values for the Offset Specification and Logical Page Size for widths of paper stock from 8.3 (211 mm) in to 19.5 in (495 mm) and a logical page size of 5.6 in (142 mm) by 12 in (305 mm).

If the width of the paper stock you are using is not covered in the Table of Offset Specification and Logical Page Size Values, use the sample procedure in the section Calculate Offset Specification and Logical Page Size Values to determine the appropriate numerical values.
