APOGEE > Apogee Calibration and Simulation Advanced Tutorial

# :Apogee Calibration and Simulation Advanced Tutorial

In this Advanced Tutorial you will learn how to create and work with calibration and simulation curves.

A calibration curve is applied to an output device in order to compensate for discrepancies between the desired and the actual output result. In other words, a calibration curve compensates for dot gain and other deviations on the printing press.
A simulation curve is a calibration curve for special needs, e.g. a fast and easy way to compensate for a certain dot gain. It does not contain measured values, only wanted values. In this Advanced Tutorial you will use a simulation curve to increase or decrease the dot gain compensation of the calibration curve.
The maximum amount of dot gain that is accepted for a press is 15%. If more dot gain is measured on paper, you should use a calibration curve. Too much dot gain can occur when using special ink, special paper, a special press device or a special screen.
Each curve has an impact on the output result. If you use a calibration curve and a linearization curve, both curves will influence the result. Even if you choose a simulation curve, this will influence the output.

The first lesson of this tutorial is fully available in the sample file. ###### Tutorial Objectives

This Advanced Tutorial is divided into a series of 10 lessons (34 pages). In these lessons, you will learn how to:

• Create a calibration curve in order to compensate for dot gain on the printing press.
• Enter the measured values from a test page in order to edit a calibration curve.
• Edit the calibration curve for the yellow separation only. You will reset the original yellow compensation values and replace them with the test page values.
• Use a calibration curve, and check its results in a processed document.
• Map a calibration curve: :APOGEE Prepress can automatically select the best calibration curve from one of the maps you create, based on screen type, resolution, frequency, dot shape, paper type and ink set defined in the job.
• Configure :APOGEE Prepress to automatically select the correct mapped calibration curve for the processing of your document, depending on the job settings.
• Import calibration curves in :APOGEE Prepress.
• Create a simulation curve in order to quickly and easily compensate for dot gain for all separations of the output.
• Combine a calibration curve with a simulation curve.
