Page 49: Effective Exposure Area
Chapter 4 Basic Operation 7. Effective Exposure Area When loading the plate onto the drum of the PT-R, clamps are used to secure the leading and trailing edges. For this reason, the parts of the plate that are hidden by or in the shadow of the clamps cannot be exposed by the laser.

PT-R4300 USERS MANUAL 8.3 Set Next Plate while Exposure is in Progress Insertion and ejection of plates is performed on the PT-R using separate insertion and ejection tables, and thus it is possible to set the next plate on the insertion table while exposure is in progress.
Page 55 Chapter 4 Basic Operation When exposure of the previously set plate ends and the plate is ejected, the next plate loads. When loading is completed, the operation door lock releases, the plate removal request screen is displayed, and the buzzer beeps repeatedly. Remove exposed plate and close door.

Page 58: Dot Gain Calibration
PT-R4300 USERS MANUAL 9. Dot Gain Calibration Dot gain (dot thickening) occurs as a result of printing and causes the colors of the exposed material to become darker than the colors specified in the PostScript file. For example, a 50% PostScript tint on the screen increases from 65% to 80% when printed on paper due to a dot gain of 15% to 30%.
Page 59 Chapter 4 Basic Operation The general methods for calibrating a plate exposed with the PT-R are as follows: • Perform linear calibration on the plate. The dot area on the plate will not be exactly equal to that of the PostScript file. When creating a linear plate with the PT-R, perform linear calibration (note that there are some media types that do not require linear calibration).
