*Recordings are done by automatic measurement mode
/25 36
For consistence Printing DG,plate controls is obligatory
Every week produce a test plate which has a “plate scale” job on it.
Plate Scale
Measurements are done and recorded by a plate measurement device. Then the program calculates the dot gain of the plate
%2, %98 and % 50 tone values are measured with plate densitometer by the prepress man to understand if there is an abnormality or not. If the values are seem to be changed, he produce a test plate for exact measurement and calibration
Daily Plate Checking
A tone scale stays on the bended side of the plates is checked daily.Plate is taken before P&B machine for measurement.

Plate + Press
Applied dot gains
While the Q. Engineer evaluates and records the print defects to ERPVideo-2 : B Printing Defects Checking
So ; we are checking ourselves like we are in competition INCQC everyday
B Printing Defects Checking
First run or restart - following a stop copies:
Customers complains mostly :from the “startup “ newspapers or “restart - following a stop ” newspapers.
Because mechanically they are the worst.
salable , low quality, not salable,
B Printing Defects Checking
C Consumabels Reporting a) are being used (Current)
Ex: Newsprint Evaluation Reportb) Test metarials
Target is;To prepare a list to our purchasing department.Show preferred and not preferred
So we ask: not to bought unwanted, instead, the preferred if possible much
